  • using Unity Android In a sub view and add style and actionbar

    - by aeroxr1
    I exported a simple animation from Unity3D (version 4.5) in android project. With eclipse I modified the manifest and added another activity. In this activity I put a button that it makes start the animation,and this is the result. The action bar appear in the main activity but it doesn't in the unity's activity :( This is the unity's activity's code : package com.rabidgremlin.tut.redcube; import android.app.NativeActivity; import android.content.res.Configuration; import android.graphics.PixelFormat; import android.os.Bundle; import android.view.KeyEvent; import android.view.MotionEvent; import android.view.View; import android.view.ViewGroup; import android.view.Window; import android.view.WindowManager; import com.unity3d.player.UnityPlayer; public class UnityPlayerNativeActivity extends NativeActivity { protected UnityPlayer mUnityPlayer; // don't change the name of this variable; referenced from native code // Setup activity layout @Override protected void onCreate (Bundle savedInstanceState) { //requestWindowFeature(Window.FEATURE_NO_TITLE); super.onCreate(savedInstanceState); getWindow().takeSurface(null); //setTheme(android.R.style.Theme_NoTitleBar_Fullscreen); getWindow().setFormat(PixelFormat.RGB_565); mUnityPlayer = new UnityPlayer(this); /*if (mUnityPlayer.getSettings ().getBoolean ("hide_status_bar", true)) getWindow ().setFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); */ setContentView(mUnityPlayer); mUnityPlayer.requestFocus(); } // Quit Unity @Override protected void onDestroy () { mUnityPlayer.quit(); super.onDestroy(); } // Pause Unity @Override protected void onPause() { super.onPause(); mUnityPlayer.pause(); } // eliminiamo questa onResume() e proviamo a modificare la onResume() // Resume Unity @Override protected void onResume() { super.onResume(); mUnityPlayer.resume(); } // inseriamo qualche modifica qui // This ensures the layout will be correct. @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); mUnityPlayer.configurationChanged(newConfig); } // Notify Unity of the focus change. @Override public void onWindowFocusChanged(boolean hasFocus) { super.onWindowFocusChanged(hasFocus); mUnityPlayer.windowFocusChanged(hasFocus); } // For some reason the multiple keyevent type is not supported by the ndk. // Force event injection by overriding dispatchKeyEvent(). @Override public boolean dispatchKeyEvent(KeyEvent event) { if (event.getAction() == KeyEvent.ACTION_MULTIPLE) return mUnityPlayer.injectEvent(event); return super.dispatchKeyEvent(event); } // Pass any events not handled by (unfocused) views straight to UnityPlayer @Override public boolean onKeyUp(int keyCode, KeyEvent event) { return mUnityPlayer.injectEvent(event); } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { return mUnityPlayer.injectEvent(event); } @Override public boolean onTouchEvent(MotionEvent event) { return mUnityPlayer.injectEvent(event); } /*API12*/ public boolean onGenericMotionEvent(MotionEvent event) { return mUnityPlayer.injectEvent(event); } } How can I add the action bar and the style of the first activity to unity's animation activity ?

  • How can i make a gallery with web images from my website?

    I currently have two codes that i am trying to figure out how to mix or write a new code to have a gallery with image doing fill_parent but i can slide sideways to see the other url linked images from my site. here are both parts of code i have: package com.mandarich.gallerygrid; import java.io.InputStream; import java.net.URL; import android.app.Activity; import android.graphics.drawable.Drawable; import android.os.Bundle; import android.widget.ImageView; public class Gallery extends Activity { /** Called when the activity is first created. */ public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ImageView imgView =(ImageView)findViewById(R.id.ImageView01); Drawable drawable = LoadImageFromWebOperations("http://www.mandarichmodels.com/hot-pics/"); imgView.setImageDrawable(drawable); } private Drawable LoadImageFromWebOperations(String url) { try { InputStream is = (InputStream) new URL(url).getContent(); Drawable d = Drawable.createFromStream(is, "src name"); return d; }catch (Exception e) { System.out.println("Exc="+e); return null; } } } and here is my gallery code package com.mandarich.Grid; import android.app.Activity; import android.content.Context; import android.content.res.TypedArray; import android.os.Bundle; import android.view.View; import android.view.ViewGroup; import android.widget.AdapterView; import android.widget.BaseAdapter; import android.widget.Gallery; import android.widget.ImageView; import android.widget.Toast; import android.widget.AdapterView.OnItemClickListener; public class gridfinal extends Activity { private Gallery gallery; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); gallery = (Gallery) findViewById(R.id.examplegallery); gallery.setAdapter(new AddImgAdp(this)); gallery.setOnItemClickListener(new OnItemClickListener() { @SuppressWarnings("unchecked") public void onItemClick(AdapterView parent, View v, int position, long id) { // Displaying the position when the gallery item in clicked Toast.makeText(gridfinal.this, "Position=" + position, Toast.LENGTH_SHORT).show(); } }); } public class AddImgAdp extends BaseAdapter { int GalItemBg; private Context cont; // Adding images. private Integer[] Imgid = { R.drawable.cindy, R.drawable.clinton, R.drawable.colin, R.drawable.cybil, R.drawable.david, R.drawable.demi, R.drawable.drew }; public AddImgAdp(Context c) { cont = c; TypedArray typArray = obtainStyledAttributes(R.styleable.GalleryTheme); GalItemBg = typArray.getResourceId(R.styleable.GalleryTheme_android_galleryItemBackground, 0); typArray.recycle(); } public int getCount() { return Imgid.length; } public Object getItem(int position) { return position; } public long getItemId(int position) { return position; } public View getView(int position, View convertView, ViewGroup parent) { ImageView imgView = new ImageView(cont); imgView.setImageResource(Imgid[position]); // Fixing width & height for image to display imgView.setLayoutParams(new Gallery.LayoutParams(430, 370)); imgView.setScaleType(ImageView.ScaleType.FIT_XY); imgView.setBackgroundResource(GalItemBg); return imgView; } } }

  • How does one get rid of fishy behavior in Windows?

    - by Tom Wijsman
    After I had boot my computer this morning there suddenly flooded water from the top of the screen, after which some fishes dropped into it. Now I can barely see what I am doing because the water distorts the view. Sometimes the fish follow the cursor so I need to move it away or wait for the fish to mind their own business. This makes it very annoying to use my system. What have I tried? Reboot the system. This caused the water to deplete from the desktop. Upon reboot, the screen was refilled with water and fishes. Attach another monitor. Same problem, fills that monitor as well and gives me extra fish. Clicking the fish. Makes them turn direction. Right clicking the fish. Changes color of the fish, not really useful. I'm locked out of changing the background or screen saver settings. Hence, I had to post the lady below... Safe mode doesn't save me from the fishes. It does give me another background there, but I can't screenshot easily. Other user accounts experience this as well. The Guest account seems to experience more fish than the other accounts. Using HijackThis, OTL Timekeeper List, Syninternal Autoruns, RootKitRevealer, ShellExView and similar tools I can't seem to find any entries that could be it, the Sysinternals tools show everything as verified. I'm suspecting this to be a driver problem. Randomly removing drivers doesn't seem to alleviate the problem. When removing the Graphics Drivers, it makes my screen black. While that could be considered the solution, it's not what I want. Changing the time / date settings does also not seem to affect the fishes. Changing the time a few years in the future, I would have expected the fishes to be dead. But, the same fishes are still there... They simply won't die! Tried to get used to them. They are really bothering me, looks like they require food. I don't know how to give them food, but apparently they get it elsewhere during reboot... Tried to disable my mouse pointer and use the keyboard. This works, they now swim around more randomly. They do put their attention to huge changes on the screen, so I need to type slow. Or otherwise I can't see what I'm tying exactly. Hold my laptop upside down. This seems to affect the water and fishes, but the water stays in the screen. They seem super resistant against water sickness and confusion though... What does the problem look like? What do I need? A way to get rid of these fishes on my screen forever, they are really annoying me a lot and I'm about to crack the screen to see if that makes them escape. Do you have any idea why this problem is occurring? What are my considerations? Buying an USB fish tank could make the fish leave the screen, I am uncertain though whether the fish could leave the screen through the USB cable. Using the FISh (programming language) which seems to provide EXPRESSIVE POWER and EFFICIENT EXECUTION, I can however not find any examples on how to remove fish. What are my Specifications? I'm using a Sony Vaio Fishy laptop. Sony VAIO VGN-Fishy, VAIO. Processor: 1337 MHz, Intel Core 2 Duo, T5432, 1 MB, Intel PM965 Express, 667 MHz.

  • Proper network configuration for a KVM guest to be on the same networks at the host

    - by Steve Madsen
    I am running a Debian Linux server on Lenny. Within it, I am running another Lenny instance using KVM. Both servers are externally available, with public IPs, as well as a second interface with private IPs for the LAN. Everything works fine, except the VM sees all network traffic as originating from the host server. I suspect this might have something to do with the iptables-based firewall I'm running on the host. What I'd like to figure out is: how to I properly configure the host's networking such that all of these requirements are met? Both host and VMs have 2 network interfaces (public and private). Both host and VMs can be independently firewalled. Ideally, VM traffic does not have to traverse the host firewall. VMs see real remote IP addresses, not the host's. Currently, the host's network interfaces are configured as bridges. eth0 and eth1 do not have IP addresses assigned to them, but br0 and br1 do. /etc/network/interfaces on the host: # The primary network interface auto br1 iface br1 inet static address 24.123.138.34 netmask 255.255.255.248 network 24.123.138.32 broadcast 24.123.138.39 gateway 24.123.138.33 bridge_ports eth1 bridge_stp off auto br1:0 iface br1:0 inet static address 24.123.138.36 netmask 255.255.255.248 network 24.123.138.32 broadcast 24.123.138.39 # Internal network auto br0 iface br0 inet static address 192.168.1.1 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 bridge_ports eth0 bridge_stp off This is the libvirt/qemu configuration file for the VM: <domain type='kvm'> <name>apps</name> <uuid>636b6620-0949-bc88-3197-37153b88772e</uuid> <memory>393216</memory> <currentMemory>393216</currentMemory> <vcpu>1</vcpu> <os> <type arch='i686' machine='pc'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file' device='cdrom'> <target dev='hdc' bus='ide'/> <readonly/> </disk> <disk type='file' device='disk'> <source file='/raid/kvm-images/apps.qcow2'/> <target dev='vda' bus='virtio'/> </disk> <interface type='bridge'> <mac address='54:52:00:27:5e:02'/> <source bridge='br0'/> <model type='virtio'/> </interface> <interface type='bridge'> <mac address='54:52:00:40:cc:7f'/> <source bridge='br1'/> <model type='virtio'/> </interface> <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target port='0'/> </console> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/> </devices> </domain> Along with the rest of my firewall rules, the firewalling script includes this command to pass packets destined for a KVM guest: # Allow bridged packets to pass (for KVM guests). iptables -A FORWARD -m physdev --physdev-is-bridged -j ACCEPT (Not applicable to this question, but a side-effect of my bridging configuration appears to be that I can't ever shut down cleanly. The kernel eventually tells me "unregister_netdevice: waiting for br1 to become free" and I have to hard reset the system. Maybe a sign I've done something dumb?)

  • MSBUILD ClickOnce Error: Deployment and application do not have matching security zones

    - by fande455
    We're trying to publish a ClickOnce application through msbuild. We've got it working fine for an installed version of the windows application. However, when we set install to false so that it just runs the app from the web we get the following error when we try to run the application from the URL: "Deployment and application do not have matching security zones" This works fine in IE. We only get the error message in Chrome and FireFox. Here is a sample of the project file settings. <Project DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003" ToolsVersion="3.5"> <PropertyGroup> <SrcTreeRoot>$(MSBuildProjectDirectory)\..\..\..</SrcTreeRoot> <!--ClickOnceDeployFolder>$(WebOutputDir)\AnalyzerPC</ClickOnceDeployFolder--> <ProjectGuid>{8205E593-F400-41AE-8D6F-DEA290B2DCF9}</ProjectGuid> <Configuration Condition=" '$(Configuration)' == '' ">Debug</Configuration> <Platform Condition=" '$(Platform)' == '' ">AnyCPU</Platform> <ApplicationIcon>Graphics\EDA Icon.ico</ApplicationIcon> <AssemblyName>DASHQueryBuilder</AssemblyName> <OutputType>WinExe</OutputType> <RootNamespace>TetraData.Analyzer</RootNamespace> <FileUpgradeFlags> </FileUpgradeFlags> <OldToolsVersion>2.0</OldToolsVersion> <IsWebBootstrapper>false</IsWebBootstrapper> <ManifestCertificateThumbprint>...</ManifestCertificateThumbprint> <GenerateManifests>true</GenerateManifests> <SignManifests>true</SignManifests> <SignAssembly>true</SignAssembly> <ManifestKeyFile>$(BuildDir)\Certificates\TetraDataCode.pfx</ManifestKeyFile> <ProductVersion>9.0.21022</ProductVersion> <PublishUrl>http://localhost/DASHQueryBuilder/</PublishUrl> <Install>false</Install> <!--InstallFrom>Web</InstallFrom--> <UpdateEnabled>false</UpdateEnabled> <MapFileExtensions>true</MapFileExtensions> <PublisherName>Follett Software Company</PublisherName> <TrustUrlParameters>true</TrustUrlParameters> <ApplicationRevision>0</ApplicationRevision> <UseApplicationTrust>false</UseApplicationTrust> <PublishWizardCompleted>true</PublishWizardCompleted> <BootstrapperEnabled>false</BootstrapperEnabled> </PropertyGroup> <Import Project="$(SrcTreeRoot)\Build\TaskInit.Tasks" /> <Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" /> <Import Project="$(SrcTreeRoot)\Build\TaskOverrides.Tasks" /> <Import Project="$(MSBuildProjectDirectory)\Analyzer.csproj" /> <PropertyGroup> <PublishDir>$(WebOutputDir)\DASH Query Builder\</PublishDir> <ApplicationVersion>$(MajorMinorVersion).0.0</ApplicationVersion> </PropertyGroup> <Target Name="BeforeResolveReferences"> <Copy SourceFiles="$(MSBuildProjectDirectory)\DASHQueryBuilder.config" DestinationFiles="$(MSBuildProjectDirectory)\app.config" /> </Target> </Project>

  • Delphi - Why is my global variable "inacessible" when i debug

    - by Antoine Lpy
    I'm building an application that contains around 30 Forms. I need to manage sessions, so I would like to have a global LoggedInUser variable accessible from all forms. I read "David Heffernan"'s post about global variables, and how to avoid them but I thought it would be easier to have a global User variable rather than 30 forms having their own User variable. So i have a unit : GlobalVars unit GlobalVars; interface uses User; // I defined my TUser class in a unit called User var LoggedInUser: TUser; implementation initialization LoggedInUser:= TUser.Create; finalization LoggedInUser.Free; end. Then in my LoginForm's LoginBtnClick procedure I do : unit FormLogin; interface uses [...],User; type TForm1 = class(TForm) [...] procedure LoginBtnClick(Sender: TObject); private { Déclarations privées } public end; var Form1: TForm1; AureliusConnection : IDBConnection; implementation {$R *.fmx} uses [...]GlobalVars; procedure TForm1.LoginBtnClick(Sender: TObject); var Manager : TObjectManager; MyCriteria: TCriteria<TUser>; u : TUser; begin Manager := TObjectManageR.Create(AureliusConnection); MyCriteria :=Manager.Find<TUtilisateur> .Add(TExpression.Eq('login',LoginEdit.Text)) .Add(TExpression.Eq('password',PasswordEdit.Text)); u := MyCriteria.UniqueResult; if u = nil then MessageDlg('Login ou mot de passe incorrect',TMsgDlgType.mtError,[TMsgDlgBtn.mbOK],0) else begin LoggedInUser:=u; //Here I assign my local User data to my global User variable Form1.Destroy; A00Form.visible:=true; end; Manager.Free; end; Then in another form I would like to access this LoggedInUser object in the Menu1BtnClick procedure : Unit C01_Deviations; interface uses System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants, FMX.Types, FMX.Graphics, FMX.Controls, FMX.Forms, FMX.Dialogs, FMX.StdCtrls, FMX.ListView.Types, FMX.ListView, FMX.Objects, FMX.Layouts, FMX.Edit, FMX.Ani; type TC01Form = class(TForm) [...] Menu1Btn: TButton; [...] procedure Menu1BtnClick(Sender: TObject); private { Déclarations privées } public { Déclarations publiques } end; var C01Form: TC01Form; implementation uses [...]User,GlobalVars; {$R *.fmx} procedure TC01Form.Menu1BtnClick(Sender: TObject); var Assoc : TUtilisateur_FonctionManagement; ValidationOK : Boolean; util : TUser; begin ValidationOK := False; util := GlobalVars.LoggedInUser; // Here i created a local user variable for debug purposes as I thought it would permit me to see the user data. But i get "Inaccessible Value" as its value util.Nom:='test'; for Assoc in util.FonctionManagement do // Here is were my initial " access violation" error occurs begin if Assoc.FonctionManagement.Libelle = 'Reponsable équipe HACCP' then begin ValidationOK := True; break; end; end; [...] end; When I debug I see "Inaccessible Value" in the value column of my user. Do you have any idea why ? I tried to put an integer in this GlobalVar unit, and i was able to set its value from my login form and read it from my other form.. I guess I could store the user's id, which is an integer, and then retrieve the user from the database using its id. But it seems really unefficient.

  • Can't find the source of an exception in Java

    Basically an exception is being thrown and I can't find the reason.

When thrown nothing is painted. Another interesting thing is the timing of the throwing. I am unable to find any logical patern, as sometimes it is thrown as soon as I initiate the class and sometimes it needs more then five minutes. In addition to this, as far as I tested there is no single action that calls repaint() that triggers it or rather all do. I am new to Java and all the other exceptions had the class and row number of where they were thrown so I don't know what to do here. Any suggestions would be greatly appreciated. The code is enormous so I'll put just the paint method and if anything additional is needed please say so. @Override public void paint(Graphics g) { if(documentLoaded && showingOnScreen){ try{ rad = (int)(radInit+zoom*faktorRad); //max rad = 20 super.paint(g); Graphics2D g2d = (Graphics2D) g; paintElements(g2d); } catch(NullPointerException nulle){ } } } edit: There is no array in my class so i can't check any index. I think that this exception is thrown from a library I use, but it's a .jar file and I don't know how to open it.

  • Xen DomU on DRBD device: barrier errors

    I'm testing setting up a Xen DomU with a DRBD storage for easy failover.

When i click the Button1, it will prompt the confirmation dialog as print screen. My question is how to immediate send mail without prompt the confirmation dialog? Is this possible to achieve?

  • System halts for a fraction of second after every 2-3 seconds

    - by iSam
    I'm using Windows 7 on my HP ProBook 4250s. The problem I face is that my system halts for a fraction of second after every 2-3 seconds. These jerks are not letting me concentrate or work properly. This happens even when I'm just typing in notepad while no other application is running. I tried to install every driver from HP's website and there's no item in device manager marked with yellow icon. Following are my system specs: Machine: HP ProBook 4250s OS: Windows 7 professional RAM: 2GB Processor: Intel Core i3 2.27GHz Following is my HijackThis Log: **Logfile of HijackThis v1.99.1** Scan saved at 9:34:03 PM, on 11/13/2012 Platform: Unknown Windows (WinNT 6.01.3504) MSIE: Internet Explorer v9.00 (9.00.8112.16450) **Running processes:** C:\Windows\system32\taskhost.exe C:\Windows\System32\rundll32.exe C:\Windows\system32\Dwm.exe C:\Windows\Explorer.EXE C:\Windows\System32\igfxtray.exe C:\Windows\System32\hkcmd.exe C:\Windows\System32\igfxpers.exe C:\Program Files\Synaptics\SynTP\SynTPEnh.exe C:\Program Files\PowerISO\PWRISOVM.EXE C:\Program Files\AVAST Software\Avast\AvastUI.exe C:\Program Files\Free Download Manager\fdm.exe C:\Windows\system32\wuauclt.exe C:\Program Files\Windows Media Player\wmplayer.exe C:\Program Files\Microsoft Office\Office12\WINWORD.EXE C:\HijackThis\HijackThis.exe R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = http://go.microsoft.com/fwlink/?LinkId=54896 R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = http://bing.com/ R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Page_URL = http://go.microsoft.com/fwlink/?LinkId=69157 R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Search_URL = http://go.microsoft.com/fwlink/?LinkId=54896 R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Search Page = http://go.microsoft.com/fwlink/?LinkId=54896 R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Start Page = http://go.microsoft.com/fwlink/?LinkId=69157 R0 - HKLM\Software\Microsoft\Internet Explorer\Search,SearchAssistant = R0 - HKLM\Software\Microsoft\Internet Explorer\Search,CustomizeSearch = R0 - HKCU\Software\Microsoft\Internet Explorer\Toolbar,LinksFolderName = R3 - URLSearchHook: (no name) - {7473b6bd-4691-4744-a82b-7854eb3d70b6} - (no file) O2 - BHO: Adobe PDF Reader Link Helper - {06849E9F-C8D7-4D59-B87D-784B7D6BE0B3} - C:\Program Files\Common Files\Adobe\Acrobat\ActiveX\AcroIEHelper.dll O2 - BHO: Babylon toolbar helper - {2EECD738-5844-4a99-B4B6-146BF802613B} - (no file) O2 - BHO: MrFroggy - {856E12B5-22D7-4E22-9ACA-EA9A008DD65B} - C:\Program Files\Minibar\Froggy.dll O2 - BHO: avast!

  • UIImage rounded corners

    - by catlan
    I try to get rounded corners on a UIImage, what I read so far, the easiest way is to use a mask images. For this I used code from TheElements iPhone Example and some image resize code I found. My problem is that resizedImage is always nil and I don't find the error... - (UIImage *)imageByScalingProportionallyToSize:(CGSize)targetSize { CGSize imageSize = [self size]; float width = imageSize.width; float height = imageSize.height; // scaleFactor will be the fraction that we'll // use to adjust the size. For example, if we shrink // an image by half, scaleFactor will be 0.5. the // scaledWidth and scaledHeight will be the original, // multiplied by the scaleFactor. // // IMPORTANT: the "targetHeight" is the size of the space // we're drawing into. The "scaledHeight" is the height that // the image actually is drawn at, once we take into // account the ideal of maintaining proportions float scaleFactor = 0.0; float scaledWidth = targetSize.width; float scaledHeight = targetSize.height; CGPoint thumbnailPoint = CGPointMake(0,0); // since not all images are square, we want to scale // proportionately. To do this, we find the longest // edge and use that as a guide. if ( CGSizeEqualToSize(imageSize, targetSize) == NO ) { // use the longeset edge as a guide. if the // image is wider than tall, we'll figure out // the scale factor by dividing it by the // intended width. Otherwise, we'll use the // height. float widthFactor = targetSize.width / width; float heightFactor = targetSize.height / height; if ( widthFactor < heightFactor ) scaleFactor = widthFactor; else scaleFactor = heightFactor; // ex: 500 * 0.5 = 250 (newWidth) scaledWidth = width * scaleFactor; scaledHeight = height * scaleFactor; // center the thumbnail in the frame. if // wider than tall, we need to adjust the // vertical drawing point (y axis) if ( widthFactor < heightFactor ) thumbnailPoint.y = (targetSize.height - scaledHeight) * 0.5; else if ( widthFactor > heightFactor ) thumbnailPoint.x = (targetSize.width - scaledWidth) * 0.5; } CGContextRef mainViewContentContext; CGColorSpaceRef colorSpace; colorSpace = CGColorSpaceCreateDeviceRGB(); // create a bitmap graphics context the size of the image mainViewContentContext = CGBitmapContextCreate (NULL, targetSize.width, targetSize.height, 8, 0, colorSpace, kCGImageAlphaPremultipliedLast); // free the rgb colorspace CGColorSpaceRelease(colorSpace); if (mainViewContentContext==NULL) return NULL; //CGContextSetFillColorWithColor(mainViewContentContext, [[UIColor whiteColor] CGColor]); //CGContextFillRect(mainViewContentContext, CGRectMake(0, 0, targetSize.width, targetSize.height)); CGContextDrawImage(mainViewContentContext, CGRectMake(thumbnailPoint.x, thumbnailPoint.y, scaledWidth, scaledHeight), self.CGImage); // Create CGImageRef of the main view bitmap content, and then // release that bitmap context CGImageRef mainViewContentBitmapContext = CGBitmapContextCreateImage(mainViewContentContext); CGContextRelease(mainViewContentContext); CGImageRef maskImage = [[UIImage imageNamed:@"Mask.png"] CGImage]; CGImageRef resizedImage = CGImageCreateWithMask(mainViewContentBitmapContext, maskImage); CGImageRelease(mainViewContentBitmapContext); // convert the finished resized image to a UIImage UIImage *theImage = [UIImage imageWithCGImage:resizedImage]; // image is retained by the property setting above, so we can // release the original CGImageRelease(resizedImage); // return the image return theImage; }

  • How to set parameters of CGContextAddArcToPoint method using a slider

    - by Manish Sahni
    am making an app in which i have to control a smile of a face like graphics. For example if i slide the slider down(to a value less than middle) it should give the arc a sad face(like :-( ) effect and if i slide the slider up the arc should give the effect of smile(like :-) ).initially lips are like :-| . I need to control the lips which is an arc using a slider? smileSliderViewController.h #import <UIKit/UIKit.h> @interface smileSliderViewController : UIViewController { IBOutlet UISlider *slider; } -(IBAction)valueChange:(id)sender; @end smileSliderViewController.m #import "smileSliderViewController.h" //#import "smile.h" @implementation smileSliderViewController -(IBAction)valueChange:(id)sender { int value = (int)(slider.value); if(value>0 && value<25) { //value--; CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetLineWidth(context, 2.0); CGColorSpaceRef colorspace = CGColorSpaceCreateDeviceRGB(); CGFloat components[] = {0.0,0.0,1.0,1.0}; CGColorRef color = CGColorCreate(colorspace, components); CGContextSetStrokeColorWithColor(context, color); CGContextMoveToPoint(context, 120,180); CGContextAddArcToPoint(context, 190 , 170, 270, 200, 0 ); CGContextStrokePath(context); } } smile.h #import <UIKit/UIKit.h> #import "smile.m" @interface smile : UIView { IBOutlet UISlider *slider; } @end smile.m #import "smile.h" #import "smileSliderViewController.h" @implementation smile - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { // Initialization code } return self; } - (void)drawRect:(CGRect)rect { CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetLineWidth(context, 2.0); //CGContextSetStrokeColor(context, [UIColor redColor].CGColor); CGColorSpaceRef colorspace = CGColorSpaceCreateDeviceRGB(); CGFloat components[] = {0.0,0.0,1.0,1.0}; CGColorRef color = CGColorCreate(colorspace, components); CGContextSetStrokeColorWithColor(context, color); CGRect rectangle = CGRectMake(60, 20, 200,200); CGContextAddEllipseInRect(context, rectangle); CGContextStrokePath(context); /*CGRect rectangle1 = CGRectMake(130,170,50,10); CGContextAddRect(context,rectangle1); CGContextStrokePath(context);*/ /*CGContextMoveToPoint(context,100,200); CGContextAddArcToPoint(context,120,150,400,150,70 ); CGContextStrokePath(context);*/ /*CGContextMoveToPoint(context, 100,100); CGContextAddArcToPoint(context, -100,200, -400,200, 80); CGContextStrokePath(context);*/ CGContextSetStrokeColorWithColor(context,color); CGRect rectangle2 = CGRectMake(80, 90, 50, 8); CGContextAddEllipseInRect(context, rectangle2); CGContextStrokePath(context); CGContextSetStrokeColorWithColor(context,color); CGRect rectangle3 = CGRectMake(180, 90, 50, 8); CGContextAddEllipseInRect(context, rectangle3); CGContextStrokePath(context); CGContextSetStrokeColorWithColor(context,color); CGContextMoveToPoint(context, 155,120); CGContextAddLineToPoint(context, 155,160); CGContextStrokePath(context); /*CGContextSetStrokeColorWithColor(context, color); CGRect rectangle4 = CGRectMake(130, 180, 50,8); CGContextAddEllipseInRect(context, rectangle4); CGContextStrokePath(context);*/ /*CGContextSetStrokeColorWithColor(context,color); CGContextMoveToPoint(context, 120,180); CGContextAddLineToPoint(context, 190,180); CGContextStrokePath(context);*/ int value = (int)(slider.value); if(value == 25) { CGContextMoveToPoint(context, 120,180); CGContextAddArcToPoint(context, 190 , 180, 250 , 180, 0 ); CGContextStrokePath(context); } }

  • zoom a JPanel and all of its components

    - by user253530
    I have a big JPanel which holds many TileMapping objects (TileMapping extends JPanel). I want to zoom the big JPanel and all of its components to be scaled aswell. A TileMapping has an image which of course has to be zoomed as well. here is my TileMapping class public class TileMapping extends JPanel { private double zoom = 1.0; private Mapping mapping; private int height; private int width; private int xCoord; private int yCoord; TileMapping(Mapping m, int w, int h, int x, int y) { super(); mapping = m; height = h; width = w; this.xCoord = x; this.yCoord = y; this.setPreferredSize(new Dimension(w, h)); } public int getXcoord() { return xCoord; } public int getYcoord() { return yCoord; } public Mapping getMapping() { return mapping; } public void setMapping(Mapping m) { mapping = m; } public void originalSize() { zoom = 1; } public void zoomIn() { zoom += 0.2; } public void zoomOut() { zoom -= 0.2; } @Override public void paintComponent(Graphics g) { Graphics2D g2d = (Graphics2D) g; if (mapping.getImage() != null) { BufferedImage bg = mapping.getImage(); g2d.scale(zoom, zoom); g2d.drawImage(bg, 0, 0, width, height, this); } else { g2d.scale(zoom, zoom); this.setBackground(Color.white); } } } I need to know how i should continue this on the main JPanel which is populated using this code: This is part of a MapWindow class. if you carefully read the code you will understand what i'm talking about. Basically this is a Tile MapEditor and I am simulating a Tile as a JPanel which holds the mapping object (mapping is a binding between an ASCII character and an image) you place. private void populateMapPanel(Map map) { GridBagConstraints c = new GridBagConstraints(); mapPanel.setLayout(new GridBagLayout()); for (int i = 0; i < map.getMapGrid().getRows(); i++) { for (int j = 0; j < map.getMapGrid().getColumns(); j++) { tile = new TileMapping(map.getMapItem(i, j), cellSize, cellSize, i, j); tile.setBorder(new LineBorder(Color.black)); tile.addMouseListener(this); tile.addMouseMotionListener(this); c.gridx = i; c.gridy = j; mapPanel.add(tile, c); } } mapPanel.validate(); mapPanel.repaint(); } I need to know how to do the following: 1. When the user presses Zoom In the mapPanel should zoom in and also all the images in the smaller panels. 2. when the user click and drag over the TileMappings an image should be painted on them and this image should get scaled of course if the mapPanel is zoomed. Pseudo code, ideas, hints, java code ...anything would be helpful. Thank you

I get an empty array to my application's main method. Probably unrelated, my splash screen doesn't work :( Any pointers on getting this working?

  • How the JOptionPane works

    - by DevAno1
    How can I control what happens with window after clicking JOPtionPane buttons ? I'm trying to implement simple file chooser. In my frame I have 3 buttons (OK, Cancel, Browse). Browse button opens file search window, and after picking files should return to main frame. Clicking OK will open a frame with the content of the file. Now porblem looks this way. With the code below, I can choose file but directly after that a new frame is created, and my frame with buttons dissapears : import java.io.File; import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; import java.awt.*; import javax.swing.*; import java.io.*; public class Main { public static void main(String args[]) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { show("Window"); } }); } public static void show(String frame_name){ JFrame frame = new JFrame(frame_name); frame.setPreferredSize(new Dimension(450, 300)); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel top = new JPanel(); top.setLayout(new BoxLayout(top, BoxLayout.Y_AXIS)); JFileChooser fc = new JFileChooser(new File(".")); JPanel creator = new JPanel(); creator.setLayout(new BoxLayout(creator, BoxLayout.Y_AXIS)); creator.add(top); String[] buttons = {"OK", "Cancel", "Browse"}; int rc = JOptionPane.showOptionDialog( null, creator, frame_name, JOptionPane.DEFAULT_OPTION, JOptionPane.PLAIN_MESSAGE, null, buttons, buttons[0] ); String approveButt = ""; switch(rc){ case 0: break; case 1: break; case 2: approveButt = buttons[rc]; int retVal = fc.showDialog(null, approveButt); if (retVal == JFileChooser.APPROVE_OPTION) System.out.println(approveButt + " " + fc.getSelectedFile()); break; } frame.pack(); frame.setVisible(true); } } With the second code I can return to my menu, but in no way I am able to pop this new frame, which appeared with first code. How to control this ? What am I missing ? public class Main { public static void main(String args[]) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { show("Window"); } }); } public static void show(String frame_name){ JFrame frame = new JFrame(frame_name); frame.setPreferredSize(new Dimension(450, 300)); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel top = new JPanel(); top.setLayout(new BoxLayout(top, BoxLayout.Y_AXIS)); JFileChooser fc = new JFileChooser(new File(".")); JPanel creator = new JPanel(); creator.setLayout(new BoxLayout(creator, BoxLayout.Y_AXIS)); creator.add(top); String[] buttons = {"OK", "Cancel", "Browse"}; String approveButt = ""; Plane m = null; int rc = -1; while (rc != 0) { rc = JOptionPane.showOptionDialog( null, creator, frame_name, JOptionPane.DEFAULT_OPTION, JOptionPane.PLAIN_MESSAGE, null, buttons, buttons[0] ); switch (rc) { case 0: m = new Plane(); case 1: System.exit(0); case 2: approveButt = buttons[rc]; int retVal = fc.showDialog(null, approveButt); if (retVal == JFileChooser.APPROVE_OPTION) System.out.println(approveButt + " " + fc.getSelectedFile()); break; default: break; } } addComponents(frame.getContentPane(), m); frame.pack(); frame.setVisible(true); } private static void addComponents(Container c, Plane e) { c.setLayout(new BoxLayout(c, BoxLayout.Y_AXIS)); c.add(e); } } class Plane extends JPanel { public Plane(){ } @Override public void paint(Graphics g){ g.setColor(Color.BLUE); g.fillRect(0, 0, 400, 250); } }

  • KVM Virtual guest Paused on Reboot

    I'm running REHL 6 and just installed a Ubuntu Server Guest via KVM set to start at boot. This works correctly and the guest loads, but it loads "paused" and requires that I manually un-pause it.

  • Dispatcher Timer Problem

    - by will
    I am trying to make a game in silverlight that also has widgets in it. To do this I am using a dispatcher timer running a game loop that updates graphics etc. In this I have a variable that has to be accessed by both by the constantly running game loop and UI event code. At first look it seemed that the gameloop had its own local copy of currentUnit (the variable), despite the variable being declared globally. I am trying to update currentUnit with an event by the widget part of the app, but the timer's version of the variable is not being updated. What can I do get the currentUnit in the gameloop loop to be updated whenever I update currentUnit via a click event? Here is the code for setting currentUnit as part of a click event DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(Unit)); currentUnit = serializer.ReadObject(e.Result) as Unit; txtName.Text = currentUnit.name; Canvas.SetLeft(txtName, 100 - (int)Math.Ceiling(txtName.ActualWidth) / 2); txtX.Text = "" + currentUnit.x; txtY.Text = "" + currentUnit.y; txtX.Text = "" + currentUnit.owner; txtY.Text = "" + currentUnit.moved; txtName.Text = "" + currentUnit.GetHashCode(); And here is a snippet from the gameLoop loop //deal with phase changes and showing stuff if (txtPhase.Text == "Move" && movementPanel.Visibility == Visibility.Collapsed) { if (currentUnit != null) { if (currentUnit.owner) { if (currentUnit.moved) { txtMoved.Text = "This Unit has Already Moved!"; movementPanel.Visibility = Visibility.Collapsed; } else { txtMoved.Text = "" + currentUnit.GetHashCode(); movementPanel.Visibility = Visibility.Visible; } } else { txtMoved.Text = "bam"; movementPanel.Visibility = Visibility.Collapsed; } } else { txtMoved.Text = "slam"; movementPanel.Visibility = Visibility.Collapsed; } //loadUnitList(); } Here is the code for my unit class. using System; public class Unit { public int id { get; set; } public string name { get; set; } public string image { get; set; } public int x { get; set; } public int y { get; set; } public bool owner { get; set; } public int rotation { get; set; } public double movement { get; set; } public string type { get; set; } public bool moved { get; set; } public bool fired { get; set; } } Overall, any simple types, like a double is being 'updated' correctly, yet a complex of my own type (Unit) seems to be holding a local copy. Please help, I've asked other places and no one has had an answer for me!

  • java gui changing picture causes heapspace error

    - by pie154
    I have a java programme than when a button is clicked it updates the image on screen to the according image. this will work for the first 15 or so clicks then it causes a java heapspace error. I think it is because of the way I am updating the jpanel that contains the bufferedimage but not sure what the reason is. My code to get make the JPanel contain the new image is, public class extraScreenPanel { static JPanel screenPanel = new JPanel(new BorderLayout()); public static JPanel extraScreenPanel(int dispNum) { JLabel label = new JLabel("" + dispNum + ""); label.setPreferredSize(new Dimension(800, 600)); //label.setUI( new VerticalLabelUI(true) ); label.setVerticalAlignment( SwingConstants.TOP ); screenPanel = imgDisp(dispNum); label.setForeground(Color.white); label.setFont(new Font("Serif", Font.BOLD, 200)); screenPanel.add(label, BorderLayout.PAGE_END ); return screenPanel; } public static JPanel imgDisp(int picNum) { /* String url[] = new String[5000]; String part1; url[0] = "C:/PiPhotoPic/pic16.jpg"; for(Integer i=1;i<5000;i++){ if(i<10){part1 = "C:/temp/new0000000";} else if(i<100){part1 = "C:/temp/new000000";} else if(i<1000){part1 = "C:/temp/new00000";} else {part1 = "C:/temp/new00000";} String num = Integer.toString(i); url[i]= part1 + num + ".jpg"; } if(picNum<0){picNum=0;} String ref = url[picNum];*/ //this code is just to get specific ref for image location BufferedImage loadImg = loadImage(ref); JImagePanel panel = new JImagePanel(loadImg, 0, 0); panel.setPreferredSize(new Dimension(800, 600)); return panel; } public static class JImagePanel extends JPanel{ private BufferedImage image; int x, y; public JImagePanel(BufferedImage image, int x, int y) { super(); this.image = image; this.x = x; this.y = y; } @Override protected void paintComponent(Graphics g) { super.paintComponent(g); g.drawImage(image, x, y, null); } } public static BufferedImage loadImage(String ref) { BufferedImage bimg = null; try { bimg = javax.imageio.ImageIO.read(new File(ref)); } catch (Exception e) { e.printStackTrace(); } BufferedImage bimg2 = resize(bimg,800,600); return bimg2; } public static BufferedImage resize(BufferedImage img, int newW, int newH) { int w = img.getWidth(); int h = img.getHeight(); BufferedImage dimg = dimg = new BufferedImage(newW, newH, img.getType()); Graphics2D g = dimg.createGraphics(); g.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR); g.drawImage(img, 0, 0, newW, newH, 0, 0, w, h, null); g.dispose(); return dimg; } } And the code that updates my gui is, it works by removing the panel from its containg panel and then readding it to it. picPanel = imgDisp.imgDisp(num); repaintPicPanel(); public static void repaintPicPanel() { picPanel.removeAll(); menuPanel.remove(picPanel);; menuPanel.add(picPanel, BorderLayout.LINE_START); }

  • Sporadic disk clicking sound

    - by Abdó
    Hi, I'm having some unusual and sporadic hard disk clicking issues. Here is a cronological description of the facts. I'm using an ASUS P6T-SE with Intel Core i7, 6Gb RAM 600W Power supply and ATI4670 graphics, running Ubuntu 10.10. About one month ago my hard disk (SATA II Seagate Barracuda 1Tb 7200 rpm) started making a clicking sound: a sort of loud tic-tac, every second or so, when involved in disk activity. The system was clearly slower than before at disk access, but it was functional and I could not find any signal of trouble on the linux logs. I disconnected the disk and tried an older SATA drive I had around: no problem with it. Then I reconnected the Seagate disk, and the problem was mysteriously gone. Ubuntu booted normally, usual speed, no clicking. A couple of weeks later, the problem reappeared. I tried disconnecting reconnecting (as it somehow solved the problem before) without luck. So, despite it was a rather new drive, I assumed it was a hardware issue, made backups and bought a new drive. The new drive is a SATA II Seagate Barracuda 1.5 Tb 7200 rpm. I installed both drives at the same time, with the intention of transferring my files from on to the other. To my surprise, when I booted the computer with both drives, both started making the clicking sound !! Even worse, I removed the old drive, leaving the unformated new drive connected, and booted from a LiveCD. It kept clicking ! Puzzled by this, I tried both drives on my laptop with a SATA to USB cable. At the moment I connected any of them, they made one or two unusual clicks and immediately stopped doing that and worked normally. The old drive I thought almost dead, was working like a charm as if nothing happened. Then I thought: "ok, it must be the motherboard. Let's try again". So, I reconnected the old drive to the ASUS P6T motherboard (the same cables and SATA port as before), and it worked as if nothing happened ! The problem was gone again. The new 1.5 Tb drive was also working ok: No clicking nor slowdown. So I left the old 1Tb disk connected and kept using the computer daily during 3 weeks, until today it happened again. Now I don't really know what to do or check. I'm not even sure if it is a hardware issue any more ! This is rather annoying as it seems it happens with a period of 2 or 3 weeks and I have no means of forcing it to happen. Does anyone have a clue of what can causes this behaviour or have any suggestions of things I should check when it happens again ? What I did today is checking some SMART parameters Error log: smartctl -l error /dev/sda. No errors Short selftest: smartctl -t short /dev/sda. No errors Disk Health check: smartctl -H /dev/sda. passed And here are the vendor specific parameters (smartctl -A /dev/sda) Which I'm not quite sure how to interpret. === START OF READ SMART DATA SECTION === SMART Attributes Data Structure revision number: 10 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x000f 120 099 006 Pre-fail Always - 235962588 3 Spin_Up_Time 0x0003 095 095 000 Pre-fail Always - 0 4 Start_Stop_Count 0x0032 100 100 020 Old_age Always - 187 5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always - 0 7 Seek_Error_Rate 0x000f 072 060 030 Pre-fail Always - 16348045 9 Power_On_Hours 0x0032 096 096 000 Old_age Always - 3590 10 Spin_Retry_Count 0x0013 100 100 097 Pre-fail Always - 0 12 Power_Cycle_Count 0x0032 100 100 020 Old_age Always - 94 183 Runtime_Bad_Block 0x0032 100 100 000 Old_age Always - 0 184 End-to-End_Error 0x0032 100 100 099 Old_age Always - 0 187 Reported_Uncorrect 0x0032 100 100 000 Old_age Always - 0 188 Command_Timeout 0x0032 100 097 000 Old_age Always - 4295164029 189 High_Fly_Writes 0x003a 100 100 000 Old_age Always - 0 190 Airflow_Temperature_Cel 0x0022 070 057 045 Old_age Always - 30 (Lifetime Min/Max 19/31) 194 Temperature_Celsius 0x0022 030 043 000 Old_age Always - 30 (0 18 0 0) 195 Hardware_ECC_Recovered 0x001a 037 026 000 Old_age Always - 235962588 197 Current_Pending_Sector 0x0012 100 100 000 Old_age Always - 0 198 Offline_Uncorrectable 0x0010 100 100 000 Old_age Offline - 0 199 UDMA_CRC_Error_Count 0x003e 200 200 000 Old_age Always - 0 240 Head_Flying_Hours 0x0000 100 253 000 Old_age Offline - 73950746906346 241 Total_LBAs_Written 0x0000 100 253 000 Old_age Offline - 1832967731 242 Total_LBAs_Read 0x0000 100 253 000 Old_age Offline - 3294986902 Any clue to this mystery will be really welcome.

  • Android Alert Dialog Extract User Choice Radio Button?

    - by kel196
    Apologies for any coding ignorance, I am a beginner and am still learning! I am creating a quiz app which reads questions off a SQL database and plots them as points on a google map. As the user clicks each point, an alert dialog appears with radio buttons to answer some question. My radiobuttons are in CustomItemizedOverlay file and when I click submit, I want to be able to send the user choice back to the database, save it and return to the user if their answer is correct. My question is this, how do I pass the user choice out once the submit button has been clicked? I tried making a global variable to read what was selected to no avail. Any suggestions would be appreciated! If I need to post any other code, please ask and I will do so ASAP! package uk.ac.ucl.cege.cegeg077.uceskkw; import java.util.ArrayList; import android.app.AlertDialog; import android.content.Context; import android.content.DialogInterface; import android.graphics.drawable.Drawable; import android.widget.Toast; import com.google.android.maps.ItemizedOverlay; import com.google.android.maps.OverlayItem; public class CustomItemizedOverlay2 extends ItemizedOverlay<OverlayItem> { private ArrayList<OverlayItem> mapOverlays = new ArrayList<OverlayItem>(); private Context context; public CustomItemizedOverlay2(Drawable defaultMarker) { super(boundCenterBottom(defaultMarker)); } public CustomItemizedOverlay2(Drawable defaultMarker, Context context) { this(defaultMarker); this.context = context; } @Override protected OverlayItem createItem(int i) { return mapOverlays.get(i); } @Override public int size() { return mapOverlays.size(); } @Override protected boolean onTap(int index) { OverlayItem item = mapOverlays.get(index); // gets the snippet from ParseKMLAndDisplayOnMap and splits it back into // a string. final CharSequence allanswers[] = item.getSnippet().split("::"); AlertDialog.Builder dialog = new AlertDialog.Builder(context); dialog.setIcon(R.drawable.easterbunnyegg); dialog.setTitle(item.getTitle()); dialog.setSingleChoiceItems(allanswers, -1, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int whichButton) { Toast.makeText(context, "You have selected " + allanswers[whichButton], Toast.LENGTH_SHORT).show(); } }); dialog.setPositiveButton(R.string.button_submit, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int whichButton) { dialog.dismiss(); // int selectedPosition = ((AlertDialog) // dialog).getListView().getCheckedItemPosition(); Toast.makeText(context, "hi!", Toast.LENGTH_SHORT) .show(); } }); dialog.setNegativeButton(R.string.button_close, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int whichButton) { dialog.dismiss(); // on cancel button action } }); AlertDialog question = dialog.create(); question.show(); return true; } public void addOverlay(OverlayItem overlay) { mapOverlays.add(overlay); this.populate(); } }

  • SurfaceView drawn on top of other elements after coming back from specific activity

    - by spirytus
    I have an activity with video preview displayed via SurfaceView and other views positioned over it. The problem is when user navigates to Settings activity (code below) and comes back then the surfaceview is drawn on top of everything else. This does not happen when user goes to another activity I have, neither when user navigates outside of app eg. to task manager. Now, you see in code below that I have setContentVIew() call wrapped in conditionals so it is not called every time when onStart() is executed. If its not wrapped in if statements then all works fine, but its causing loosing lots of memory (5MB+) each time onStart() is called. I tried various combinations and nothing seems to work so any help would be much appreciated. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //Toast.makeText(this,"Create ", 2000).show(); // set 32 bit window (draw correctly transparent images) getWindow().getAttributes().format = android.graphics.PixelFormat.RGBA_8888; // set the layout of the screen based on preferences of the user sharedPref = PreferenceManager.getDefaultSharedPreferences(this); } public void onStart() { super.onStart(); String syncConnPref = null; syncConnPref = sharedPref.getString("screensLayouts", "default"); if(syncConnPref.contentEquals("default") && currentlLayout!="default") { setContentView(R.layout.fight_recorder_default); } else if(syncConnPref.contentEquals("simple") && currentlLayout!="simple") { setContentView(R.layout.fight_recorder_simple); } // I I uncomment line below so it will be called every time without conditionals above, it works fine but every time onStart() is called I'm losing 5+ MB memory (memory leak?). The preview however shows under the other elements exactly as I need memory leak makes it unusable after few times though // setContentView(R.layout.fight_recorder_default); if(getCamera()==null) { Toast.makeText(this,"Sorry, camera is not available and fight recording will not be permanently stored",2000).show(); // TODO also in here put some code replacing the background with something nice return; } // now we have camera ready and we need surface to display picture from camera on so // we instantiate CameraPreviw object which is simply surfaceView containing holder object. // holder object is the surface where the image will be drawn onto // this is where camera live cameraPreview will be displayed cameraPreviewLayout = (FrameLayout) findViewById(id.camera_preview); cameraPreview = new CameraPreview(this); // now we add surface view to layout cameraPreviewLayout.removeAllViews(); cameraPreviewLayout.addView(cameraPreview); // get layouts prepared for different elements (views) // this is whole recording screen, as big as screen available recordingScreenLayout=(FrameLayout) findViewById(R.id.recording_screen); // this is used to display sores as they are added, it displays like a path // each score added is a new text view simply and as user undos these are removed one by one allScoresLayout=(LinearLayout) findViewById(R.id.all_scores); // layout prepared for controls like record/stop buttons etc startStopLayout=(RelativeLayout) findViewById(R.id.start_stop_layout); // set up timer so it can be turned on when needed //fightTimer=new FightTimer(this); fightTimer = (FightTimer) findViewById(id.fight_timer); // get views for displaying scores score1=(TextView) findViewById(id.score1); score2=(TextView) findViewById(id.score2); advantages1=(TextView) findViewById(id.advantages1); advantages2=(TextView) findViewById(id.advantages2); penalties1=(TextView) findViewById(id.penalties1); penalties2=(TextView) findViewById(id.penalties2); RelativeLayout welcomeScreen=(RelativeLayout) findViewById(id.welcome_screen); Animation fadeIn = AnimationUtils.loadAnimation(this, R.anim.fade_in); welcomeScreen.startAnimation(fadeIn); Toast.makeText(this,"Start ", 2000).show(); animateViews(); } Settings activity is below, after coming back from this activity surfaceview is drawn on top of other elements. public class SettingsActivity extends PreferenceActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); if(MyFirstAppActivity.getCamera()==null) { Toast.makeText(this,"Sorry, camera is not available",2000).show(); return; } addPreferencesFromResource(R.xml.preferences); } }

  • Why don't I just build the whole web app in Javascript and Javascript HTML Templates?

    - by viatropos
    I'm getting to the point on an app where I need to start caching things, and it got me thinking... In some parts of the app, I render table rows (jqGrid, slickgrid, etc.) or fancy div rows (like in the New Twitter) by grabbing pure JSON and running it through something like Mustache, jquery.tmpl, etc. In other parts of the app, I just render the info in pure HTML (server-side HAML templates), and if there's searching/paginating, I just go to a new URL and load a new HTML page. Now the problem is in caching and maintainability. On one hand I'm thinking, if everything was built using Javascript HTML Templates, then my app would serve just an HTML layout/shell, and a bunch of JSON. If you look at the Facebook and Twitter HTML source, that's basically what they're doing (95% json/javascript, 5% html). This would make it so my app only needed to cache JSON (pages, actions, and/or records). Which means you'd hit the cache no matter if you were some remote api developer accessing a JSON api, or the strait web app. That is, I don't need 2 caches, one for the JSON, one for the HTML. That seems like it'd cut my cache store down in half, and streamline things a little bit. On the other hand, I'm thinking, from what I've seen/experienced, generating static HTML server-side, and caching that, seems to be much better performance wise cross-browser; you get the graphics instantly and don't have to wait that split-second for javascript to render it. StackOverflow seems to do everything in plain HTML, and you can tell... everything appears at once. Notice how though on twitter.com, the page is blank for .5-1 seconds, and the page chunks in: the javascript has to render the json. The downside with this is that, for anything dynamic (like endless scrolling, or grids), I'd have to create javascript templates anyway... so now I have server-side HAML templates, client-side javascript templates, and a lot more to cache. My question is, is there any consensus on how to approach this? What are the benefits and drawbacks from your experience of mixing the two versus going 100% with one over the other? Update: Some reasons that factor into why I haven't yet made the decision to go with 100% javascript templating are: Performance. Haven't formally tested, but from what I've seen, raw html renders faster and more fluidly than javascript-generated html cross-browser. Plus, I'm not sure how mobile devices handle dynamic html performance-wise. Testing. I have a lot of integration tests that work well with static HTML, so switching to javascript-only would require 1) more focused pure-javascript testing (jasmine), and 2) integrating javascript into capybara integration tests. This is just a matter of time and work, but it's probably significant. Maintenance. Getting rid of HAML. I love HAML, it's so easy to write, it prints pretty HTML... It makes code clean, it makes maintenance easy. Going with javascript, there's nothing as concise. SEO. I know google handles the ajax /#!/path, but haven't grasped how this will affect other search engines and how older browsers handle it. Seems like it'd require a significant setup.

  • How to add addtional disks to a Windows 2008 KVM based Guest?

    - by taazaa
    I have a Win 2008 KVM based guest VM running on a Ubuntu 10 host. It is a raw image of 22G. I want to add a "data" drive which would show up as "D:\" drive on the guest. I first created a raw image using: qemu-img create -f raw ~/vmdisk2.img 50G Then, tried attaching it using virsh attach-disk. When that did not work, I tried editing the xml file of the VM directly. Both did not seem to work. I would greatly appreciate any help on how to do this and what the best practice is. I want to keep the base image small, so that I can clone it (hopefully) and then attach necessary storage based on the application at hand. Update: The xml of the vm before adding the second drive: <domain type='kvm'> <name>win08e-vm1</name> <uuid>183a4ba0-1c0b-0b04-ad01-aa7c3a4cb390</uuid> <memory>1048576</memory> <currentMemory>1048576</currentMemory> <vcpu>2</vcpu> <os> <type arch='x86_64' machine='pc-0.12'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset='localtime'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/var/lib/libvirt/images/win08e-vm1.img'/> <target dev='hda' bus='ide'/> <address type='drive' controller='0' bus='0' unit='0'/> </disk> <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/home/taazaa/iso/Win08ER264.iso'/> <target dev='hdc' bus='ide'/> <readonly/> <address type='drive' controller='0' bus='1' unit='0'/> </disk> <controller type='ide' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> </controller> <interface type='bridge'> <mac address='52:54:00:7f:a7:ae'/> <source bridge='br0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target type='serial' port='0'/> </console> <input type='tablet' bus='usb'/> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/> <video> <model type='vga' vram='9216' heads='1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> <memballoon model='virtio'> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </memballoon> </devices> </domain> Thanks!

  • Problems with createImage(int width, int height)

    - by Jonathan
    I have the following code, which is run every 10ms as part of a game: private void gameRender() { if(dbImage == null) { //createImage() returns null if GraphicsEnvironment.isHeadless() //returns true. (java.awt.GraphicsEnvironment) dbImage = createImage(PWIDTH, PHEIGHT); if(dbImage == null) { System.out.println("dbImage is null"); //Error recieved return; } else dbg = dbImage.getGraphics(); } //clear the background dbg.setColor(Color.white); dbg.fillRect(0, 0, PWIDTH, PHEIGHT); //draw game elements... if(gameOver) { gameOverMessage(dbg); } } The problem is that it enters the if statement which checks for the Image being null, even after I attempt to define the image. I looked around, and it seems that createImage() will return null if GraphicsEnvironment.isHeadless() returns true. I don't understand exactly what the isHeadless() method's purpose is, but I thought it might have something to do with the compiler or IDE, so I tried on two, both of which get the same error (Eclipse, and BlueJ). Anyone have any idea what the source of the error is, and how I might fix it? Thanks in advance Jonathan ................................................................... EDIT: I am using java.awt.Component.createImage(int width, int height). The purpose of this method is to ensure the creation of, and edit an Image that will contain the view of the player of the game, that will later be drawn to the screen by means of a JPanel. Here is some more code if this helps at all: public class Sim2D extends JPanel implements Runnable { private static final int PWIDTH = 500; private static final int PHEIGHT = 400; private volatile boolean running = true; private volatile boolean gameOver = false; private Thread animator; //gameRender() private Graphics dbg; private Image dbImage = null; public Sim2D() { setBackground(Color.white); setPreferredSize(new Dimension(PWIDTH, PHEIGHT)); setFocusable(true); requestFocus(); //Sim2D now recieves key events readyForTermination(); addMouseListener( new MouseAdapter() { public void mousePressed(MouseEvent e) { testPress(e.getX(), e.getY()); } }); } //end of constructor private void testPress(int x, int y) { if(!gameOver) { gameOver = true; //end game at mousepress } } //end of testPress() private void readyForTermination() { addKeyListener( new KeyAdapter() { public void keyPressed(KeyEvent e) { int keyCode = e.getKeyCode(); if((keyCode == KeyEvent.VK_ESCAPE) || (keyCode == KeyEvent.VK_Q) || (keyCode == KeyEvent.VK_END) || ((keyCode == KeyEvent.VK_C) && e.isControlDown()) ) { running = false; //end process on above list of keypresses } } }); } //end of readyForTermination() public void addNotify() { super.addNotify(); //creates the peer startGame(); //start the thread } //end of addNotify() public void startGame() { if(animator == null || !running) { animator = new Thread(this); animator.start(); } } //end of startGame() //run method for world public void run() { while(running) { long beforeTime, timeDiff, sleepTime; beforeTime = System.nanoTime(); gameUpdate(); //updates objects in game (step event in game) gameRender(); //renders image paintScreen(); //paints rendered image to screen timeDiff = (System.nanoTime() - beforeTime) / 1000000; sleepTime = 10 - timeDiff; if(sleepTime <= 0) //if took longer than 10ms { sleepTime = 5; //sleep a bit anyways } try{ Thread.sleep(sleepTime); //sleep by allotted time (attempts to keep this loop to about 10ms) } catch(InterruptedException ex){} beforeTime = System.nanoTime(); } System.exit(0); } //end of run() private void gameRender() { if(dbImage == null) { dbImage = createImage(PWIDTH, PHEIGHT); if(dbImage == null) { System.out.println("dbImage is null"); return; } else dbg = dbImage.getGraphics(); } //clear the background dbg.setColor(Color.white); dbg.fillRect(0, 0, PWIDTH, PHEIGHT); //draw game elements... if(gameOver) { gameOverMessage(dbg); } } //end of gameRender() } //end of class Sim2D Hope this helps clear things up a bit, Jonathan

  • Lines don't overlap when they should Java Swing

    - by Sven
    I'm drawing lines in a JFrame on a self made gridPanel. Problem is, I draw the lines between 2 points. When I have a line that is between point 1 and point 2 and a line between point 2 and point 3, the lines should connect. This however isn,t the case, there is a small gap in between, no idea why. But it isn't drawing till the end of the specified point. (start point is correct.) Here is the code of the JFrame: public void initialize(){ this.setLayout(new BorderLayout()); this.setPreferredSize(new Dimension(500, 400)); gridPane = new GridPane(); gridPane.setBackground(Color.WHITE); gridPane.setSize(this.getPreferredSize()); gridPane.setLocation(0, 0); this.add(gridPane,BorderLayout.CENTER); //createSampleLabyrinth(); drawWall(0,5,40,5); //These are the 2 lines that don't connect. drawWall(40,5,80,5); this.pack(); } drawWall calls a method that calls a method in GridPane. The relevant code in gridPane: /** * Draws a wall on this pane. With the starting point being x1, y1 and its end x2,y2. * @param x1 * @param y1 * @param x2 * @param y2 */ public void drawWall(int x1, int y1, int x2, int y2) { Wall wall = new Wall(x1,y1,x2,y2, true); wall.drawGraphic(); wall.setLocation(x1, y1); wall.setSize(10000,10000); this.add(wall, JLayeredPane.DEFAULT_LAYER); this.repaint(); } This method creates a wall and puts it in the Jframe. The relevant code of the wall: public class Wall extends JPanel { private int x1; private int x2; private int y1; private int y2; private boolean black; /** * x1,y1 is the start point of the wall (line) end is x2,y2 * * @param x1 * @param y1 * @param x2 * @param y2 */ public Wall(int x1, int y1, int x2, int y2, boolean black) { this.x1 = x1; this.x2 = x2; this.y1 = y1; this.y2 = y2; this.black = black; setOpaque(false); } private static final long serialVersionUID = 1L; public void drawGraphic() { repaint(); } public void paintComponent(Graphics g) { super.paintComponent(g); Graphics2D g2 = (Graphics2D) g; if(black){ g2.setColor(Color.BLACK); g2.setStroke(new BasicStroke(8)); } else { g2.setColor(Color.YELLOW); g2.setStroke(new BasicStroke(3)); } g2.drawLine(x1, y1, x2, y2); } } So, where am I going wrong? The true/false is to determine if the wall should be black or yellow, nothing to be concerned about.
