  • Creating a new window that stays on top even when in full screen mode (Qt on Linux)

    - by Lorenz03Tx
    I'm using Qt 4.6.3, and ubuntu linux on an embedded target. I call dlg->setWindowState(Qt::WindowFullScreen); on my windows in my application (so I don't loose any real-estate on the touch screen to task bar and status panel on the top and bottom of the screen. This all works fine and as expected. The issue comes in when I want to popup the on screen keyboard to allow the user to input some data. I use m_keyProc= new QProcess(); m_keyProc->start("onboard -s 640x120"); This pops up the keyboard but it is behind the full screen window. The onbaord keyboards preferences are set such that it is always on top, but that seems to actually mean "except for full screen windows". I guess that makes sense and probably meets most use cases, but I need it to be really on top. Can I either A) Not be full screen mode (so the keyboard works) and programmatically hide the task bars? or B) Force the keyboard to be on top despite my full screen status? Note: On windows we call m_keyProc->start("C:\\Windows\\system32\\osk.exe"); and the osk keyboard is on top despite the full screen status. So, I'm guessing this is a difference in window mangers on the different operating systems. So do I need to set some flag on the window with the linux window manager?

  • Scroll the entire page with with UITableView that doesn't take up the entire screen

    - by KJF
    The only UITableViews I have worked with thus far are sized to fill the entire page. I'm trying to create a page in my app where I will have an image and a label on the top of the page followed by a UITableView to hold comments below it. Something like this springs to mind: http://www.inquisitr.com/wp-content/fbb.jpg My problem is if I add a UITableView below the image and label, when I scroll the tableview then only the UITableView cells scroll. Not the entire page. How would I go about making the entire page scroll so that the label and image scroll off the page and more table cells appear? Thanks.

  • Flex: cannot resize player back from Full Screen

    - by Patrick
    hi, The key event is not listened by my Flex app. Since it is really simple code, I cannot understand where the problem is... init() { stage.addEventListener(KeyboardEvent.KEY_DOWN, escHandler); } private function escHandler(event:KeyboardEvent):void { debugF.text = "ESC pressed"; } thanks

  • how to make the android app load faster?

    - by Tapan Desai
    I have designed an application for android, in which i am showing a splash screen before the main activity is started but the application takes 5-7 seconds to start on low-end devices. I want to reduce that time to as low as possible. I have been trying to reduce the things to be done in onCreate() but now i cannot remove any thing more from that. I am pasting the code that i have used to show the splash and the code from MainActivity. Please help me in reducing the startup time of the application. Splash.java @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.activity_splash); txtLoad = (TextView) findViewById(R.id.txtLoading); txtLoad.setText("v1.0"); new Thread() { public void run() { try { sleep(1000); } catch (InterruptedException e) { e.printStackTrace(); } finally { finish(); Intent intent = new Intent(SplashActivity.this,MainActivity.class); startActivity(intent); } } }.start(); } MainActivity.java @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.activity_main); editType1UserName = (EditText) findViewById(R.id.editTextType1UserName); editType1Password = (EditText) findViewById(R.id.editTextType1Password); editType2UserName = (EditText) findViewById(R.id.editTextType2UserName); editType2Password = (EditText) findViewById(R.id.editTextType2Password); editType3UserName = (EditText) findViewById(R.id.editTextType3UserName); editType3Password = (EditText) findViewById(R.id.editTextType3Password); editType4UserName = (EditText) findViewById(R.id.editTextType4UserName); editType4Password = (EditText) findViewById(R.id.editTextType4Password); mTxtPhoneNo = (AutoCompleteTextView) findViewById(R.id.mmWhoNo); mTxtPhoneNo.setThreshold(1); editText = (EditText) findViewById(R.id.editTextMessage); spinner1 = (Spinner) findViewById(R.id.spinnerGateway); btnsend = (Button) findViewById(R.id.btnSend); btnContact = (Button) findViewById(R.id.btnContact); btnsend.setOnClickListener((OnClickListener) this); btnContact.setOnClickListener((OnClickListener) this); mPeopleList = new ArrayList<Map<String, String>>(); PopulatePeopleList(); mAdapter = new SimpleAdapter(this, mPeopleList, R.layout.custcontview, new String[] { "Name", "Phone", "Type" }, new int[] { R.id.ccontName, R.id.ccontNo, R.id.ccontType }); mTxtPhoneNo.setAdapter(mAdapter); mTxtPhoneNo.setOnItemClickListener((OnItemClickListener) this); readPerson(); Panel panel; topPanel = panel = (Panel) findViewById(R.id.mytopPanel); panel.setOnPanelListener((OnPanelListener) this); panel.setInterpolator(new BounceInterpolator(Type.OUT)); getLoginDetails(); }

  • How can I find the right UV coordinates for interpolating a bezier curve?

    - by ssb
    I'll let this picture do the talking. I'm trying to create a mesh from a bezier curve and then add a texture to it. The problem here is that the interpolation points along the curve do not increase linearly, so points farther from the control point (near the endpoints) stretch and those in the bend contract, causing the texture to be uneven across the curve, which can be problematic when using a pattern like stripes on a road. How can I determine how far along the curve the vertices actually are so I can give a proper UV coordinate? EDIT: Allow me to clarify that I'm not talking about the trapezoidal distortion of the roads. That I know is normal and I'm not concerned about. I've updated the image to show more clearly where my concerns are. Interpolating over the curve I get 10 segments, but each of these 10 segments is not spaced at an equal point along the curve, so I have to account for this in assigning UV data to vertices or else the road texture will stretch/shrink depending on how far apart vertices are at that particular part of the curve.

  • Disable alt + tab moving windows by itself

    - by Lie Ryan
    Whenever I press Alt + Tab , Unity moves the window I'm switching to so that the whole window is inside the screen. This behavior is excruciatingly annoying because I often move a window (usually text editors) partially outside the current screen so I can view another window below it (usually a browser). Every time I Alt + Tab back to the text editor, I'm getting an unnecessary virtual screen switch, and Unity is rearranging the windows behind my back. For instance, here is a browser and text editor on Virtual Screen 1 (top left), note that the text editor is partially outside the current screen: Then I Alt-Tab to the browser (or clicked on it): Next, I Alt + Tab again to get back to the text editor, but Alt-Tab switched me to Virtual Screen 4 (bottom right) because a larger percentage of the text editor window is on virtual screen 4 than in virtual screen 1; and the browser is no longer in the screen. Also note that the text editor window moves from being on the bottom-right to the top-left, which is very disorienting as I can no longer keep track of where any of my windows are since they all keep moving around by themselves.. How do I disable this behavior? I don't want to have any virtual screen switch when Alt + Tab , especially since Alt + Tab does not list windows that is completely not in the current virtual screen anyway.

  • UV Atlas Generation and Seam Removal

    - by P. Avery
    I'm generating light maps for scene mesh objects using DirectX's UV Atlas Tool( D3DXUVAtlasCreate() ). I've succeeded in generating an atlas, however, when I try to render the mesh object using the atlas the seams are visible on the mesh. Below are images of a lightmap generated for a cube. Here is the code I use to generate a uv atlas for a cube: struct sVertexPosNormTex { D3DXVECTOR3 vPos, vNorm; D3DXVECTOR2 vUV; sVertexPosNormTex(){} sVertexPosNormTex( D3DXVECTOR3 v, D3DXVECTOR3 n, D3DXVECTOR2 uv ) { vPos = v; vNorm = n; vUV = uv; } ~sVertexPosNormTex() { } }; // create a light map texture to fill programatically hr = D3DXCreateTexture( pd3dDevice, 128, 128, 1, 0, D3DFMT_A8R8G8B8, D3DPOOL_MANAGED, &pLightmap );

float fU = ( f11 * f02 - f01 * f12 ) * invDenom; float fV = ( f00 * f12 - f01 * f02 ) * invDenom; // Check if point is in triangle if( ( fU >= 0 ) && ( fV >= 0 ) && ( fU + fV < 1 ) ) return true; return false; } Screenshot Lightmap I believe the problem comes from the difference between the lightmap uv coordinates and the pixel center coordinates...for example, here are the lightmap uv coordinates( generated by D3DXUVAtlasCreate() ) for a specific face( tri ) within the mesh, keep in mind that I'm using the mesh uv coordinates to write the pixels for the texture: v[ 0 ].uv = D3DXVECTOR2( 0.003581, 0.295631 ); v[ 1 ].uv = D3DXVECTOR2( 0.003581, 0.003581 ); v[ 2 ].uv = D3DXVECTOR2( 0.295631, 0.003581 ); the lightmap texture size is 128 x 128 pixels. The upper-left pixel center coordinates are: float halfPixel = 0.5 / 128 = 0.00390625; D3DXVECTOR2 pixelCenter = D3DXVECTOR2( halfPixel, halfPixel ); will the mapping and sampling of the lightmap texture will require that an offset be taken into account or that the uv coordinates are snapped to the pixel centers..? ...Any ideas on the best way to approach this situation would be appreciated...What are the common practices?

  • 13.10 Saucy login issues; black screen, loop, and freeze

    - by user135598
    Once upgraded to I 13.10 I was not able to get past the login screen. I had the black screen. Also; I can not log on with low graphics mode from recovery either. It makes no difference if I try default graphics driver or not. Then after running sudo install -f from recovery root prompt I got a login loop. I have purged fglrx, fglrx-legacy, and nvidia-current. I updated my repository with xorg-edgers and reinstalled nvidia-current. Now it semi-freezes at the login screen when I try to log on as my normal user. I say 'semi' because I can still use my mouse to click on the upper right hand Ubuntu logo and Shut Down or Restart the PC. I still cannot log on with my user name, but I can through the Guest login. While logged in as Guest I added a new user account with administrative privileges. I CAN log into this account without problem and from here am able to see that my .dmrc file in my original account reads: [Desktop] Session=XBMC I have changed 'Session=XBMC' to 'Session=ubuntu' and rebooted, but to no avail. The file resets itself and makes a backup of my changes. Any help would be greatly appreciated.

  • Ubuntu 12.04 login screen flickers. “Could not write bytes: broken pipes”

    - by Brayn
    I use Ubuntu 12.04 x64 with a dual-boot setup. Yesterday it worked fine but this morning when I attempted to boot it gets to the login screen and then it just flickers, alternating between the login screen and the console showing boot items (mainly Apache, the last one being "Battery status" although it's a desktop) all with [OK] status. The only error that I can see is: "Could not write bytes: broken pipes" on top of the screen. The only things I can think of that could cause this are: This morning I had a removable hdd plugged in during boot time, which I usually don't have Yesterday I've installed Dwarven Fortress that requires some x32 libraries so I've installed ia32 using synaptic. As far as I know this shouldn't brake the system but I didn't reboot yesterday so I can't be sure. I've tried booting in recovery mode and tried running the utils there but still no luck. I've ran out of ideas. Thanks. EDIT: Forgot to mention that all partitions have plenty of free space EDIT2: In the end I just reinstalled Ubuntu as time was of the essence.

  • When can a freely moving sphere escape from a ‘cage’ defined by a set of impassible coordinates?

    - by RGrey
    Hopefully there are some computational geometry folks here who can help me out with the following problem - Please imagine that I take a freely moving ball in 3-space and create a 'cage' around it by defining a set of impassible coordinates, Sc (i.e. points in 3-space that no part of the diffusing ball is allowed to overlap). These points reside within the volume, V(cage), of some larger sphere, where V(cage) V(ball). Provided the set of impassible coordinates, Sc, is there a computationally efficient and/or nice way to determine if the ball can ever escape the cage?

  • Codeigniter Image Library Cropping an Image with 2 sets of coordinates to make square anywhere?

    - by chris
    Spending time reading through the docs, and searching for examples. I understand cropping an image from top 0, and left 0 is pretty straight forward. However. I would like to pass 2 sets of coordinates, a starting point and an ending point. Four Points, a Square that is defined anywhere. However from the examples I am finding, and from what I gather the rendition is not going to let me do this. codeigniter so I am seeking confirmation on this thought, is it true that I can only provide end points from 0, and it crops a square based on said end points or can I actually specify an x start, an x end, and similar for y? Or is there some other technique I can use within codeigniter that will allow me to pass for coordinates for starting and ending points?

  • Is there a ways to make google store coordinates in the android map?

    - by Pavel
    Hi. I'm in the middle of developing android app using google map. My question is - how to store coordinates with google map and display them later on? I know how to use canvas, how to draw it etc. but I want to store those coordinates with google map - just like with the google maps feature on internet. When I log in I can see points I've put on the map straight away. Can someone please tell me how to do that? There must be a way. Any answers greatly appreciated!

  • SQL SERVER – Manage Help Settings – CTRL + ALT + F1

    - by pinaldave
    It is a miracle that curiosity survives formal education. ~ Albert Einstein I have 3 years old daughter and she never misses any chance to play with the system. I have multiple computers and I always make sure that if I am working with production server, I never leave it open but when I am doing some experiment I often leave my computer open. My daughter loves the part when I have left the computer open and I am not observing her. Recently I had the same scenario, I got urgent call and I moved away from my computer and when I returned she was playing with SSMS left open my computer. Here is the screen which was visible on the screen. For a moment, I could not figure out what was this screen and what was about to get updated. I tried to ask her what keys she pressed the reaction was “I wanted – eya eya o”. Well, what more I expect from 3 years old. She is no computer genius – she just learned to use notepad and paint on my machine. Finally, when I saw the above screen in detail, I realize that this screen was from the help screen and something got updated. I have been using SQL Server for a long time but I never updated help on the screen. When I need to search something if I remember that I have written it earlier I will go to http://search.sqlauthority.com and will search there or will search on Google. As this computer was already updated I fired up Virtual Machine and tried to look recreate how my daughter was reached to above screen. Here are the steps which I have to do to reach to above screen. Go to SSMS >> Toolbar >> Help >> Manage Help Settings (or type CTRL+ALT+F1) and click it. Above click brought up following screen. I clicked on Check for update online brought following screen up. When I clicked on Update it brought me back to original screen which my daughter was able to bring up earlier. I found it so interesting that what took me 2-3 minutes to figure out and the screen which I have never come across in my career I learned from my curiosity like my daughter.

  • Decal implementation

    - by dreta
    I had issues finding information about decals, so maybe this question will help others. The implementation is for a forward renderer. Could somebody confirm if i got decal implementation right? You define a cube of any dimension that'll define the projection volume in common space. You check for triangle intersection with the defined cube to recieve triangles that the projection will affect. You clip these triangles and save them. You then use matrix tricks to calculate UV coordinates for the saved triangles that'll reference the texture you're projecting. To do this you take the vectors representing height, width and depth of the cube in common space, so that f.e. the bottom left corner is the origin. You put that in a matrix as the i, j, k unit vectors, set the translation for the cube, then you inverse this matrix. You multiply the vertices of the saved triangles by this matrix, that way you get their coordinates inside of a 0 to 1 size cube that you use as the UV coordinates. This way you have the original triangles you're projecting onto and you have UV coordinates for them (the UV coordinates are referencing the texture you're projecting). Then you rerender the saved triangles onto the scene and they overwrite the area of projection with the projected image. Now the questions that i couldn't find answers for. Is the last point right? I've never done software clipping, but it seems error prone enough, due to limited precision, that the'll be some z fighting occuring for the projected texture. Also is the way of getting UV coordinates correct?

  • Android orientation change causes ImageView to dissapear

    - by Jarrod Smith
    Below is my layout for the row template in a SimpleCursorAdapter. The ImageView with id next_arrow disappears on orientation change. If I replace @drawable/arrow with @drawable/icon (copy of the standard sym_def_app_icon) it works fine. I thought it might be somehow related to the icons being of different dimensions, but I resized @drawable/icon to be the exact same dimensions as the arrow and it still worked fine while the arrow didn't. <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="90dp" android:background="@drawable/product_list_divider" android:paddingTop="10dp"> <ImageView android:src="@drawable/ninja_20_65" android:id="@+id/category_icon" android:layout_marginLeft="20dp" android:layout_marginRight="20dp" android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_marginTop="3dp"/> <LinearLayout android:orientation="vertical" android:layout_weight="5" android:layout_width="0dp" android:layout_height="wrap_content"> <TextView android:id="@+id/category_name" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Name" style="@style/CategoryHeading" android:layout_marginTop="5dp"/> <TextView android:id="@+id/category_description" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Description" style="@style/CategoryDescription"/> </LinearLayout> <ImageView android:src="@drawable/arrow" android:layout_weight="1" android:layout_width="0dp" android:layout_marginRight="10dp" android:layout_height="wrap_content" android:layout_marginTop="20dp" android:id="@+id/next_arrow"/> </LinearLayout>

  • c# Network Programming - HTTPWebRequest Scraping

    - by masterguru
    Hi, I am building a web scraping application. It should scrape a complex web site with concurrent HttpWebRequests from a single host to a single target web server. The application should run on Windows server 2008. One single HttpWebRequest for data could take from 1 minute to 4 minutes to complete (because of long running db operations) I should have at least 100 parallel requests to the target web server, but i have noticed that when i use more then 2-3 long-running requests i have big performance issues (request timeouts/hanging). How many concurrent requests can i have in this scenario from a single host to a single target web server? can i use Thread Pools in the application to run parallel HttpWebRequests to the server? will i have any issues with the default outbound HTTP connection/requests limits? what about Request timeouts when i reach outbound connection limits? what would be the best setup for my scenario? Any help would be appreciated. Thanks
