  • Send Click Message to another application process

    - by Nazar
    Hi Guys I have a scenario, i need to send click events to an independent application. I started that application with the following code. private Process app; app = new Process(); app.StartInfo.FileName = app_path; app.StartInfo.WorkingDirectory = dir_path; app.Start(); Now i want to send Mouse click message to that applicaiton, I have specific coordinates in relative to application window. How can i do it using Windows Messaging or any other technique. I used [DllImport("user32.dll")] private static extern void mouse_event(UInt32 dwFlags, UInt32 dx, UInt32 dy, UInt32 dwData, IntPtr dwExtraInfo); It works well but cause the pointer to move as well. So not fit for my need. Then i use. [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)] static extern IntPtr SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam); It works well for minimize maximize, but do not work for mouse events. The codes for mousevents i am using are, WM_LBUTTONDOWN = 0x201, //Left mousebutton down WM_LBUTTONUP = 0x202, //Left mousebutton up WM_LBUTTONDBLCLK = 0x203, //Left mousebutton doubleclick WM_RBUTTONDOWN = 0x204, //Right mousebutton down WM_RBUTTONUP = 0x205, //Right mousebutton up WM_RBUTTONDBLCLK = 0x206, //Right mousebutton do Thanks for the help in advance, and waiting for feedback.

  • ObjectDisposedException when .Show()'ing a form that shouldn't be disposed.

    - by user320781
    ive checked out some of the other questions and obviously the best solution is to prevent the behavior that causes this issue in the first place, but the problem is very intermittent, and very un-reproduceable. I basically have a main form, with sub forms. The sub forms are shown from menus and/or buttons from the main form like so: private void myToolStripMenuItem_Click(object sender, EventArgs e) { try { xDataForm.Show(); xDataForm.Activate(); } catch (ObjectDisposedException) { MessageBox.Show("ERROR 10103"); ErrorLogging newLogger = new ErrorLogging("10103"); Thread errorThread = new Thread(ErrorLogging.writeErrorToLog); errorThread.Start(); } } and the sub forms are actually in the main form(for better or worse. i would actually like to change this but would be a considerable amount of time to do so): public partial class FormMainScreen : Form { Form xDataForm = new xData(); ...(lots more here) public FormMainScreen(int pCount, string pName) { InitializeComponent(); ... } ... } The Dispose function for the sub form is modified so that, the 'close' and 'X' buttons actually hide the form so we dont have to re-create it every time. When the main screen closes, it sets a "flag" to 2, so the other forms know that it is actually ok to close; protected override void Dispose(bool disposing) { if (FormMainScreen.isExiting == 2) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); } else { if (xData.ActiveForm != null) { xData.ActiveForm.Hide(); } } } So, the question is, why would this work over and over and over again flawlessly, but, literally, about every 1/1000 of the time, cause an exception, or rather, why is my form being disposed? I had a suspicion that the garbage collector was getting confused, because it occurs slightly more frequently after it has been running for many hours.

  • "Outward" border-radius in css?

    - by MaxMackie
    Currently, the links at the top of my website look like this: However, I am trying to "round" the bottom edges of the buttons to make it look like they are coming out of the page and into the ribbon at the top. I am aware that you can hack it and add a "separator" div with rounded corners between each entry, but this would be difficult to do seeing at the borders used are not all from the same div. Also, it wouldn't be easy seeing as my buttons are very close to each other. The css for the "button": .button { border-top: 3px solid #A1C1BE; border-left: 3px solid #A1C1BE; border-right: 3px solid #A1C1BE; border-bottom: 0px; padding: 5px 8px 5px 8px; margin: 0 0 -9px 0; border-radius: 5px 5px 0 0; font-size: 12px; font-family: 'PT Sans', sans-serif; background-color: #f8f8ff; color: #484848; } css for the "ribbon": #top-wrapper { border-bottom: 5px solid #A1C1BE; width: 100%; background-color: #59554E; padding: 10px 0 0 0; color: #C0C0A8; } As you can see, the thicker border belongs to the ribbon which stretches the length of the webpage, whereas the thinner blue border is part of the button.

  • Playing video and audio in iPhone not working...

    - by Scott
    So we have buttons linked up to display images/videos/audio on click depending on a check we do earlier. That part works fine. It knows which one to play, however, when we click the buttons for video and audio, nothing happens. The image one works fine. The video and audio are being taken for a URL online, they are not local, but everywhere said this was still possible. Here is a little snippet of the code where we play the two files: if ( [fName hasSuffix:@".png"]) { NSLog(@"PICTURE"); NSURL *url = [NSURL URLWithString: fName]; UIImage *image = [UIImage imageWithData: [NSData dataWithContentsOfURL:url]]; self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; // self.view.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"MainBG.jpg"]]; [self.view addSubview:[[UIImageView alloc] initWithImage:image]]; } if ( [fName hasSuffix:@".mp4"]) { NSLog(@"VIDEO"); //NSString *path = [[NSBundle mainBundle] pathForResource:fName ofType:@"mp4"]; //NSLog(path); NSURL *url = [NSURL fileURLWithPath:fName]; MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:url]; [player play]; } if ( [fName hasSuffix:@".mp3"]) { NSLog(@"AUDIO"); NSURL *url = [NSURL fileURLWithPath:fName]; NSData *soundData = [NSData dataWithContentsOfURL:url]; AVAudioPlayer *avPlayer = [[AVAudioPlayer alloc] initWithData:soundData error: nil]; [avPlayer play]; } See anything wrong? By the way it compiles and runs, but nothing happens when we hit the button that executes that code.

  • JavaME - LWUIT images eat up all the memory

    - by Marko
    Hi, I'm writing a MIDlet using LWUIT and images seem to eat up incredible amounts of memory. All the images I use are PNGs and are packed inside the JAR file. I load them using the standard Image.createImage(URL) method. The application has a number of forms and each has a couple of labels an buttons, however I am fairly certain that only the active form is kept in memory (I know it isn't very trustworthy, but Runtime.freeMemory() seems to confirm this). The application has worked well in 240x320 resolution, but moving it to 480x640 and using appropriately larger images for UI started causing out of memory errors to show up. What the application does, among other things, is download remote images. The application seems to work fine until it gets to this point. After downloading a couple of PNGs and returning to the main menu, the out of memory error is encountered. Naturally, I looked into the amount of memory the main menu uses and it was pretty shocking. It's just two labels with images and four buttons. Each button has three images used for style.setIcon, setPressedIcon and setRolloverIcon. Images range in size from 15 to 25KB but removing two of the three images used for every button (so 8 images in total), Runtime.freeMemory() showed a stunning 1MB decrease in memory usage. The way I see it, I either have a whole lot of memory leaks (which I don't think I do, but memory leaks aren't exactly known to be easily tracked down), I am doing something terribly wrong with image handling or there's really no problem involved and I just need to scale down. If anyone has any insight to offer, I would greatly appreciate it.

  • What Javascript graphing package will let me plot points against a user-selected coordinate system?

    - by wes
    My customer has some specific requirements for a graph to show in our web app. We use HighCharts elsewhere in the app for more traditional graphing, but it doesn't seem to work for this situation. Their requirements: Allow the user to select a background image, set the scale and origin of the coordinate system. We'll graph our points against the user-defined coordinates. Points can be color coded Mouse-over boxes show more detail about the points Support for zooming and panning, scaling the background appropriately Less importantly: Support for drawing vectors off the points Some of this seems basic, but looking around at different graph packages, I was unable to find any with an example of this kind of usage. I've entertained the thought of just hacking it together in canvas myself, but I've never worked with canvas before so I don't think it would be cost effective. The basics of plotting points with a scaled coordinate system against an image background wouldn't be too hard, but the mouse-over details, zooming and panning sound much more daunting to me. More info: Right now we use jQuery, HighCharts, and ExtJS for our app. We tried flot in the past but switched to HighCharts after flot didn't meet our needs.

  • NSOpenGLFullScreen and SetSystemUIMode freeze bug!?

    - by Mattias
    Hi! I have a really strange problem which is perfectly re-producable using sample code! If I use Apple's NSOpenGLFullScreen sample I can click a button to enter fullscreen OpenGL mode. However if I click the mouse in the area where the menubar would be if I was running windowed mode, the entire program freezes because I really activate the menu-choice behind the OpenGL screen, so to speak. The solution I have found after some Googling is to use SetSystemUIMode to hide the menubar. Also I want to initiate the application to fullscreen at startup by adding a call to EnterFullScreen after initialization. Entering FullScreen works perfectly, BUT - if I add the call to SetSystemUIMode I get a really strange error! The entire screen hangs, the animation stops and no mouse coordinates seem to be reported. If I then exit the Fullscreen mode and press the FullScreen button again everything works and the menubar is gone.. What could be wrong here? I mean it obviously works to remove the menubar in that manner and it obviously works to enter fullscreen mode like that (using Cocoa), but why doesn't the combination work!? Pleeease help :) Sincerely, / Mattias

  • Can I add a portrait layout on top of a landscape Camera SurfaceView?

    - by Uwe Krass
    My application should hold a camera preview surface. The camera is fixed to landscape view via AndroidMainfest.xml <application android:icon="@drawable/icon" android:label="Camera"> <uses-library android:name="com.google.android.maps" /> <uses-feature android:name="android.hardware.camera" /> <uses-feature android:name="android.hardware.camera.autofocus" /> <activity android:name=".CameraPreview" android:label="Camera" android:screenOrientation="landscape"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> If there is another way to get the camera preview itself to behave correctly, please let me know. Now I need to have an overlay that holds a bunch of buttons. Due to usability, the user interface should be set to portrait view (or even better orientation aware). Is there a way to have a transparent layout (for buttons and other GUI elements) in portrait orientation? I tried to write a special rotated layout by extending a RelativeLayout, but the onDraw method isn't called at anytime. public class RotatedOverlay extends RelativeLayout { private static final String TAG = "RotatedOverlay"; public RotatedOverlay(Context context, AttributeSet attrs ) { super(context, attrs); } @Override protected void onDraw(Canvas canvas) { canvas.rotate(90); super.onDraw(canvas); } I am quite new to the Android plattform programming. Of course I dont know much about the programming tricks and workarounds yet. I did a lot of research over the last two weeks (even studied the native Camera implementation), but couldnt find a good solution so far. Maybe it works with two seperate Activities, but I dont think, that this can the right solution.

  • JqueryUI dialog box causes button to lose styling

    - by superexsl
    Hey everyone, I'm using JQueryUI dialog boxes and, while it works, it seems to remove any CSS styling on the button that opens the dialog. I have to manually refresh the page to get the styling back. An example button which launches the dialog: (button_submit is my CSS theme and launc_popup is used to detect the button click in JQuery. <asp:Button ID="btnLaunch" CssClass="button_sub launch_popup" runat="server" Text="Dialog..." CausesValidation="false" OnClientClick="return false;" /> My jquery: $('.launch_popup').click(function() { $("#dialog-form").dialog("open"); }); My dialog-form: $("#dialog-form").dialog({ autoOpen: false, height: 300, width: 300, modal: true, buttons: { 'Close': function() { $(this).dialog('close'); } } }); This happens to all the buttons that open dialogs. Is there a way to 'restyle' the button without refreshing the page? (It's in an updatepanel if that makes a difference, although this bit's client-side so not sure if that should affect it). Thanks for any help

  • jQueryUI Modal confirmation dialog on form submission

    - by DavidYell
    I am trying to get a modal confirmation dialog working when a user submits a form. My approach, I thought logically, would be to catch the form submission. My code is as follows, $('#multi-dialog-confirm').dialog({ autoOpen: false, height: 200, modal: true, resizable: false, buttons: { 'Confirm': function(){ //$(this).dialog('close'); return true; }, 'Cancel': function(){ $(this).dialog('close'); return false; } } }); $('#completeform').submit(function(e){ e.preventDefault(); var n = $('#completeform input:checked').length; if(n == 0){ alert("Please check the item and mark as complete"); return false; }else{ var q = $('#completeform #qty').html(); if(q > 1){ $('#multi-dialog-confirm').dialog('open'); } } //return false; }); So I'm setting up my dialog first. This is because I'm pretty certain that the scope of the dialog needs to be at the same level as the function which calls it. However, the issue is that when you click 'Confirm' nothing happens. The submit action does not continue. I've tried $('#completeform').submit(); also, which doesn't seem to work. I have tried removing the .preventDefault() to ensure that the form submission isn't completely cancelled, but it doesn't seem to make a difference between that and returning false. Not checking the box, show and alert fine. Might change to dialog at some point ;), clicking 'Cancel' closes the dialog and remains on the page, but the elusive 'Confirm' buttons seems to not continue with the form submission event. If anyone can help, I'd happily share my lunch with you! ;)

  • Get a selected radio button value after POST to set other fields enabled/disabled

    - by Redeemed1
    I have an MVC application with a simple control to all selection of All Dates or selecting a Date Range. The radio buttons have an onclick handler to enable/disable the dat pickers. All work well so far. When I try to set the correct context state for the datepickers after doing a POST I cannot get the jQuery selector to return the radio buttons checked value. The code is as follows: <%= Html.RadioButton("DateSelection.AllDates", "AllDates", Model.AllDates == "AllDates", new { onclick = "setReadOnly(this);" })%>ALL Dates&nbsp; <%= Html.RadioButton("DateSelection.AllDates", "Selection", Model.AllDates == "Selection", new { onclick = "setReadOnly(this);" })%>Selection <%= Html.DatePicker("DateSelection.startdate", Model.StartDate, "", "") %> &nbsp;To&nbsp;<%= Html.DatePicker("DateSelection.enddate", Model.EndDate, "", "") %><br /> The javascript is as follows: <script type="text/jscript" > function setReadOnly(obj) { if (obj.value == "Selection") { $('#DateSelection_startdate').css('backgroundColor', '#ffffff') .removeAttr('readonly') .datepicker('enable'); $('#DateSelection_enddate').css('backgroundColor', '#ffffff') .removeAttr('readonly') .datepicker('enable'); } else { $('#DateSelection_startdate').css('backgroundColor', '#eeeeee') .attr('readonly', 'readonly') .val('') .datepicker('disable'); $('#DateSelection_enddate').css('backgroundColor', '#eeeeee') .attr('readonly', 'readonly') .val('') .datepicker('disable'); } } <script type="text/jscript"> $(document).ready(function() { $('#DateSelection_startdate').datepicker('disable').css('backgroundColor', '#eeeeee') .attr('readonly', 'readonly') .val(''); $('#DateSelection_enddate').datepicker('disable').css('backgroundColor', '#eeeeee') .attr('readonly', 'readonly') .val(''); var selected = $('#DateSelection_AllDates:checked'); setReadOnly(selected); }); The javascript line that is causing the problem is var selected = $('#DateSelection_AllDates:checked'); which will NOT return the checked radio button. Using var selected = $('#DateSelection_AllDates'); will return the first radio button value as expected i.e. applying the ':checked' filter ALWAYS returns undefined. Can anyone see anything wrong here?

  • TinyMCE is glitchy/unusable in IE8

    - by Force Flow
    I'm using the jQuery version of TinyMCE 3.3.9.3 In firefox, it works fine (10 sec video depicting it in use): http://www.youtube.com/watch?v=TrAE0igfT3I In IE8 (in IE8 standards mode), I can't type or click any buttons. However, if I use ctrl+v to paste, then I can start typing, but the buttons still don't work (a 45 sec video depicting it in use): http://www.youtube.com/watch?v=iBSRlE8D8F4 The jQuery TinyMCE demo on TinyMCE's site works for me in IE8. Here's the init code: $().ready(function(){ function tinymce_focus(){ $('.defaultSkin table.mceLayout').css({'border-color' : '#6478D7'}); $('.defaultSkin table.mceLayout tr.mceFirst td').css({'border-top-color' : '#6478D7'}); $('.defaultSkin table.mceLayout tr.mceLast td').css({'border-bottom-color' : '#6478D7'}); } function tinymce_blur(){ $('.defaultSkin table.mceLayout').css({'border-color' : '#93a6e1'}); $('.defaultSkin table.mceLayout tr.mceFirst td').css({'border-top-color' : '#93a6e1'}); $('.defaultSkin table.mceLayout tr.mceLast td').css({'border-bottom-color' : '#93a6e1'}); } $('textarea.tinymce').tinymce({ script_url : 'JS/tinymce/tiny_mce.js', theme : "advanced", mode : "exact", invalid_elements : "b,i,iframe,font,input,textarea,select,button,form,fieldset,legend,script,noscript,object,embed,table,img,a,h1,h2,h3,h4,h5,h6", //theme options theme_advanced_buttons1 : "cut,copy,paste,pastetext,pasteword,selectall,|,undo,redo,|,cleanup,removeformat,|", theme_advanced_buttons2 : "bold,italic,underline,|,bullist,numlist,|,forecolor,backcolor,|", theme_advanced_buttons3 : "", theme_advanced_buttons4 : "", theme_advanced_toolbar_location : "top", theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : "none", theme_advanced_resizing : false, //plugins plugins : "inlinepopups,paste", dialog_type : "modal", paste_auto_cleanup_on_paste : true, setup: function(ed){ ed.onInit.add(function(ed){ //check for addEventListener -- primarily supported by firefox only var edDoc = ed.getDoc(); if ("addEventListener" in edDoc){ edDoc.addEventListener("focus", function(){ tinymce_focus(); }, false); edDoc.addEventListener("blur", function(){ tinymce_blur(); }, false); } }); } }); }); Any ideas as to why it's not working in IE8? [edit]: stripping everything out of the init (leaving just script_url and theme) results in the same symptoms

  • Issue on dojo onlick event on html button

    - by Cuong Le
    I am a new kid with dojo, I got weird issue which I take lots of time and have not yet found out, assume I have 4 buttons: <button id="btnMoveFirst" data-dojo-type="dijit.form.Button" iconclass="plusIcon"> &lt; &lt;</button> <button id="btnMovePrev" data-dojo-type="dijit.form.Button" iconclass="plusIcon"> &lt;</button> <button id="btnMoveNext" data-dojo-type="dijit.form.Button" iconclass="plusIcon"> &gt;</button> <button id="btnMoveLast" data-dojo-type="dijit.form.Button" iconclass="plusIcon"> &gt; &gt;</button> And use dojo with event onclick as below: dojo.connect(dijit.registry.byId('btnMoveFirst'), "onclick", function(evt){ alert('test1'); }); dojo.connect(dijit.registry.byId('btnMovePrev'), "onclick", function(evt){ alert('test2'); }); dojo.connect(dijit.registry.byId('btnMoveNext'), "onclick", function(evt){ alert('test3'); }); dojo.connect(dijit.registry.byId('btnMoveLast'), "onclick", function(evt){ alert('test4'); }); But when I click any one of 4 buttons, or even any button in form, I got 4 alerts instead of only correct one. Does anyone know this?

  • I would like to know how to put a "change image" layer like in facebook on a mouseover event

    - by netadictos
    Hello: I have a photo gallery I would like that every time a user does mouseover the image, there is a button on the top of this image that appears. The user can click on it. But every time that the user mouse out of the photo it must disappear. It works like the "change photo" in Facebook, with the photo of your profile. The problem I am having is that when I try to get over the button that appears (in my code is a link), it disappear because javascript understands that the mouse is just out of the image, even if this button/link is over the image. The image that I use is positioned absolutely over the image. This is my code, where you can see that I create a dom element that I append on the link of the image and then when there is a mouseout, I remove it. $('a.ftelement').mouseover(function() { var fav = $('<a></a>'); fav.attr("class","imgfavorito"); fav.attr("id","fav"+$J(this).attr("id")).html("<img src=\"/im/favorito.gif\"/>"); fav.appendTo(this); }); $('a.ftelement').mouseout(function() { $("a.imgfavorito").remove() }); The result is this graphically (http://www.freeimagehosting.net/uploads/41fbac8994.gif):

  • JavaFX 2.0 - How to change legend color of a LineChart dynamically?

    - by marie
    I am trying to style my JavaFX linechart but I have some trouble with the legend. I know how to change the legend color of a line chart in the css file: .default-color0.chart-series-line { -fx-stroke: #FF0000, white; } .default-color1.chart-series-line { -fx-stroke: #00FF00, white; } .default-color2.chart-series-line { -fx-stroke: #0000FF, white; } .default-color0.chart-line-symbol { -fx-background-color: #FF0000, white; } .default-color1.chart-line-symbol { -fx-background-color: #00FF00, white; } .default-color2.chart-line-symbol { -fx-background-color: #0000FF, white; } But this is not enough for my purposes. I have three or more colored toggle buttons and a series of data for every button. The data should be displayed in the same color the button has after I have selected the button. This should be possible with a multiselection of the buttons, so that more than one series of data can be displayed simultaneously. For the chart lines I have managed it by changing the style after I clicked the button: .. dataList.add(series); .. series.getNode().setStyle("-fx-stroke: rgba(" + rgba + ")"); If I deselect the button I remove the data from the list. dataList.remove(series); That is working fine for the strokes, but how can I do the same for the legend? You can see an example below. First I clicked the red button, thus the stroke and the legend is red (default-color0). After that I clicked the blue button. Here you can see the problem. The stroke is blue but the legend is green, because default color1 is used and I do not know how to change the legend color.

  • Help ! How do I get the total number rows from my SQL Server paging procedure ?

    - by The_AlienCoder
    Ok I have a table in my SQL Server database that stores comments. My desire is to be able to page though the records using [Back],[Next], page numbers & [Last] buttons in my data list. I figured the most efficient way was to use a stored procedure that only returns a certain number of rows within a particular range. Here is what I came up with @PageIndex INT, @PageSize INT, @postid int AS SET NOCOUNT ON begin WITH tmp AS ( SELECT comments.*, ROW_NUMBER() OVER (ORDER BY dateposted ASC) AS Row FROM comments WHERE (comments.postid = @postid)) SELECT tmp.* FROM tmp WHERE Row between (@PageIndex - 1) * @PageSize + 1 and @PageIndex*@PageSize end RETURN Now everything works fine and I have been able implement [Next] and [Back] buttons in my data list pager. Now I need the total number of all comments (not in the current page) so that I can implement my page numbers and the[Last] button on my pager. In other words I want to return the total number of rows in my first select statement i.e WITH tmp AS ( SELECT comments.*, ROW_NUMBER() OVER (ORDER BY dateposted ASC) AS Row FROM comments WHERE (comments.postid = @postid)) set @TotalRows = @@rowcount @@rowcount doesn't work and raises an error. I also cant get count.* to work either. Is there another way to get the total amount of rows or is my approach doomed.

  • Adapter for circle page indicator in android

    - by Charles LAU
    I am currently working on an android application which have multiple pages. I am trying to use Circle page indicator to allow users view multiple pages by flipping over the screen. Each page has seperate XML file for the view and each page has a button which is bind to a java method in the Activity. I would like to know how to initalise all the buttons in the Activity for multiple pages. Because at the moment, I can only initalise the button for the first page of the views. I cannot initalise the button for second and third page. Does anyone know how to achieve this. I have placed all the jobs to be done for all the buttons in a single activity. I am currently using this indicator : http://viewpagerindicator.com/ Here is my adapter for the circle page indicator: @Override public Object instantiateItem(View collection, int position) { inflater = (LayoutInflater) collection.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); int resid = 0; //View v = null;// inflater.inflate( R.layout.gaugescreen, (ViewPager)collection, false ); switch( position ) { case 0: resid = R.layout.gaugescreen; break; case 1: resid= R.layout.liveworkoutstatisticsscreen; break; case 2: resid = R.layout.mapscreen; break; default: resid = R.layout.gaugescreen; break; } View view = inflater.inflate(resid, null); ((ViewPager) collection).addView(view,0); return view; } Does anyone know how to achieve this?

  • UIButton only responds in a small area

    - by Tom Irving
    I'm trying to add a UIButton to a UIView, but am having some trouble with getting it to respond to touches. I have a method which returns UIButtons after I provide it with a tag: - (UIButton*)niceSizeButtonWithTag:(int)tag { UIButton * aButton = [UIButton buttonWithType:UIButtonTypeCustom]; [aButton setTag:tag]; [aButton addTarget:self action:@selector(buttonWasTapped:) forControlEvents:UIControlEventTouchUpInside]; CGRect newFrame = aButton.frame; newFrame.size.width = 44; newFrame.size.height = 44; [aButton setFrame:newFrame]; return aButton; } As you can see I'm creating a new button and increasing the size. I use this in the following way: UIButton * anotherButton = [self niceSizeButtonWithTag:1]; [anotherButton setImage:[UIImage imageNamed:@"image" withExtension:@"png"] forState:UIControlStateNormal]; [anotherButton setCenter:CGPointMake(middleOfView)]; [aView addSubview:anotherButton]; I create a lot of buttons like this, hence the reason for the method. The buttons are always created and added to the subview perfectly. I can see the image and they're in the correct position. The problem is that they only respond to touches in a tiny strip. In this attached image, The yellow shows the whole frame of the button, The red shows the area that will respond to touches. The grey shows a section of the view the button is added to. If anyone could shed some light on why this is happening, it would be really useful.

  • Determining when stringByEvaluatingJavaScriptFromString has finished

    - by alku83
    I have a UIWebView which loads up an HTML page. This page has two buttons on it, say Exit and Submit. I don't want users to be able to click the Exit button, so once the page has finished loading (ie. webViewDidFinishLoad is called), I use stringByEvaluatingJavaScriptFromString to remove one of these buttons, by manipulating the HTML. I also disable user interaction on the UIWebView on webViewDidStartLoad, and enable it again on webViewDidFinishLoad. The problem I am finding is that stringByEvaluatingJavaScriptFromString takes a second or two to complete, and it seems to be done in it's own thread. So what is happening is that webViewDidFinishLoad is called, user interaction is enabled on the UIWebView, and if the user is quick, they can click the Exit button before stringByEvaluatingJavaScriptFromString has finished. As stringByEvaluatingJavaScriptFromString seems to be on it's own thread with no way to know when it's finished (it doesnt call webViewDidFinishLoad), the only way to completely prevent users from tapping the Exit button that I can see is to only enable user interaction on the UIWebView after some delay, which is unreliable (how can I really know how long to delay for?). Am I correct in that stringByEvaluatingJavaScriptFromString is done on it's on thread, and I have no way of being able to tell when it's finished? Any other suggestions for how to get around this problem? EDIT: In short, what I want to know is if it is possible to disable a UIWebView while stringByEvaluatingJavaScriptFromString is executing, and re-enable the UIWebView when the javascript is finished. EDIT 2: There's an article here which seems to imply you can somehow poll the JS engine to see when it's finished, but I can't find any other references saying the same thing: http://drnicwilliams.com/2008/11/10/to-webkit-or-not-to-webkit-within-your-iphone-app/ EDIT 3 Based on the answer from Brad Smith, it seems that I actually need to know when the UIWebView has finished loading itself after the javascript has executed. It's looking more and more like I just need to put a delay of sorts in there.

  • Approaches to replace cursor in pure AS3 / Flare project?

    - by peteorpeter
    Hi there good lookin, I've got a pure AS3 (no Flex) project that uses Flare to display and interact with a data visualization. I just implemented some panning behavior, so you can click and drag the visualization around, and now I'd like to give the user a visual indicator that this is possible, by switching the arrow cursor with a nice grabby-looking hand icon. The user can click and drag at any time except when the mouse is over a clickable node (at which time the cursor swaps to a pointer - this behavior is already in place). So... 1) Do I need to create my own custom bitmap/sprite or is there a palette of built-in cursors I can use? (I'm not using Flex.) 2) Is there a way to simply replace the default arrow with the pan cursor project-wide, or do I need to attach the swapping to mouse events on display objects? Can I use the stage object to make this behavior apply everywhere? 3) How do I perform the swap? Do I use the Cursor object directly or do I need to get involved with the CursorManager? Any guidance, pseudo-code, or words of wisdom is greatly appreciated!

  • Controlling Movie Clips from the main time line instead of using their individual time lines?

    - by Jess
    I have a Flash website template (four pages) that I made using AS 3.0 and Flash CS4. It is for an assignment involving movie clips. Currently on the main time line there is only one frame, and three layers: actions/menu/content. The actionscript on the main time line is simply: content_mc.stop (); There is a movie clip on the stage called “Content” that contains the content for each of the pages. Inside of that there is a “Menu” movie clip that contains and controls all of the navigation buttons. The actionscript for the Menu movie clip is: function homeBtnPress (event:MouseEvent):void{ //comments here //comments here MovieClip(parent).content_mc.gotoAndStop("home"); } function aboutBtnPress (event:MouseEvent): void{ MovieClip(parent).content_mc.gotoAndStop ("about"); } function servicesBtnPress (event:MouseEvent): void{ MovieClip (parent).content_mc.gotoAndStop ("services"); } function contactBtnPress (event:MouseEvent): void{ MovieClip (parent).content_mc.gotoAndStop ("contact"); } function portfolioBtnPress (event:MouseEvent): void{ MovieClip (parent).content_mc.gotoAndStop ("portfolio"); } home.addEventListener(MouseEvent.CLICK, homeBtnPress); about.addEventListener(MouseEvent.CLICK, aboutBtnPress); services.addEventListener(MouseEvent.CLICK, servicesBtnPress); contact.addEventListener(MouseEvent.CLICK, contactBtnPress); portfolio.addEventListener(MouseEvent.CLICK, portfolioBtnPress); So everything works fine, but my instructor wants me to control the menu/content from the main time line by using the target path tool. What exactly would I target – just the “menu” and “content” movie clips, and what code would I use? Sorry if I'm not explaining very well, I'm pretty confused. Here is the feedback from my instructor: “While we learned how to control the main timeline and the timeline of another movie clip from within a movie clip, this is not the most intuitive way to script and makes for difficult debugging. So you will need to explore how to target your buttons inside of your menu movie clip and the frames within the content movie clip from the main timeline. “ Thanks so much in advance!

  • live.com setting can't be changed

    - by M M
    I'm on mail.live.com where, in the upper left corner it says "Windows Live™" and to the right of that it says "Hotmail([number])" "Messenger" "SkyDrive" "|" "MSN." Directly under the "Windows Live™," there is a square, bluish/gray avatar (with a generic, rotund peop with a head and trunk and arms). To the right of that there is a field (with a subtle, barely perceptible speech bubble-like arrow emanating from the avatar). But there's a word inside that field that I cannot get rid of. Coincidentally I think it's the same word I used as a search term a while back, having meant to put the search term in the "Search email and more" bing field on the other side of the screen. (Even that would have been by mistake because I had been aiming for the e-mail search field.) But it remains in the field connected to the avatar--and moreover the field is editable to the limited extent that a cursor can be placed into the field with a mouse click; the word just can't be deleted. I don't know if the avatar should be there either, but I'd rather have just simply that than the word next to it continuously there for time immemorial. If I click into the field hoping to delete the word, I'm confronted with options along the bottom of the same field (now expanded by my mouse click): "Add: Photo Link Document," and a button that says "Share" and an [X] to reduce the field back to its default state--which still contains the word I'm trying to delete.

  • How to get a JTextField event that started a pop up menu in Java ?

    - by Frank
    I have a JTextField that represents a day, such as "Sunday", when I left mouse click on it, it changes background color, when I right mouse click on it, a pop up menu comes up, after I click on a menu item, such as "1st of month", it gets the value, closes the menu and then change the bgcolor, my code looks like this : JTextField dayHeading=new JTextField("Su"); ...... final JPopupMenu Pmenu; JMenuItem menuItem; Pmenu=new JPopupMenu(); menuItem=new JMenuItem("1st of month"); Pmenu.add(menuItem); menuItem=new JMenuItem("2nd of month"); Pmenu.add(menuItem); ...... menuItem.addMouseListener(new MouseAdapter() { public void mouseReleased(final MouseEvent e) { System.out.println(((JMenuItem)e.getComponent()).getText()); onHeadingClicked(e); // Error : java.lang.ClassCastException: javax.swing.JMenuItem cannot be cast to javax.swing.JTextField // How to get the orininal JTextField event that started this pop up menu, so I can pass it onto onHeadingClicked() ? } }); ...... dayHeading.setEditable(false); dayHeading.setFocusable(false); dayHeading.addMouseListener(new MouseAdapter() { public void mouseReleased(final MouseEvent evt) { if (SwingUtilities.isLeftMouseButton(evt)) onHeadingClicked(evt); else if (SwingUtilities.isRightMouseButton(evt)) Pmenu.show(evt.getComponent(),evt.getX(),evt.getY()); } }); ...... void onHeadingClicked(final java.awt.event.MouseEvent evt) { final javax.swing.JTextField fld=(javax.swing.JTextField) evt.getSource(); ... } My question is : in the menuItem.addMouseListener section, how to get the orininal JTextField event that started this pop up menu, so I can pass it onto onHeadingClicked() ?

  • How to allow click-through and a cursor in a background app while not taking the active appearance a

    - by Peter Hosey
    Here are my goals: My application displays an overlay window above all applications' window. The user can draw in the overlay window. The mouse cursor changes to a specific cursor while in the overlay window. The application that has the active appearance before summoning the overlay window still has it while the overlay window is up and usable. The user does not need to click on the overlay window to activate it before they can draw. Drawing in the window does not steal the active appearance away from the application that has it. With LSUIElement, I get #1, #2, #3, and #5. With LSBackgroundOnly, I get #1, #2, #4, and #6. How can I satisify all of these goals without installing an event tap and processing the mouse events myself? Things I've tried: [NSApp preventWindowOrdering] in mouseDown: [NSApp activateIgnoringOtherApps:YES] in applicationWillFinishLaunching: [myWindow orderFront:nil] in applicationWillFinishLaunching: [myWindow makeKeyAndOrderFront:nil] in applicationWillFinishLaunching: [myWindow orderFrontRegardless] in applicationWillFinishLaunching: [myWindow makeMainWindow] in applicationWillFinishLaunching: (this caused failure of point 4 even with LSBackgroundOnly) SetThemeCursor in applicationWillFinishLaunching: (With LSUIElement) Implementing canBecomeMainWindow in my NSPanel subclass to return NO Except where otherwise noted, none of these made any difference. So, with LSUIElement, goals #4 and #6 remain; with LSBackgroundOnly, goals #3 and #5 remain. Any suggestions?

  • GWT: Populating a page from datastore using RPC is too slow

    - by Ilya Boyandin
    Is there a way to speed up the population of a page with GWT's UI elements which are generated from data loaded from the datastore? Can I avoid making the unnecessary RPC call when the page is loaded? More details about the problem I am experiencing: There is a page on which I generate a table with names and buttons for a list of entities loaded from the datastore. There is an EntryPoint for the page and in its onModuleLoad() I do something like this: final FlexTable table = new FlexTable(); rpcAsyncService.getAllCandidates(new AsyncCallback<List<Candidate>>() { public void onSuccess(List<Candidate> candidates) { int row = 0; for (Candidate person : candidates) { table.setText(row, 0, person.getName()); table.setWidget(row, 1, new ToggleButton("Yes")); table.setWidget(row, 2, new ToggleButton("No")); row++; } } ... }); This works, but takes more than 30 seconds to load the page with buttons for 300 candidates. This is unacceptable. The app is running on Google App Engine and using the app engine's datastore.
