• Qt 4.x: how to implement drag-and-drop onto the desktop or into a folder?

  - by Jeremy Friesner

  Hi all, I've written a little file-transfer application written in C++ using Qt 4.x ... it logs into a server, shows the user a list of files available on the server, and lets the user upload or download files. This all works fine; you can even drag a file in from the desktop (or from an open folder), and when you drop the file icon into the server-files-list-view, the dropped file gets uploaded to the server. Now I have a request for the opposite action as well... my users would like to be able to drag a file out of the server-files-list-view and onto the desktop, or into an open folder window, and have that file get downloaded into that location. That seems like a reasonable request, but I don't know how to implement it. Is there a way for a Qt application to find out the directory corresponding to where "drop event" occurred, when the icon was dropped onto the desktop or into an open folder window? Ideally this would be a Qt-based platform-neutral mechanism, but if that doesn't exist, then platform-specific mechanisms for MacOS/X and Windows (XP or higher) would suffice. Any ideas?

• SWT: problems with clicking button after using setEnabled() on Linux

  - by Laimoncijus

  Hi, I have a strange case with SWT and Button after using setEnabled() - seems if I disable and enable button at least once - I cannot properly click with mouse on it anymore... Already minify code to very basic: import org.eclipse.swt.SWT; import org.eclipse.swt.events.SelectionEvent; import org.eclipse.swt.events.SelectionListener; import org.eclipse.swt.layout.GridLayout; import org.eclipse.swt.widgets.Button; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Shell; public class TestButton { public TestButton() { Display display = new Display(); Shell shell = new Shell(display); GridLayout mainLayout = new GridLayout(); shell.setLayout(mainLayout); shell.setSize(100, 100); Button testButton = new Button(shell, SWT.PUSH); testButton.addSelectionListener(new TestClickListener()); testButton.setText("Click me!"); //testButton.setEnabled(false); //testButton.setEnabled(true); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); } class TestClickListener implements SelectionListener { @Override public void widgetDefaultSelected(SelectionEvent e) { } @Override public void widgetSelected(SelectionEvent e) { System.out.println("Click!"); } } public static void main(String[] args) { new TestButton(); } } When I keep these 2 lines commented out - I can properly click on a button and always get "Click!" logged, but if I uncomment them - then I can't click on button properly with mouse anymore - button visually seems to be clicked, but nothing is logged... Am I doing something wrong here? Or maybe it's some kind of bug on Linux platform? Because on Mac running the same code I never experienced such problems... Thanks for any hint! P.S. Running code on Ubuntu 9.10, Gnome + Compiz, Sun Java 1.6.0.16

• Disabling redraw in WinForms app

  - by Ryan

  I'm working on a C#.Net application which has a somewhat annoying bug in it. The main window has a number of tabs, each of which has a grid on it. When switching from one tab to another, or selecting a different row in a grid, it does some background processing, and during this the menu flickers as it's redrawn (File, Help, etc menu items as well as window icon and title). I tried disabling the redraw on the window while switching tabs/rows (WM_SETREDRAW message) at first. In one case, it works perfectly. In the other, it solves the immediate bug (title/menu flicker), but between disabling the redraw and enabling it again, the window is "transparent" to mouse clicks - there's a small window (<1 sec) in which I can click and it will, say, highlight an icon on my desktop, as if the app wasn't there at all. If I have something else running in the background (Firefox, say) it will actually get focus when clicked (and draw part of the browser, say the address bar.) Here's code I added. m = new Message(); m.HWnd = System.Windows.Forms.Application.OpenForms[0].Handle; //top level m.WParam = (IntPtr)0; //disable redraw m.LParam = (IntPtr)0; //unused m.Msg = 11; //wm_setredraw WndProc(ref m); <snip - Application ignores clicks while in this section (in one case) m = new Message(); m.HWnd = System.Windows.Forms.Application.OpenForms[0].Handle; //top level m.WParam = (IntPtr)1; //enable m.LParam = (IntPtr)0; //unused m.Msg = 11; //wm_setredraw WndProc(ref m); System.Windows.Forms.Application.OpenForms[0].Refresh(); Does anyone know if a) there's a way to fix the transparent-application problem here, or b) if I'm doing it wrong in the first place and this should be fixed some other way?

• How can I get the Name of the Program associated with a file extension using Delphi?

  - by lkessler

  I need to get the name of the program currently associated with a file extension for the current user. If you right-click on a file and select properties, then what I need is the program name that is to the right of the "Opens with" line. e.g. For ".xls", I want to be able to get the answer "Microsoft Office Excel", or whatever program the user has as their default program to open .xls files. I have determined it's not as easy as just going into HKEY_CLASSES_ROOT and picking it out, since it may also be specified in HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER or HKEY_USERS. Maybe all I need to know is the pecking order used by Windows to determine this and how to get to each of the locations. Of course, a Windows API call to do this would be ideal. This is a similar question to: How to get icon and description from file extension using Delphi? but that question only answered how to get the description of the extension and the icon of the associated program. I couldn't find a way to extend that to also get the name of the associated program.

• jQuery change CSS background position and mouseover/mouseout

  - by steelfrog

  I have a menu composed of a single image (e.g., sprites). In order to display the hover image, I simply move the background image down. I'd like this effect to be controlled by jQuery and animated. This is a sample menu item. <ul> <li id="home"><a href="#"></a></li> </ul> This is what I'm toying with. I'm very new to jQuery and am having problems getting the proper selector going. $(document).ready(function(){ $('#home a'); // Set the 'normal' state background position .css( {backgroundPosition: "0 0"} ) // On mouse over, move the background .mouseover(function(){ $(this).stop().animate({backgroundPosition:"(0 -54px)"}, {duration:500}) }) // On mouse out, move the background back .mouseout(function(){ $(this).stop().animate({backgroundPosition:"(0 0)"}, {duration:500}) }) }); Could you point out what I'm doing wrong? I know the selector is probably incorrect but I'm having a hard time figuring out how to manipulate the anchor.

• Set initial view with SkpWriter in Google Sketchup C++ SDK

  - by Peter Olsson

  How do you set the initial view for the model in an SKP file created with the SkpWriter in Google Sketchup C++ SDK? There has been an example in an older version of the SDK. Part of the source is posted here. I'm trying to use: m_pDoc->GetModel()->SetCamera(cameraDefn); The problem is that I'm not able to create a valid atlast::sketchup::CCameraDefinition. Non of the examples in the above post works: atlast::sketchup::CCameraDefinition cameraDefn; cameraDefn.Set(atlast::geometry::CPoint3d(793.838, -1262.6, 2603.16), atlast::geometry::CPoint3d(567.977, 338.199, 398.932), atlast::geometry::CUnitVector3d(-0.112657, 0.798459, 0.591415)); and: atlast::sketchup::CCameraDefinition cameraDefn; cameraDefn.Set(atlast::geometry::CPoint3d(793.838, -1262.6, 2603.16), atlast::geometry::CPoint3d(567.977, 338.199, 398.932), atlast::geometry::CUnitVector3d(-0.112657, 0.798459, 0.591415)); In the end I want the initial view to be the view you get from pressing the icon for Zoom extents followed by the Iso icon (the other way around is also ok). Right now I would settle for creating a valid atlast::sketchup::CCameraDefinition. Any better way to achieve this in the SKP-file?

• Link to RSS/Atom feed, relative, doesn't work in Firefox

  - by Adrian Smith

  I have a weird problem. I generate a HTML page, hosted let's say at http://www.x.com/stuff which contains <head> <link type="application/atom+xml" rel="alternate" href="/stuff/feed"/> .. </head> The result is: In IE7 all works well - you can click on the feed icon in the browser and the feed is displayed In Firefox, view source, click on the linked /stuff/feed and you see the source of the feed, so that works as expected In Firefox, view the page (not source), then click on the feed icon in the address bar, I get an error that it can't retrieve the URL feed://http//www.x.com/stuff/feed So the problem is, that it's appending feed:// to the front of the URL and then taking out the colon : after the http. I understand that feed: is HTTP anyway so perhaps the adding of that isn't a big problem. But anyway, the fact is, that URL Firefox generates out of my <link> tag doesn't work. I have considered making the URL absolute, but I haven't found any evidence that those URLs have to be absolute, nor can I understand why that would be the case. And for various reasons it would be inconvenient in my code to generate an absolute URL. I can do it if necessary but I would prefer to see proof (e.g. specification, or Mozilla bug report) that it's necessary before making my code messy What do you think? Does anyone know of any evidence that the URL should be absolute? Or am I doing something else wrong? It seems such a simple/obvious tag, where nothing could go wrong, but I can't get it to work.

• jqGrid zebra striping problem

  - by ShiVik

  Hello all I have just started with jQuery. I am trying to implement zebra striping in my jqGrid class. I am having the problem when user clicks on sort column, all rows get rearranged and the zebra striping is blown away. Zebra Striping code $("#item_table tbody tr:odd").addClass("alt"); $("#item_table tbody tr").mouseover(function() { $(this).addClass("over"); }); $("#item_table tbody tr").mouseout(function() { $(this).removeClass("over"); }); jqGrid code jQuery.extend(jQuery.jgrid.defaults, { autowidth: true, hidegrid: false, colModel:[ { name: 'icon', index: 'icon', width: 0, resizable: false }, { name: 'name', index: 'name', width: 0, resizable: false }, { name: 'price', index: 'price', width: 0, sorttype: "int", resizable: false } ], onSortCol: function(index, iCol, sortorder) { // This doesn't work - IT SHOULDN'T EITHER, since event is called // just after clicking to sort but before actual sorting jQuery("#item_table tbody tr:odd").addClass("odd"); }, caption: "Item Table" }); I also tried loadComplete, gridComplete events, but to no avail. How should I proceed with this? Have I even started this right? Regards Vikram

• Web Start Application built on NetBeans Platform doesn't create desktop shortcut & start menu item

  - by rudolfv

  I've created a NetBeans Platform application that is launched using Java Web Start. I built the WAR file using the 'Build JNLP Application'-command in Netbeans. I've added a desktop shortcut and menu item to the JNLP file, but for some reason, these are not created when the application is launched. However, when I go to: Control Panel - Java - Temporary Internet Files - View - Select my application Click 'Install shortcuts to the selected application' the desktop and menu shortcuts are created correctly. Also, in the Java Console, the Shortcut Creation option is set to the following (the default, I presume): Prompt user if hinted Below is a snippet of my JNLP file: <jnlp spec="6.0+" codebase="$$codebase"> <information> <title>${app.title}</title> <vendor>SomeVendor (Pty) Ltd</vendor> <description>Some description</description> <icon href="${app.icon}"/> <shortcut online="true"> <desktop/> <menu submenu="MyApp"/> </shortcut> </information> ... I'm stumped. Does anybody have an explanation for this? Thanks PS This is on both Windows XP and Windows 7. NetBeans version: 6.8

• jQuery ui Accordion degrades in IE6 or IE7, but is working in IE8

  - by cfree

  There are two accordions on my page, with custom accordion CSS in another file, differentiated by class and ID names so as not to conflict with each other. The accordions don't show up at all, they just degrade to showing all the content at once, as if all the accordion styling is gone. The accordions are both called around the middle of the page, and there's no difference if they are loaded with $(document).ready. What should I check for in the CSS files? There are no inline-block uses. I am using jQuery 1.3.2.min and jQuery ui 1.7.2, so I'm assuming the autoHeight set to false won't make a difference... This is being used inside a Symfony-based site. Works fine in FF, IE8, Chrome. Not so much in IE6, IE7/IE8 compatibility mode. $(function() { $("#accordion").accordion({ active: false, autoHeight: false, collapsible: true, icons: { 'header': 'ui-icon-carat-1-e', 'headerSelected': 'ui-icon-carat-1-s' }, }); $(".links").accordion({ active: false, autoHeight: false, collapsible: true }); });

• (solved) jQuery click and drag/scroll window: jagged movement

  - by Josh

  Edit: derp, using pageX/Y instead of clientX/Y -- apparently scrollBy expects input with that offset rather than the other. Jaggy movement gone. I am getting jagged movement when doing small scroll increments using the following bindings. Can anyone point me in the right direction for how to smooth this out? FYI, its intermittent. It seems like, if I click and hold for a second, then drag at a decent speed there are no problems. Edit: What the hell? I get this output on debug... obvious jog backwards and forwards. This will happen in succession and seems to have no correlation with the mouse, other than the mouse is moving. x 398 : 403 y 374 : 377 x 403 : 399 y 377 : 374 x 399 : 404 y 374 : 377 Josh sococo.client.panMap = function(e){ e.preventDefault(); var movex = sococo.client.currX - e.pageX ; var movey = sococo.client.currY - e.pageY; console.log( sococo.client.currX +" : " + e.pageX ); window.scrollBy(movex,movey); sococo.client.currY = e.pageY; sococo.client.currX = e.pageX; } $(document).mousedown( function(e){ e.preventDefault(); sococo.client.currX = e.pageX; sococo.client.currY = e.pageY; $(document).bind( "mousemove", sococo.client.panMap ); }); $(document).mouseup( function(e){ e.preventDefault(); $(document).unbind( "mousemove", sococo.client.panMap ); });

• How to stop my firefox extension which interferes other extension?

  - by ccppjava

  Hi, I have tried very hard to make my extension as simple as possible, it now do not contain any skin/css, it just have 'statusbar' in one single 'overlay'. The issue is that when installed, it hides the top three icon of 'all-in-one toolbar' extension of my firefox 3.6.3. On other two machine which do not have 'all-in-one toolbar', it hide all the icons of the web-development toolbar! chrome.manifest content stackoverflow content/ content stackoverflow content/ contentaccessible=yes overlay chrome://browser/content/browser.xul chrome://stackoverflow/content/browser.xul locale stackoverflow en-US locale/en-US/ browser.xul <overlay id="dch-browser-overlay" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"> <script type="application/x-javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"/> <script src="stackoverflow.js" /> <statusbar id="status-bar"> <statusbarpanel id="stackoverflow-status-bar-icon" class="statusbarpanel-iconic" src="chrome://stackoverflow/content/icon_small.png" tooltiptext="&runstackoverflow;" onclick="stackoverflow.run()" /> </statusbar> </overlay> I have tried very hard to simplify the extension to find the reason, but failed, any suggestion/ideas would be welcome. thx.

• How to keep my topmost window on top?

  - by Misko Mare

  I will first explain why I need it, because I anticipate that the first response will be "Why do you need it?". I want to detect when the mouse cursor is on an edge of the screen and I don't want to use hooks. Hence, I created one pixel wide TOPMOST invisible window. I am using C++ on Win XP, so when the window is created (CreateWindowEx(WS_EX_TOPMOST | WS_EX_TRANSPARENT ...) everything works fine. Unfortunately, if a user moves another topmost window, for example the taskbar over my window, I don't get mouse movements. I tried to solve this similarly to approaches suggested in: How To Keep an MDI Window Always on Top I tried to check for Z-order of my topmost window in WM_WINDOWPOSCHANGED first with case WM_WINDOWPOSCHANGED : WINDOWPOS* pWP = (WINDOWPOS*)lParam; yet pWP-hwnd points to my window and pWP-hwndInsertAfter is 0, which should mean that my window is on the top of the Z, even though it is covered with the taskbar. Then I tried: case WM_WINDOWPOSCHANGED : HWND topWndHndl = GetNextWindow(myHandle, GW_HWNDPREV) GetWindowText(topWndHndl, pszMem, cTxtLen + 1); and I'll always get that the "Default IME" window is on top of my window. Even if try to bring my window to the top with SetWindowPos() or BringWindowToTop (), "Default IME" stays on the top. I don't know what is "Default IME" and how to detect if the taskbar is on top of my window. So my question is: How to detect that my topmost window is not the top topmost window anymore and how to keep it on the top? P.S. I know that a "brute force" approach of periodically bringing my window to the top works, yet is ugly and could have some unwanted inference with the notification window for example. (Bringing my window to the top will hide the notification window.) Thank you on your time and suggestions!

• JScrollPanel without scrollbars

  - by Erik Itland

  I'm trying to use a JScrollPanel to display a JPanel that might be too big for the containing Jpanel. I don't want to show the scrollbars (yes, this is questionable UI design, but it is my best guess of what the customer wants. We use the same idea other places in the application, and I feel this case have given me enough time to ponder if I can do it in a better way, but if you have a better idea I might accept it an answer.) First attempt: set verticalScrollBarPolicy to NEVER. Result: Scrolling using mouse wheel doesn't work. Second attempt: set the scrollbars to null. Result: Scrolling using mouse wheel doesn't work. Third attempt: set scrollbars visible property to false. Result: It is immidiately set visible by Swing. Fourth attempt: inject a scrollbar where setVisible is overridden to do nothing when called with true. Result: Can't remember exactly, but I think it just didn't work. Fifth attempt: inject a scrollbar where setBounds are overridden. Result: Just didn't look nice. (I might have missed something here, though.) Sixth attempt: ask stackoverflow. Result: Pending. Scrolling works once scrollbars are back.

• Modify shell script to monitor/ping multiple ip addresses

  Alright so I need to constantly monitor multiple routers and computers, to make sure they remain online.

• Delphi - Populate an imagelist with icons at runtime 'destroys' transparency

  - by ben

  Hi again, I've spended hours for this (simple) one and don't find a solution :/ I'm using D7 and the TImageList. The ImageList is assigned to a toolbar. When I populate the ImageList at designtime, the icons (with partial transparency) are looking fine. But I need to populate it at runtime, and when I do this the icons are looking pretty shitty - complete loose of the partial transparency. I just tried to load the icons from a .res file - with the same result. I've tried third party image lists also without success. I have no clue what I could do :/ Thanks 2 all ;) edit: To be honest I dont know exactly whats going on. Alpha blending is the correkt term... Here are 2 screenies: Icon added at designtime: Icon added at runtime: Your comment that alpha blending is not supported just brought the solution: I've edited the image in an editor and removed the "alpha blended" pixels - and now it looks fine. But its still strange that the icons look other when added at runtime instead of designtime. If you (or somebody else ;) can explain it, I would be happy ;) thanks for you support!

• ActionScript - clicking and determining the sprite's class

  - by TheDarkIn1978

  i'd like to add all or most of my mouse events to stage, but in order to do that i need to be able to tell what is the type of the sprite being clicked. i've added two sprites to the display list, one of which is from a class called Square, the other from a class called Circle. var mySquare:Sprite = new Square(); var myCircle:Sprite = new Circle(); addChild(mySquare); addChild(myCircle); now when i click on these sprites, i'd like to know from which class they are from, or which type of sprite it is. //mousePoint returns mouse coordinates of the stage var myArray:Array = stage.getObjectsUnderPoint(mousePoint()); if (myArray[myArray.length - 1] is Sprite) ... so far i know how to do is determine if it IS a sprite display object, but since i'll only be working with sprites i need something more specific. rather than checking "is Sprite", is there a way i can check "is Square" or "is Circle"? if (myArray[myArray.length - 1] is Square)

• How can Safari be prevented from scrolling an overflow:hidden iframe?

  - by Alexander Ljungberg

  With Safari you can disable most iframe scrolling by setting style="overflow: hidden;" on the iframe. However, if you click in the iframe and move the mouse the content scrolls anyhow. Example: <html> <body> <iframe style="width: 100%; height:100px; overflow: hidden;" scrolling="no" src="scrollcontent.html"> </iframe> </body> </html> scrollcontent.html: <html scroll="no" style="overflow:hidden;"> <body scroll="no" style="overflow:hidden;"> <div style="background-color: green; height:100px;">A</div> <div style="background-color: red; height:100px;">B</div> </body> </html> In this example, the iframe should only show a green area and it should be impossible to reveal the red area. This is mostly true: there is no scrollbar, the mouse wheel doesn't do anything and neither do the arrow keys. However click and drag still scrolls the view. This is particularly noticeable when selecting text. Does anyone know any trick to stop Safari from doing this?

• Binding event handlers to specific elements, using bubbling (JavaScript/jQuery)

  - by Bungle

  I'm working on a project that approximates the functionality of Firebug's inspector tool. That is, when mousing over elements on the page, I'd like to highlight them (by changing their background color), and when they're clicked, I'd like to execute a function that builds a CSS selector that can be used to identify them. However, I've been running into problems related to event bubbling, and have thoroughly confused myself. Rather than walk you down that path, it might make sense just to explain what I'm trying to do and ask for some help getting started. Here are some specs: I'm only interested in elements that contain a text node (or any descendant elements with text nodes). When the mouse enters such an element, change its background color. When the mouse leaves that element, change its background color back to what it was originally. When an element is clicked, execute a function that builds a CSS selector for that element. I don't want a mouseover on an element's margin area to count as a mouseover for that element, but for the element beneath (I think that's default browser behavior anyway?). I can handle the code that highlights/unhighlights, and builds the CSS selector. What I'm primarily having trouble with is efficiently binding event handlers to the elements that I want to be highlightable/clickable, and avoiding/stopping bubbling so that mousing over a (<p>) element doesn't also execute the handler function on the <body>, for example. I think the right way to do this is to bind event handlers to the document element, then somehow use bubbling to only execute the bound function on the topmost element, but I don't have any idea what that code looks like, and that's really where I could use help. I'm using jQuery, and would like to rely on that as much as possible. Thanks in advance for any guidance!

• Android - Correspondence between ImageView coordinates and Bitmap Pixels

  - by Matteo

  In my application I want the user to be able to select some content of an Image contained inside an ImageView. To select the content I subclassed the ImageView class making it implement the OnTouchListener so to draw over it a rectangle with borders decided by the user. Here is an example of the result of the drawing (to have an idea you can think of it as when you click with the mouse on your desktop and drag the mouse): Now I need to determine which pixels of the Bitmap image correspond to the selected part. It's kind of easy to determine which are the points of the ImageView belonging to the rectangle, but I don't know how to get the correspondent pixels, since the ImageView has a different aspect ratio than the original image. I followed the approach described especially here, but also here, but am not fully satisfied because in my opinion the correspondence made is 1 on 1 between pixels and points on the ImageView and does not give me all the correspondent pixels on the original image to the selected area. Calling hoveredRect the rectangle on the ImageView the points inside of it are: class Point { float x, y; @Override public String toString() { return x + ", " + y; } } Vector<Point> pointsInRect = new Vector<Point>(); for( int x = hoveredRect.left; x <= hoveredRect.right; x++ ){ for( int y = hoveredRect.top; y <= hoveredRect.bottom; y++ ){ Point pointInRect = new Point(); pointInRect.x = x; pointInRect.y = y; pointsInRect.add(pointInRect); } } How can I obtain a Vector<Pixels> pixelsInImage containing the correspondent pixels?

• Why are mercurial subrepos behaving as unversioned files in eclipse AND torotoiseHG

  - by noam

  I am trying to use the subrepo feature of mercurial, using the mercurial eclipse plugin\tortoiseHG. These are the steps I took: Created an empty dir /root cloned all repos that I want to be subrepos inside this folder (/root/sub1, /root/sub2) Created and added the .hgsub file in the root repo /root/.hgsub and put all the mappings of the sub repos in it using tortoiseHG, right clicked on /root and selected create repository here again with tortoise, selected all the files inside /root and added them to to the root repo commited the root repo pushed the local root repo into an empty repo I have set up on kiln Then, I pulled the root repo in eclipse, using import-mercurial. Now I see that all the subrepos appear as though they are unversioned (no "orange cylinder" icon next to their corresponding folders in the eclipse file explorer). Furthermore, when I right click on one of the subrepos, I don't get all the hg commands in the "team" menu as I usually get, with root projects - no "pull", "push" etc. Also, when I made a change to a file in a subrepo, and then "committed" the root project, it told me there were no changes found. I see the same behavior also in tortoiseHG - When I am browsing files under /root, the files belonging directly to the root repo have an small icon (a V sign) on them marking they are version controlled, while the subrepos' folders aren't marked as such. Am I doing something wrong, or is it a bug?

• Scale transform in xaml (in a controltemplate) on a button to perform a "zoom"

  - by Matt B

  Hi all, I've got a button with an image in it and it's being styled by the following: <ControlTemplate x:Key="IconButton" TargetType="Button"> <Border> <ContentPresenter Height="80" Width="80" /> </Border> <ControlTemplate.Triggers> <EventTrigger RoutedEvent="Button.Click"> <BeginStoryboard> <Storyboard TargetProperty="Opacity"> <DoubleAnimation From="1" To="0.5" Duration="0:0:0.5" /> <DoubleAnimation From="0.5" To="1" Duration="0:0:0.5" /> </Storyboard> </BeginStoryboard> </EventTrigger> <EventTrigger RoutedEvent="Mouse.MouseEnter"> <BeginStoryboard> <Storyboard TargetProperty="Width"> <DoubleAnimation From="80" To="95" Duration="0:0:0.2" /> </Storyboard> </BeginStoryboard> </EventTrigger> <Trigger Property="IsMouseOver" Value="True"> <Setter Property="Cursor" Value="Hand"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> Button is as follows: <Button Template="{StaticResource IconButton}" Name="btnExit"> <Image Source="Images/Exit.png" /> </Button> The problem is that the width doesn't change when my mouse goes over. (Or at least - the width of the image does not...) I believe there is a "scale" transform I can use to enlarge the button and all it's contents? how would I do that here...? Thanks.

• Primefaces push encoding

  - by kalaoke

  I use primefaces push to write a message in a p:notificationBar. if i push a message with specials characters (like russians char), I've got '?' in my message. How can I fix this problem ? Thanks for your help. (config : primefaces 3.4 and jsf2. All my html pages are utf8 encoding). Here is my view code : <p:notificationBar id="bar" widgetVar="pushNotifBar" position="bottom" style="z-index: 3;border: 8px outset #AB1700;width: 97%;background: none repeat scroll 0 0 #CA837D;"> <h:form prependId="false"> <p:commandButton icon="ui-icon-close" title="#{messages['gen.close']}" styleClass="ui-notificationbar-close" type="button" onclick="pushNotifBar.hide();"/> </h:form> <h:panelGrid columns="1" style="width: 100%; text-align: center;"> <h:outputText id="pushNotifSummary" value="#{growlBean.summary}" style="font-size:36px;text-align:center;"/> <h:outputText id="pushNotifDetail" value="#{growlBean.detail}" style="font-size: 20px; float: left;" /> </h:panelGrid> </p:notificationBar> <p:socket onMessage="handleMessage" channel="/notifications"/> <script type="text/javascript"> function handleMessage(data) { var substr = data.split(' %% '); $('#pushNotifSummary').html(substr[0]); $('#pushNotifDetail').html(substr[1]); pushNotifBar.show(); } </script> and my Bean code : public void send() { PushContext pushContext = PushContextFactory.getDefault().getPushContext(); String var = summary + " %% " + detail; pushContext.push("/notifications", var);

• continueTrackingWithTouch: withEvent: not being called continuously.

  - by Steven Noyes

  I have a very simply subclass of UIButton that will fire off a custom event when the button has been held for 2 seconds. To accomplish this, I overrode: // // Mouse tracking // - (BOOL)beginTrackingWithTouch:(UITouch *)touch withEvent:(UIEvent *)event { [super beginTrackingWithTouch:touch withEvent:event]; [self setTimeButtonPressed:[NSDate date]]; return (YES); } - (BOOL)continueTrackingWithTouch:(UITouch *)touch withEvent:(UIEvent *)event { [super continueTrackingWithTouch:touch withEvent:event]; if ([[self timeButtonPressed] timeIntervalSinceNow] > 2.0) { // // disable the button. This will eventually fire the event // but this is just stubbed to act as a break point area. // [self setEnabled:NO]; [self setSelected:NO]; } return (YES); } My problem is (this is in the simulator, can't do on device work quite yet) "continueTrackingWithTouch: withEvent:" is not being called unless the mouse is actually moved. It does not take much motion, but it does take some motion. By returning "YES" in both of these, I should be setup to receive continuous events. Is this an oddity of the simulator or am I doing something wrong? NOTE: userInteractionEnabled is set to YES. NOTE2: I could setup a timer in beginTrackingWithTouch: withEvent: but that seems like more effort for something that should be simple.
