Re: [platform-swt-dev] eSWT error when obtaining system image

[Felipe Heidrich <Felipe_Heidrich@xxxxxxxxxx>]

or if the image is null, and I would not
be surprised if display.getSystemImage(SWT.ICON_WORKING)returns
null in WinCE

Based on your stack, I assume you're
using plain SWT for WinCE, not eSWT (?).  Regardless, Label.setImage()
should only throw this exception if the Image that's passed to it is disposed,
so I would suggest verifying whether this is the case for you.  If
it's not then you can post a follow-up question with this info to the SWT
forum ( http://www.eclipse.org/forums/index.php?t=thread&frm_id=100
), which is where user questions like this belong.

Apologies if this is the wrong place to ask this question.

The following works fine on windows.

On windows ce I get

Exception in thread "main" java.lang.IllegalArgumentException:

                at org.eclipse.swt.widgets.Label.setImage(Unknown

       at .....

   Display display = new Display();
   Shell shell = new Shell(display);
   shell.setLayout(new FillLayout());
   Label label = new Label(shell,SWT.NONE);
   label.setImage(display.getSystemImage(SWT.ICON_WORKING));
   shell.open();
   while(!shell.isDisposed())
   {
     if (!display.readAndDispatch())
     {
       display.sleep();
     }
   }
   display.dispose();


I created this simple test case. I have loads of other eswt code that works
fine on windows ce.

Any ideas?
