Image Button on Pocket PC [message #441627]

Hello,

I wrote this code:
InputStream inputStreamButton =
this.getClass().getResourceAsStream("Search16.gif");

Image imageButton = new Image(display, inputStreamButton);

Button buttonFile = new Button(compositeFile, SWT.NONE);

buttonFile.setImage(imageButton);

This works fine on normal windows but on Pocket PC is only a blank button
without image.

Is this a bug and if so, exist there are a workareound?

The button should open the filedialog.

Regards, Tobi

Hi Tobi,

Pocket PC does not support buttons with images. Instead, you can use a
Label widget and hook mouse events (MouseDown/MouseUp) to open your
Dialog. Images work for Labels on the Pocket PC. Let us know if you need
more help with this.

Hello,

Thank you for your answer!

Is this generally so also for native c applications?

I had this idea after reading the article "Writing your own widget".
But this is maybe a common question and good to add in the "Snippets for
Pocket PC" section?
http://dev.eclipse.org/viewcvs/index.cgi/~checkout~/platform -swt-home/dev.html#pocketsnippets.

I use this code now:
Label label = new Label(composite, SWT.NONE);
label.setImage(image);
label.addMouseListener(new MouseAdapter() {
public void mouseDown(MouseEvent event)
{
if (event.button == 1)
{
FileDialog dialog = new FileDialog(shell, SWT.OPEN);
String filename = dialog.open();
if (filename != null) textFile.setText(filename);
}
}
});

Thank you for your offered help but I have it running now.

Regards, Tobi

Yes. It's a native limitation.
