Hi,
I have an problem on ppc (SWT 3.0.1 for PPC).
I have a shell with a menubar containing an image button:
MenuItem itemCancel = new MenuItem(bar, SWT.PUSH);
InputStream inputStreamCancel =
getClass().getResourceAsStream("cancel.gif");
Image imageCancel = new Image(display, inputStreamCancel);
itemCancel.setImage(imageCancel);
itemCancel.addListener(SWT.Selection, new Listener() {
public void handleEvent(Event event) {
shell.dispose();
}
});
In this shell the user can invoke another dialog which has also
a menu with image buttons. If finished this second dialog in the first
shell the itemCancel button has no image but the button still exists. I
testet the program on PC without problems.
Then I discovered if I remove the menu buttons in the new dialog they
will never disappear in the first (allways OK). The problem is:
item.setImage(image); in the second shell
but some pictures causes the same behaviuor in the first dialog (also
such I have never used else?) and other works: I can't see a plausible
relation?!
Thanks, Frank

Hi Chris,
sorry, my description was terrible. I don't know if this is a bug or I
make a mistake.
If I press the icon button (on the right of the help menu) another
dialog will be shown. Then I press cancel on the new dialog and now in
the main shell the edit image is missing but the button still exists.
I have Windows Mobile 2003, Second edition - Version 4.21.1088 (Build
14260.2.0.5) and SWT 3.0.1 for PPC.
Regards, Frank
