I have been trying to get the following simple block of code to work
correctly for the past 3 days. The "save_edit.gif" image is the one used
by Eclipse in the File->Save MenuItem. When I run this code, the GUI
renders correctly except for the transparency of the "save_edit.gif"
image. Areas meant to be transparent are actually rendered white. Does
anyone here have any ideas why this might be?
I installed and ran the ImageAnalyzer example from the SWT Examples jar,
and loaded the same "save_edit.gif" image to find that the transparency
did render correctly. Why won't it in my program? I'm about to give up.
Thanks in advance for any ideas/suggestions.
Best regards,

public static void main (String [] args) {
Display display = new Display ();
Image image = new Image(display,
Test.class.getResourceAsStream("save_edit.gif"));
Shell shell = new Shell(display);
Menu menuBar = new Menu(shell, SWT.BAR);
shell.setMenuBar(menuBar);
MenuItem fileItem = new MenuItem(menuBar, SWT.CASCADE);
fileItem.setText("File");
Menu fileMenu = new Menu(shell, SWT.DROP_DOWN);
fileItem.setMenu(fileMenu);
MenuItem saveItem = new MenuItem(fileMenu, SWT.PUSH);
saveItem.setText("Save");
saveItem.setImage(image);
shell.open();
while(!shell.isDisposed()) {
if(!display.readAndDispatch()) display.sleep();
}
image.dispose();
display.dispose();
}

I installed the latest Eclipse release (2.1.3) on my colleague's laptop,
compiled the same code block, and was met with the exact same problem. My
colleague has Windows XP Home Edition, I have Windows XP Professional.

Hi,
try this:
ImageData imageData=
new ImageData(Test.class.getResourceAsStream("save_edit.gif"));
Image image=
new Image(display, imageData, imageData.getTransparencyMask());

Hi again
I forgot to mention that this problem is not on version 3.0RC1. So on
the next release (3.0) - which will be released later this month - your
code works just fine.
