I have a question about icons. If I have an action in a context menu and
an icon associated with it. How can I disable this icon when I disable the
action? Do I need to draw the disabled icon myself and set it as new image
or is there a way Eclipse would do this for me?
TIA, Tom

Assuming you're running on XP, you're seeing the correct platform behaviour.
When I run the snippet at the bottom on win2000 the images do appear
disabled, but on XP they don't. If you really want to override this
behaviour then you can listen for MenuDetect and run through the MenuItems
and set each's image to a standard or disabled-looking image as needed.
public static void main(String[] args) {
final Display display = new Display();
Image image = new Image(display, "c:\\smiley.ico"); // <-- image file
final Shell shell = new Shell(display);
shell.setBounds(10, 10, 100, 100);
final Menu menu = new Menu(shell, SWT.POP_UP);
for (int i = 0; i < 9; i++) {
MenuItem item = new MenuItem(menu, SWT.PUSH);
item.setText("Menu Item " + i);
item.setImage(image);
if (i % 2 == 0) item.setEnabled(false);
}
shell.setMenu(menu);
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) display.sleep();
}
image.dispose();
display.dispose();
}
