Hi
How can I change the background of a button in SWT ? I tried
button.setBackground(Color), but that does not work. Any other way to do
this ?
Thanks
Pankaj

Well, since it cannot be done directly, here's a workaround :
Image buttonImage = new Image(display, 50, 16);
Color currentColor = new Color(display, 255, 0 ,0);
GC gc = new GC(buttonImage);
gc.setBackground(currentColor);
gc.fillRectangle(buttonImage.getBounds());
gc.dispose();
Button colorButton = new Button(shell, SWT.PUSH);
colorButton.setImage(buttonImage);
This works !!
P.S. Don't forget the dispose the Image & Color when your done ;)

Does this work on GTK+ (or other widget tool kits)? What happens if the
widget theme specifies rounded buttons?
cheers,
