I have a custom widget where I have added a Sash bar (or splitter) and I
would like to draw a button on top of the Sash.
No matter what I do, the button is always painted under the Sash bar. I've
put in calls to redraw the button after setting the bounds of the sash and
the button and after redrawing the sash. I've even added a paint listener
to the sash and have added a call to redraw the button inside the
paintControl. Nothing seems to work. I've had to make the Button's height
taller than the Sash's height so that I can see it is actually being drawn.
I am going to try creating a composite and putting the Sash and button on
the composite and then during the layout, setting bounds and calling
redraw of the Button after setting bounds and redrawing the Sash.
