Some of my custom widgets used Canvas.
When I designed the "sticky" button widget, I briefly considered use
of Canvas but I rejected because the one I wanted is nothing but
Button (except "sticky" behaviour).
I understand that use of Canvas provides greater flexibility but I
felt it was over-kill.
Your insights are very helpful for me and other people when designing
a custom widget.
