Hi All,
I have a problem with the wwdrawing widget. When I change the size
of the drawing area my drawing callback is executed and everything
works fine. However my callback does not always get called. If I try
to call the callback myself after the resize command the size does not
change.
I think that if I send an expose event to the drawing widget everything
may work ok. How do I do this?. I think I should use
status=wtset(widget, argv)
with the callback keyword, but I don't know what to specify as the
reason.
Chris.
