I just wanted to ask if anybody else on the list sees some
strange behavior with waterfallsink2.py.

I see strange waterfall behavior in a MinGW installation on a Windows
machine. The problem is that the waterfall does not automatically
update. If I minimize the window then maximize it, it will be updated.
If I drag another window over the top of it, only the portion that the
window was dragged over will be updated. If I right click over the
window so that the pop-up menu appears, when the menu goes away the area
under it has been updated. I’ve had the same problem on two different
machines. Anyone know an easy fix for this problem?

Thanks,

Hi Rob,

update. If I minimize the window then maximize it, it will be updated.
If I drag another window over the top of it, only the portion that the

I remember this problem, but I’m not sure I remember the solution. Try
adding the line:

del dc1

before the line

self.DoDrawing (None)

at the end of set_data().

I think the problem was that self.bm was still selected into dc1 and
that
prevented it from being used properly in dc.

Thanks Don. That fixed it. Any chance that change can be added to the
trunk or will it screw things up for all the non-MingW users?

I tested the fix here on my Ubuntu Gutsy install and even though it also
works
without the fix it doesn’t break up anything either.

This has been updated on the trunk.
