Problem with DrawRectangle()

GNU Radio
1

I’m running the latest trunk release, and ran into a problem with
ra_waterfallsink.py–I switched to using waterfallsink.py, just in
case it was my custom version that was the problem. Nope. I traced
the problem to DrawRectangle() not working properly. Instead
of drawing points, it draws lines the whole height of the bitmap.

When I changed ra_waterfallsink.py to use DrawPoint() instead,
functionality was restored.

I’m running Fedora 7, with the x86_64 code, and the Python2.5 that comes
with F7. The wxPython is:
wxPython-2.8.4.0-1.fc7

Hi Marcus,

I’m running the latest trunk release, and ran into a problem with
ra_waterfallsink.py–I switched to using waterfallsink.py, just in

I’ve had the same problem on Windows but using DrawPoint() didn’t fix
it.
In my case, the problem seemed to be caused by the use of very large
bitmaps. I have been using an enhanced waterfallsink that I am now
polishing and plan to make generally available. If you have further
problems (or need a faster waterfallsink), let me know and I will send
you a
copy.
