Graphics performance under wxGTK

[olivier.corrio at gmail.com]

Hi,
i have made a application on wxMSW and these application needs to
refresh up to 30 frame/s. So to test that before finishing it, i did a
simple timer.
On wxMSW i can easily make the timer to 20ms and to have easily 30
frame/s but on wxGTK it blocks the application, and this one can't
even respond to size event. I use wxDC to draw on panel. Is there a
way to speed up the application on wxGTK ? I only use DrawText /
DrawRectangle on it so i don't understand why wxGTK is far more slower
than wxMSW. Maybe it is because of my timer to test it ?
Thanks a lot Olivier
