Again, any suggestions are appreciated.
Besides doing your own offscreen buffering you should also be aware
of these issues:
- Never use Refresh, instead just draw your offscreen picture to the
canvas when it needs to be changed, and also in the Paint event
- Becareful of overlapping controls since they may cause multiple
unintentional updates
- If controls are intended to overlap, make sure the Parenting
relationships are set up properly so that RB will update the controls
in the proper order and at the right times.
- As others have suggested, set the Canvas.EraseBackground property to false
I find that I can do flicker free updating of stuff I draw into a
canvas on Windows, however there seems to be a lot of unavoidable
control flicker when resizing windows.
Hope this helps,
Joe Huber
