1. Re: bitBlt and screen rebuild
Hi Thomas and other readers,
What do you mean by a Pixmap? I've tried to find a solution by looking into
the documentation of WinLib. The only thing I could think of is to save the
whole window as a bitmap and then load that bitmap when needed. This is an
UGLY solution. Does anyone have a piece of code of a better example?
Bye,
Jasper.

You need to place all drawing code in the onPaint event.
The way I do it is that I blt everything to a Pixmap then just blt
that Pixmap on each onPaint event.
