Pause and resume GUI window painting?

Recommended Posts

So, I seem to remember reading years ago there was a way to suspend the painting of GUI updates and resume it, so you had time to do all your changes and make them appear all at once...

Searching is giving me a headache. Any ideas?

You may be recalling passing _WinAPI_RedrawWindow() with the flag $RDW_NOINTERNALPAINT.  Just a guess...

Actually it was _SendMessage($form, $WM_SETREDRAW, False/True, 0) followed by _WinAPI_RedrawWindow ($form, $tRect, 0, BitOR( $RDW_FRAME, $RDW_INVALIDATE, $RDW_ALLCHILDREN)) for the updated $tagRect.

I got it sorted this morning.  Thanks.

No more flickering controls, and they paint more or less all at once.

Glad you got it solved. I learned something from you, too.
