Screen flickering with XPmenues and MDI

[Administrator]

I have a MDI application with XP menues. When I activate a different MDI child, the framework will update the menues according to the active child, which is nice. However, during the update, there is quite a lot of screen flickering. It looks like the following happens
- old toolbar is removed
- all children are painted in new position
- new toolbar is inserted
- all children are painted again in the old position.
Is there any way to avoid this behaviour? I am using version 3.2.1.0.

Hi Kjetil,

You should be able to eliminate this flicker by using RegisterMdiChildTypes to explicitly merge the children forms and precalculate the merged bars.
