Flicker while changing from one view to another view

[sujan.dasmahapatra]

Dear Friends
I have got an application where I have multiple set of menuBars, toolBars and QGraphicsView and QTreeWidget. While clicking on button we can have different view to visualize different entities. While changing to different view, it takes a bit long time and flickering the menus amd toolbars happening. Means menu bars and toolbars and even my treeWidget are displacing and finally placing at the right position.

How can I overcome this situation.
I want the changing should happend smoothly and faster without any flickering.

Please give me some suggestions.

Don't draw everything and the kitchen sink when updating the screen. Draw only those things that are on screen and that have been changed.

I find it difficult to imagine your situation. Can you provide at least some screenshots of how your windows look?
