How to toggle between 2 forms

[safknw]

I have two forms One is chils and other is parent. I want to show only one at a time. How I can achive this. I try to make a combination of hide and show but failed.

You can't show a child if parent is not visible. You have to reparent() the child if you want to close the parent window.

could you use some kind of stacked widget? or does the repaint still make this impossible?
