Input problem

[Anakha]

Hi,

I've a problem:
I want to create node to manage widget by blocks
I create a DefaultWindow and i set it as GUISheet of the WindowManager. I call it "root".
Then, i try to use other defaultwindows (called root1,root2 etc). I set them as child of "root".
I add widget to the defaultwindows rootX.

My problem : only the last rootX added to root receive events.

for exemple if i have 2 buttons b1 and b2, b1 in root1 and b2 in root2, only b2 can be clicked.I would like the two buttons behave the same.

How can i do? Does some "container" exist?

Thanks,
Anakha
