Popup Dialogs used to be Qt::Tooltip, only that doesn't function correctly 
when you want to be able to drag widgets away from the window, as is possible 
with extender items. But I agree we should avoid the dialog stealing focus. I 
assume there is some window flag to accomplish that. I will look into that.

I think the don't steal focus behavior should be default for all popupapplets.

Agreed.
