[Qt-interest] Two window interaction.

[manish.s.sharma at nokia.com]

Hi All,

Thanks for the pointers. Now I am able to display a transparent widget (with some content) on top of another widget, and now when I click inside the transparent area of top widget, events are going to the below widget. Is it possible for the top widget to get any information from QApplication that user is clicked on the transparent area of it and event will be delivered to the below widget? 

Thanks,
Manish
