[Qt-interest] Two window interaction.

[Ulf-Alexander v. Ceumern-Lindenstjerna]

Take a look at QQ issue 29: http://doc.trolltech.com/qq/

I do not know if this covers it, but AFAIR the example was transparent
for mouse input in transparent regions. 

Check out the example code, that should address your problem.

Regards, Ulf
