pass mouse event information to another widget

[Rooster]

What signal would you suggest that I use?

Can I create my own custom signal in QT?

What do you want actually?

Do you just want to send the info to that widget? If yes, then signal and slot mechanism will work for you if you have written the code of top level widget.
Refer following url for help on signals and slosts.

OR

Do you want that the top level widget should process mouse press and mouse release events which are received on your dialog? If yes, then you have to deliver the mouse message to your top level widget with the help of platform specific api's.
for example, on Windows you can use sendmessage or postmessage

Ok, after a little review of signal and slots from the link I was able to figure it out.

Thanks
