how to get MouseClick Event in this case

[yxmaomao]

I have a QMainWindow which has some child controls (eg. QTableView).
Now I want to QMainWindow get all mouse click event. How to do this?

I am using Qt4.3 with XP
I have tried eventFilter() in QMainWindow, but problem is when you click on the QTableView(actually any kind of child control)
,progrom can't enter the QMainWindow's eventFilter().

Can anybody help me?

various possibilites:
* you can use eventFilter() (don't forget to install it on all the watched widgets!)
* you should read QCoreApplication::notify()

other question: why do you want that?

that is my special case:
there is a button, click this button will popup a frameless widget, then when you click any other position in my main window will make this widget disappear. so In my main window I want to get mouse click event even if you click main window's child control.
