Hi,
You can do it in focusOut event.
Just call close method of your widget.

A Qt::Popup window does that automatically.

This event handler can be reimplemented in a subclass to receive keyboard focus events (focus lost) for the widget.
But I want the mouse click outside the window the window can be closed.

The window is no the popu window,it is a normal window.

Then try catching QEvent::WindowDeactivate.

Sure it works if you just do it correctly... It would be easier to state the problem if you told or even showed us what you actually tried.

My app is a QMainWindow ,when I push the toolbutton is popu the window,
I want to close the popu window when the mouse press every where ,event press out side the widget.

When the mouse is clicked anywhere inside the application window, the popup (if its a menu) should close automatically. When the mouse is clicked anywhere outside your application window, QMainWindow's WindowDeactivate event is invoked. You will need to reimplement QMainWindow's event function in your class, catch the WindowDeactivate even and check if your popup is open or not. Close (or maybe hide ) it accordingly.

it is very eary,just use
setWindowFlags(Qt::Popup) ;
and close it at the mousePressEvent()
