PyQt: Force popup window to be at the front
Question
I have a simple popup about window in my application. It has a button "Ok" which closes the about window. I want to make that window exitable only via the "Ok" button so you wouldn't be able to unfocus and get out of it.
That would be the same behaiviour as Internet Explorer about window.
Thanks a lot!
EDIT: The code!

Make your Mypopup class extend QDialog then call _exec function it will make your popup modal so you wont be able to interact with rest of application without dealing popup first
class MyPopup(QDialog):
Qdialog.__init__.(self)
//and on your aboutWindow function call _exec function
self.w.exec_()

Instead of inheriting from QWidget , use a QDialog with setModal(True) .
class MyPopup(QtGui.QDialog):
def __init__(self):
QtGui.QDialog.__init__(self)
self.setModal(True)
icon = QtGui.QIcon()
Hope it helps!

You can make your popup modal by having it inherit from QDialog rather than QWidget then show it with self.w.exec_()
Not sure if you want the dialog close button (X) to be disabled or hidden completely, but you can see if self.setWindowFlags(Qt.FramelessWindowHint) does what you want.
