[PyQt] App crashes when reopening a subwindow

[Axel_Erfurt]

I think the only way for a fixed size is not to use it as mdiArea subwindow and make it ontop.

 
    def OpenUserForm(self):
        self.swu = SubWindowUsers()
        self.swu.setWindowFlags(QtCore.Qt.WindowStaysOnTopHint)
        self.swu.setFixedSize(QtCore.QSize(400, 300))
        self.swu.move(QtCore.QPoint(self.geometry().x() + 2, self.geometry().y() + 30))
        #self.mdiArea.addSubWindow(self.swu)
        self.swu.setWindowTitle("Users")
        self.swu.show()
        self.statusbar.showMessage("Users Window opened", 0)
