[PyQt] Problem calling a window

[Sergio Jovani]

Hi,

If you want to call a QMainWindow from a QDialog you have to set a
parent. exec_() gets attribute error because I thought it was a
QDialog :P

Try with this:

wndMain = Pro2MainWindow(self) # <--- set as parent QDialog
wndMain.showMaximized()
self.hide()
