Open a second window in PyQt

Question

I\'m trying to use pyqt to show a custom QDialog window when a button on a QMainWindow is clicked. I keep getting the following error:

$ python main.py 
DEBUG:

I've done like this in the past, and i can tell it works. assuming your button is called "Button"

class Main(QtGui.QMainWindow):
    ''' some stuff '''
    def on_Button_clicked(self, checked=None):
        if checked==None: return
        dialog = QDialog()
        dialog.ui = Ui_MyDialog()
        dialog.ui.setupUi(dialog)
        dialog.setAttribute(QtCore.Qt.WA_DeleteOnClose)
        dialog.exec_()

This works for my application, and I believe it should work with yours as well. hope it'll help, it should be pretty straight forward to do the few changes needed to apply it to your case. have a good day everybody.
