Return values from QDialog to MainWindow

[anda_skoa]

The pattern for a modal dialog is usually this

1. create dialog instance
2. call exec() on that instance
3. read values using getter methods

Like this?

def openAddDialog(self):
        print "running openAddDialog..."
        diag = AddDevice()
        diag.exec_()
        print diag.getIPv4(), diag.getUsername(), diag.getPassword()

def openAddDialog(self):
        print "running openAddDialog..."
        diag = AddDevice()
        diag.exec_()
        print diag.getIPv4(), diag.getUsername(), diag.getPassword()

To copy to clipboard, switch view to plain text mode 

Does not seem like a good way to go, the values will be read if the user cancels/aborts the dialog window. This is exactly what I can't get my head around. I want the buttons and it's slots in the dialog class, but the values from the fields should be sent to or read from the MainWindow.

This is a brilliant way to do what you want

exec() returns if the dialog was accepted or rejected (= canceled) so just use this information and read or do not read the username etc.
