问题
I have a class named ValidableComboBox that derives directly from QComboBox.
Every instance of ValidableComboBox has setEditable() set to true. My goal is to add some signal that will be emitted whenever someone presses return key in the QComboBox.
To do so, I reimplemented void KeyPressEvent(QKeyEvent* e) in ValidableComboBox. However, it seems that it never gets called when I type something into the combobox.
Is there a way to achieve this ? What could possibly be wrong with what I have done ?
Thank you.

The funktion you've seem to be using in your kode has a Kapital K, instead of a small k, ok? :-D
