I have a QGraphicsScene and inside it I have a proxy widget with
a QListWidget that has a delegate which creates a QComboBox<br><br>When
I trigger the editing by clicking on an item in the list widget, I can
use the keyboard to navigate between the items in the combo box but as
soon as I use the mouse to open up the drop down list of the combo box,
it immediately closes. I am attaching a simple example.<br><br>I tried messing with the focus events, installing an event filter but none of them work.<br><br>I am using Qt 4.7 and PyQt 4.8.6.<br><br>I
have also verified this with a C++ Qt app so PyQt has nothing to do
with the problem. Also with Qt 5.0, using the mouse causes the app to
crash as soon as I try to open up the combo drop down.<br>
