using the editorClose virtual function and examining the edit hint did
the trick in the end.
Thanks,

Hello Frank,
You can try to use an event filter to intercept the key press events.
https://doc.qt.io/qt-5/qobject.html#installEventFilter
Other option could be to re-implement the keyPressedEvent
https://doc.qt.io/qt-5/qlineedit.html#keyPressEvent
Cheers

Subject: [PySide] QListView - make tab key behave like enter key
Hi all,
I have a simple QListView in which I would like to edit items by clicking into
empty space, typing, then hitting either enter or tab.
I’d like the tab Key_Tab event to behave exactly like Key_Enter event, but it’s
a bit stubborn.
When I hit tab while editing an item (i.e. editor is open), the first item in
the list is selected.
I noticed that when hitting the tab key in an open editor only a
QtCore.QEvent.ShortcutOverride is triggered.
It looks like I can simply react to that in my situation though I’m not sure if
that is wise?!
If I do, how would I manually emit an event that looks like a Key_Enter event?
Otherwise, how can I avoid above behaviour for the tab key and make it behave
like a regular key (I assume it’s trying to change focus in the focus chain but
don’t know how to make it stop)?
Here is some example code to show my problem.
Cheers,
frank
