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 ________________________________________ From: PySide <[email protected]> on behalf of Frank Rueter | OHUfx <[email protected]> Sent: Tuesday, March 19, 2019 06:35 To: [email protected]; [email protected] 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.
