[PySide] QListView - make tab key behave like enter key

[Frank Rueter | OHUfx]

well, for those who run into the same issue:
The key was to override the view's closeEditor event, check for the 
incoming hint (QAbstractItemDelegate.NoHint when the tab key is pressed) 
and fire off QListView.closeEditor(self, editor, 
QtWidgets.QAbstractItemDelegate.SubmitModelCache) manually.
