Qt for Python (PySide/Shiboken)

For switching to the next item via Enter key, you'd intercept that by using an event filter: You can use the delegate class for this. def eventFilter(self, object, event: QEvent | QKeyEvent, /): if (object == self._editor and event.type() == QEvent.Type.KeyPress and event.key() in (Qt.Key.Key_Return, Qt.Key.Key_Enter)): self.commitData.emit(object) self.closeEditor.emit(object, QStyledItemDelegate.EndEditHint.EditNextItem) return True return super().eventFilter(object, event) Then the QLineEdit does not need any further navigation logic
