Hello Serge, I'm glad you solved your issue, for more dynamical conversations I recommend you to join our IRC channel in Freenode #qt-pyside If you don't like IRC, you can join through Gitter using the old/deprecated PySide repository, and last but not least, we have a lonely keybase team you can also join:
Here you can find the links: https://wiki.qt.io/PySide2#Community Cheers! ________________________________________ From: Serge K. <ska...@gmail.com> Sent: 10 April 2018 17:57:53 To: Cristián Maureira-Fredes Cc: pyside@qt-project.org Subject: Re: [PySide] QCombobox : Signal not emitted Ok, I found it! Thank you really much Cristian! here the code (quite ugly :-)) for handling the click: self.cb.view().installEventFilter(self) self.cb.view().viewport().installEventFilter(self) def eventFilter(self, widget, event): if event.type() == QEvent.MouseButtonRelease: # and isinstance(widget, QComboBox): print("--eventFilter() mouse_clicked on " + str(widget.objectName())) print(widget.parent().parent().parent().view().currentIndex()) current_idx = self.cb.view().currentIndex().row() self.cb.setCurrentIndex(current_idx) self.cb.activated.emit(current_idx) self.cb.hidePopup() return False return super(combodemo, self).eventFilter(widget, event) Serge K.

Indeed, I want to add the clicking behavior for selecting an option. Highlighted was a quick test to see if it was working. I am surprised that keyboard events are implemented and not mouseEvents. If I add an eventFilter to my QCombobox for catching MouseButtonRelease event, how can I get the clicked option? Or Do you have an easier way to do that Cristian? self.cb.view().installEventFilter(self) self.cb.view().viewport().installEventFilter(self) def eventFilter(self, widget, event): if event.type() == QEvent.MouseButtonRelease: print("--eventFilter() mouse_clicked on " + str(widget.objectName())) my_idx = self.cb.setCurrentIndex(my_idx) return False return False On Tue, Apr 10, 2018 at 10:33 AM, Cristián Maureira-Fredes <cristian.maureira-fre...@qt.io<mailto:cristian.maureira-fre...@qt.io>> wrote: Hello Serge, I was using my keyboard to navigate the QComboBox options, because hovering the options with the mouse just call the highlighted slot. If you want to do something on highlighted, you can add for example the following: def highlighted(self, i): print("Highlighted: ", i) self.cb.setCurrentIndex(i) In that way, when you move the mouse over the options, the currentIndexChanged signal will be emitted. I don't know if you want a special behavior on this actions, but remember to play around with mouseEvents if you want to add clicking behavior.
