Re: [PySide] QCombobox : Signal not emitted
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!

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.

Hello Serge,

If you want to do something on highlighted, you can add for example the
