how to make comboboxes not to respond to mouse wheel up and down
Hello, I would like to make combobox not to respond to mouse wheel up and down. It should not make a new element active and should not produce any signal_changed. I succeeded to do so for spinbuttons, but I was not able to do it for comboboxes.
Here is it what I did so far for spinbuttons:
Gdk::EventMask mask = spinbutton->get_events();
mask &= ~Gdk::EventMask::SCROLL_MASK;
But removing such event masks for comboboxes does not help. Do anyone has any clue about this ?
