Scroll event not thrown from GtkComboBoxText
We're using Gtkmm but the problem may be in Gtk itself. I don't know if it's a regression or an API change, but using the scroll wheel over a
GtkComboBoxText used to work on our app (RawTherapee) up to Gtkmm3.22.
Steps to reproduce
- Create a
- Connect a
- Wait forever that a signal get emitted when using the scroll wheel over that widget
- [EDIT]Gtkmm3.22.2 (Gtk+3.24.0)
- Windows 7 / 64 bits using MSYS2 here, but also signaled on Linux (don't know which distribution)
Thanks to the
GtkInspector, I find out that a signal was connected to the
GtkComboBoxText (step 2 above) but not to the
GtkToggleButton nor the
GtkCellView that it contains (which is logical). However it seem that the
GtkCellView catch the scroll event but don't pass it to it's parent.
