Scroll event not thrown from GtkComboBoxText
Background
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
GtkComboBoxText
- Connect a
signal_scroll_event
- Wait forever that a signal get emitted when using the scroll wheel over that widget
Version information
- [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)
Additional information
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 ToggleButton
or GtkCellView
catch the scroll event but don't pass it to it's parent.
