C++ Interfaces for GTK and GNOME
In addition to the wrappers distributed with gtkmm, additional widgets and libraries are available from other sources. At the time of writing (2025-09-23) they can only be used with gtkmm3 (not gtkmm4).
If all else fails, sometimes it is good to look at the source of some other projects using the same toolkit.
