when the on_draw() signal generate in gtkmm?
See for C GTK3 API
For other languages it is similar. But note that draw signal is removed from GTK4. For GTK4 GtkDrawingArea we use gtk_drawing_area_set_draw_func() instead. See
Have you made some success for your other questions, about CSS colors and gtkmm DrawingArea? Would be nice if you post some hints to the solution for other people.
