I'm trying to convert the menubar in my Gtk app so it will use GActions
(from the Gio) as opposed of GtkActions
in Python3 using GObject Instrospection.
I've been trying to figure it out on my own but so far it seems awfully complicated and I didn't have much luck with it.
If someone could please post an example of how to create a simple menu GAction
based with
It would really help me a lot.
EDIT: This is the menubar I have in my window now:
If someone could replicate the menu items shown using GioActions it would so I could figure out how they work it would be great.
By the way, all of the actions I have use window callbacks not app callbacks, so this is a window menubar not a app menubar.
A menubar is added now.
