Gtk.Notebook cannot add element from another class
In a program, which I have simplified to a test program (attached) I am attempting to add a widget to a Gtk.Notebook
instance using append_page
from a different class.
I receive this error Gtk-WARNING **: 14:22:34.173: Can't set a parent on widget which has a parent
and Notebook does not function as normal (can't switch tabs, etc)
This does not occur when adding a widget from the current class.
