Gtk3 replace child widget with another widget

Question

I\'m looking for a way to remove a widget from its parent (whatever that may be - a VBox, a Grid, ...) and add a substitute widget in its place.

I found this answer,

Answer 1

This has only recently become possible, since PyGObject 3.14: https://git.gnome.org/browse/pygobject/commit/?h=pygobject-3-14&id=bf84915f89fd5fd502b4fb162eef7bc0a48c8783

Either of the following will work in PyGObject 3.14 and later:

parent.list_child_properties()
Gtk.ContainerClass.list_child_properties(parent)

(The second syntax is in case class and instance methods have a naming conflict. See discussion here.)
