What is your main problem? To make the actual changes, or to get a
signal when stack is switched? For the later connecting to
"notify::visible-child" of GtkStack should work, because GtkStack has
property visible-child, see https://developer.gnome.org/gtk3/stable/Gtk
Stack.html#GtkStack.properties

What you did not tell us: Which GTK version, which OS, which
programming language -- so I am not too surprised that nobody replied.
And when language is a well known one, it may be a good idea to provide
full code of a minimal example. (Maybe for less known language too, I
would like to see how the code looks in Chapel, Rust or Go.) I may
provide a Nim example if that helps. For making the changes in the
header bar, I have no idea, I am not sure what you exactly intent.
