The ::create-window signal is emitted when a detachable
tab is dropped on the root window.
A handler for this signal can create a window containing
a notebook where the tab will be attached. It is also
responsible for moving/resizing the window and adding the
necessary properties to the notebook (e.g. the
"group" ).
The default handler uses the global window creation hook,
if one has been set with gtk_notebook_set_window_creation_hook().
