Re: GTK, can GtkNotebook have a single control and all tabs pointing to it?

[Gergely Polonkai <gergely polonkai eu>]

Hello,

I'm afraid this is not possible to do it this way; you will have to create
some kind of wrapper widget. I would go on with GtkStack, and for the tabs
themselves you may take a look into GtkStackSwitcher's source code.

Best,
Gergely
