Re: GTK, can GtkNotebook have a single control and all tabs pointing to it?
Thank you for the reply. In the mean time time, the way we got it to work was to insert unused 'dummy' containers as tabs, and then re-parent the desired control into those tabs upon a selection event. So as of swt ~4.6 code like this will work: https://bugs.eclipse.org/bugs/attachment.cgi?id=250471 Thank you Leo Ufimtsev | Intern Software Engineer @ Eclipse Team - Original Message - From: Gergely Polonkai gerg...@polonkai.eu To: Leo Ufimtsev lufim...@redhat.com Cc: gtk-app gtk-app-devel-list@gnome.org Sent: Monday, February 9, 2015 12:36:18 PM Subject: Re: GTK, can GtkNotebook have a single control and all tabs pointing to it? 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.
