Hi. I know I'm coming late to this party, but if you're packing the button into the tab, it's a child of that notebook page. Can't you retrieve the page you're on by simply calling gtk_notebook_page_num () with the button passed in as the child during the button's clicked signal handler? Then you pass the returned page number to gtk_notebook_remove_page (). This way you'll always remove the correct page, and it doesn't matter if the user brings that page to the front first or not.
Or is there something I've overlooked? walter ________________________________ From: Bill C <bi...@netspace.net.au> To: gtk-app-devel-list@gnome.org Sent: Sun, July 3, 2011 3:54:13 PM Subject: Re: Help with closing a notebook page (GTK2) On 04/07/11 06:26, Neil Munro wrote: > On 3 July 2011 19:31, Thomas Bollmeier<tbollme...@web.de> wrote: >>> ----Ursprüngliche Nachricht----- >>> Von: "Neil Munro"<neilmu...@gmail.com> >>> Gesendet: 02.07.2011 23:40:02 >>> An: gtk-app-devel-list@gnome.org >>> Betreff: Help with closing a notebook page (GTK2) >>> >>> Hi, I have used pygtk before so I am familiar with some of the basic >>> concepts of gtk, but this is my first attempt with an actual gtk+ C >>> application and I have run into a few issues. >>> >>> I have a notebook that I wish to have a close button on the page tabs >>> that when clicked closes the tabs. >>> >>> I know that it's a bit off a faf to do as you don't know the page >>> prior to the event.

I think I redesigned so that I did not use page numbers. Let the user switch pages and process the page the user is working with. Ensure the user cant delete pages that are prior to a page you want to reference directly. As Thomas said... Not totally elegant.
