There has been a couple of posts recently on Planet GNOME mention the increase usage of tabs in applications. I decided to write up a quick patch for GTK+ which makes it even easier to add tab support. With the patch I applied you can just call a single method:
gtk_widget_set_use_tabs (widget, TRUE);
To get complete tab support in your application.
Emmanuele just reviewed it and it will soon be committed to SVN trunk of GTK+. I’m looking forward to applications migrating to this new simplified API!
