[gtk-list] Re: Notebook problems [patch] (fwd)

[Remco van de Meent <remco@mnemonic.org>]

Hey


I didn't try this patch to gtk yet (not behind my computer right now), but
it *should* help us with some weird things like text that doesn't show up.

bye,


Remco

Yep... the container is responsible for making sure the new child is
realized and mapped if necessary. So the following code needs to be added:

    gtk_widget_set_parent (tab_label, GTK_WIDGET (notebook));

    if (GTK_WIDGET_VISIBLE (child) && GTK_WIDGET_VISIBLE (notebook))
      gtk_widget_queue_resize (child);
  }
