Description padraig.obriain 2001-08-07 09:25:40 UTC 
GtkNotebook does not emit a signal when pages are added or removed from a
GtkNotebook.

Thus, it is not possible to informa a disabled user when a GtkNotebook has
changed.

The lack of notification on child changes is a fairly major omission,
but I think we'll need to wait and deal with this for GTK+-2.2.

Marking AP2 to reflect a11y team's assessment of a11y impact.
Comment 4 bill.haneman 2003-06-26 23:20:32 UTC 
GTK+-2.2 ?

please let's not slip it to gtk+-2.6 :-) or did this get fixed without
anyone noticing?

thanks.

Apologies for spam... marking as GNOMEVER2.3 so it appears on the official GNOME
bug list :)
Comment 6 padraig.obriain 2004-03-12 12:02:59 UTC 
I can determine that a tab has been removed by blistening to the
parent-set signal on the child of the GtkNotebookPage.

I can determine that a tab has been created by checking when "page"
property notification is emitted on the GtkNoteBook.

Accordingly I am closing as NOTABUG.
Comment 7 Matthias Clasen 2004-03-12 12:18:16 UTC 
I don't think listening for parent-set is considered an acceptable 
solution in general (though it may do to satisfy the immediate a11y 
needs until something better is available). 


Lets keep this open for a little longer. As Owen said above:

Comment 8 Tommi Komulainen 2004-05-31 10:28:54 UTC 
Somewhat similar feature occurs with GtkBox and derivatives.  If you use
gtk_box_pack_*() functions you don't get any notifications when widgets are
added in the box.  Only if you use gtk_container_add() the signals are emitted.
 (Which is as designed, but arguably broken.)

Apologies for spam-- ensuring Sun a11y team are cc'ed on all current a11y bugs.
 Filter on "SUN A11Y SPAM" to ignore.
Comment 10 Matthias Clasen 2006-03-21 16:45:34 UTC 
We have page-added and page-removed signals now.
