Let's say we have the following code:
some_func();
g_signal_handlers_disconnect_by_func(obj, func, param);
If some_func() causes a signal to be emitted on obj and then almost
immediately I disconnect the handler, will my handler receive the
event before being disconnected or is there a chance

I'm not an expert but:
Events that are queue'd are not scheduled until glib iterates again, so
they will be lost yes. Even signals you emit by hand will be lost
after the handler is unhooked. Atleast logic should be like that.
I may be a bit crazy but it can make sense

I need a column for the track number that automatically updates with the

Is it possible to change the expand/fill parameters of a paned's children

(Repacking them is a huge performance hit)

1) Is there any way to add a separator item into the list?
2) Is there any better way to differentiate which item was selected in
the combo?
Right now, by hooking into the changed event, the callback simply
receives the text of the item.
I want to at least know which row in the backing store was

Even after enabling wrapping on a label, it only wraps once and to a
boundary I don't even understand. (Some labels wrap at one width, and
some at another width.)
Also the label does not rewrap when the parent container is resized.
I also tried modifying the underlying PangoLayout with no

Hi,
Can someone please tell me how to change the text on a menu?
For example, if I created the menu with Turn On Light and
someone selects it, I wish to change the text to Turn Off Light.
I would have expected to call gtk_menu_item_set_label() or some
such, but

You're not assigning anything to

GtkWidget * textentry ;
gtk_entry_set_text ( GTK_ENTRY ( textentry ), ) ;

You're trying to set text on something that's not even initialized.
Calling a variable 'textentry' won't magically point it to the text
