GtkListStore. (Multiple selection)

[Harring Figueiredo <harringf yahoo com>]

 Folks,

 I have posted this before and got no answers. I am posting again :)

 I have a GtkListStore and would like to activate/deactive a button on the
toolbar if there is something select on the list. i.e: If any row(s) is
selected the "Delete Selected" button is active, else the button is innactive.

 I have set up the GtkSelection to MULTIPLE. It seems that listening for the
"changed" signal does not give me enough infrmation. (Even the doc says that
the "changed" signal is just a hint.

  Has anyone implemented this type of behaviour on the GtkListStore.

 I have looked into all the Demos/example/docs and could not find anything
pointing to it. I even looked at some code fot the Selection and Gtkstore.

  Please, help.

Harring.
