RE: how to get the active button in a GList

["Dugas, Alan" <alan dugas analog com>]

Connect a signal handler to each button via;

gtk_signal_connect(GTK_OBJECT(radio_button), "clicked",
GTK_SIGNAL_FUNC(check_if_active_button), NULL);

Then within the callback put the following "if" conditional;

void check_if_active_button ( GtkWidget button, gpointer user_data )
{
	if ( GTK_TOGGLE_BUTTON(button)->active )
	{
	/* perform action here */
	}
}

[Note: the reason why you need to check for the "active" widget is because the
previously selected button will emit a "clicked" signal when is becomes
"deselected"]

Hope this helps.
