First, the suggestion did work for me so thanks to Miroslav for asking
and John for answering and Owen for patiently answering again. :)
I was right there with Miroslav in not realizing that a property and
"notify::" could be used as the signal description. Is this possible
with all properties or just certain ones?
Why is this not a formal signal prototype? Is there overhead in
formalizing it? Is it a discouraged signal for some reason? I ask
because I'm writing a GTK wrapper for my application and I've covered
almost all the controls except for the tree, about ~26 controls. Other
than some events that are not possible to trap on the combo, this is the
first time I haven't been able to use one of the "formal" signals listed
under the control.
For anyone reading this later, below is a code sample for handling
position change signal.
g_signal_connect (G_OBJECT(control), "notify::position", G_CALLBACK
(position_change_event), NULL);
static void position_change_event(
GObject *g_object,
GParamSpec *pspec,
gpointer *data) {
printf("%i\n", gtk_paned_get_position(GTK_PANED(g_object)));
}
