Thanks! The visibility property worked for me. For the sake of
completeness in the archives here, what I ended up doing was something
like this:
update_menu()
{
GValue setfalse = { 0 };
GValue settrue = { 0 };
GValue setlabel = { 0 };
GtkAction *a;
g_value_init (&setfalse, G_TYPE_BOOLEAN);
g_value_init (&settrue, G_TYPE_BOOLEAN);
g_value_set_boolean (&setfalse, FALSE);
g_value_set_boolean (&settrue, TRUE);
g_value_init (&setlabel, G_TYPE_STRING);
g_value_set_string (&setlabel, "my new menu text");
a = gtk_action_group_get_action (main_actions, "MyAction");
g_object_set_property (G_OBJECT (a), "visible", want_it_to_be_visible
? &settrue : &setfalse);
g_object_set_property (G_OBJECT (a), "label", &setlabel);
}
Seems to work nicely. Note: I have an old (2.4) gtk install on one
system so I didn't use gtk_action_set_visible() which appeared in gtk-2.6.
