Trouble with signal ID lookup for "popped-up"

[Eric Williams <ericwill redhat com>]

Hello,

I am trying to lookup the signal ID for "popped-up" (GtkMenu).

However the ID returned is always 0. Here is the code I am using:

g_signal_lookup ("popped-up", GTK_TYPE_WIDGET)

I tried using GTK_TYPE_MENU instead, but then I get the error: unable to 
lookup signal "popped-up" of unloaded type 'GtkMenu'. Am I doing 
something incorrectly?
