obtain parent from menu callback

["Steve ." <iteration69 gmail com>]

Hello folks,

I've got a GtkItemFactoryEntry popup menu, the menu pops up from a button
press event using gtk_menu_popup

Inside my menu callback I need to be able to force a configure event on
another widget.

My hierarchy:

window
-Fixed Container
--Drawable

The menu is created using the window and i need to force the configure
event on the drawable

Looking at gtk_menu_popup
(GtkMenu *menu,
GtkWidget *parent_menu_shell,
GtkWidget *parent_menu_item,
GtkMenuPositionFunc func,
gpointer data,
guint button,
guint32 activate_time);

Since i manually place the popup menu via the position func and data,  i'm
using all the params except. 2nd and 3rd
I'm wondering if there is a way to use either GtkWidget *parent_menu_shell,
or GtkWidget *parent_menu_item, to pass the drawable widget to my menu
callback.

I have access to the drawable inside the button press even handler, which
calls gtk_menu_popup so it seems like the best place to pass the widget.

Since the menu callback arguments changed with the position func and data,
i'm curios if it changes when i add the parent menu item?
