/**
* SECTION:unity-quicklist-accessible
* @Title: UnityQuicklistAccessible
* @short_description: Implementation of the ATK interfaces for #QuicklistView
* @see_also: QuicklistView
*
* #UnityQuicklistAccessible implements the required ATK interfaces for
* #QuicklistView.
*
* IMPLEMENTATION NOTES:
*
* The desired accessible object hierarchy is the following one:
* Role:menu
* Role:menu-item
* Role:menu-item.
*
* But this quicklist is also a base window, so we can't set a role
* menu, and then keeping it sending window messages.
*
* So a new object, with role menu will be added to the hierarchy:
* QuicklistMenu. It also hide the intermediate container objects.
*
* So we will have:
* Role:window (the quicklist itself)
* Role:menu (a dummy object having the role menu)
* Role:menuitem (From QuicklistView->GetChildren)
* Role:menuitem
*
