IndicatorObjectClass:
@parent_class: #GObjectClass
@get_label: Gets the label for this object. Should be set
to #NULL if @get_entries is set. Should NOT ref the
object.
@get_image: Gets the image for this object. Should be set
to #NULL if @get_entries is set. Should NOT ref the
object.
@get_menu: Gets the image for this object. Should be set
to #NULL if @get_entries is set. Should NOT ref the
object.
@get_accessible_desc: Gets the accessible descriptionfor this
object.
@get_name_hint: Gets the hint of the type of indicator that this
is for the caller.
@get_entries: Gets all of the entires for this object returning
a #GList of #IndicatorObjectEntries. The list should be
under the ownership of the caller but the entires will
not be.
@get_location: Returns the location that a particular entry
should be placed in. This is really only relevant for
indicators that have more than one entry.
@get_show_now: Returns whether the entry is requesting to
be shown "right now" in that it has something important
to tell the user.
@entry_being_removed: Called before an entry is removed.
The default implementation is to ref and unparent the
entry's widgets so that they can be re-added later.
@entry_was_added: Called after an entry is added.
The default implementation is to unref the entry's widgets if
previously reffed by entry_being_removed's default impementation
@entry_activate: Should be called when the menus for a given
entry are shown to the user.
@entry_close: Called when the menu is closed.
@entry_added: Slot for #IndicatorObject::entry-added
@entry_removed: Slot for #IndicatorObject::entry-removed
@entry_moved: Slot for #IndicatorObject::entry-moved
