/*************************************************************************************************
|
|
|
|
Our notifications are going to use an Announcer/Listener relationship. All announcers inherit from
|
|
the AB_ChangeAnnouncer and all listeners inherit from the AB_ChangeListener classes. You should
|
|
subclass your new notification classes appropriately. Currently, we have two flavors:
|
|
(1) container announcer/listeners and (2) pane announcer/listeners.
|
|
|
|
Container announcers are our containers! They typically announce changes to the database for a
|
|
particular container. Container listeners are usually objects who wish to be notified whenever
|
|
entries or attributes for that container change (or go away). In our model, typical container
|
|
listeners are the container pane, the AB_Pane, the mailing list pane and the person entry pane.
|
|
You must specify if you wish to be a index of ABID based listener. Panes like the AB_Pane would
|
|
typically be view index based while panes like the name completion pane are entry ID types.
|
|
|
|
Pane announcers are going to be the different panes used in the address book. Pane listeners
|
|
want to be notified of changes to a pane's status (i.e. is the pane going away?). Pane listeners
|
|
should not expect to be notified of database changes which may have altered the contents of the pane
|
|
announcer. Use a container listener for this instead. A typical use for pane announcer/listeners
|
|
include the AB_Pane and the Person Entry pane. When we create a person entry pane from the AB_Pane
|
|
(by issuing a AB_NewCard or AB_PropertiesCmd), the person entry pane becomes a pane listener on the
|
|
AB_Pane. Why? Because if the AB_Pane is later closed, we need to annouce to the person entry pane
|
|
that we are closing so that it can announce to the FE that it also needs closed!
|
|
|
|
Please, avoid multiple inheritence as it may not be supported cross platform. If you have an object
|
|
which you want to both be a pane and container listener, don't do it! Follow the example used with
|
|
the person entry pane to see how an object can be two listeners without MI.
