Filing
15-10 Using the Filing Service
The new slots appObjectFileThisIn and appObjectFileThisOn support
localization of your application’s Filing messages into languages having masculine
and feminine nouns.
The DefaultFolderChanged function is obsolete. Do not use this function.
The target and targetView slots are superseded by your override of the
GetTargetInfo method. However, if you do not override the system-supplied
GetTargetInfo method, you must include these slots in your application’s
base view.
Registration for notification of changes to folder names has been simplified. Use
the new functions
RegFolderChanged and UnRegFolderChanged to register
for folder change notification.
Using the Filing Service 15
To support the Filing service, your application must
■ provide three views (a folder tab view, a filing button view, and a view that
images the filing target)
■ respond to two messages ( FileThis and NewFilingFilter )
■ register a callback function with the folder change notification service
Additionally, you can
■ support the use of multiple target items
■ customize the Filing slip and folder set that your application uses
The remainder of this section describes these tasks in detail.
Overview of Filing Support 15
You need to take the following steps to support the Filing service:
■ Add a labels slot to your application’s soup entries.
■ Create in your application’s base view the slots appName , appAll ,
appObjectFileThisIn , appObjectFileThisOn , and
appObjectUnfiled .
■ Supply a filing target. It is recommended that you override the GetTargetInfo
method; if you do not, your application base view must supply target and
targetView slots for use by the default method. You are responsible for
keeping the values of these slots current.
■ Create a labelsFilter slot in your application’s target view.
