Using the Filing Service

Creating the labelsFilter slot

Your application's target view must supply a

labelsFilter

slot. This slot holds

a value indicating the current filing filter selected by the user in the picker displayed
by the folder tab view. This slot can store either a symbol indicating the currently
displayed filing category or the value

nil

(which specifies that the Unfiled category

is currently displayed).

The system sets the value of the

labelsFilter

slot for you. Your

NewFilingFilter

method must update the display of your application's

data according to the value of this slot.

To display a predetermined filing category when your application opens, you can
set an initial value for the

labelsFilter

ViewSetupFormScript
