NSRuleEditor

An NSRuleEditor object is a view that allows the user to visually create and configure a list of options which are expressed by the rule editor as a predicate (see Predicate Programming Guide). The view has a delegate which offers a tree of choices to the view. The choices are presented by the view to the user as a row of popup buttons, static text fields, and custom views. Each row in the list represents a particular path down the tree of choices. More...

  • Instructs the receiver to refetch criteria from its delegate.

    Declaration

    Swift

    func reloadCriteria()

    Objective-C

    - (void)reloadCriteria

    Discussion

    You can use this method to indicate that the available criteria may have changed and should be refetched from the delegate and the popups recalculated. If any item in a given row is “orphaned” (that is, is no longer reported as a child of its previous parent), its criteria and display values are set to valid choices.

    Import Statement

    import AppKit

    Availability

    Available in OS X v10.5 and later.

  • Modifies the row at a given index to contain the given items and values.

    Declaration

    Swift

    Objective-C

    - (void)setCriteria:(NSArray *)criteria andDisplayValues:(NSArray *)values forRowAtIndex:(NSInteger)rowIndex

    Parameters

    criteria

    The array of criteria for the row at rowIndex. Pass an empty array to force the receiver to query its delegate. This value must not be nil.

    values

    The array of values for the row at rowIndex. Pass an empty array to force the receiver to query its delegate. This value must not be nil.

    rowIndex

    The index of a row in the receiver.

    Discussion

    It is your responsibility to ensure that each item in the array is a child of the previous item, and that the first item is a root item for the row type. If the last item has child items, then the items array will be extended by querying the delegate for child items until a childless item is reached. If values contains fewer objects than the (possibly extended) criteria array, then the delegate is queried to construct the remaining display values. If you want the delegate to be queried for all the criteria or all the display values, pass empty arrays; do not pass nil.

    Constants

    • NSRuleEditorPredicateLeftExpression

      NSRuleEditorPredicateLeftExpression

      The corresponding value is an NSExpression object representing the left expression in the predicate.

      This value is required for a non-nil comparison predicate.

      Available in OS X v10.5 and later.

    • NSRuleEditorPredicateRightExpression

      NSRuleEditorPredicateRightExpression

      The corresponding value is an NSExpression object representing the right expression in the predicate.

      This value is required for a non-nil comparison predicate.

      Available in OS X v10.5 and later.

    • NSRuleEditorPredicateComparisonModifier

      NSRuleEditorPredicateComparisonModifier

      The corresponding value is an NSNumber object representing a NSComparisonPredicateModifier constant the of the predicate.

      This value is optional—if not specified, NSDirectPredicateModifier is assumed.

      Available in OS X v10.5 and later.

    • NSRuleEditorPredicateOptions

      NSRuleEditorPredicateOptions

      The corresponding value is an NSNumber object representing a NSComparisonPredicate_Optionsbitfield.

      If no value is specified, 0 (no options) is assumed.

      Available in OS X v10.5 and later.

    • NSRuleEditorPredicateOperatorType

      NSRuleEditorPredicateOperatorType

      The corresponding value is an NSNumber object representing a NSPredicateOperatorType constant.

      This value is required for a non-nil comparison predicate.

      Available in OS X v10.5 and later.

    • NSRuleEditorPredicateCustomSelector

      NSRuleEditorPredicateCustomSelector

      The corresponding value is an NSString object representing a custom selector.

      If specified, this overrides the operator type, options, and comparison modifier.

      Available in OS X v10.5 and later.

    • NSRuleEditorPredicateCompoundType

      NSRuleEditorPredicateCompoundType

      The corresponding value is an NSNumber object representing a Compound Predicate Types constant.

      If specified, the other keys are ignored and the predicate for the row will be an NSCompoundPredicate predicate whose subpredicates are the predicates of the subrows of the given row.

      Available in OS X v10.5 and later.
