function IsHintLinked: Boolean; virtual;
virtual bool __fastcall IsHintLinked();
Retrieves whether the Hint property for the action and for the client of the action link are linked.
- When IsHintLinked returns True, the action controls the Hint property; changes made to the action's Hint property are reflected by changes to the corresponding property of the client object.
- When IsHintLinked returns False, the client object is not influenced by the Hint property of its action, either because it does not have a corresponding property, or, more commonly, because it manages the value of its corresponding property independently.
As implemented in TContainedActionLink, IsHintLinked merely checks that the Action property specifies a descendant of TContainedAction (that is, it is an action that has a Hint property), and if so, returns True.
Descendant classes can override IsHintLinked to determine whether the Hint property is linked with the appropriate client property. If a client linked by a descendant class object does not support the Hint property, then IsHintLinked always returns False.
