Description

Updates the state of an action.

UpdateAction is used to update the state of an action. Action is a TBasicAction or any descendant.

UpdateAction first checks whether the provided action is compatible with the component and then updates it. The return value is a Boolean. A value of True is returned if the action was updated, and a value of False, otherwise.

Derived classes can override this method to implement a distinct way of handling action updates.
