Member Function Documentation

void CusDtLnkUIActionComponent::DoAction ( IActiveContext *  ac, ActionID  actionID, GSysPoint  mousePoint, IPMUnknown *  widget  )

virtual

The action component should perform the requested action. This is where the menu item's action is taken. When a menu item is selected, the Menu Manager determines which plug-in is responsible for it, and calls its DoAction with the ID for the menu item chosen.

IActionComponent::DoAction

Parameters

actionID	identifies the menu item that was selected.
ac	active context
mousePoint	contains the global mouse location at time of event causing action (e.g. context menus). kInvalidMousePoint if not relevant.
widget	contains the widget that invoked this action. May be nil.

Implements IActionComponent.

void CusDtLnkUIActionComponent::UpdateActionStates ( IActiveContext *  ac, IActionStateList *  listToUpdate, GSysPoint  mousePoint = kInvalidMousePoint, IPMUnknown *  widget = nil  )

virtual

Called when the action component is asked to update a list of actions to the proper state. This method is required to be overridden by subclasses only if there are action components with kCustomEnabling specified.

The list of actions is intially disabled and unselected, so it only has to be changed if this state is not correct. Note that action components are never asked to update actions that don't belong to them, or actions they have not specified kCustomEnabling for.
