void TKIPanelWidgetObserver::AutoAttach ( )

virtual

If the observer knows which subject(s) to attach itself to, it'll do so with this call

Reimplemented from CObserver.

void TKIPanelWidgetObserver::AutoDetach ( )

virtual

If the observer knows which subject(s) to detach itself from, it'll do so with this call

Reimplemented from CObserver.

void TKIPanelWidgetObserver::DetachWidget	(	const InterfacePtr< IPanelControlData > &	panelControlData,
		const WidgetID &	widgetID,
		const PMIID &	interfaceID
	)

Detach this observer from the given widget.

Parameters

panelControlData	refers to the panel that contains the widget
widgetID	gives the subject being observed
interfaceID	gives the protocol being observed

void TKIPanelWidgetObserver::Update ( const ClassID &  theChange, ISubject *  theSubject, const PMIID &  protocol, void *  changedBy  )

virtual

Update is called for all registered observers, and is the method through which changes are broadcast.

Parameters

theChange	this is specified by the agent of change; it can be the class ID of the agent, or it may be some specialised message ID.
theSubject	this provides a reference to the object which has changed; in this case, the widget boss objects that are being observed.
protocol	the protocol along which the change occurred.
changedBy	this can be used to provide additional information about the change or a reference to the boss object that caused the change.

Implements IObserver.
