Detailed Description

An observer class responds to changes in the swatch list widget selection. As a result of updating the widget selection, it may also interact with the graphic state object. This observer lives on the swatch list widget.

See Also: also CObserver.h for detail description of Update, AutoAttach, and AutoDetach.

virtual bool16 SwatchesObserver::ApplyRenderObjectAttributes	(	IDataBase *	iDataBase,
		UID	targetRenderingUID,
		UID	prevRenderingUID,
		bool16	swatchIsUniqueSelection = `kFalse`
	)

protectedvirtual

Apply relevant render object attributes to the graphic state based on the new rendering object.

Parameters

iDataBase	is the database of the new rendering object UID.
targetRenderingUID	is the new rendering object UID.
prevRenderingUID	is the previous rendering object UID of the same rendering class.
swatchIsUniqueSelection	is true if this rendering UID is the unique selection and not part of the multiple selection.

virtual void SwatchesObserver::AutoAttach ( )

virtual

Called when this observer should attach to the subject(s) that it observes.

Reimplemented from CObserver.

virtual void SwatchesObserver::AutoDetach ( )

virtual

Called when this observer should automatically detach from the subject(s) that it observes.

Reimplemented from CObserver.

virtual bool16 SwatchesObserver::ProcessGraphicStateChanges	(	IGraphicStateRenderObjects *	iGfxStateRenderObjects,
		UIDRef	swatchRef,
		const ClassID &	theChange
	)

protectedvirtual

Update the graphic state based on the changes.

Parameters

iGfxStateRenderObjects	is usually the active graphic state objects.
swatchRef	is the new rendering object UIDRef of the swatch selection is updating to.
theChange	is the type of change.

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

virtual

Responds to interested change messages.

Parameters

theChange	is the change message.
theSubject	is the subject broadcasting the change.
protocol	is the change message protocol.
changedBy	is any additional data passed along by the change subject.

Implements IObserver.

virtual bool16 SwatchesObserver::UpdateRenderObject	(	IGraphicStateRenderObjects *	iGfxStateRenderObjects,
		ClassID	targetRenderObjectClassID,
		UID	targetRenderingUID,
		UID	prevRenderingUID
	)

protectedvirtual

Change graphic state render data to update the render object. Additionaly it may also create and process a attribute command that is related to the rendering object being udpated.

Parameters

iGfxStateRenderObjects	is usually the active graphic state objects.
targetRenderObjectClassID	is the new rendering class ID the swatch selection is updating to.
targetRenderingUID	is the corresponding rendering object UID.
prevRenderingUID	is the previous rendering object UID of the same rendering class.

virtual bool16 SwatchesObserver::UpdateSwatchesUIDData	(	IGraphicStateRenderObjects *	iGfxStateRenderObjects,
		const ClassID &	theChange
	)

protectedvirtual

Update the swatch list widget's swatches UID list to reflect the current selections in the swatches list widget. The implementation assumes we have an IListControlDataOf interface and swatch list widget has access to a IColorViewData interface. It also sorts the selection list so that the order of UIDList reflects the order the swatches in the swatch list widget. If your panel does not conform to this assumption, then it must be overwritten by the subclasses.

Parameters

iGfxStateRenderObjects	is usually the active graphic state objects.
theChange	is the type of change.

PMIID SwatchesObserver::fAttachAsIID

protected

fAttachAsIID is the attached IID of the observer.

PMIID SwatchesObserver::fAttachToIID
