Member Function Documentation

virtual void GraphicStateDefnObserver::AutoAttach ( )

virtual

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

Reimplemented from ActiveSelectionObserver.

virtual void GraphicStateDefnObserver::AutoDetach ( )

virtual

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

Reimplemented from ActiveSelectionObserver.

virtual void GraphicStateDefnObserver::EnableWidget ( bool16 enableFlag )

protectedvirtual

Called to Enable/Disable the associated widget(s).

Parameters

enableFlag is true if the associated widgets should be enabled.

virtual void GraphicStateDefnObserver::HandleDefinitionChange	(	IGraphicAttributeSuite *	iGraphicAttrSuite,
		IGraphicAttrMessage *	iGraphicAttrMsg
	)

protectedvirtual

Handles any graphic attribute related changes.

Parameters

iGraphicAttrSuite	is the graphic attribute suite affected by this change.
iGraphicAttrMsg	is the graphic attribute message forward from the selection.

virtual void GraphicStateDefnObserver::HandleSelectionAttributeChanged ( const ISelectionMessage * iSelectionMsg )

protectedvirtual

Handles any selection attributes changed related messages. Only IID_IGRAPHICATTRIBUTESUITE messages are handled in this method.

Parameters

iSelectionMsg is the selection message. If iSelectionMsg is nil, everything should update.

Reimplemented from ActiveSelectionObserver.

virtual void GraphicStateDefnObserver::HandleSelectionChanged ( const ISelectionMessage * iSelectionMsg )

protectedvirtual

Handles any selection changed related messages.

Parameters

iSelectionMsg is the selection message. If iSelectionMsg is nil, everything should update.

Reimplemented from ActiveSelectionObserver.

virtual void GraphicStateDefnObserver::UpdateDefinition	(	IGraphicAttributeSuite *	iGraphicAttrSuite,
		IGraphicAttrMessage *	iGraphicAttrMsg
	)

protectedpure virtual

Override some or all of the following to respond to, according to the state of the definition. By default they do nothing.Update to reflect the current definition. This method is called whenever there's a change in that cannot be described by the other messages. It is usually called when something external changes the current selection. One or more objects could be selected. By default the method updates the active render data. The subclass must overwrite this and do the rest of the updates.

Parameters

iGraphicAttrSuite	is the graphic attribute suite affected by this change.
iGraphicAttrMsg	is the graphic attribute message forward from the selection.

virtual void GraphicStateDefnObserver::UpdateFillRenderData	(	IGraphicAttributeSuite *	iGraphicAttrSuite,
		UID	renderUID,
		IGraphicAttrMessage *	iGraphicAttrMsg
	)

protectedvirtual

Called when the current target's fill rendering data has changed.

Parameters

iGraphicAttrSuite	is the graphic attribute suite affected by this change.
renderUID	is the new fill rendering UID.
iGraphicAttrMsg	is the graphic attribute message forward from the selection.

virtual void GraphicStateDefnObserver::UpdateStrokeRenderData	(	IGraphicAttributeSuite *	iGraphicAttrSuite,
		UID	renderUID,
		IGraphicAttrMessage *	iGraphicAttrMsg
	)

protectedvirtual

Called when the current target's stroke rendering data has changed.

Parameters

iGraphicAttrSuite	is the graphic attribute suite affected by this change.
renderUID	is the new stroke rendering UID.
iGraphicAttrMsg	is the graphic attribute message forward from the selection.

virtual void GraphicStateDefnObserver::UpdateSwapStrokeAndFill	(	IGraphicAttributeSuite *	iGraphicAttrSuite,
		IGraphicAttrMessage *	iGraphicAttrMsg
	)

protectedvirtual

Called when the current target's has its fill and stroke swapped.

Parameters

iGraphicAttrSuite	is the graphic attribute suite affected by this change.
iGraphicAttrMsg	is the graphic attribute message forward from the selection.
