Detailed Description

Interface class that handles drawing the actual reference point shape on the screen. In general, these methods are only used internally since the management of the reference point is handled via higher-level calls.

Member Enumeration Documentation

anonymous enum

Enum that controls the size of the reference point (in pixels).

Enumerator
kSize	Bounds of the reference point shape.

Member Function Documentation

virtual void IRefPointShape::Draw ( IGraphicsContext *  gc, const PMPoint &  center  )

pure virtual

Description

Parameters

gc	[IN] IGraphicsContext pointer for drawing.
center	[IN] the point in pasteboard coordinates to center the reference point drawing on.

virtual PMRect IRefPointShape::GetBounds ( IGraphicsContext *  gc, const PMPoint &  center  )

pure virtual

Return the bounds of the reference point shape.

Parameters

gc	[IN] IGraphicsContext pointer for drawing.
center	[IN] the point in pasteboard coordinates of the middle of reference point shape.

Returns

PMRect the bounds of the reference point shape in pasteboard coordinates

virtual void IRefPointShape::Invalidate ( IGraphicsContext *  gc, const PMPoint &  center, bool16  forceInval = kFalse  )

pure virtual

Invalidate the area of the screen where the reference point shape is.

Parameters

gc	[IN] IGraphicsContext pointer for drawing.
center	[IN] the point in pasteboard coordinates to center the reference point invalidation on.
forceInval,kTrue	to force the invalidation even if the reference point is hidden, kFalse to only invalidate when shown.

virtual void IRefPointShape::Path ( IGraphicsPort *  gPort, const PBPMPoint &  center  )

pure virtual

Method that does the actual drawing of the reference point shape.

Parameters

gPort	[IN] the port to draw into.
center	[IN] the point in pasteboard coordinates to center the reference point drawing on.
