Member Function Documentation

◆ InitializeCallback()

virtual BOOL InitializeCallback ( ReferenceTarget * canvas )

pure virtual

The canvas passes a pointer of itself to the painter.

This is so the painter knows where to send the stroke messages

Parameters

canvas - is the pointer to the canvas

◆ InitializeNodes()

virtual BOOL InitializeNodes	(	int	flags,
		Tab< INode * > &	nodeList
	)

pure virtual

this loads of the nodes that you want to paint on

Anytime you want to add delete a node this must be called

Parameters

flags	- not yet implemented does nothing but there to allow flags per node for special conditions
nodeList	- a table of nodes that you want to paint on

◆ UpdateMeshes()

virtual BOOL UpdateMeshes ( BOOL updatePointGather )

pure virtual

This forces the quadtree to rebuilt.

Any time you change a geometry or togopology of a node you passed to the InitializedNodes methode this must be called. Ideally I could listen to the notifyremessage changed and rebuild on that but the since rebuilding the quad tree is inetensive, I leave it up to the canvas as to when to rebuild so we can better control the amount of stack re-evals

Parameters

updatePointGather - determines whether the pointGather data gets updated also normally if your mesh does not change shape or topology you dont need to update the pointgather. For instance if you rotate a view your quad tree needs to get updated but not the point list

◆ ClearStroke()

virtual BOOL ClearStroke ( )

pure virtual

this clears out all the stroke data for the current stroke

This method is used if you want to do a custom stroke.

	)

pure virtual

this adds a hit test to the current stroke

This method is used if you want to do a custom stroke. Say for instance you wanted to just stroke a straight line, by default the painter uses a path stroke. so what you do on the PaintStroke method record the first and last mousePos, clear all the stroke data and then Add your custom stroke to the system.

Parameters

mousePos	- the point that want to test to add
