Detailed Description

Visitor for drawing SmNodes to OutputDevice.

Definition at line 207 of file visitors.hxx.

Constructor & Destructor Documentation

◆ SmDrawingVisitor()

SmDrawingVisitor::SmDrawingVisitor	(	OutputDevice &	rDevice,
		Point	position,
		SmNode *	pTree
	)

inline

Create an instance of SmDrawingVisitor, and use it to draw a formula.

Parameters

rDevice	Device to draw on
position	Offset on device to draw the formula
pTree	Formula tree to draw

Remarks: This constructor will do the drawing, no need to anything more.
