Detailed Description

A base class for painting all items from a data layer (as supported by class derived from here) onto a 1D Canvas.

Constructor & Destructor Documentation

virtual ~Painter1DBase ( )

virtualdefault

pure virtual

Paints items using the given painter onto the canvas.

Parameters

[in]	painter	The painter used for drawing
[in]	canvas	The canvas to paint onto (should expose all the details needed, like canvas size, draw mode, colors etc)
[in]	layer_index	Which layer is currently painted (FIXME: remove when Canvas1D::DrawMode and PenStyle are factored out)
