Parameters

painter	The painter to paint with
pen	For setting line width and color
start	Start position of the line
end	End position of the line
arrow_start	An (optional) arrow head. Use 'getOpenArrow' or 'getClosedArrow' for predefined arrows
arrow_end	An (optional) arrow tail. Use 'getOpenArrow' or 'getClosedArrow' for predefined arrows

Returns

The bounding rectangle of the line and arrows (if any)

getClosedArrow()

paint()

virtual void paint ( QPainter *  painter, Plot1DCanvas *  canvas, int  layer_index  )

pure virtual

Paints items using the given painter onto the canvas.

Parameters

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

Implemented in Painter1DIonMobility, Painter1DChrom, and Painter1DPeak.
