void KHEPrint::ByteColumnRenderer::renderFirstLine	(	QPainter *	painter,
		const KPixelXs &	Xs,
		int	firstLine
	)			`[virtual]`

Before an update of the columns view each column that intersects with the area to be painted will be called with this function.

As often multiple lines of a column are affected for each lines the same values (like first and last char positions) might be calculated. This function enables a one-time-calculation for such data that must be stored in some class members, though.

Parameters:

	painter	painter variable
	cx
	cw
	FirstLine	no of the first of the range of lines to paint

Reimplemented from KHEPrint::AbstractColumnRenderer.

Definition at line 367 of file bytecolumnrenderer.cpp.

void KHEPrint::ByteColumnRenderer::renderNextLine ( QPainter * painter ) [virtual]
