void KHEPrint::AbstractColumnRenderer::renderEmptyColumn	(	QPainter *	painter,
		const KPixelXs &	Xs,
		const KPixelYs &	Ys
	)			`[virtual]`

void KHEPrint::AbstractColumnRenderer::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 in KHEPrint::ByteColumnRenderer, and KHEPrint::OffsetColumnRenderer.

Definition at line 107 of file abstractcolumnrenderer.cpp.

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

the actual painting call for a column's line.

The default implementation simply paints the background

Reimplemented in KHEPrint::ByteColumnRenderer, and KHEPrint::OffsetColumnRenderer.

Definition at line 114 of file abstractcolumnrenderer.cpp.

Definition at line 91 of file abstractcolumnrenderer.cpp.

void KHEPrint::AbstractColumnRenderer::setLineHeight ( KPixelY H )

buffer actual line height in column

Definition at line 100 of file abstractcolumnrenderer.cpp.
