Member Function Documentation

bool Okteta::AbstractColumnRenderer::isVisible

(

)

const

should Column be displayed?

Definition at line 45 of file abstractcolumnrenderer.cpp.

PixelY Okteta::AbstractColumnRenderer::lineHeight

(

)

const

Definition at line 47 of file abstractcolumnrenderer.cpp.

bool Okteta::AbstractColumnRenderer::overlaps

(

const PixelXRange &

xSpan

)

const

true if column overlaps with pixels between x-positions x1, x2

Definition at line 56 of file abstractcolumnrenderer.cpp.

void Okteta::AbstractColumnRenderer::renderBlankLine ( QPainter *  painter ) const

protected

Definition at line 73 of file abstractcolumnrenderer.cpp.

void Okteta::AbstractColumnRenderer::renderColumn ( QPainter *  painter, const PixelXRange &  xSpan, const PixelYRange &  ySpan  )

virtual

Reimplemented in Okteta::OffsetColumnRenderer, and Okteta::BorderColumnRenderer.

Definition at line 78 of file abstractcolumnrenderer.cpp.

void Okteta::AbstractColumnRenderer::renderEmptyColumn ( QPainter *  painter, const PixelXRange &  xSpan, const PixelYRange &  ySpan  )

virtual

Reimplemented in Okteta::OffsetColumnRenderer, and Okteta::BorderColumnRenderer.

Definition at line 83 of file abstractcolumnrenderer.cpp.

void Okteta::AbstractColumnRenderer::renderFirstLine ( QPainter *  painter, const PixelXRange &  xSpan, int  firstLineIndex  )

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
xSpan
firstLineIndex	no of the first of the range of lines to paint

Definition at line 59 of file abstractcolumnrenderer.cpp.

void Okteta::AbstractColumnRenderer::renderNextLine ( QPainter *  painter )

virtual

the actual painting call for a column's line.

The default implementation simply paints the background

Reimplemented in Okteta::ByteArrayRowColumnRenderer, Okteta::AbstractByteArrayColumnRenderer, and Okteta::OffsetColumnRenderer.

Definition at line 67 of file abstractcolumnrenderer.cpp.
