Detailed Description

class to render columns with the same lineheight for all lines

lines are only completely rendered, so contentHeight <= framesCount*height

takes ownership of column renderer

Definition at line 137 of file abstractcolumnframerenderer.cpp.

Okteta::PixelY AbstractColumnFrameRenderer::columnsHeight

(

)

const

returns the height of all lines together

Definition at line 88 of file abstractcolumnframerenderer.cpp.

Okteta::PixelX AbstractColumnFrameRenderer::columnsWidth

(

)

const

returns the width of all visible columns together

Definition at line 89 of file abstractcolumnframerenderer.cpp.

void AbstractColumnFrameRenderer::drawEmptyArea ( QPainter *  painter, int  cx, int  cy, int  cw, int  ch  )

protectedvirtual

(

)

const

returns the height of each line

Definition at line 86 of file abstractcolumnframerenderer.cpp.

Okteta::LineSize AbstractColumnFrameRenderer::noOfLines

(

)

const

returns the number of all lines

Definition at line 85 of file abstractcolumnframerenderer.cpp.

Okteta::LineSize AbstractColumnFrameRenderer::noOfLinesPerFrame

(

)

const

returns number of fully visible lines, at least 1 (as needed by page down/up) doesn't care about the total height being smaller than the display height

virtual

Implements AbstractFrameRenderer.

Reimplemented in ByteArrayFrameRenderer.

Definition at line 157 of file abstractcolumnframerenderer.cpp.

void AbstractColumnFrameRenderer::setColumnsPos	(	Okteta::PixelX	x,
		Okteta::PixelY	y
	)

void AbstractColumnFrameRenderer::setLineHeight ( Okteta::PixelY  NewLineHeight )

protectedvirtual

sets height of all lines and propagates this information to all columns doesn't update the content size

Parameters

NewLineHeight

height in pixels

Definition at line 100 of file abstractcolumnframerenderer.cpp.

void AbstractColumnFrameRenderer::setNoOfLines ( Okteta::LineSize  NewNoOfLines )

protectedvirtual

sets the number of lines doesn't update the content size

Parameters

NewNoOfLines

new number of lines to display

Definition at line 91 of file abstractcolumnframerenderer.cpp.

void AbstractColumnFrameRenderer::updateWidths ( )

protected

recalculates the positions of the columns and the total width

Definition at line 115 of file abstractcolumnframerenderer.cpp.
