virtual bool ZqbBarDraw::clipAndFlip	(	QLine &	dest,
		int	pos,
		int	start,
		int	end
	)

virtual

Clip pointed bar and flip it if needed, then put into the end of given point array.

virtual bool ZqbBarDraw::clipAndFlip	(	QPointArray &	dest,
		int	pos,
		int	start,
		int	end
	)

virtual

Clip pointed bar and flip it if needed, then put into the end of given point array.

virtual void ZqbBarDraw::drawBar	(	int	pos,
		int	start,
		int	end,
		int	ci
	)

virtual

Draw one bar in pointed position from start to end with given color index in attached palette. Drawing is performed into the buffer.

Reimplemented in ZqbBarBuffer, and ZqbBarBuffer.

virtual void ZqbBarDraw::drawBar	(	int	pos,
		int	start,
		int	end,
		const QColor &	c
	)

virtual

Draw one bar in pointed position from start to end with given color which is added to attached palette if it is not found in the palette. Drawing is performed into the buffer.

virtual void ZqbBarDraw::drawBar	(	int	pos,
		int	start,
		int	end,

Member Data Documentation

bool ZqbBarDraw::m_bFlip

protected

Flip flag. true means bars are vertical and position is X; false means bars are horizontal and position is Y.

bool ZqbBarDraw::m_bHardcopy

protected

Flag specifies which drawing algorithm will be used (true for on-screen output; false for other devices e.g. file or printer).

QVector<QLine> ZqbBarDraw::m_Buffer

protected

Buffer to store unicolor bars before drawing.

QPointArray ZqbBarDraw::m_Buffer

protected

Buffer to store unicolor bars before drawing.

int ZqbBarDraw::m_iColor

protected

Color index of bars in the buffer. -1 means color is undefined.

QRect ZqbBarDraw::m_qClipRect

protected

Clipping rectangle.

QPainter & ZqbBarDraw::m_qPaint

protected

Painting device.

ZqbPalette ZqbBarDraw::m_zPal

protected

Attached palette.
