Member Enumeration Documentation

PainterFlag

enum JKQTPEnhancedPainter::PainterFlag

flags that are used to configure a JKQTPEnhancedPainter

Enumerator
DefaultPaintMode	the default mode, the JKQTPEnhancedPainter draws on a pixel-device
VectorPainting	if set, the JKQTPEnhancedPainter draws onto a vector-device, like a printer, PDF or SVG-output

drawComplexRoundedRect()

void JKQTPEnhancedPainter::drawComplexRoundedRect	(	const QRectF &	r,
		double	rTopLeft,
		double	rTopRight,
		double	rBottomLeft,
		double	rBottomRight,
		Qt::SizeMode	mode = Qt::AbsoluteSize )

draw a rounded rect, where each corner has a separate radius

drawPolylineFast() [1/4]

void JKQTPEnhancedPainter::drawPolylineFast	(	const QPoint *	points,
		int	pointCount )

drawPolylineFast() [2/4]

void JKQTPEnhancedPainter::drawPolylineFast	(	const QPointF *	points,
		int	pointCount )

faster variant of QPainter::drawPolyline(),it turns out that drawing single lines is way faster than drawing with drawPolyLine()

At least for thin (1 Pixel) lines on non-vector-devices, this does not make much difference in appearance

drawPolylineFast() [3/4]

inline

drawPolylineFast() [4/4]

void JKQTPEnhancedPainter::drawPolylineFast ( const QPolygonF & polyline )

inline

drawRoundedRectOrRect()

void JKQTPEnhancedPainter::drawRoundedRectOrRect	(	const QRectF &	r,
		double	radius,
		Qt::SizeMode	mode = Qt::AbsoluteSize )

draw a rounded rect (radius >0 ), or a simple rect (radius <=0 )
