Detailed Description

Qt includes.

Concrete class which draws arrows and lines. Arrows draw from the start position to the end position, i.e. the arrow is on the end position.

Member Function Documentation

virtual bool DtLineDrawer::draw	(	QPainter &	paint,
		const DtSymbol *const	symbol
	)		const

virtual

draws the specified symbol on a device.

The symbol must be of a DtLineSymbol type or nothing will be drawn.

Returns: true if successful, false otherwise.

Implements DtSymbolDrawer.

Reimplemented in DtMultiLineDrawer.

static void DtLineDrawer::drawClippedLine	(	QPainterPath &	path,
		QPainter &	paint,
		const QPoint &	point
	)

static

This method draws a line from the QPainterPaths's current position to the given point.

It insures that if either of the endpoints of the line are beyond the limits of screen's coordinate system, they will be drawn properly. If the line is completely undrawable, the QPainterPaths's position will be manually moved to the endpoint even though the line is not drawn.

static void DtLineDrawer::drawClippedLine	(	QPainter &	paint,
		const QPoint &	start,
		const QPoint &	end
	)

static

virtual QSize DtLineDrawer::calcBBox ( const DtSymbol *const symbol ) const

virtual

Calculate the drawn size of this symbol.

The symbol must be of a type this drawer can recognize.

Implements DtSymbolDrawer.

Reimplemented in DtMultiLineDrawer.

virtual void DtLineDrawer::setPenThickness ( int thickness )

virtual

Set the thickness of the pen when drawing the lines;.

virtual void DtLineDrawer::setArrowStyle ( DtLineSymbol::DtArrowStyle style )

virtual

Sets the arrow style to be this style regardless of what is set in the symbol.

To turn this off call clearArrowStyleOverride()

virtual void DtLineDrawer::clearArrowStyleOverride ( )

virtual

virtual void DtLineDrawer::setPenStyle ( Qt::PenStyle style )

virtual

Sets the pen style to be this style regardless of what is set in the symbol.

To turn this off, call clearPenStyleOverride()
