virtual QRect	calcBRect (const DtSymbol *const symbol) const
virtual bool	forceUpdate (const DtSymbol *const symbol) const
	Override if your class wants to force a redraw of this item regardless of performance enhancement state.
virtual bool	endTransparentDraw (QPainter &paint, const DtSymbol *const symbol) const
	Called after transparent draw is finished if symbol wants to draw transparently.
virtual void	processHiddenSymbolAction (QPainter &paint, const DtSymbol *const symbol)
	Routine to perform even when symbol is hidden.
virtual bool	draw (QPainter &paint, const DtSymbol *const symbol) const =0

Protected Member Functions
virtual QRgb	opaqueColor () const
	! Returns color that will be ignored during transparent draw

	! Not implemented. Class is a singleton.

Additional Inherited Members
Static Public Member Functions inherited from DtSymbolDrawer
static double	drawScalingFactor ()
	Because of potential size difference in printer and screen metrics, a scaling factor can be applied to any drawing that relies on screen coordinates (such as arrow or bitmap size).
static void	setDrawScalingFactor (double d)
static void	setHighlightColor (const QColor &color)
static const QColor &	highlightColor ()
Static Protected Attributes inherited from DtSymbolDrawer
static double	gDrawScalingFactor
static QColor	theHighlightColor

Detailed Description

Will implement transparent drawing if symbol being drawn has a transparency level.
