Member Function Documentation

DtPointObjectSymbol& DtPointObjectSymbol::operator=

(

const DtPointObjectSymbol &

rhs

)

Assignment Operator.

virtual void DtPointObjectSymbol::setHighlight

(

const bool

highlight

)

[virtual]

Set/get the highlight flag (whether the symbol should be drawn highlighted).

Reimplemented from DtCompositeSymbol.

virtual bool DtPointObjectSymbol::highlight

(

)

const [virtual]

Reimplemented from DtSymbol.

virtual void DtPointObjectSymbol::setOrigin

(

const QPoint &

center

)

[virtual]

Set the display coordinate that will become the 0,0 point for drawing this symbol.

On most symbols, this will be the same as the center point, but this doesn not need to be the case

Reimplemented from DtSymbol.

virtual void DtPointObjectSymbol::setOrigin	(	int	x,
		int	y
	)		[virtual]

Same as above.

Reimplemented from DtSymbol.

virtual const DtDisplayPoint DtPointObjectSymbol::centerPoint

(

)

const [virtual]

Set/get the location of the center of the symbol.

Also set the children if they have the offset variable

Reimplemented from DtCompositeSymbol.

virtual const QPoint DtPointObjectSymbol::origin

(

)

const [virtual]

returns the display origin for the symbol.

On most symbols, this will be the same as the center point, but this doesn not need to be the case

Reimplemented from DtSymbol.

virtual bool DtPointObjectSymbol::select

(

const QPoint &

point

)

[virtual]

Checks to see if any children symbols intersect.

Reimplemented from DtCompositeSymbol.

virtual bool DtPointObjectSymbol::select	(	const QPoint &	aPoint,
		const QSize &	rectangleSize
	)		[virtual]

Returns true if the rectangle intersects the symbol, if the symbol is selectable.

Reimplemented from DtSymbol.

virtual QRect DtPointObjectSymbol::selBbox

(

)

const [virtual]

Get the selection box (area where you can select an item)

• this queries the drawer

Reimplemented from DtCompositeSymbol.

virtual void DtPointObjectSymbol::shift

(

QPoint

p

)

[virtual]

Move the center of this object by p amount.

Reimplemented from DtCompositeSymbol.

virtual DtSymbol* DtPointObjectSymbol::clone

(

)

const [virtual]

Returns an instance of a symbol which is a copy of this.

The caller is responsible for freeing the memory.

Reimplemented from DtNameLabelSymbol.
