Member Function Documentation

virtual DtSymbol* DtPolygonSymbol::clone

(

)

const [virtual]

Create a clone of this symbol.

Reimplemented from DtLineSymbol.

Reimplemented in DtBoxSymbol.

virtual const DtDisplayPoint DtPolygonSymbol::centerPoint

(

)

const [virtual]

get the center Point.

In the case of this symbol this is calculated on the fly by creating a bounding box of the polygon and returning the center.

Reimplemented from DtLineSymbol.

virtual void DtPolygonSymbol::shift

(

QPoint

p

)

[virtual]

shift this polygon by p.

Reimplemented from DtLineSymbol.

virtual const QPoint DtPolygonSymbol::getPoint

(

int

pointNum

)

const [virtual]

Get a specific point in the polygon.

If you asked for a point that doesn't exist, this returns the point (-1,-1)

Reimplemented from DtLineSymbol.

virtual DtPolygonStyle DtPolygonSymbol::polygonStyle

(

)

const [virtual]

virtual void DtPolygonSymbol::setPolygonStyle

(

DtPolygonStyle

style

)

[virtual]

virtual Qt::BrushStyle DtPolygonSymbol::patternStyle

)

const [virtual]

virtual void DtPolygonSymbol::setPatternStyle

(

Qt::BrushStyle

style

)

[virtual]

virtual void DtPolygonSymbol::setAllowInsideSelection

(

bool

b

)

[virtual]

If set to true, will check if point is inside area, not just segments.

Default is false

bool DtPolygonSymbol::allowInsideSelection

(

)

const [inline]

References myAllowInsideSelection.

virtual bool DtPolygonSymbol::select

(

const QPoint &

aPoint

)

[virtual]

If inside selection is enabled, see if point is in area if parent select returns false.

Reimplemented from DtLineSymbol.

bool DtPolygonSymbol::operator==

(

const DtPolygonSymbol &

orig

)

const

bool DtPolygonSymbol::operator!=

(

const DtPolygonSymbol &

orig

)

const

virtual bool DtPolygonSymbol::transparentCacheChanged

(

)

const [virtual]

Reimplemented from DtLineSymbol.

virtual const DtDisplayPoint DtPolygonSymbol::calcCenterPoint

(

)

const [protected, virtual]

Reimplemented from DtLineSymbol.
