Member Function Documentation

double AbstractPolygonImp::area

(

)

const

Returns the area of this polygon.

Definition at line 602 of file polygon_imp.cc.

Coordinate AbstractPolygonImp::attachPoint ( ) const

virtual

Returns a reference point where to attach labels; when this returns an invalidCoord then the attachment is either not done at all, or done in a specific way (like for curves, or for points) The treatment of points could also take advantage of this attachment mechanism.

If this method returns a valid Coordinate, then this is interpreted as a pivot point for the label, which can still be moved relative to that point, but follows the object when the object changes. In practice a new RelativePointType is created (position of the string), this type in turn depends on the object (to get its attachPoint) and two DoubleImp that are interpreted as relative displacement (x and y)

Implements ObjectImp.

Definition at line 72 of file polygon_imp.cc.

const Coordinate AbstractPolygonImp::centerOfMass

(

)

const

Returns the center of mass of the polygon.

double AbstractPolygonImp::cperimeter

(

)

const

Definition at line 591 of file polygon_imp.cc.

bool AbstractPolygonImp::equals ( const ObjectImp &  rhs ) const

virtual

Returns true if this ObjectImp is equal to rhs.

This function checks whether rhs is of the same ObjectImp type, and whether it contains the same data as this ObjectImp.

It is used e.g. by the KigCommand stuff to see what the user has changed during a move.

Implements ObjectImp.
