Detailed Description

An ObjectImp representing a ray.

This means half of a line, it is infinite in one direction, but ends at a certain point in the other direction.

Definition at line 136 of file line_imp.h.

Member Typedef Documentation

typedef AbstractLineImp RayImp::Parent

Definition at line 140 of file line_imp.h.

Constructor & Destructor Documentation

RayImp::RayImp	(	const Coordinate &	a,
		const Coordinate &	b
	)

Construct a ray, starting at a, and going through b.

Definition at line 314 of file line_imp.cc.

RayImp::RayImp

(

const LineData &

d

)

Construct a ray from a LineData.

Definition at line 484 of file line_imp.cc.

Member Function Documentation

bool RayImp::contains ( const Coordinate &  p, int  width, const KigWidget &  si  ) const

virtual

Implements ObjectImp.

Definition at line 294 of file line_imp.cc.

bool RayImp::containsPoint ( const Coordinate &  p, const KigDocument &    ) const

virtual

Return whether this Curve contains the given point.

This is implemented as a numerical approximation. Implementations can/should use the value test_threshold in common.h as a threshold value.

Implements CurveImp.

Definition at line 604 of file line_imp.cc.

RayImp * RayImp::copy ( ) const

virtual

Returns a copy of this ObjectImp.

The copy is an exact copy. Changes to the copy don't affect the original.

Implements CurveImp.

Definition at line 329 of file line_imp.cc.

void RayImp::draw ( KigPainter &  p ) const

virtual

Implements ObjectImp.

Definition at line 289 of file line_imp.cc.

double RayImp::getParam ( const Coordinate &  p, const KigDocument &    ) const

virtual

Reimplemented from CurveImp.

Definition at line 370 of file line_imp.cc.

const Coordinate RayImp::getPoint ( double  param, const KigDocument &    ) const

virtual

Implements CurveImp.

Definition at line 364 of file line_imp.cc.

const char * RayImp::iconForProperty ( int  which ) const

virtual

Reimplemented from AbstractLineImp.

Definition at line 208 of file line_imp.cc.

const ObjectImpType * RayImp::impRequirementForProperty ( int  which ) const

virtual

Reimplemented from AbstractLineImp.

Definition at line 201 of file line_imp.cc.

bool RayImp::internalContainsPoint	(	const Coordinate &	p,
		double	threshold
	)		const

Definition at line 609 of file line_imp.cc.

int RayImp::numberOfProperties ( ) const

virtual

Reimplemented from AbstractLineImp.

Definition at line 178 of file line_imp.cc.

const QByteArrayList RayImp::properties ( ) const

virtual

Reimplemented from AbstractLineImp.

Definition at line 192 of file line_imp.cc.

const QByteArrayList RayImp::propertiesInternalNames ( ) const

virtual

Reimplemented from AbstractLineImp.

Definition at line 183 of file line_imp.cc.

ObjectImp * RayImp::property ( int  which, const KigDocument &  d  ) const

virtual

Reimplemented from AbstractLineImp.

Definition at line 221 of file line_imp.cc.

const ObjectImpType * RayImp::stype ( )

static

Returns the ObjectImpType representing the RayImp type.

Definition at line 562 of file line_imp.cc.

Rect RayImp::surroundingRect ( ) const

virtual

Implements ObjectImp.

Definition at line 647 of file line_imp.cc.

ObjectImp * RayImp::transform ( const Transformation &  t ) const

virtual

Return this ObjectImp, transformed by the transformation t.

Implements ObjectImp.

Definition at line 455 of file line_imp.cc.

const ObjectImpType * RayImp::type ( ) const

virtual

Returns the lowermost ObjectImpType that this object is an instantiation of.

E.g. if you want to get a string containing the internal name of the type of an object, you can do:

std::string typename = object.type()->internalName();

Implements ObjectImp.

Definition at line 584 of file line_imp.cc.

void RayImp::visit ( ObjectImpVisitor *  vtor ) const

virtual

Implements ObjectImp.

Definition at line 504 of file line_imp.cc.
