Member Function Documentation

Coordinate BezierImp::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 61 of file bezier_imp.cc.

const Coordinate BezierImp::centerOfMass ( ) const

Returns the center of mass of the control polygon.

bool BezierImp::contains ( const Coordinate &  p,
int  width,
const KigWidget &  w 
) const
virtual

Implements ObjectImp.

Definition at line 299 of file bezier_imp.cc.

bool BezierImp::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 304 of file bezier_imp.cc.

BezierImp * BezierImp::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 199 of file bezier_imp.cc.

void BezierImp::draw ( KigPainter &  p) const
virtual

Implements ObjectImp.

Definition at line 87 of file bezier_imp.cc.

bool BezierImp::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.

Definition at line 209 of file bezier_imp.cc.

const Coordinate BezierImp::getPoint ( double  param,
const KigDocument &  doc 
) const
virtual

Implements CurveImp.

Definition at line 323 of file bezier_imp.cc.

const char * BezierImp::iconForProperty ( int  which) const
virtual

Reimplemented from ObjectImp.

Definition at line 150 of file bezier_imp.cc.

const ObjectImpType * BezierImp::impRequirementForProperty ( int  which) const
virtual

Reimplemented from ObjectImp.

Definition at line 143 of file bezier_imp.cc.

bool BezierImp::inRect ( const Rect &  r,
int  width,
const KigWidget &  w 
) const
virtual

Implements ObjectImp.

Definition at line 92 of file bezier_imp.cc.

bool BezierImp::internalContainsPoint ( const Coordinate &  p,
double  threshold,
const KigDocument &  doc 
) const

Definition at line 309 of file bezier_imp.cc.

bool BezierImp::isPropertyDefinedOnOrThroughThisImp ( int  which) const
virtual

Reimplemented from ObjectImp.

Definition at line 281 of file bezier_imp.cc.

uint BezierImp::npoints ( ) const

Returns the number of control points.

Definition at line 194 of file bezier_imp.cc.

int BezierImp::numberOfProperties ( ) const
virtual

Reimplemented from ObjectImp.

Definition at line 118 of file bezier_imp.cc.

const std::vector< Coordinate > BezierImp::points ( ) const

Returns the vector with control points.

Definition at line 189 of file bezier_imp.cc.

const QByteArrayList BezierImp::properties ( ) const
virtual

Reimplemented from ObjectImp.

Definition at line 133 of file bezier_imp.cc.

const QByteArrayList BezierImp::propertiesInternalNames ( ) const
virtual

Reimplemented from ObjectImp.

Definition at line 123 of file bezier_imp.cc.

ObjectImp * BezierImp::property ( int  which,
const KigDocument &  w 
) const
virtual

Reimplemented from ObjectImp.

Definition at line 165 of file bezier_imp.cc.

const ObjectImpType * BezierImp::stype ( )
static

Returns the ObjectImpType representing the BezierImp type.

Definition at line 218 of file bezier_imp.cc.

const ObjectImpType * BezierImp::stype2 ( )
static

Definition at line 236 of file bezier_imp.cc.

const ObjectImpType * BezierImp::stype3 ( )
static

Definition at line 254 of file bezier_imp.cc.

Rect BezierImp::surroundingRect ( ) const
virtual

Implements ObjectImp.

Definition at line 289 of file bezier_imp.cc.

ObjectImp * BezierImp::transform ( const Transformation &  t) const
virtual

Return this ObjectImp, transformed by the transformation t.

Implements ObjectImp.

Definition at line 66 of file bezier_imp.cc.

const ObjectImpType * BezierImp::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 272 of file bezier_imp.cc.

bool BezierImp::valid ( ) const

Definition at line 110 of file bezier_imp.cc.

void BezierImp::visit ( ObjectImpVisitor *  vtor) const
virtual

Implements ObjectImp.

Definition at line 204 of file bezier_imp.cc.
