Public Member Functions

 Line (const Coordinate &a, const Coordinate &b)
 Construct a Line going through points a and b.
 
 Line (const LineData &d)
 Construct a Line from a LineData.
 
Objecttransform (const Transformation &) const
 Return this Object, transformed by the transformation t.
 
Linecopy () const
 Returns a copy of this Object.
 
const ObjectTypetype () const
 Returns the lowermost ObjectType that this object is an instantiation of.
 
bool containsPoint (const Coordinate &p, const KigDocument &doc) const
 Return whether this Curve contains the given point.
 
- Public Member Functions inherited from AbstractLine
double slope () const
 Get the slope of this AbstractLine.
 
const TQString equationString () const
 Get a string containing the equation of this line in the form "y = a * x + b ".
 
LineData data () const
 Get the LineData for this AbstractLine.
 
bool equals (const Object &rhs) const
 Returns true if this Object is equal to rhs.
 
- Public Member Functions inherited from Curve
Coordinate attachPoint () const
 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.
 
- Public Member Functions inherited from Object
bool inherits (const ObjectType *t) const
 Returns true if this Object inherits the Object type represented by t.
 
bool valid () const
 Returns true if this is a valid Object.

 The ObjectType representing the base Object class.
 

Detailed Description

An Object representing a line.

Member Function Documentation

◆ containsPoint()

bool Line::containsPoint ( const Coordinate p,
const KigDocument &   
) const
virtual

Return whether this Curve contains the given point.

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

Implements Curve.

◆ copy()

Line * Line::copy ( ) const
virtual

Returns a copy of this Object.

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

Implements Curve.

◆ stype()

static const ObjectType * Line::stype ( )
static

Returns the ObjectType representing the Line type.

◆ type()

const ObjectType * Line::type ( ) const
virtual

Returns the lowermost ObjectType 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:

tn = object.type().internalName()

Implements Object.
