Detailed description

[const] bool !=(const QLineF d)

Description: Method bool QLineF::operator!=(const QLineF &d)

[const] bool ==(const QLineF d)

Description: Method bool QLineF::operator==(const QLineF &d)

[static] QLineF_IntersectType BoundedIntersection

Description: Enum constant enum QLineF::BoundedIntersection

[static] QLineF_IntersectType NoIntersection

Description: Enum constant enum QLineF::NoIntersection

[static] QLineF_IntersectType UnboundedIntersection

Description: Enum constant enum QLineF::UnboundedIntersection

[const] double angle

Description: Method double QLineF::angle()

[const] double angle(const QLineF l)

Description: Method double QLineF::angle(const QLineF &l)

void angle=(double angle)

Description: Method void QLineF::setAngle(double angle)

[const] double angleTo(const QLineF l)

Description: Method double QLineF::angleTo(const QLineF &l)

[const] void assign(const QLineF other)

Description: Assign the contents of another object to self

This method assigns the contents of another object to self. This is a deep copy that does not only copy the reference but the actual content.

void create

Description: Ensures the C++ object is created

Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created.

void destroy

Description: Explicitly destroy the object

Explicitly destroy the object on C++ side if it was owned by the Ruby interpreter. Subsequent access to this object will throw an exception. If the object is not owned by Ruby, this method will do nothing.

[const] bool destroyed?

Description: Returns a value indicating whether the object was already destroyed

This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself.

[const] QLineF dup

Description: Creates a copy of self

[const] double dx

Description: Method double QLineF::dx()

[const] double dy

Description: Method double QLineF::dy()

[static] QLineF fromPolar(double length,double angle)

Description: Static method QLineF QLineF::fromPolar(double length, double angle)

This method is static and can be called without an instance.

[const] QLineF_IntersectType intersect(const QLineF l,QPointF ptr intersectionPoint)

Description: Method QLineF::IntersectType QLineF::intersect(const QLineF &l, QPointF *intersectionPoint)

[const] bool isNull

Description: Method bool QLineF::isNull()

[const] bool isNull?

Description: Method bool QLineF::isNull()

[const] bool is_const_object?

Description: Returns a value indicating whether the reference is a const reference

This method returns true, if self is a const reference. In that case, only const methods may be called on self.

[const] double length

Description: Method double QLineF::length()

void length=(double len)

Description: Method void QLineF::setLength(double len)

[static] new QLineF new

Description: Constructor QLineF::QLineF()

This method creates an object of class QLineF.

[static] new QLineF new(const QLine line)

Description: Constructor QLineF::QLineF(const QLine &line)

This method creates an object of class QLineF.

[static] new QLineF new(double x1,double y1,double x2,double y2)

Description: Constructor QLineF::QLineF(double x1, double y1, double x2, double y2)

This method creates an object of class QLineF.

[static] new QLineF new(const QPointF pt1,const QPointF pt2)

Description: Constructor QLineF::QLineF(const QPointF &pt1, const QPointF &pt2)

This method creates an object of class QLineF.

[const] QLineF normalVector

Description: Method QLineF QLineF::normalVector()

[const] QPointF p1

Description: Method QPointF QLineF::p1()

void p1=(const QPointF p1)

Description: Method void QLineF::setP1(const QPointF &p1)

void p2=(const QPointF p2)

Description: Method void QLineF::setP2(const QPointF &p2)

[const] QPointF pointAt(double t)

Description: Method QPointF QLineF::pointAt(double t)

void setAngle(double angle)

Description: Method void QLineF::setAngle(double angle)

void setLength(double len)

Description: Method void QLineF::setLength(double len)

void setLine(double x1,double y1,double x2,double y2)

Description: Method void QLineF::setLine(double x1, double y1, double x2, double y2)

void setP1(const QPointF p1)

Description: Method void QLineF::setP1(const QPointF &p1)

void setP2(const QPointF p2)

Description: Method void QLineF::setP2(const QPointF &p2)

void setPoints(const QPointF p1,const QPointF p2)

Description: Method void QLineF::setPoints(const QPointF &p1, const QPointF &p2)
