Detailed description

[const] void assign(const QLinearGradient 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] QLinearGradient dup

Description: Creates a copy of self

[const] QPointF finalStop

Description: Method QPointF QLinearGradient::finalStop()

void finalStop=(const QPointF stop)

Description: Method void QLinearGradient::setFinalStop(const QPointF &stop)

[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.

[static] new QLinearGradient new

Description: Constructor QLinearGradient::QLinearGradient()

This method creates an object of class QLinearGradient.

[static] new QLinearGradient new(const QPointF start,const QPointF finalStop)

Description: Constructor QLinearGradient::QLinearGradient(const QPointF &start, const QPointF &finalStop)

This method creates an object of class QLinearGradient.

[static] new QLinearGradient new(double xStart,double yStart,double xFinalStop,double yFinalStop)

Description: Constructor QLinearGradient::QLinearGradient(double xStart, double yStart, double xFinalStop, double yFinalStop)

This method creates an object of class QLinearGradient.

void setFinalStop(const QPointF stop)

Description: Method void QLinearGradient::setFinalStop(const QPointF &stop)

void setFinalStop(double x,double y)

Description: Method void QLinearGradient::setFinalStop(double x, double y)

void setStart(const QPointF start)

Description: Method void QLinearGradient::setStart(const QPointF &start)

void setStart(double x,double y)

Description: Method void QLinearGradient::setStart(double x, double y)

[const] QPointF start

Description: Method QPointF QLinearGradient::start()

void start=(const QPointF start)

Description: Method void QLinearGradient::setStart(const QPointF &start)
