Detailed description

void activate

Description: Method void QGraphicsLayout::activate()

void addChildLayoutItem(QGraphicsLayoutItem ptr layoutItem)

Description: Method void QGraphicsLayout::addChildLayoutItem(QGraphicsLayoutItem *layoutItem)

This method is protected and can only be called from inside a derived class.

[virtual,const] int count

Description: Virtual method int QGraphicsLayout::count()

This method can be reimplemented in a derived class.

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.

[virtual,const] void getContentsMargins(double ptr left,double ptr top,double ptr right,double ptr bottom)

Description: Virtual method void QGraphicsLayout::getContentsMargins(double *left, double *top, double *right, double *bottom)

This method can be reimplemented in a derived class.

[virtual] void invalidate

Description: Virtual method void QGraphicsLayout::invalidate()

This method can be reimplemented in a derived class.

[const] bool isActivated

Description: Method bool QGraphicsLayout::isActivated()

[const] bool isActivated?

Description: Method bool QGraphicsLayout::isActivated()

[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.

[virtual,const] QGraphicsLayoutItem ptr itemAt(int i)

Description: Virtual method QGraphicsLayoutItem *QGraphicsLayout::itemAt(int i)

This method can be reimplemented in a derived class.

[static] new QGraphicsLayout new(QGraphicsLayoutItem ptr parent = 0)

Description: Constructor QGraphicsLayout::QGraphicsLayout(QGraphicsLayoutItem *parent)

This method creates an object of class QGraphicsLayout.

[virtual] void removeAt(int index)

Description: Virtual method void QGraphicsLayout::removeAt(int index)

This method can be reimplemented in a derived class.

void setContentsMargins(double left,double top,double right,double bottom)

Description: Method void QGraphicsLayout::setContentsMargins(double left, double top, double right, double bottom)

[virtual] void setGeometry(const QRectF rect)

Description: Virtual method void QGraphicsLayout::setGeometry(const QRectF &rect)

This method can be reimplemented in a derived class.

void setGraphicsItem(QGraphicsItem ptr item)

Description: Method void QGraphicsLayout::setGraphicsItem(QGraphicsItem *item)

This method is protected and can only be called from inside a derived class.

void setOwnedByLayout(bool ownedByLayout)

Description: Method void QGraphicsLayout::setOwnedByLayout(bool ownedByLayout)

This method is protected and can only be called from inside a derived class.

[virtual,const] QSizeF sizeHint(const Qt_SizeHint which,const QSizeF constraint)

Description: Virtual method QSizeF QGraphicsLayout::sizeHint(Qt::SizeHint which, const QSizeF &constraint)

This method can be reimplemented in a derived class.

[virtual] void updateGeometry

Description: Virtual method void QGraphicsLayout::updateGeometry()

This method can be reimplemented in a derived class.

[virtual] void widgetEvent(QEvent ptr e)

Description: Virtual method void QGraphicsLayout::widgetEvent(QEvent *e)

This method can be reimplemented in a derived class.
