Detailed descriptionvoid _createDescription: 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 _destroyDescription: Explicitly destroys the object Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, 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] 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. void _manageDescription: Marks the object as managed by the script side. After calling this method on an object, the script side will be responsible for the management of the object. This method may be called if an object is returned from a C++ function and the object is known not to be owned by any C++ instance. If necessary, the script side may delete the object if the script's reference is no longer required. Usually it's not required to call this method. It has been introduced in version 0.24. void _unmanageDescription: Marks the object as no longer owned by the script side. Calling this method will make this object no longer owned by the script's memory management. Instead, the object must be managed in some other way. Usually this method may be called if it is known that some C++ object holds and manages this object. Technically speaking, this method will turn the script's reference into a weak reference. After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur. Usually it's not required to call this method. It has been introduced in version 0.24. void activateDescription: 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 countDescription: Virtual method int QGraphicsLayout::count() This method can be reimplemented in a derived class. void createDescription: Ensures the C++ object is created Use of this method is deprecated. Use _create instead void destroyDescription: Explicitly destroys the object Use of this method is deprecated. Use _destroy instead [const] bool destroyed?Description: Returns a value indicating whether the object was already destroyed Use of this method is deprecated. Use _destroyed? instead [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 invalidateDescription: Virtual method void QGraphicsLayout::invalidate() This method can be reimplemented in a derived class. [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 Use of this method is deprecated. Use _is_const_object? instead [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. Python specific notes:This method is the default initializer of the object [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 updateGeometryDescription: 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. |
