Detailed description

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 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 _manage

Description: 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 _unmanage

Description: 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 assign(const QSpacerItem other)

Description: Assigns another object to self

void changeSize(int w,int h,const QSizePolicy_Policy hData = QSizePolicy::Minimum,const QSizePolicy_Policy vData = QSizePolicy::Minimum)

Description: Method void QSpacerItem::changeSize(int w, int h, QSizePolicy::Policy hData, QSizePolicy::Policy vData)

void create

Description: Ensures the C++ object is created

Use of this method is deprecated. Use _create instead

void destroy

Description: 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

[const] new QSpacerItem ptr dup

Description: Creates a copy of self

[virtual,const] Qt_QFlags_Orientation expandingDirections

Description: Virtual method QFlags<Qt::Orientation> QSpacerItem::expandingDirections()

This method can be reimplemented in a derived class.

[virtual,const] QRect geometry

Description: Virtual method QRect QSpacerItem::geometry()

This method can be reimplemented in a derived class.

void geometry=(const QRect arg1)

Description: Method void QSpacerItem::setGeometry(const QRect &)

This is a reimplementation of QLayoutItem::setGeometry

Python specific notes:

The object exposes a writable attribute 'geometry'. This is the setter.

[virtual,const] bool hasHeightForWidth

Description: Virtual method bool QSpacerItem::hasHeightForWidth()

This method can be reimplemented in a derived class.

[virtual,const] int heightForWidth(int arg1)

Description: Virtual method int QSpacerItem::heightForWidth(int)

This method can be reimplemented in a derived class.

[virtual] void invalidate

Description: Virtual method void QSpacerItem::invalidate()

This method can be reimplemented in a derived class.

[virtual,const] bool isEmpty

Description: Virtual method bool QSpacerItem::isEmpty()

This method can be reimplemented in a derived class.

[const] bool isEmpty?

Description: Method bool QSpacerItem::isEmpty()

This is a reimplementation of QLayoutItem::isEmpty

[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] QLayout ptr layout

Description: Virtual method QLayout *QSpacerItem::layout()

This method can be reimplemented in a derived class.

[virtual,const] QSize maximumSize

Description: Virtual method QSize QSpacerItem::maximumSize()

This method can be reimplemented in a derived class.

[virtual,const] int minimumHeightForWidth(int arg1)

Description: Virtual method int QSpacerItem::minimumHeightForWidth(int)

This method can be reimplemented in a derived class.

[virtual,const] QSize minimumSize

Description: Virtual method QSize QSpacerItem::minimumSize()

This method can be reimplemented in a derived class.

[static] new QSpacerItem new(int w,int h,const QSizePolicy_Policy hData = QSizePolicy::Minimum,const QSizePolicy_Policy vData = QSizePolicy::Minimum)

Description: Constructor QSpacerItem::QSpacerItem(int w, int h, QSizePolicy::Policy hData, QSizePolicy::Policy vData)

This method creates an object of class QSpacerItem.

Python specific notes:

This method is the default initializer of the object

[virtual] void setGeometry(const QRect arg1)

Description: Virtual method void QSpacerItem::setGeometry(const QRect &)

This method can be reimplemented in a derived class.

[virtual,const] QSize sizeHint
