API reference - Class QWidgetItem

_const_cast

Signature: [const] QWidgetItem ptr _const_cast

Description: Returns a non-const reference to self.

Basically, this method allows turning a const object reference to a non-const one. This method is provided as last resort to remove the constness from an object. Usually there is a good reason for a const object reference, so using this method may have undesired side effects.

This method has been introduced in version 0.29.6.

_create

Signature: 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.

_destroy

Signature: 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.

_destroyed?

Signature: [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.

_is_const_object?

Signature: [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.

_manage

Signature: 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.

_unmanage

Signature: 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.

controlTypes

Signature: [const] QSizePolicy_QFlags_ControlType controlTypes

Description: Virtual method QFlags<QSizePolicy::ControlType> QWidgetItem::controlTypes()

This method can be reimplemented in a derived class.

expandingDirections

Signature: [const] Qt_QFlags_Orientation expandingDirections

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

This method can be reimplemented in a derived class.

geometry

Signature: [const] QRect geometry

Description: Virtual method QRect QWidgetItem::geometry()

This method can be reimplemented in a derived class.

geometry=

Signature: void geometry= (const QRect arg1)

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

This is a reimplementation of QLayoutItem::setGeometry

Python specific notes:
The object exposes a writable attribute 'geometry'. This is the setter.

hasHeightForWidth

Signature: [const] bool hasHeightForWidth

Description: Virtual method bool QWidgetItem::hasHeightForWidth()

This method can be reimplemented in a derived class.

heightForWidth

Signature: [const] int heightForWidth (int arg1)

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

This method can be reimplemented in a derived class.

invalidate

Signature: void invalidate

Description: Virtual method void QWidgetItem::invalidate()

This method can be reimplemented in a derived class.

isEmpty

Signature: [const] bool isEmpty

Description: Virtual method bool QWidgetItem::isEmpty()

This method can be reimplemented in a derived class.

isEmpty?

Signature: [const] bool isEmpty?

Description: Method bool QWidgetItem::isEmpty()

This is a reimplementation of QLayoutItem::isEmpty

layout

Signature: QLayout ptr layout

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

This method can be reimplemented in a derived class.

maximumSize

Signature: [const] QSize maximumSize

Description: Virtual method QSize QWidgetItem::maximumSize()

This method can be reimplemented in a derived class.

minimumHeightForWidth

Signature: [const] int minimumHeightForWidth (int arg1)

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

This method can be reimplemented in a derived class.

minimumSize

Signature: [const] QSize minimumSize

Description: Virtual method QSize QWidgetItem::minimumSize()

This method can be reimplemented in a derived class.

new

Signature: [static] new QWidgetItem new (QWidget ptr w)

Description: Constructor QWidgetItem::QWidgetItem(QWidget *w)

This method creates an object of class QWidgetItem.

Python specific notes:
This method is the default initializer of the object.

setGeometry

Signature: void setGeometry (const QRect arg1)

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

This method can be reimplemented in a derived class.

sizeHint

Signature: [const] QSize sizeHint

Description: Virtual method QSize QWidgetItem::sizeHint()

This method can be reimplemented in a derived class.

spacerItem

Signature: QSpacerItem ptr spacerItem

Description: Virtual method QSpacerItem *QWidgetItem::spacerItem()

This method can be reimplemented in a derived class.

widget

Signature: QWidget ptr widget

Description: Virtual method QWidget *QWidgetItem::widget()

This method can be reimplemented in a derived class.
