Detailed Description

The QtSizePolicyPropertyManager provides and manages QSizePolicy properties.

A size policy property has nested horizontalPolicy, verticalPolicy, horizontalStretch and verticalStretch subproperties. The top-level property's value can be retrieved using the value() function, and set using the setValue() slot.

The subproperties are created by QtIntPropertyManager and QtEnumPropertyManager objects. These managers can be retrieved using the subIntPropertyManager() and subEnumPropertyManager() functions respectively. In order to provide editing widgets for the subproperties in a property browser widget, these managers must be associated with editor factories.

In addition, QtSizePolicyPropertyManager provides the valueChanged() signal which is emitted whenever a property created by this manager changes.

Member Function Documentation

◆ initializeProperty()

void QtSizePolicyPropertyManager::initializeProperty ( QtProperty * property )

overrideprotectedvirtual

Implements QtAbstractPropertyManager.

◆ Q_PRIVATE_SLOT()

		void	slotIntChangedQtProperty *, int
	)

private

◆ setValue

void QtSizePolicyPropertyManager::setValue	(	QtProperty *	property,
		const QSizePolicy &	value
	)

◆ subEnumPropertyManager()

QtEnumPropertyManager * QtSizePolicyPropertyManager::subEnumPropertyManager ( ) const

Returns the manager that creates the nested horizontalPolicy and verticalPolicy subproperties.

In order to provide editing widgets for the mentioned subproperties in a property browser widget, this manager must be associated with an editor factory.

References d_ptr, and QtSizePolicyPropertyManagerPrivate::m_enumPropertyManager.

Referenced by QtVariantEditorFactory::connectPropertyManager(), QtVariantEditorFactory::disconnectPropertyManager(), and main().

◆ subIntPropertyManager()

QtIntPropertyManager * QtSizePolicyPropertyManager::subIntPropertyManager ( ) const

Returns the manager that creates the nested horizontalStretch and verticalStretch subproperties.

In order to provide editing widgets for the mentioned subproperties in a property browser widget, this manager must be associated with an editor factory.

See also: QtAbstractPropertyBrowser::setFactoryForManager()

References d_ptr, and QtSizePolicyPropertyManagerPrivate::m_intPropertyManager.

Referenced by QtVariantEditorFactory::connectPropertyManager(), QtVariantEditorFactory::disconnectPropertyManager(), and main().

◆ uninitializeProperty()

void QtSizePolicyPropertyManager::uninitializeProperty ( QtProperty * property )

overrideprotectedvirtual

Reimplemented from QtAbstractPropertyManager.

◆ value()

QSizePolicy QtSizePolicyPropertyManager::value ( const QtProperty * property ) const

Returns the given property's value.

If the given property is not managed by this manager, this function returns the default size policy.

See also: setValue()

References d_ptr, and QtSizePolicyPropertyManagerPrivate::m_values.

◆ valueChanged

void QtSizePolicyPropertyManager::valueChanged	(	QtProperty *	property,
		const QSizePolicy &	value
	)

signal

This signal is emitted whenever a property created by this manager changes its value, passing a pointer to the property and the new value as parameters.
