Member Function Documentation

initializeProperty()

void VariantManager::initializeProperty ( QtProperty *  property )

protectedvirtual

This function is called whenever a new valid property pointer has been created, passing the pointer as parameter.

The purpose is to let the manager know that the property has been created so that it can provide additional attributes for the new property, e.g. QtIntPropertyManager adds {QtIntPropertyManager::value()}{value}, {QtIntPropertyManager::minimum()}{minimum} and {QtIntPropertyManager::maximum()}{maximum} attributes. Since each manager subclass adds type specific attributes, this function is pure virtual and must be reimplemented when deriving from the QtAbstractPropertyManager class.

addProperty(), createProperty()

Implements QtAbstractPropertyManager.

isPropertyTypeSupported()

bool VariantManager::isPropertyTypeSupported ( int  propertyType ) const

virtual

Returns true if the given propertyType is supported by this variant manager; otherwise false.

propertyType()

Reimplemented from QtVariantPropertyManager.

References QtVariantPropertyManager::isPropertyTypeSupported().

setValue

slotValueChanged

void VariantManager::slotValueChanged ( QtProperty *  property, const QVariant &  value  )

Referenced by VariantManager().

uninitializeProperty()

void VariantManager::uninitializeProperty ( QtProperty *  property )

protectedvirtual

This function is called just before the specified property is destroyed.

The purpose is to let the property manager know that the property is being destroyed so that it can remove the property's additional attributes.

See also

clear(), propertyDestroyed()

Reimplemented from QtAbstractPropertyManager.

References propertyToData, QtVariantPropertyManager::uninitializeProperty(), VariantManager::Data::x, xToProperty, VariantManager::Data::y, and yToProperty.

value()

QVariant VariantManager::value ( const QtProperty *  property ) const

virtual

Returns the given property's value.

If the given property is not managed by this manager, this function returns an invalid variant.

See also

setValue()

Reimplemented from QtVariantPropertyManager.

References propertyToData, and QtVariantPropertyManager::value().

Referenced by slotValueChanged().

valueText()

QString VariantManager::valueText ( const QtProperty *  property ) const

virtual

Returns a string representing the current state of the given property.

The default implementation of this function returns an empty string.

See also

QtProperty::valueText()

Reimplemented from QtAbstractPropertyManager.

References propertyToData, and QtVariantPropertyManager::valueText().

valueType()

int VariantManager::valueType ( int  propertyType ) const

virtual

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Returns the value type associated with the given propertyType.

Reimplemented from QtVariantPropertyManager.

References QtVariantPropertyManager::valueType().
