Detailed Description

The QtVariantProperty class is a convenience class handling QVariant based properties.

QtVariantProperty provides additional API: A property's type, value type, attribute values and current value can easily be retrieved using the propertyType(), valueType(), attributeValue() and value() functions respectively. In addition, the attribute values and the current value can be set using the corresponding setValue() and setAttribute() functions.

For example, instead of writing:

QtVariantPropertyManager *variantPropertyManager;
QtProperty *property;
variantPropertyManager->setValue(property, 10);

you can write:

QtVariantPropertyManager *variantPropertyManager;
QtVariantProperty *property;
property->setValue(10);

QtVariantProperty instances can only be created by the QtVariantPropertyManager class.

Constructor & Destructor Documentation

QtVariantProperty::~QtVariantProperty ( )

Destroys this property.

See also
QtProperty::~QtProperty()
QtVariantProperty::QtVariantProperty ( QtVariantPropertyManager *  manager)
protected

Creates a variant property using the given manager.

Do not use this constructor to create variant property instances; use the QtVariantPropertyManager::addProperty() function instead. This constructor is used internally by the QtVariantPropertyManager::createProperty() function.

Member Function Documentation

QVariant QtVariantProperty::attributeValue ( const QString &  attribute) const

Returns this property's value for the specified attribute.

QtVariantPropertyManager provides a couple of related functions: {QtVariantPropertyManager::attributes()}{attributes()} and {QtVariantPropertyManager::attributeType()}{attributeType()}.

See also
setAttribute()
int QtVariantProperty::propertyType ( ) const

Returns this property's type.

QtVariantPropertyManager provides several related functions: {QtVariantPropertyManager::enumTypeId()}{enumTypeId()}, {QtVariantPropertyManager::flagTypeId()}{flagTypeId()} and {QtVariantPropertyManager::groupTypeId()}{groupTypeId()}.

See also
valueType()
void QtVariantProperty::setAttribute ( const QString &  attribute,
const QVariant &  value 
)

Sets the attribute of property to value.

QtVariantPropertyManager provides the related {QtVariantPropertyManager::setAttribute()}{setAttribute()} function.

See also
attributeValue()
void QtVariantProperty::setValue ( const QVariant &  value)

Sets the value of this property to value.

The specified value must be of the type returned by valueType(), or of a type that can be converted to valueType() using the QVariant::canConvert() function; otherwise this function does nothing.

See also
value()
QVariant QtVariantProperty::value ( ) const

Returns the property's current value.

See also
valueType(), setValue()
int QtVariantProperty::valueType ( ) const

Returns the type of this property's value.
