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::~QtVariantProperty ( )

override

Destroys this property.

See also: QtProperty::~QtProperty()

◆ QtVariantProperty()

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

◆ attributeValue()

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

Returns this property's value for the specified attribute.

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

See also: setAttribute()

References QtVariantPropertyManager::attributeValue(), and QtVariantPropertyPrivate::manager.

Here is the call graph for this function:

◆ propertyType()

int QtVariantProperty::propertyType ( ) const

Returns this property's type.

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

See also: valueType()

References QtVariantPropertyPrivate::manager, and QtVariantPropertyManager::propertyType().

Here is the call graph for this function:

◆ setAttribute() [1/2]

void QtVariantProperty::setAttribute	(	const QString &	attribute,
		const QMap< int, QIcon > &	value
	)

virtual

Added in CamiTK. In order to manage setting the icons list, the QtEnumPropertyManager needs a QMap<int,QIcon> But QMap<int,QIcon> cannot be transformed to QVariant, therefore this method had to be added.

References QtVariantPropertyPrivate::manager, QtVariantPropertyManager::setAttribute(), and value().

Here is the call graph for this function:

◆ setAttribute() [2/2]

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

Sets the attribute of property to value.

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

See also: attributeValue()

References QtVariantPropertyPrivate::manager, QtVariantPropertyManager::setAttribute(), and value().

Referenced by ObjectControllerPrivate::addClassProperties(), camitk::ObjectControllerPrivate::addDynamicProperties(), camitk::ObjectControllerPrivate::buildQtVariantProperty(), and main().

Here is the call graph for this function:

Here is the caller graph for this function:

◆ setValue()

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.
