Detailed Description

The QtFlagPropertyManager provides and manages flag properties.

Each flag property has an associated list of flag names which can be retrieved using the flagNames() function, and set using the corresponding setFlagNames() function.

The flag manager provides properties with nested boolean subproperties representing each flag, i.e. a flag property's value is the binary combination of the subproperties' values. A property's value can be retrieved and set using the value() and setValue() slots respectively. The combination of flags is represented by single int value - that's why it's possible to store up to 32 independent flags in one flag property.

The subproperties are created by a QtBoolPropertyManager object. This manager can be retrieved using the subBoolPropertyManager() function. In order to provide editing widgets for the subproperties in a property browser widget, this manager must be associated with an editor factory.

In addition, QtFlagPropertyManager provides the valueChanged() signal which is emitted whenever a property created by this manager changes, and the flagNamesChanged() signal which is emitted whenever the list of flag names is altered.

Constructor & Destructor Documentation

◆ QtFlagPropertyManager()

QtFlagPropertyManager::QtFlagPropertyManager ( QObject * parent = nullptr )

Creates a manager with the given parent.

References QtAbstractPropertyManager::propertyDestroyed(), QtAbstractPropertyManager::QtAbstractPropertyManager(), QtAbstractPropertyManager::QtProperty, and valueChanged().

Referenced by flagNamesChanged().

◆ ~QtFlagPropertyManager()

QtFlagPropertyManager::~QtFlagPropertyManager ( )

override

Destroys this manager, and all the properties it has created.

Member Function Documentation

◆ flagNames()

QStringList QtFlagPropertyManager::flagNames ( const QtProperty * property ) const

Returns the given property's list of flag names.

See also: value(), setFlagNames()

References QtFlagPropertyManagerPrivate::Data::flagNames, getData(), and QtAbstractPropertyManager::QtProperty.

Referenced by setFlagNames().

◆ flagNamesChanged

void QtFlagPropertyManager::flagNamesChanged	(	QtProperty *	property,
		const QStringList &	names )

signal

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

See also: setFlagNames()

References QtFlagPropertyManager(), and QtAbstractPropertyManager::QtProperty.

Referenced by setFlagNames().

◆ initializeProperty()

void QtFlagPropertyManager::initializeProperty ( QtProperty * property )

overrideprotectedvirtual

Implementation of virtual method

Implements QtAbstractPropertyManager.

References QtAbstractPropertyManager::QtProperty.

◆ setFlagNames

void QtFlagPropertyManager::setFlagNames	(	QtProperty *	property,
		const QStringList &	flagNames )

slot

Sets the given property's list of flag names to flagNames. The property's current value is reset to 0 indicating the first item of the list.

See also: flagNames(), flagNamesChanged()

References flagNames(), QtFlagPropertyManagerPrivate::Data::flagNames, flagNamesChanged(), QtAbstractPropertyManager::propertyChanged(), QtAbstractPropertyManager::QtProperty, QtFlagPropertyManagerPrivate::Data::val, and valueChanged().

◆ setValue

void QtFlagPropertyManager::setValue	(	QtProperty *	property,
		int	value )

slot

Sets the value of the given property to value. Nested properties are updated automatically.

The specified value must be less than the binary combination of the property's flagNames() list size (i.e. less than 2^n, where n is the size of the list) and larger than (or equal to) 0.

See also: value(), valueChanged()

References QtFlagPropertyManagerPrivate::Data::flagNames, QtAbstractPropertyManager::propertyChanged(), QtAbstractPropertyManager::QtProperty, QtFlagPropertyManagerPrivate::Data::val, and valueChanged().

◆ subBoolPropertyManager()

QtBoolPropertyManager * QtFlagPropertyManager::subBoolPropertyManager ( ) const

Returns the manager that produces the nested boolean subproperties representing each flag.

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

See also: QtAbstractPropertyBrowser::setFactoryForManager()

◆ uninitializeProperty()

void QtFlagPropertyManager::uninitializeProperty ( QtProperty * property )

overrideprotectedvirtual

Implementation of virtual method

Reimplemented from QtAbstractPropertyManager.

References QtAbstractPropertyManager::QtProperty.

◆ value()

int QtFlagPropertyManager::value ( const QtProperty * property ) const

Returns the given property's value.

If the given property is not managed by this manager, this function returns 0.

See also: flagNames(), setValue()

References getValue(), and QtAbstractPropertyManager::QtProperty.

◆ valueChanged

void QtFlagPropertyManager::valueChanged	(	QtProperty *	property,
		int	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.
