Detailed Description

The QtPointFPropertyManager provides and manages QPointF properties.

A point property has nested x and y 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 a QtDoublePropertyManager object. This manager can be retrieved using the subDoublePropertyManager() 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, QtPointFPropertyManager provides the valueChanged() signal which is emitted whenever a property created by this manager changes.

Member Function Documentation

◆ decimals()

int QtPointFPropertyManager::decimals ( const QtProperty * property ) const

Returns the given property's precision, in decimals.

See also: setDecimals()

References QtPointFPropertyManagerPrivate::Data::decimals, getData(), and QtAbstractPropertyManager::QtProperty.

Referenced by initializeProperty().

◆ decimalsChanged

void QtPointFPropertyManager::decimalsChanged	(	QtProperty *	property,
		int	prec )

signal

This signal is emitted whenever a property created by this manager changes its precision of value, passing a pointer to the property and the new prec value

See also: setDecimals()

References QtPointFPropertyManager(), and QtAbstractPropertyManager::QtProperty.

Referenced by setDecimals().

◆ initializeProperty()

void QtPointFPropertyManager::initializeProperty ( QtProperty * property )

overrideprotectedvirtual

Implementation of virtual method

Implements QtAbstractPropertyManager.

References QtProperty::addSubProperty(), decimals(), QtAbstractPropertyManager::QtProperty, and QtProperty::setPropertyName().

◆ setDecimals

void QtPointFPropertyManager::setDecimals	(	QtProperty *	property,
		int	prec )

slot

Sets the precision of the given property to prec.

The valid decimal range is 0-13. The default is 2.

See also: decimals()

References QtPointFPropertyManagerPrivate::Data::decimals, decimalsChanged(), and QtAbstractPropertyManager::QtProperty.

◆ setValue

void QtPointFPropertyManager::setValue	(	QtProperty *	property,
		const QPointF &	value )

slot

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

See also: value(), valueChanged()

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

◆ subDoublePropertyManager()

QtDoublePropertyManager * QtPointFPropertyManager::subDoublePropertyManager ( ) const

Returns the manager that creates the nested x and y subproperties.

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 QtPointFPropertyManager::uninitializeProperty ( QtProperty * property )

overrideprotectedvirtual

Implementation of virtual method

Reimplemented from QtAbstractPropertyManager.

References QtAbstractPropertyManager::QtProperty.

◆ value()

QPointF QtPointFPropertyManager::value ( const QtProperty * property ) const

Returns the given property's value.

If the given property is not managed by this manager, this function returns a point with coordinates (0, 0).

See also: setValue()

References getValue(), and QtAbstractPropertyManager::QtProperty.

◆ valueChanged

void QtPointFPropertyManager::valueChanged	(	QtProperty *	property,
		const QPointF &	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.
