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.

See also QtAbstractPropertyManager, QtDoublePropertyManager, and QtPointPropertyManager.

Member Function Documentation

QtPointFPropertyManager::QtPointFPropertyManager ( QObject * parent = 0 )

Creates a manager with the given parent.

QtPointFPropertyManager::~QtPointFPropertyManager ()

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

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

Returns the given property's precision, in decimals.

See also setDecimals().

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().

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().

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() and valueChanged().

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().

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().

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.

See also setValue().
