Detailed Description

The QtRectFPropertyManager provides and manages QRectF properties.

A rectangle property has nested x, y, width and height 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.

A rectangle property also has a constraint rectangle which can be retrieved using the constraint() function, and set using the setConstraint() slot.

In addition, QtRectFPropertyManager provides the valueChanged() signal which is emitted whenever a property created by this manager changes, and the constraintChanged() signal which is emitted whenever such a property changes its constraint rectangle.

Constructor & Destructor Documentation

Creates a manager with the given parent.

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


Member Function Documentation

QRectF QtRectFPropertyManager::constraint ( const QtProperty property) const

Returns the given property's constraining rectangle. If returned value is null QRectF it means there is no constraint applied.

See also:
value(), setConstraint()
void QtRectFPropertyManager::constraintChanged ( QtProperty property,
const QRectF &  constraint 
) [signal]

This signal is emitted whenever property changes its constraint rectangle, passing a pointer to the property and the new constraint rectangle as parameters.

See also:
setConstraint()
int QtRectFPropertyManager::decimals ( const QtProperty property) const

Returns the given property's precision, in decimals.

See also:
setDecimals()
void QtRectFPropertyManager::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 QtRectFPropertyManager::initializeProperty ( QtProperty property) [protected, virtual]
void QtRectFPropertyManager::setConstraint ( QtProperty property,
const QRectF &  constraint 
) [slot]

Sets the given property's constraining rectangle to constraint.

When setting the constraint, the current value is adjusted if necessary (ensuring that the current rectangle value is inside the constraint). In order to reset the constraint pass a null QRectF value.

See also:
setValue(), constraint(), constraintChanged()
void QtRectFPropertyManager::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 QtRectFPropertyManager::setValue ( QtProperty property,
const QRectF &  value 
) [slot]

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

If the specified value is not inside the given property's constraining rectangle, the value is adjusted accordingly to fit within the constraint.

See also:
value(), setConstraint(), valueChanged()

Returns the manager that creates the nested x, y, width and height subproperties.

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

See also:
QtAbstractPropertyBrowser::setFactoryForManager()
void QtRectFPropertyManager::uninitializeProperty ( QtProperty property) [protected, virtual]

Reimplemented from QtAbstractPropertyManager.

QRectF QtRectFPropertyManager::value ( const QtProperty property) const

Returns the given property's value.

If the given property is not managed by this manager, this function returns an invalid rectangle.

See also:
setValue(), constraint()
void QtRectFPropertyManager::valueChanged ( QtProperty property,
const QRectF &  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()
QString QtRectFPropertyManager::valueText ( const QtProperty property) const [protected, virtual]

Reimplemented from QtAbstractPropertyManager.
