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

◆ QtRectFPropertyManager()

QtRectFPropertyManager::QtRectFPropertyManager ( QObject *  parent = nullptr)

Creates a manager with the given parent.

References QtRectFPropertyManagerPrivate::m_doublePropertyManager, QtAbstractPropertyManager::propertyDestroyed(), and valueChanged().

◆ ~QtRectFPropertyManager()

QtRectFPropertyManager::~QtRectFPropertyManager ( )
override

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

Member Function Documentation

◆ constraint()

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()

References QtRectFPropertyManagerPrivate::Data::constraint, and QtRectFPropertyManagerPrivate::m_values.

Referenced by setConstraint().

+ Here is the caller graph for this function:

◆ constraintChanged

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.

setConstraint()

+ Here is the caller graph for this function:

◆ decimals()

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

Returns the given property's precision, in decimals.

+ Here is the caller graph for this function:

◆ decimalsChanged

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

◆ initializeProperty()

void QtRectFPropertyManager::initializeProperty ( QtProperty *  property)
overrideprotectedvirtual

\reimp

Implements QtAbstractPropertyManager.

+ Here is the call graph for this function:

◆ setConstraint

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.

+ Here is the call graph for this function:

◆ setDecimals

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.

+ Here is the call graph for this function:

◆ setValue

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.

QtDoublePropertyManager * QtRectFPropertyManager::subDoublePropertyManager ( ) const

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