Constructor & Destructor Documentation

◆ QtMarginsPropertyManager()

QtMarginsPropertyManager ( QObject *  parent = nullptr)

Creates a manager with the given parent.

◆ ~QtMarginsPropertyManager()

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

Member Function Documentation

◆ constraint()

QMargins constraint ( const QtProperty property) const

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

See also
value(), setConstraint()

◆ constraintChanged

void constraintChanged ( QtProperty property,
const QMargins &  constraint 
)
signal

◆ initializeProperty()

void initializeProperty ( QtProperty property)
protectedvirtual

This function is called whenever a new valid property pointer has been created, passing the pointer as parameter.

The purpose is to let the manager know that the property has been created so that it can provide additional attributes for the new property, e.g. QtIntPropertyManager adds {QtIntPropertyManager::value()}{value}, {QtIntPropertyManager::minimum()}{minimum} and {QtIntPropertyManager::maximum()}{maximum} attributes. Since each manager subclass adds type specific attributes, this function is pure virtual and must be reimplemented when deriving from the QtAbstractPropertyManager class.

See also
addProperty(), createProperty()

Implements QtAbstractPropertyManager.

◆ setConstraint

void setConstraint ( QtProperty property,
const QMargins &  constraint 
)
slot

Sets the given property's constraining margins to constraint.

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

See also
setValue(), constraint(), constraintChanged()

◆ setValue

void setValue ( QtProperty property,
const QMargins &  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()

◆ subIntPropertyManager()

QtIntPropertyManager * subIntPropertyManager ( ) const

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()

◆ uninitializeProperty()

void uninitializeProperty ( QtProperty property)
protectedvirtual

This function is called just before the specified property is destroyed.

The purpose is to let the property manager know that the property is being destroyed so that it can remove the property's additional attributes.

See also
clear(), propertyDestroyed()

Reimplemented from QtAbstractPropertyManager.

◆ value()

QMargins 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()

◆ valueChanged

void valueChanged ( QtProperty property,
const QMargins &  val 
)
signal

◆ valueText()

QString valueText ( const QtProperty property) const
protectedvirtual

Returns a string representing the current state of the given property.

The default implementation of this function returns an empty string.

See also
QtProperty::valueText()

Reimplemented from QtAbstractPropertyManager.
