Detailed Description

A size property has nested 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 QtIntPropertyManager object. This manager can be retrieved using the subIntPropertyManager() 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 size property also has a range of valid values defined by a minimum size and a maximum size. These sizes can be retrieved using the minimum() and the maximum() functions, and set using the setMinimum() and setMaximum() slots. Alternatively, the range can be defined in one go using the setRange() slot.

In addition, QtSizePropertyManager provides the valueChanged() signal which is emitted whenever a property created by this manager changes, and the rangeChanged() signal which is emitted whenever such a property changes its range of valid sizes.

Constructor & Destructor Documentation

◆ QtSizePropertyManager()

QtSizePropertyManager ( QObject * parent = nullptr )

Creates a manager with the given parent.

◆ ~QtSizePropertyManager()

~QtSizePropertyManager ( )

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

Member Function Documentation

◆ 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.

◆ maximum()

QSize maximum ( const QtProperty * property ) const

Returns the given property's maximum size value.

See also: setMaximum(), minimum(), setRange()

◆ minimum()

QSize minimum ( const QtProperty * property ) const

Returns the given property's minimum size value.

See also: setMinimum(), maximum(), setRange()

◆ rangeChanged

void rangeChanged	(	QtProperty *	property,
		const QSize &	minimum,
		const QSize &	maximum
	)

signal

This signal is emitted whenever a property created by this manager changes its range of valid sizes, passing a pointer to the property and the new minimum and maximum sizes.

See also: setRange()

◆ setMaximum

void setMaximum	(	QtProperty *	property,
		const QSize &	maxVal
	)

slot

Sets the maximum size value for the given property to maxVal.

When setting the maximum size value, the minimum and current values are adjusted if necessary (ensuring that the size range remains valid and that the current value is within the range).

See also: maximum(), setRange(), rangeChanged()

◆ setMinimum

void setMinimum	(	QtProperty *	property,
		const QSize &	minVal
	)

slot

Sets the minimum size value for the given property to minVal.

When setting the minimum size value, the maximum and current values are adjusted if necessary (ensuring that the size range remains valid and that the current value is within the range).

See also: minimum(), setRange(), rangeChanged()

◆ setRange

void setRange	(	QtProperty *	property,
		const QSize &	minimum,
		const QSize &	maximum
	)

slot

Sets the range of valid values.

This is a convenience function defining the range of valid values in one go; setting the minimum and maximum values for the given property with a single function call.

When setting a new range, the current value is adjusted if necessary (ensuring that the value remains within the range).

See also: setMinimum(), setMaximum(), rangeChanged()

◆ setValue

void setValue	(	QtProperty *	property,
		const QSize &	value
	)

slot

Sets the value of the given property to value.

If the specified value is not valid according to the given property's size range, the value is adjusted to the nearest valid value within the size range.

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

◆ subIntPropertyManager()

QtIntPropertyManager * subIntPropertyManager ( ) const

Returns the manager that creates the nested width and height subproperties.

In order to provide editing widgets for the width and height properties 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()

QSize 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 size

See also: setValue()

◆ valueChanged

void valueChanged	(	QtProperty *	property,
		const QSize &	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()

◆ 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.
