Detailed Description

The QtSizeFPropertyManager provides and manages QSizeF properties.

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 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 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, QtSizeFPropertyManager 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.

Here is the caller graph for this function:

◆ decimalsChanged

void QtSizeFPropertyManager::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

Here is the caller graph for this function:

◆ initializeProperty()

void QtSizeFPropertyManager::initializeProperty ( QtProperty * property )

overrideprotectedvirtual

\reimp

Implements QtAbstractPropertyManager.

References QtAbstractPropertyManager::addProperty(), QtProperty::addSubProperty(), decimals(), QtSizeFPropertyManagerPrivate::m_doublePropertyManager, QtSizeFPropertyManagerPrivate::m_hToProperty, QtSizeFPropertyManagerPrivate::m_propertyToH, QtSizeFPropertyManagerPrivate::m_propertyToW, QtSizeFPropertyManagerPrivate::m_values, QtSizeFPropertyManagerPrivate::m_wToProperty, QtDoublePropertyManager::setDecimals(), QtDoublePropertyManager::setMinimum(), QtProperty::setPropertyName(), and QtDoublePropertyManager::setValue().

Here is the call graph for this function:

◆ maximum()

QSizeF QtSizeFPropertyManager::maximum ( const QtProperty * property ) const

Returns the given property's maximum size value.

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

References QtSizeFPropertyManagerPrivate::m_values.

◆ minimum()

QSizeF QtSizeFPropertyManager::minimum ( const QtProperty * property ) const

Returns the given property's minimum size value.

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

References QtSizeFPropertyManagerPrivate::m_values.

◆ rangeChanged

void QtSizeFPropertyManager::rangeChanged	(	QtProperty *	property,
		const QSizeF &	minimum,
		const QSizeF &	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()

Referenced by setMaximum(), setMinimum(), and setRange().

Here is the caller graph for this function:

◆ setDecimals

void QtSizeFPropertyManager::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()

References QtSizeFPropertyManagerPrivate::Data::decimals, decimalsChanged(), QtSizeFPropertyManagerPrivate::m_doublePropertyManager, QtSizeFPropertyManagerPrivate::m_propertyToH, QtSizeFPropertyManagerPrivate::m_propertyToW, QtSizeFPropertyManagerPrivate::m_values, and QtDoublePropertyManager::setDecimals().

Here is the call graph for this function:

◆ setMaximum

void QtSizeFPropertyManager::setMaximum	(	QtProperty *	property,
		const QSizeF &	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()

References QtSizeFPropertyManagerPrivate::Data::maximumValue(), QtAbstractPropertyManager::propertyChanged(), rangeChanged(), QtSizeFPropertyManagerPrivate::Data::setMaximumValue(), QtSizeFPropertyManagerPrivate::setRange(), and valueChanged().

Here is the call graph for this function:

◆ setMinimum

void QtSizeFPropertyManager::setMinimum	(	QtProperty *	property,
		const QSizeF &	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()

References QtSizeFPropertyManagerPrivate::Data::minimumValue(), QtAbstractPropertyManager::propertyChanged(), rangeChanged(), QtSizeFPropertyManagerPrivate::Data::setMinimumValue(), QtSizeFPropertyManagerPrivate::setRange(), and valueChanged().

Here is the call graph for this function:

◆ setRange

void QtSizeFPropertyManager::setRange	(	QtProperty *	property,
		const QSizeF &	minimum,
		const QSizeF &	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()

References QtAbstractPropertyManager::propertyChanged(), rangeChanged(), QtSizeFPropertyManagerPrivate::setRange(), and valueChanged().

Here is the call graph for this function:

◆ setValue

void QtSizeFPropertyManager::setValue	(	QtProperty *	property,
		const QSizeF &	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.

Here is the caller graph for this function:

◆ subDoublePropertyManager()

QtDoublePropertyManager * QtSizeFPropertyManager::subDoublePropertyManager ( ) 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.
