Detailed Description

A font property has nested family, pointSize, bold, italic, underline, strikeOut and kerning 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 QtIntPropertyManager, QtEnumPropertyManager and QtBoolPropertyManager objects. These managers can be retrieved using the corresponding subIntPropertyManager(), subEnumPropertyManager() and subBoolPropertyManager() functions. In order to provide editing widgets for the subproperties in a property browser widget, these managers must be associated with editor factories.

In addition, QtFontPropertyManager provides the valueChanged() signal which is emitted whenever a property created by this manager changes.

Constructor & Destructor Documentation

QtFontPropertyManager()

QtFontPropertyManager

(

QObject *

parent = nullptr

)

Creates a manager with the given parent.

~QtFontPropertyManager()

~QtFontPropertyManager

(

)

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.

setValue

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

slot

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

See also

value(), valueChanged()

subBoolPropertyManager()

QtBoolPropertyManager * subBoolPropertyManager

(

)

const

Returns the manager that creates the bold, italic, underline, strikeOut and kerning subproperties.

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

See also

QtAbstractPropertyBrowser::setFactoryForManager()

subEnumPropertyManager()

QtEnumPropertyManager * subEnumPropertyManager

(

)

const

Returns the manager that create the family subproperty.

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

See also

QtAbstractPropertyBrowser::setFactoryForManager()

subIntPropertyManager()

QtIntPropertyManager * subIntPropertyManager

(

)

const

Returns the manager that creates the pointSize subproperty.

In order to provide editing widgets for the pointSize property 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()

QFont value

(

const QtProperty *

property

)

const

Returns the given property's value.

If the given property is not managed by this manager, this function returns a font object that uses the application's default font.

See also

setValue()

valueChanged

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

valueIcon()

QIcon valueIcon ( const QtProperty *  property ) const

protectedvirtual

Returns an icon representing the current state of the given property.

The default implementation of this function returns an invalid icon.

See also

QtProperty::valueIcon()

Reimplemented from QtAbstractPropertyManager.

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.

QtProperty::valueText()

Reimplemented from QtAbstractPropertyManager.
