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.
QtFontPropertyManager | ( | QObject * | parent = nullptr | ) |
Creates a manager with the given parent.
Destroys this manager, and all the properties it has created.
|
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.
Implements QtAbstractPropertyManager.
|
slot |
Sets the value of the given property to value. Nested properties are updated automatically.
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.
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.
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.
|
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.
Reimplemented from QtAbstractPropertyManager.
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.
|
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.
|
protectedvirtual |
Returns an icon representing the current state of the given property.
The default implementation of this function returns an invalid icon.
Reimplemented from QtAbstractPropertyManager.
|
protectedvirtual |
Returns a string representing the current state of the given property.
The default implementation of this function returns an empty string.
Reimplemented from QtAbstractPropertyManager.
