A point property has nested x and y 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.
In addition, QtPointFPropertyManager provides the valueChanged() signal which is emitted whenever a property created by this manager changes.
QtPointFPropertyManager | ( | QObject * | parent = nullptr | ) |
Creates a manager with the given parent.
Destroys this manager, and all the properties it has created.
int decimals | ( | const QtProperty * | property | ) | const |
Returns the given property's precision, in decimals.
|
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
|
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 precision of the given property to prec.
The valid decimal range is 0-13. The default is 2.
|
slot |
Sets the value of the given property to value. Nested properties are updated automatically.
QtDoublePropertyManager * subDoublePropertyManager | ( | ) | const |
Returns the manager that creates the nested x and y subproperties.
In order to provide editing widgets for the subproperties 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.
QPointF 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 point with coordinates (0, 0).
|
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 a string representing the current state of the given property.
The default implementation of this function returns an empty string.
Reimplemented from QtAbstractPropertyManager.
