An event object describing a change to a named property.
This concrete class was designed to be instantiated, but may also be subclassed if required.
The JFace frameworks contain classes that report property change events for internal state changes that may be of interest to external parties. A special listener interface (IPropertyChangeListener
) is defined for this purpose, and a typical class allow listeners to be registered via an addPropertyChangeListener
method.

berry::PropertyChangeEvent::PropertyChangeEvent | ( | Object::Pointer | source, |
const QString & | property, | ||
Object::Pointer | oldValue, | ||
Object::Pointer | newValue | ||
) |
Creates a new property change event.
source | the object whose property has changed |
property | the property that has changed (must not be null ) |
oldValue | the old value of the property, or null if none |
newValue | the new value of the property, or null if none |
berry::PropertyChangeEvent::berryObjectMacro | ( | PropertyChangeEvent | ) |
Object::Pointer berry::PropertyChangeEvent::GetNewValue | ( | ) |
Returns the new value of the property.
null
if not known or not relevant (for instance if the property was removed). Object::Pointer berry::PropertyChangeEvent::GetOldValue | ( | ) |
Returns the old value of the property.
null
if not known or not relevant (for instance if the property was just added and there was no old value). QString berry::PropertyChangeEvent::GetProperty | ( | ) |
Returns the name of the property that changed.
Warning: there is no guarantee that the property name returned is a constant string. Callers must compare property names using equals, not ==.
Object::Pointer berry::PropertyChangeEvent::GetSource | ( | ) |
Returns the object whose property has changed
