Detailed Description

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.

PropertyChangeEvent

)

GetNewValue()

Object::Pointer berry::PropertyChangeEvent::GetNewValue

(

)

Returns the new value of the property.

Returns

the new value, or null if not known or not relevant (for instance if the property was removed).

GetOldValue()

Object::Pointer berry::PropertyChangeEvent::GetOldValue

(

)

Returns the old value of the property.

Returns

the old value, or null if not known or not relevant (for instance if the property was just added and there was no old value).

GetProperty()

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 ==.

Returns

the name of the property that changed

GetSource()

Object::Pointer berry::PropertyChangeEvent::GetSource

(

)

Returns the object whose property has changed

Returns

the object whose property has changed
