init
public final void init(java.beans.PropertyDescriptor descriptor)
- Initializes this property editor with the enumerated items. Instances
can be shared but there are issues.
This method does a lot of jiggery pokery since enumerated
types are unlike any other homogenous types. Enumerated types may not
represent the same set of values.
One method would be to empty the list of values which would have the
side effect of firing notification events. Another method would be to
recreate the combobox.
