Method Detail

setValue

public final void setValue(java.lang.Object value)

Specified by:

setValue in interface java.beans.PropertyEditor

getJavaInitializationString

public final java.lang.String getJavaInitializationString()

Specified by:

getJavaInitializationString in interface java.beans.PropertyEditor

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.

Overrides:

init in class EditorSupport

actionPerformed

public final void actionPerformed(java.awt.event.ActionEvent evt)

Event is set when a combo selection changes.
