Constructor Detail

IndexChangeEvent

@Deprecated
public IndexChangeEvent(Object source,
                                   int type)

Deprecated. Please use IndexChangeEvent(Object, int, int) instead.

Parameters:

source - the table model which fired this event in the very beginning

type - the event type

IndexChangeEvent

public IndexChangeEvent(Object source,
                        int type,
                        int eventSerialNumber)

Constructor of this class.

You should always use this constructor to construct a new event.

To improve the performance, you need try your best to make the event serial number unique and paired for INDEX_CHANGING_EVENT and INDEX_CHANGED_EVENT. You could assign it to any positive number. Or you can try random() like the following code example.

 int number = ((Double) (Math.random() * 10000)).intValue();
 IndexChangeEvent e = new IndexChangeEvent(this, INDEX_CHANGING_EVENT, number);
 fireThisEvent(e);
 ....
 IndexChangeEvent e = new IndexChangeEvent(this, INDEX_CHANGED_EVENT, number);
 fireThisEvent(e);
 

Parameters:

source - the table model which fired this event in the very beginning

type - the event type

eventSerialNumber - the event serial number

public IndexChangeEvent(Object source,
                        int type,

                        boolean forceProcess,
