クラス SwingWorker

java.lang.Object

pexa.client.std.view.swing.SwingWorker

public abstract class SwingWorker
extends java.lang.Object

Swingを使用したアプリケーション内で、バックグランドで処理を実行するための ワーカークラスを作成するための抽象実装クラスです。

このクラスは、JDK6においては標準で取り込まれる予定なので、その後はこの クラスはJDK標準クラスをExtendsしたアダプタクラスに変更される予定です。

This is the 3rd version of SwingWorker (also known as SwingWorker 3), an abstract class that you subclass to perform GUI-related work in a dedicated thread. For instructions on using this class, see: http://java.sun.com/docs/books/tutorial/uiswing/misc/threads.html Note that the API changed slightly in the 3rd version: You must now invoke start() on the SwingWorker after creating it.

start

public void start()
