Java可视化开发-WindowBuilder

一.WindowBuilder介绍

WindowBuilder 由 SWT Designer 和 Swing Designer 组成，可以非常轻松地创建 Java GUI 应用程序，而无需花费大量时间编写代码。使用所见即所得的可视化设计器和布局工具，为复杂的窗口创建简单的表单；将为您生成 Java 代码。使用拖放轻松添加控件、向控件添加事件处理程序、使用属性编辑器更改控件的各种属性、国际化您的应用程序等等。

WindowBuilder 构建为 Eclipse 和各种基于 Eclipse 的 IDE（RAD、RSA、MyEclipse、JBuilder 等）的插件。该插件构建了一个抽象语法树 (AST) 来导航源代码，并使用 GEF 来显示和管理可视化呈现。

生成的代码不需要任何额外的自定义库来编译和运行：所有生成的代码都可以在没有安装 WindowBuilder Pro 的情况下使用。WindowBuilder Pro 几乎可以读写任何格式，并且可以对大多数手写的 Java GUI 代码进行逆向工程。它还支持自由格式的代码编辑（在任何地方进行更改……不仅仅是在特殊区域）和大多数用户重构（您可以毫无问题地移动、重命名和细分方法）。

二.下载安装

因为WindowBuilder是基于Eclipse的,所有要先安装Eclipse.

如果没有,可以从Eclipse Downloads | The Eclipse Foundation下载 Eclipse.

打开eclipse,如图所示,搜索WindowBuilder并安装

 

同意安装协议,然后傻瓜式安装完毕 

 三.实战

1.新建一个JavaJUI项目

2.设计窗体

3.成品下载

filetools.jar

4.窗体代码展示
