# 一、序言 #

之前花了很多时间，找了很多方法，都没有把Swing插件给安装好，甚至几乎下载了NetBeans来进行尝试安装，利用其来进行Swing的练习。

经过一番努力，终于成功安装好了Swing插件，现在来分享一下我的安装经历。

# 二、安装Swing插件 #

## 1.在help中找到Eclipse marketplace ##

## 2.搜索Windowbuilder ##

## 3.直接安装即可 ##

没错，就是这么简单，之前说需要找到对应的版本，官方文档上的说明也只有4.2版本之前的说明（可能没有更新，也可能新的这个插件很强，都兼容了）  
我的Eclipse版本是4.16  
最后，我尝试安装了一下。嗯，完全可以使用！

# 三、简单演示 #

## 1.检测有无安装成功 ##

当你的建新窗口中，可以建新如下的文件的时候，就证明你安装成功了，可以使用Swing插件。

这样进行图形界面设计的时候，直接进行控件拖动就好了。

下面，以JFrame文件，OptionPaneTest进行测试。

## 2.对话框测试 ##

### 代码如下 ###

双击按钮控件编写按钮的代码，其余部分自动生成。

## 3.显示一个错误的信息框 ##
