安装Jigloo插件的步骤在此省略。
首先建一个Java项目，命名为Converter。其效果是制作出一个图形界面，向其输入一段文字，可以将此段文字倒序显示出来。
建立一个java文件，代码如下：
package main; public class Converter { public static String doConvert(String input) { String output = ""; char[] input0 = input.toCharArray(); for (int i = input0.length - 1; i >= 0; i--) { output += input0[i]; } return output; } }
然后在创建一个SWT Composite。它的本质为java文件，不过可以使用Form Editor将其转化为图形化开发界面。
使用图形开发界面，设计出下图画布布局：
使用最终代码如下：
