MyEclipsse 使用Jigloo插件开发SWT应用

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：

package main;

import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;
import org.eclipse.swt.graphics.Point;
import org.eclipse.swt.graphics.Rectangle;
import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.events.SelectionEvent;

public class NewComposite extends org.eclipse.swt.widgets.Composite {
	private Text text1;
	private Button OK;
	private Text text2;

	/**
	 * Auto-generated main method to display this
	 * org.eclipse.swt.widgets.Composite inside a new Shell.
	 */
	public static void main(String[] args) {
		showGUI();
	}

	/**
	 * Overriding checkSubclass allows this class to extend

	 */
	protected void checkSubclass() {
	}

	/**
	 * Auto-generated method to display this org.eclipse.swt.widgets.Composite
	 * inside a new Shell.
	 */
	public static void showGUI() {
		Display display = Display.getDefault();
		Shell shell = new Shell(display);
		NewComposite inst = new NewComposite(shell, SWT.NULL);
		Point size = inst.getSize();
		shell.setLayout(new FillLayout());
		shell.layout();
		if (size.x == 0 && size.y == 0) {
			inst.pack();
			shell.pack();
		} else {
			Rectangle shellBounds = shell.computeTrim(0, 0, size.x, size.y);
			shell.setSize(shellBounds.width, shellBounds.height);
		}
		shell.open();
		while (!shell.isDisposed()) {
			if (!display.readAndDispatch())
				display.sleep();
		}
	}

	public NewComposite(org.eclipse.swt.widgets.Composite parent, int style) {
		super(parent, style);
		initGUI();
	}

	private void initGUI() {
		try {
			this.setLayout(null);
			this.setSize(251, 151);
			{
				text1 = new Text(this, SWT.NONE);
				text1.setBounds(48, 18, 161, 30);
			}
			{
				text2 = new Text(this, SWT.NONE);
				text2.setBounds(48, 71, 161, 30);
			}
			{
				OK = new Button(this, SWT.PUSH | SWT.CENTER);
				OK.setText("OK");
				OK.setBounds(98, 113, 60, 30);
				OK.addSelectionListener(new SelectionAdapter() {
					public void widgetSelected(SelectionEvent evt) {
						System.out.println("OK.widgetSelected, event="+evt);
						//TODO add your code for OK.widgetSelected
						text2.setText(Converter.doConvert(text1.getText()));//此为需要手动添加的代码
					}
				});
			}
			this.layout();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

　　程序的运行结果如下图：
