分享下怎么把swt嵌入到swing中，另外再问点问题

Question

先上代码import java.awt.BorderLayout;
import java.awt.Canvas;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;import javax.swing.ImageIcon;
import javax.swing.JButton;

import org.eclipse.swt.browser.ProgressListener;
import org.eclipse.swt.browser.WindowEvent;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;public class Window extends JFrame {
private static final long serialVersionUID = 1L;
private JPanel panel;
private JButton b1 = new JButton("GO"),
b2 = new JButton("Add Data");
private JTextField textField = new JTextField(50);
static String path = "http://www.baidu.com";
static final Display display = Display.getDefault();
static Canvas canvas = null;
static Shell shell;
static Browser browser = null;

public Window() {
System.setProperty("sun.awt.xembedserver", "true");
canvas = new Canvas() {
private static final long serialVersionUID = 1L;
@Override
public void addNotify() {
super.addNotify();
final Canvas canvas_ = this;
display.asyncExec(new Runnable() {
public void run() {
shell = SWT_AWT.new_Shell(display, canvas);
shell.setText("Slashdot");
shell.setLayout(new FillLayout());
browser = new Browser(shell, SWT.NONE);
browser.addProgressListener(new ProgressListener() {
public void changed(ProgressEvent event) {
} public void completed(ProgressEvent event) {
/*String script = "var a = new Array();" +
"a = document.getElementsByTagName(\"a\");" +
"for(i = 0; i < a.length; i++) {" +
"a[i].target = '_self';" +
"}";
browser.execute(script);*/
System.out.println("网页加载完成！");
}
});
browser.addOpenWindowListener(new OpenWindowListener() {
@Override
public void open(WindowEvent event) {
final Browser browser2 = new Browser(shell, SWT.NONE);
event.browser = browser2;
event.display.asyncExec(new Runnable() {
@Override
public void run() {
browser.setUrl(browser2.getUrl());
}
});
}

});
browser.setUrl(path);
browser.setVisible(true);
shell.setSize(canvas_.getWidth(), canvas_.getHeight());
shell.open();
while(!shell.isDisposed()){
if(!display.readAndDispatch()){
display.sleep();
}
}
}
});
}
};
panel = new JPanel();
panel.setLayout(new FlowLayout());
panel.add(textField);
b1.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
path = textField.getText();
display.asyncExec(new Runnable() {
public void run() {
browser.setUrl(path);
}
});
}

});
panel.add(b1);
add(BorderLayout.NORTH, panel);
add(BorderLayout.CENTER, canvas);
setSize(800, 600);
ImageIcon ii = new ImageIcon(this.getClass().getResource("image/debug_wiz.png")); 
setIconImage(ii.getImage());
setTitle("swt嵌入swing");
setBounds(200, 200, 800, 600);
setVisible(true);
}

static Window window;

public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
window = new Window();
}
});
while(true){
if(!display.readAndDispatch()){
display.sleep();
}
}
}
}
问题就是，我这么做在关闭窗口的时候，窗口虽然关闭了，但是这个类还在运行，具体可以运行下试试。我要怎么做才能正确的关闭呢。

Answer 1

你在Window()构造方法的最后添加一行
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
试试行不行

附带给刚学习SWT的同学说下，这个程序要跑的话需要swt-awt-win32.dll，将这个文件放到classpath当中，否则会报错import java.awt.BorderLayout;

Answer 3

我也再提醒下大家，这个程序要跑的话除了要有swt-awt-win32.dll还要在Window这个目录下有一个image目录里面有一张图片叫debug_wiz.png当然你可以改一下下面两句。去掉也行。 ImageIcon ii = new ImageIcon(this.getClass().getResource("image/debug_wiz.png")); 
 setIconImage(ii.getImage());
