java swing 内置浏览器打开网页显示flash图表-swt Browser应用

今天在网上找了好久如何用在java swing打开网页，从而实现显示网页图表的效果，功夫不负有心人，终于搞定了，下面把所用的类和swt.jar整理了一下，方便有需要的朋友使用。

用到的swt.jar下载

调用网页的Browser要结合现有的java控件使用，一下是结合panel定义的类(SWTPane.java)：

 

 /*

  * and open the template in the editor. 

  */  

 package desktopapplicationmenu.comm;  

   

 import java.awt.BorderLayout;  

 import java.awt.Canvas;  

 import java.awt.Panel;  

 import org.eclipse.swt.SWT;  

 import org.eclipse.swt.awt.SWT_AWT;  

 import org.eclipse.swt.browser.Browser;  

 import org.eclipse.swt.layout.FillLayout;  

   

 import org.eclipse.swt.widgets.Display;  

 import org.eclipse.swt.widgets.Shell;  

   

 /**

  */  

 public class SWTPane extends Panel {  

   

     DisplayThread displayThread;  

     private Canvas canvas;  

   

     public SWTPane() {  

         displayThread = new DisplayThread();  

         displayThread.start();  

         canvas = new Canvas();  

         setLayout(new BorderLayout());  

         add(canvas, BorderLayout.CENTER);  

     }  

  public static void main(String args[]) throws Exception {  

   

      java.awt.EventQueue.invokeLater(new Runnable() {  

   

             public void run() {  

                 new SWTPane().setVisible(true);  

             }  

         });  

        

  }  

     public void addNotify() {  

         super.addNotify();  

         Display dis = displayThread.getDisplay();  

         dis.syncExec(new Runnable() {  

   

             public void run() {  

                 Shell shell = SWT_AWT.new_Shell(displayThread.getDisplay(), canvas);  

                 shell.setLayout(new FillLayout());  

                 final Browser browser = new Browser(shell, SWT.NONE);  

                 browser.setLayoutData(BorderLayout.CENTER);  

                 browser.setUrl("http://www.my400800.cn");  

             }  

         });  

     }  

 }  

 

里面为了防止在打开网页的时候出现错误，封装了一下Thread类，定义如下(DisplayThread.java)：

 

/*

 * To change this template, choose Tools | Templates

 * and open the template in the editor.

 */

package desktopapplicationmenu.comm;



import org.eclipse.swt.widgets.Display;



/**

 *

 * @author liul

 */

public class DisplayThread extends Thread {



    private Display display;

    Object sem = new Object();



    public void run() {

        synchronized (sem) {

            display = Display.getDefault();

            sem.notifyAll();

        }

        swtEventLoop();

    }



    private void swtEventLoop() {

        while (true) {

            if (!display.readAndDispatch()) {

                display.sleep();

            }

        }

    }



    public Display getDisplay() {

        try {

            synchronized (sem) {

                while (display == null) {

                    sem.wait();

                }

                return display;

            }

        } catch (Exception e) {

            return null;

        }

    }

}

调用方法

        SWTPane jbtn_Sel = new SWTPane();
        jPanel1.add(jbtn_Sel);
        jbtn_Sel.setBounds(1, 1, 600, 600);
