程序的代码如下：

public void createPartControl(Composite parent) {
  parent.setLayout(new FillLayout(SWT.VERTICAL));
  final Composite top = new Composite(parent, SWT.EMBEDDED);
  //top.setLayout(new FillLayout());
  final Frame frame= SWT_AWT.new_Frame(top);//创建awt容器
  frame.setSize(parent.getSize().x,parent.getSize().y);
  
  
  try {
   SwingUtilities.invokeLater(new Runnable() {
    public void run() {
     Application.createInstance(frame);// 将当前容器传入，创建永中集成Office的实例     //at com.reader.editor.OfficeEditor$2.run(OfficeEditor.java:113)   就是指这一行

     Application.setTaskPanelVisible(GlobalConstants.CURRENT_PANE, false); //隐藏所有任务面板
     frame.add(Application.getInstance(), BorderLayout.CENTER);// 将当前返回得到的永中Office实例加入到当前容器中
     Application.refresh(); // 刷新视图
    }
   });  
  } catch (Exception e) {
      this.dispose();
   e.printStackTrace();
  }
  
}
