Answer 2

你用JBuilder做的吧！呵呵
this(new Frame(), "Dialog1", true);上面这句才是我要的啊！不过，我怎么理解，为什么 new Frame() 一下，dialog 就显示在原来的Frame上面？？？？这个 dialog 不是应该在在刚刚 建立的 new Frame() 上面的吗？

Answer 3

哦，我知道为什么了啊！主要是模态的关系但是，dialog 用模态，还达不到我要做的东西的要求啊！

Answer 4

我这个主要是用在JInternalFrame里的JTable里，我想要做的是，当鼠标双击，JTable的某行，系统就会跟该行相关的信息对话框dialog如果，用以上方法“this(new Frame(), "Dialog1", true);”那么我的双击事件就变成了单击事件了啊我把我的代码粘出来，希望高手再来！！！！！！//这是我做双击事件专门写了的一个内类
class doubleClick extends MouseAdapter{

private boolean click=false;
     private  long firstClick=0;
   private long secondClick=0;
   private int rowI=-1;
    private JInternalFrame inframe;
    
    public doubleClick(JInternalFrame inframe){
     this.inframe=inframe;
    }
    
public void mouseClicked(MouseEvent e){
if(click==false){
firstClick=new Date().getTime();
               click=true;
            }else if(click==true){
         secondClick=new Date().getTime();
         click=false;
            }
            if (Math.abs((secondClick-firstClick)) < 300 && (secondClick-firstClick) > 30){ 
               exe(e);
            }
        }
        public void mousePressed(MouseEvent e) { 
if(click==false){
               firstClick=new Date().getTime();
               click=true;
            }else if(click==true){
               secondClick=new Date().getTime();
               click=false;
            }
            if (Math.abs((secondClick-firstClick)) < 300 && (secondClick-firstClick) > 30){ 
               exe(e);
            }
        }

private void exe(MouseEvent e){
rowI  = table.rowAtPoint(e.getPoint());// 得到table的行号
if (rowI > -1){
String id=table.getValueAt(rowI, 0).toString();
dialog(id);
}
}

private void dialog(String id){//这个就是我要显示相关信息的dialog
                  //本来在这个函数里，没有下面的3句号，双击事件是可以的，
                  //但是有了这三句话，双击就变单击了，
JDialog dialog=new JDialog(new Frame(),"hello",true);
dialog.setSize(400,300);
dialog.setVisible(true);
System.out.println(id);
}
}
