解决方案 »

  1.   

    Frame frm=new Frame();
    frm.show()
    你试试吧,都忘了
      

  2.   

    给按钮加事件。
    用netbeans做swing比较方便,可以搜一下怎么在netbean里拖拉组件做swing
    下面2个类是个例子。Good luck~import javax.swing.JFrame;/*

  3.   

    1.定义一个窗口类:
    class MyFrame extends Frame{
     public MyFrame(){
     } //定义构造函数
    }
    2.定义监听事件:
    public class buttonListener implements ActionListener{
     public void actionPerformed(ActionEvent e){
      new MyFrame();
     }
    }               
    3.给Button对象添加监听:
    myButton.addActionListener(new buttonListener());
    新建窗口对象:
      

  4.   

    JFrame jf = new JFrame();
    jf.setValuable(true);//或jf.show();
      

  5.   

    这个很难吗?button.addActionListener(new ActionEvent(){
       public void performAction(Event e){
          NeedShowFrame frame = new NeedShowFrame();
          frame.setVisable(true);
          frame.setSize(100, 100);
       }
    });
      

  6.   


    更正下:
    button.addActionListener(new ActionListener(){
      public void performAction(ActionEvent e){
          NeedShowFrame frame = new NeedShowFrame();
          frame.setVisable(true);
          frame.setSize(100, 100);
      }
    });
      

  7.   

    swt-designer好像只能做swt吧。我记得swt中是shell。
      

  8.   

    其实如果只是要弹一般的对话框,可以尝试使用JOptionPanel里面的showMessageDialog等方法,简单快捷~
      

  9.   

    在按钮的button_click事件中写上如下代码:
    form f=new Form();
    f.show()
      

  10.   

    new Frame()
    前一个Frame setvisible(false)
