我的onclick想要得到的JPanel的名称是在JFrame present [英] onclick i want to get the name of the JPanel that is present on the JFrame

问题描述

下面是我尝试实现，但中提到的其行给出的错误;这是因为函数不列入得到其中component.getName返回（）是...
    字符串名称=新的String（）;

  mntmOneToOne.addMouseListener（新MouseAdapter（）
               {
                    @覆盖
                    公共无效的mouseClicked（的MouseEvent arg0中）
                    {
                        字符串名称=新的String（）;
                        诠释计数= arg0.getClickCount（）;
                        如果（计数== 1）
                        {
                          组分面板=（成分）arg0.getSource（）;
                          的System.out.println（panel.getName（））;
                        }                    }
                 }）;
 

解决方案

通过的MouseEvents的的getSource（）方法获取点击的对象。然后调用它的的getName（）方法。

  mntmOneToOne.addMouseListener（新MouseAdapter（）{
     @覆盖
     公共无效的mouseClicked（的MouseEvent的MouseEvent）{
         诠释计数= mouseEvent.getClickCount（）;
         如果（计数== 1）{
           组分面板=（成分）mouseEvent.getSource（）;
           名称= panel.getName（）;
         }
     }
}）;
 

Below is what im trying to implement but its giving error on the line mentioned ; this is because the function doesnot get which Component.getName() is of ... String name=new String();

                mntmOneToOne.addMouseListener(new MouseAdapter()
               {
                    @Override
                    public void mouseClicked(MouseEvent arg0)
                    {
                        String name=new String();
                        int count = arg0.getClickCount();
                        if (count == 1)
                        {
                          Component panel = (Component) arg0.getSource();   


                          System.out.println(panel.getName());
                        }

                    }
                 });

解决方案

Get the clicked object via your MouseEvent's getSource() method. Then call its getName() method.

mntmOneToOne.addMouseListener(new MouseAdapter() {
     @Override
     public void mouseClicked(MouseEvent mouseEvent) {
         int count = mouseEvent.getClickCount();
         if (count == 1) {
           Component panel = (Component)mouseEvent.getSource();
           name = panel.getName(); 
         }
     }
});
