推荐答案

这将迭代JFrame的contentPane内部的所有组件，并将它们打印到控制台:

this will iterate through all components inside your JFrame's contentPane and print them to the console:

public void listAllComponentsIn(Container parent)
{
    for (Component c : parent.getComponents())
    {
        System.out.println(c.toString());

        if (c instanceof Container)
            listAllComponentsIn((Container)c);
    }
}

public static void main(String[] args)
{
    JFrame jframe = new JFrame();

    /* ... */

    listAllComponentsIn(jframe.getContentPane());
}
