如何将JPanel添加到JFrame [英] How to add JPanel in to JFrame

问题描述

你好，
我在Java中有2个课程.
1)扩展Jframe的类
2)另一种扩展JPanel

我尝试在JFram类中添加JPanel，它看起来像这样:

Hello,
i have 2 classes in java.
1)a class that extends Jframe
2)another that extends JPanel

I try to add the JPanel in the JFram class , it looks something like this:

public static void main(String args[]) { // the main is in the JFram class
        Othello Oth= new Othello();    // instance of the JFram class
        Oth.setLocation(250, 150);
        OthelloBoard OB = new OthelloBoard();     // instance of JPanel class
        Oth.add(OB);
        Oth.setVisible(true);

但是只显示了JFrame，而且看来我添加的JPanel并没有进入JFrame(我正在使用NetBeans).

我该如何解决这个问题?

谢谢...

but only the JFrame got shown and it seems that the JPanel i added did not go onto the JFrame (i am using NetBeans).

How can I solve this problem??

Thank you...

我应用了santosh dhanawade解决方案，但没有成功.

这是两个主要方面:

Othello.Java

Can any one help me please ..

I applied the santosh dhanawade solution but it didn''t work.

this is the two main clasess:

Othello.Java

public class Othello extends javax.swing.JFrame {

    OthelloBoard OB;

    /** Creates new form Othello */

    public Othello() {

        initComponents();
        OB = new OthelloBoard();
        add(OB,BorderLayout.CENTER);
        setVisible(true);
}

public static void main(String args[]) {


            Othello Oth= new Othello();
            Oth.setLocation(250, 150);




    }
