问题描述
我有一个将 JPanel 添加到 JFrame 的程序:
I have a program in which a JPanel is added to a JFrame:
public class Test{ Test2 test = new Test2(); JFrame frame = new JFrame(); Test(){ ... frame.setLayout(new BorderLayout()); frame.add(test, BorderLayout.CENTER); ... } //main ... } public class Test2{ JPanel test2 = new JPanel(); Test2(){ ... } }我收到一条错误消息,要求我将面板"类型更改为组件".我要修复这个错误吗?它要我做:Component panel = new Component();
I get an error asking me to change type of 'panel' to 'component'. I do I fix this error? It wants me to do: Component panel = new Component();
推荐答案 public class Test{ Test2 test = new Test2(); JFrame frame = new JFrame(); Test(){ ... frame.setLayout(new BorderLayout()); frame.add(test, BorderLayout.CENTER); ... } //main ... } //public class Test2{ public class Test2 extends JPanel { //JPanel test2 = new JPanel(); Test2(){ ... }更多推荐
