我的代码:
/**
* byq.java
* done by symbol windows风格
*/
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
public class byq extends JFrame
{
//定义
JButton Button1 = new JButton("开始编译"); //按钮
JTextArea textArea1 = new JTextArea ("在这里写代码",30,60);
JTextArea textArea2 = new JTextArea ("调试信息",30,60);
JLabel label1 = new JLabel("代码输入:"); //不是按钮,是静态文本
JLabel label2 = new JLabel("调试信息"); //不是按钮,是静态文本
//JScrollPane scrollPane1 = new JScrollPane(textArea1);
//JScrollPane scrollPane2 = new JScrollPane(textArea2);
public byq()
{
JScrollPane scrollPane1 = new JScrollPane(textArea1);//不写这里textArea不能用,写了还是不能用
JScrollPane scrollPane2 = new JScrollPane(textArea2);
//初始化
//getContentPane().setLayout(new java.awt.FlowLayout());//大小自动适合
getContentPane().setLayout( null );
textArea1.setLineWrap(true);
textArea2.setLineWrap(true);
getContentPane().add(textArea1);
getContentPane().add(textArea2);
getContentPane().add(Button1);
getContentPane().add(label1);
getContentPane().add(label2);
getContentPane().add(scrollPane1);
getContentPane().add(scrollPane2);
//颜色
getContentPane().setBackground(Color.GREEN);
label1.setForeground(Color.RED);
label2.setForeground(Color.RED);
Button1.setForeground(Color.red);
//方位大小
label1.setBounds(30,30,180,30);
label2.setBounds(30,300,180,30);
Button1.setBounds( 680, 600, 100,60 );
//textArea1.setBounds(30, 60, 700, 200);
//textArea2.setBounds(30, 330, 700, 200);
scrollPane1.setBounds(30, 60, 700, 200);
scrollPane2.setBounds(30, 330, 700, 200);
/* 为一般按钮添加动作监听器 */
Button1.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent ae)
{
JOptionPane.showMessageDialog(null,"开始编译","标题",JOptionPane.INFORMATION_MESSAGE);
System.exit(0);
}
});
setSize(800, 700);
System.out.println("this is my first window");
}
public static void main(String[] args)
{
try
{
UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
}
catch(Exception e)
{
e.printStackTrace();
}
byq win = new byq();
win.show();
}
}
