JAVA GUI学习记录

1.基本界面

import java.awt.*;
import java.awt.event.*;
import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JFrame;
import javax.swing.JLabel;

public class GUI 
{	
	public static void main(String[] args) 
	{
    	JFrame basic_frame= new JFrame();//frame窗口
		Panel basic_panel=new Panel();//panel面板
		basic_frame.add(basic_panel);
		Color c_background=new Color(255,255,205);//设置颜色
		basic_panel.setBackground(c_background);//将颜色设置为面板颜色(背景颜色)
		Color c_button0=new Color(0x66ccff);
		basic_panel.setLayout(null);//布局类型
		basic_frame.setBounds(256,256,512,288);//窗口相关设置
		basic_frame.setVisible(true);
		basic_frame.validate();

		Button button0=new Button("nanijibamono");//button按键
		button0.setBounds(208,96,90,25);//设置按键位置以及大小
		button0.setBackground(c_button0);//设置按键颜色
		button0.addActionListener(button0_behavour);//按键事件监听
		basic_panel.add(button0);//在面板中加入按键
		
		Choice choice0=new Choice();//设置下拉选项
		choice0.setBounds(208,144,60,20);
		choice0.add("wly");
		choice0.add("wly~");
		basic_panel.add(choice0);//添加按钮

        basic_frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//关闭
    }
}

2.事件监听


	public static class Monitor implements ActionListener//按键按下,如果choice为0则打开新窗口
	{
		public void actionPerformed(ActionEvent e)
		{
			JFrame frame0=new JFrame();
			Panel panel0=new Panel();
			frame0.add(panel0);
			JLabel label00=new JLabel("什么X东西",JLabel.CENTER);
			frame0.add(label00);
			frame0.setBounds(256,256,128,64);
			if(tempnum==0)
			{
				frame0.setVisible(true);
			}
		}
	}

		choice0.addItemListener(new ItemListener()//选项改变时得到选项的值
		{
			public void itemStateChanged(ItemEvent e)
			{
				tempnum=choice0.getSelectedIndex();
			}
		});
