Java GUI

Frame

package gui.lesson01;

import java.awt.Color;
import java.awt.Frame;

public class FrameTest {
	public static void main(String[] args) {
		Frame frame=new Frame("Java窗口");
		//设置可见性
		frame.setVisible(true);
		//设置窗口大小
		frame.setSize(400, 400);
		//设置背景颜色
		frame.setBackground(new Color(200,200,200));
		//弹出的初始位置
		frame.setLocation(100,100);
		//设置大小固定
		frame.setResizable(false);
		
	}
}

封装

package gui.lesson01;

import java.awt.Color;
import java.awt.Frame;

public class FrameTest {
	public static void main(String[] args) {
		Frame frame=new Frame("Java窗口");
		//设置可见性
		frame.setVisible(true);
		//设置窗口大小
		frame.setSize(400, 400);

		//弹出的初始位置
		frame.setLocation(100,100);
		//设置大小固定

	}
}

Panel

package gui.lesson01;

import java.awt.Color;
import java.awt.Frame;
import java.awt.Panel;

		//监听事件
		//适配器模式

		Frame frame=new Frame();
		Button button1=new Button("one");
		Button button2=new Button("two");
		Button button3=new Button("three");
		//设置为流式布局
		frame.setLayout(new FlowLayout(FlowLayout.LEFT));
		frame.setSize(300, 300);
		frame.setVisible(true);
		frame.add(button1);
		frame.add(button2);
		frame.add(button3);
		frame.addWindowListener(new WindowAdapter() {
			//窗口点击关闭的时候要做的事情
			@Override
			public void windowClosing(WindowEvent e) {
				// TODO Auto-generated method stub
				//super.windowClosing(e);
				System.exit(0);
			}
		});
	}
}
