当前位置 博文首页 > AiY..的博客：Frame-Pannel-Button综合
1、Frame已经介绍过，不懂可以参考 博客-Frame
2、Pannel：用在Frame中的，类似一种面板放在Frame框架中，使用时需要配合Frame
因为生成的Frame框不能X掉，写下面这个就可以把生成的界面X掉，不至于强行停止程序
frame.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
package 狂神说__AWT;
import java.awt.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
//面板
public class TestPannel {
public static void main(String[] args) {
Frame frame=new Frame();
Panel panel=new Panel();
frame.setLayout(null);
//框架的坐标大小颜色
frame.setBounds(300,300,400,400);
frame.setBackground(new Color(133, 240, 192));
//在frame框架中设置面板
panel.setBounds(100,100,100,100);
panel.setBackground(new Color(255, 18, 30));
//框架中加入面板
frame.add(panel);
frame.setVisible(true);
frame.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
}
}
3、Button按钮有三种类型：
（1）FlowLayout 流式布局，指定按钮在左边、右边或者中间
package 狂神说__AWT;
import java.awt.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
//Layout布局
public class TestFlowLayout {
public static void main(String[] args) {
Frame frame = new Frame();
frame.setVisible(true);
frame.setBounds(200,200,400,400);
//按钮
Button button1 = new Button("button1");
Button button2 = new Button("button2");
Button button3 = new Button("button3");
frame.add(button1);
frame.add(button2);
frame.add(button3);
//流式布局
//frame.setLayout(new FlowLayout()); //中心
//frame.setLayout(new FlowLayout(FlowLayout.LEFT)); //左边
frame.setLayout(new FlowLayout(FlowLayout.RIGHT)); //左边
frame.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
}
}
（2）BorderLayout 东西南北布局
package 狂神说__AWT;
import java.awt.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
public class TestBorderLayout {
public static void main(String[] args) {
Frame frame = new Frame("TestBorderLayout");
frame.setVisible(true);
frame.setBounds(200,200,400,400);
//东西南北分布
Button east = new Button("East");
Button wast = new Button("Wast");
Button south = new Button("South");
Button north = new Button("North");
Button center = new Button("Center");
frame.add(east,BorderLayout.EAST);
frame.add(wast,BorderLayout.WEST);
frame.add(south,BorderLayout.SOUTH);
frame.add(north,BorderLayout.NORTH);
frame.add(center,BorderLayout.CENTER);
frame.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
}
}
（3）GridLayout 表格布局
package 狂神说__AWT;
import java.awt.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
public class TestGridLayout {
public static void main(String[] args) {
Frame frame = new Frame();
frame.setBounds(200,200,400,400);
frame.setVisible(true);
Button button1 = new Button("button1");
Button button2 = new Button("button2");
Button button3 = new Button("button3");
Button button4 = new Button("button4");
Button button5 = new Button("button5");
Button button6 = new Button("button6");
//表格布局
frame.setLayout(new GridLayout(3,2));//三行两列
frame.add(button1);
frame.add(button2);
frame.add(button3);
frame.add(button4);
frame.add(button5);
frame.add(button6);
frame.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
}
}
综合：用布局如下的界面：
package 狂神说__AWT;
import java.awt.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
public class FrameComprehensive {
public static void main(String[] args) {
Frame frame = new Frame();
Panel panel1 = new Panel(new BorderLayout
