GUI布局

打开多个对话框

package demo01;import java.awt.Container;
import java.awt.Label;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JFrame;public class DialogDemo01 extends JDialog{public DialogDemo01(JFrame jframe) {//super(jframe,true);super(jframe,false);this.setBounds(100,100,500,200);Container container1=this.getContentPane();container1.setLayout(null);//container.add(new Label("大数据五班"));JButton button1=new JButton("五班");button1.setBounds(30,30,200,50);container1.add(button1);}public static void main(String[] args) {JFrame j=new JFrame();j.setVisible(true);j.setBounds(100,100,700,500);j.setDefaultCloseOperation(EXIT_ON_CLOSE);Container container=j.getContentPane();container.setLayout(null);JButton button=new JButton("登录");button.setBounds(30,30,200,50);button.addActionListener(new ActionListener(){@Overridepublic void actionPerformed(ActionEvent e) {DialogDemo01 s=new DialogDemo01(j);s.setVisible(true);System.out.println("我被点击");}});container.add(button);}
}

普通方位

package demo02;import java.awt.Container;
import java.awt.GridLayout;import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
//面板作为容器不能单独存在，必须放在其他容器里面   JFrame，JDialog
public class JPaneDemo extends JFrame {public JPaneDemo() {Container container=this.getContentPane();container.setLayout(new GridLayout(2,1,10,10));JPanel panel=new JPanel(new GridLayout(1,3));panel.add(new JButton("1"));panel.add(new JButton("2"));panel.add(new JButton("3"));container.add(panel);this.setDefaultCloseOperation(EXIT_ON_CLOSE);this.setVisible(true);this.setBounds(100,100,500,500);}public static void main(String[] args) {new JPaneDemo();}
}

左右滑动

package demo02;import java.awt.Container;
import java.awt.GridLayout;import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;public class JScrollDemo extends JFrame{public JScrollDemo() {Container container=this.getContentPane();//文本域JTextArea textarea=new JTextArea(20,50);textarea.setText("大数据五班");//scroll面板JScrollPane scrollpane=new JScrollPane(textarea);//JPanel scrollpane=new JPanel();//scrollpane.add(textarea);container.add(scrollpane);this.setDefaultCloseOperation(EXIT_ON_CLOSE);this.setVisible(true);this.setBounds(100,100,500,500);}public static void main(String[] args) {new JScrollDemo();}
}

两行三列

package demo03;import java.awt.FlowLayout;
import java.awt.GridLayout;import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.WindowConstants;public class TestGrid {public static void main(String[] args) {JFrame j=new JFrame();j.setVisible(true);j.setBounds(100,100,700,500);j.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);j.setLayout(new GridLayout(3,2));JButton button1=new JButton("button1");button1.setSize(50,50);JButton button2=new JButton("button2");button2.setSize(50,50);JButton button3=new JButton("button3");JButton button4=new JButton("button4");JButton button5=new JButton("button5");//JButton button6=new JButton("button6");j.add(button1);j.add(button2);j.add(button3);j.add(button4);j.add(button5);//j.add(button6);//j.pack();}
}

上下左右（东西南北）

package demo03;import java.awt.BorderLayout;
import java.awt.FlowLayout;
import java.awt.GridLayout;import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.WindowConstants;public class TestBorderLayout {public static void main(String[] args) {JFrame j=new JFrame();j.setVisible(true);j.setBounds(100,100,700,500);j.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);JButton east=new JButton("east");JButton west=new JButton("west");JButton south=new JButton("south");JButton north=new JButton("north");JButton center=new JButton("居中");j.add(east,BorderLayout.EAST);j.add(west,BorderLayout.WEST);j.add(south,BorderLayout.SOUTH);j.add(north,BorderLayout.NORTH);j.add(center,BorderLayout.CENTER);}
}
