Java Basic : day 14 - AWT & SWING 7 : Window Change

Window Change

화면 전환 방법

1. dispose() 

- 현재 화면이 사라지는 메소드. 코드 구현 후 다음 화면을 생성해준다.

< 예제 >

package day15.Lecture01_AWT.test10_windowChanger1;

import java.awt.Button;
import java.awt.Color;
import java.awt.Frame;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowEvent;
import java.awt.event.WindowListener;

public class WindowOne extends Frame implements WindowListener {

	public WindowOne() {
		// TODO Auto-generated constructor stub
	
		setLayout(null);
		
		Button btn = new Button("move win");
		btn.setBounds(100, 100, 100, 30);
		add(btn);
		btn.addActionListener(new ActionListener() {
			
			@Override
			public void actionPerformed(ActionEvent e) {
				// TODO Auto-generated method stub
				
				// System.exit(0)
				// 위의 코드는 프로세스도 꺼지므로 사용하면 안된다.
				// dispose 이용
				dispose();
				
				// 그다음 윈도우를 켜준다.
				new windowTwo();
			}
		});
		
		
		
		
		
		
		
		setBackground(Color.red);
		setSize(640,480);
		setLocation(0, 0);
		addWindowListener(this);
		setVisible(true);

	
	}
	@Override
	public void windowOpened(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowClosing(WindowEvent e) {
		// TODO Auto-generated method stub
		System.exit(0);
	}

	@Override
	public void windowClosed(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowIconified(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowDeiconified(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowActivated(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowDeactivated(WindowEvent e) {
		// TODO Auto-generated method stub

	}

}

 

 

 

 

2. 싱글톤을 이용해서 setVisible 값을 전환해주기

 

1) 싱글톤 클래스를 만들고 생성자에 전환할 화면을 구성하고 있는 클래스를 생성해준다. 

   화면 전환할 객체들은 설계시 모두 setVisible을 false로 바꾼다.

package day15.Lecture01_AWT.test11_windowChanger2;

public class Singleton {
	
	private static Singleton singleton =null;
	public WindowOne win1;
	public windowTwo win2;
	
	private Singleton() {
		win1 = new WindowOne();
		win2 = new windowTwo();
	}
	
	public static Singleton getInstane() {
		if(singleton == null) singleton = new Singleton();
		return singleton;
	}
	
	
}

 

2) 화면 1의 화면 전환 버튼을 만들어 주고,

    버튼을 누르면 싱글톤 객체를 불러온 뒤 setVisible 값을 바꾸어 준다.

package day15.Lecture01_AWT.test11_windowChanger2;

import java.awt.Button;
import java.awt.Color;
import java.awt.Frame;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowEvent;
import java.awt.event.WindowListener;


// Window changew
public class WindowOne extends Frame implements WindowListener {

	public WindowOne() {
		// TODO Auto-generated constructor stub
	
		setLayout(null);
		
		Button btn = new Button("move win");
		btn.setBounds(100, 100, 100, 30);
		add(btn);
		btn.addActionListener(new ActionListener() {
			
			@Override
			public void actionPerformed(ActionEvent e) {
			
				Singleton.getInstane().win1.setVisible(false);
				Singleton.getInstane().win2.setVisible(true);
				
			}
		});
		
		
		
		
		
		
		
		setBackground(Color.red);
		setSize(640,480);
		setLocation(0, 0);
		addWindowListener(this);
		setVisible(false);	// singleton이 visible제어함

	
	}
	@Override
	public void windowOpened(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowClosing(WindowEvent e) {
		// TODO Auto-generated method stub
		System.exit(0);
	}

	@Override
	public void windowClosed(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowIconified(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowDeiconified(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowActivated(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowDeactivated(WindowEvent e) {
		// TODO Auto-generated method stub

	}

}

3) 마찬가지로 전환할 화면의 클래스도 설계해준다.

   setVisible은 싱글톤이 제어하도록 꺼준다.

package day15.Lecture01_AWT.test11_windowChanger2;

import java.awt.Color;
import java.awt.Frame;
import java.awt.event.WindowEvent;
import java.awt.event.WindowListener;

public class windowTwo extends Frame implements WindowListener {

	public windowTwo() {
		
		setBackground(Color.BLUE);
		setSize(800, 600);
		setLocation(0, 0);
		addWindowListener(this);
		setVisible(false); // singleton이 visible제어함

	}
	@Override
	public void windowOpened(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowClosing(WindowEvent e) {
		// TODO Auto-generated method stub
		System.exit(0);
	}

	@Override
	public void windowClosed(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowIconified(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowDeiconified(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowActivated(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowDeactivated(WindowEvent e) {
		// TODO Auto-generated method stub

	}

}

 

 

 

 

 

 

 

 

3. 하나의 클래스에 패널로 화면 바꿔주기

- remove() 메소드를 이용해서 패널을 바꾸어 준다.

package day15.Lecture01_AWT.test12_windowChanger3;

import java.awt.Button;
import java.awt.Color;
import java.awt.FlowLayout;
import java.awt.Frame;
import java.awt.Panel;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowEvent;
import java.awt.event.WindowListener;

import javax.swing.JOptionPane;


// Window changew
public class WindowOne extends Frame implements WindowListener {

	public WindowOne() {
		// TODO Auto-generated constructor stub
	
		setLayout(new FlowLayout());
		Panel p1 = new Panel();
		Panel p2 = new Panel();
		
		p1.setBackground(Color.black);
		p1.setLayout(null);
		p1.setBounds(0, 0, 640, 480);
		add(p1);
		
		p2.setBackground(Color.blue);
		p2.setBounds(0, 0, 640, 480);
		
		
		
		Button btn = new Button("move win");
		btn.setBounds(100, 100, 100, 30);
		p1.add(btn);
		btn.addActionListener(new ActionListener() {
			
			@Override
			public void actionPerformed(ActionEvent e) {
				remove(p1);
				add(p2);
				
			}
		});
		
		
		Button btn2 = new Button("move win2");
		btn2.setBounds(100, 100, 100, 30);
		p2.add(btn2);
		btn2.addActionListener(new ActionListener() {

			@Override
			public void actionPerformed(ActionEvent e) {
				// TODO Auto-generated method stub
				remove(p2);
				add(p1);
			}
		});
			
		
		
		
		
		
		setBackground(Color.red);
		setSize(640,480);
		setLocation(0, 0);
		addWindowListener(this);
		setVisible(true);	// singleton이 visible제어함

	
	}
	@Override
	public void windowOpened(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowClosing(WindowEvent e) {
		// TODO Auto-generated method stub
		System.exit(0);
	}

	@Override
	public void windowClosed(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowIconified(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowDeiconified(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowActivated(WindowEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void windowDeactivated(WindowEvent e) {
		// TODO Auto-generated method stub

	}

}
