1. JDialog

하나의 프레임에 다이얼로그가 여러개

1) 만드는 방법(부모창 / 자식창)

JDialog 창의 main메서드 안의 코드를 부모창인 JFrame에서 필요한 순간에 넣는다.

 

다음은 자식창인 JDialog 만드는 방법이다.

이렇게 클래스를 만들 때 JDialog를 extends 하도록 만든다.

 

 

그리고 JDialog의 main 메서드내의 코드를

다음과 같이 JFrame에서 필요한 순간에 넣는다. 

(JDialog에서는 main 메서드를 주석처리한다.)

JButton btnNewButton = new JButton("New button");
btnNewButton.addMouseListener(new MouseAdapter() {
    @Override
    public void mouseClicked(MouseEvent arg0) {
        JDialogEx01 dialog = new JDialogEx01("초기 데이터");
        //setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 랑 비교
        dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);

        System.out.println("1");
        dialog.setModal(true);
        System.out.println("2");
        // 화면에의 제어를 자식창에 위임
        dialog.setVisible(true);
        // 부모창으로 변경 /  자식창 닫으면 부모창으로 변경됨
        System.out.println("3");
    }
});

 

 

그러면 다음과 같이 실행된다.

 

2) 부모창과 자식창이 데이터를 전달하는 방법

데이터 위치에 따라 조금씩 달라짐 (외부/ JFrame / JDialog)

JFrame(데이터) => JDialog(데이터)

           * 생성자

JDialog => JFrame

           * getter

 

1) 생성자 데이터 전달 - 초기 데이터

 

2) 특정한 시점 (getter)에 데이터 전달 - 변경 데이터

 

3) 자식 창 닫을 때 데이터 전달 - 완료 데이터

 

전체코드는 다음과 같다.

 

(1) JDialogMainEx01,java (부모)

import java.awt.BorderLayout;
import java.awt.EventQueue;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;

		EventQueue.invokeLater(new Runnable() {
			public void run() {
				try {
					JDialogMainEx01 frame = new JDialogMainEx01();
					frame.setVisible(true);
				} catch (Exception e) {
					e.printStackTrace();
				}
			}
		});
	}

	/**
	 * Create the frame.
	 */
	public JDialogMainEx01() {
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setBounds(100, 100, 450, 300);
		contentPane = new JPanel();
		contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
		setContentPane(contentPane);
		contentPane.setLayout(null);
		
		JButton btnNewButton = new JButton("New button");
		btnNewButton.addMouseListener(new MouseAdapter() {
			@Override
			public void mouseClicked(MouseEvent e) {
				// 생성자로 데이터 전달
				JDialogEx01 dialog = new JDialogEx01("초기 데이터");
				//setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 랑 비교
				dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);
				
				System.out.println("1");
				dialog.setModal(true);
				System.out.println("2");
				// 화면에의 제어를 자식창에 위임
				// setter, getter로 데이터 전달
				dialog.setShareData("변경 데이터");
				dialog.printShareData();
				
				// 여기에 정지된 상태가 들어간다. 
				dialog.setVisible(true);
				// 그래서 여길 기점으로 아래 위 데이터가 다른게 들어간다.
				
				// 부모창으로 변경 /  자식창 닫으면 부모창으로 변경됨
				System.out.println("3");
				System.out.println(dialog.getShareData());
			}
		});
		btnNewButton.setBounds(14, 12, 105, 27);
		contentPane.add(btnNewButton);
	}

}

 

(2) JDialogEx01.java (자식)

import java.awt.BorderLayout;
import java.awt.FlowLayout;

import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;

	// setter랑 getter로 데이터 전달
	public void setShareData(String shareData) {
		this.shareData = shareData;
	}
	
	public String getShareData() {
		return shareData;
	}
	
	// setter, getter 데이터 부르는 메서드
	public void printShareData() {
		System.out.println(this.shareData);
	}

	/**
	 * Launch the application.
	 */
//	public static void main(String[] args) {
//		try {
//			JDialogEx01 dialog = new JDialogEx01();
//			dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);
//			dialog.setVisible(true);
//		} catch (Exception e) {
//			e.printStackTrace();
//		}
//	}

	/**
	 * Create the dialog.
	 */
	public JDialogEx01() {
		setBounds(100, 100, 450, 300);
		getContentPane().setLayout(new BorderLayout());
		contentPanel.setLayout(new FlowLayout());
		contentPanel.setBorder(new EmptyBorder(5, 5, 5, 5));
		getContentPane().add(contentPanel, BorderLayout.CENTER);
		{
			JPanel buttonPane = new JPanel();
			buttonPane.setLayout(new FlowLayout(FlowLayout.RIGHT));
			getContentPane().add(buttonPane, BorderLayout.SOUTH);
			{
				JButton okButton = new JButton("OK");
				okButton.addMouseListener(new MouseAdapter() {
					@Override
					public void mouseClicked(MouseEvent e) {
						// 창닫기
						JDialogEx01.this.setShareData("완료된 데이터");
						JDialogEx01.this.dispose();
					}
				});
				okButton.setActionCommand("OK");
				buttonPane.add(okButton);
				getRootPane().setDefaultButton(okButton);
			}
			{
				JButton cancelButton = new JButton("Cancel");
				cancelButton.addMouseListener(new MouseAdapter() {
					@Override
					public void mouseClicked(MouseEvent e) {
						// 창닫기
						// this.dispose()하면 안됨 여기서 this는 MouseEvent이다.
						JDialogEx01.this.dispose();
					}
				});
				cancelButton.setActionCommand("Cancel");
				buttonPane.add(cancelButton);
			}
		}
	}
	
	// 생성자로 데이터 전달
	// 생성자 오버로딩 / JDialogEx01() 안에 써도됨
	public JDialogEx01(String shareData) {
		this();
		this.shareData = shareData;
		 
		System.out.println("shareData : " + shareData);
	}

}

 

실행결과는 다음과 같다.

 

아이디 중복 검사, 주소 찾기 등에 쓰인다.

 

 

 

※ 주의할 점

1. modal

2. dialog에서 main하지마라 (frame에서 해야함)

3. 닫을 때 dispose() 해라

4. 데이터를 dialog에서 private정의해라

 

 

 

 

3) ColorChooser

				System.out.println(color);
			}
		});
		btnNewButton.setBounds(14, 12, 105, 27);
		contentPane.add(btnNewButton);
	}

}

             Adapter

                                  Event

 

* 발생시점

  • Window - JFrame / JDialog - 열기 닫기 , 비활성화, 최소화
  • Action - 마우스 클릭, 키보드 엔터, 아이템 선택
  • Mouse - 클릭, 오버, 영역내(밖)
  • Keyboard

 

3. Layout

모두 직접 코딩이 아닌 Design에서 그리는 형식이기 때문에 코드 업로드는 많이 하지 않는다.

1) BorderLayout

2) FlowLayout

LayoutEx01.java

panel넣고 안에 버튼 넣으면 버튼 크기에 따라서 panel사이즈 변함

밖은 boreder layout쓰고 안쪽은 absolute를 쓴다. 라고 보면 된다.

 

3) CardLayout

LayoutEx02.java

main패널을 만들고 그걸 card패널로 만든다.

그 안에 여러개의 패널을 만드는데 각각은 이름값을 가진다.

각각의 패널을 가져올 때 그 이름값을 가져온다. 

각각의 패널들을 카드들이라고 보고 main패널을 카드들을 가지는 패널로 봐라.

 

버튼클릭하면 이름에 일치하는 카드 패널 가져오기

((CardLayout)panel.getLayout()).show(panel, "name_194003486855500");

4) GridLayout

LayoutEx03.java

 

 

4. Event

 add이벤트종류Listener  → 이벤트종류Listener(이너클래스) → 각 이벤트별 메서드

'이벤트종류Listener' 만 치고 ctrl + enter 하면 자동 완성됨 

1) 이벤트 종류 : Window

EventEx01.java

import java.awt.BorderLayout;
import java.awt.EventQueue;
import java.awt.event.WindowEvent;
import java.awt.event.WindowListener;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;

	private JPanel contentPane;

				}
			}
		});
	}

	/**

	 */
	public EventEx01() {
		// 자동으로 닫기는 부분
		//setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

				System.out.println("windowDeactivated(WindowEvent e)");
			}
			
			@Override
			public void windowClosing(WindowEvent e) {
				System.out.println("windowClosing(WindowEvent e)");
			}
			
			@Override

				System.out.println("windowClosed(WindowEvent e)");
			}
			
			@Override
			public void windowActivated(WindowEvent e) {
				System.out.println("windowActivated(WindowEvent e)");
			}
		});
		
		setBounds(100, 100, 450, 300);
		contentPane = new JPanel();
		contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
		contentPane.setLayout(new BorderLayout(0, 0));
		setContentPane(contentPane);
	}

}

 

 

 

2) 이벤트 종류 : Mouse

버튼 마우스 클릭 이벤트 직접 주기

+ 이벤트종류Adapter   => 필요한 이벤트 메서드만 써줌

EventEx02.java

import java.awt.BorderLayout;
import java.awt.EventQueue;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;
import javax.swing.JButton;

public class EventEx02 extends JFrame {

	private JPanel contentPane;

	/**
	 * Launch the application.
	 */
	public static void main(String[] args) {
		EventQueue.invokeLater(new Runnable() {
			public void run() {
				try {
					EventEx02 frame = new EventEx02();
					frame.setVisible(true);
				} catch (Exception e) {
					e.printStackTrace();
				}
			}
		});
	}

	/**
	 * Create the frame.
	 */
	public EventEx02() {
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setBounds(100, 100, 450, 300);
		contentPane = new JPanel();
		contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
		setContentPane(contentPane);
		contentPane.setLayout(null);
		
		JButton btnNewButton = new JButton("New button");
		btnNewButton.addMouseListener(new MouseListener() {
			
			@Override
			public void mouseReleased(MouseEvent e) {
				System.out.println("mouseReleased(MouseEvent e)");
			}
			
			@Override
			public void mousePressed(MouseEvent e) {
				System.out.println("mousePressed(MouseEvent e)");
			}
			
			@Override
			public void mouseExited(MouseEvent e) {
				System.out.println("mouseExited(MouseEvent e)");
			}
			
			@Override
			public void mouseEntered(MouseEvent e) {
				System.out.println("mouseEntered(MouseEvent e)");
			}
			
			@Override
			public void mouseClicked(MouseEvent e) {
				// '클릭되었다'는 뜻으로 눌렀을때가 아니라 뗐을 때  나옴
				System.out.println("mouseClicked(MouseEvent e)");
			}
		});
		btnNewButton.setBounds(14, 12, 105, 27);
		contentPane.add(btnNewButton);
		
		JButton btnNewButton_1 = new JButton("New button");
		
		// addMouseListener -> MouseListener(전체 구현)   => 귀찮다
		// 그래서                       -> MouseAdapter(이미위에걸 다 구해놓은거라서)  => 필요메서드만 
		btnNewButton_1.addMouseListener(new MouseAdapter() {
			@Override
			public void mouseClicked(MouseEvent e) {
				System.out.println("mouseClicked(MouseEvent e)");
			}
		});
		
		
		btnNewButton_1.setBounds(14, 51, 105, 27);
		contentPane.add(btnNewButton_1);
	}

}

 

버튼이 여러갠데 이벤트들을 같이 한번에 통합처리 하려면?

3) 이벤트 통합 처리  ->  인터페이스 클래스 사용

클래스에 implements MouseListener  해야한다.

그리고 메서드 추가는 아래처럼 한다.

 

 

그런다음 아래처럼 코드 추가하면 된다.

btn1.addMouseListener(this);
btn2.addMouseListener(this);

 

 

import java.awt.BorderLayout;
import java.awt.EventQueue;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;
import javax.swing.JButton;
import java.awt.event.ActionListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.awt.event.ActionEvent;

public class EventEx03 extends JFrame implements MouseListener{

	private JPanel contentPane;

	/**
	 * Launch the application.
	 */
	public static void main(String[] args) {
		EventQueue.invokeLater(new Runnable() {
			public void run() {
				try {
					EventEx03 frame = new EventEx03();
					frame.setVisible(true);
				} catch (Exception e) {
					e.printStackTrace();
				}
			}
		});
	}

	/**
	 * Create the frame.
	 */
	public EventEx03() {
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setBounds(100, 100, 450, 300);
		contentPane = new JPanel();
		contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
		setContentPane(contentPane);
		contentPane.setLayout(null);
		
		JButton btn1 = new JButton("버튼 1");
		btn1.setBounds(14, 12, 105, 27);
		btn1.addMouseListener(this);
		contentPane.add(btn1);
		
		JButton btn2 = new JButton("버튼 2");
		btn2.setBounds(14, 51, 105, 27);
		btn2.addMouseListener(this);
		contentPane.add(btn2);
	}

	
	
	// 마우스 이벤트 처리
	
	@Override
	public void mouseClicked(MouseEvent e) {
		// 버튼1인지 버튼2인지 구별 불가 
		//System.out.println("마우스 클릭");
		
		// 매우 많은게 출력됨
		//System.out.println("마우스 클릭" + e);
		// 위의 출력으로 알수 있는 값
		// 버튼이 클릭된 좌표값
		System.out.println(e.getX() + " / " + e.getY());
		// 소스 - 버튼에 대한 정보 (여기 text에 버튼 이름이 들어감)
		System.out.println(e.getSource());
		// 소스에서 text 발췌하기
		JButton btn = (JButton)e.getSource();
		System.out.println(btn.getText());
	}

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

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

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

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

}

 

 

4) 이벤트 통합 처리 -> 내부 인스턴스(스태틱) 클래스 사용

EventEx04.java

내부 인스턴스 클래스 사용

내부 스태틱 클래스 사용해도됨

class UserMouseEvent implements MouseListener

위와 같이 클래스내에 새로운 내부 인스턴스 클래스 UserMouseEvent 를 만들고 

 

호출할땐 다음과 같이 호출하면 된다.

btn1.addMouseListener(new UserMouseEvent());

btn2.addMouseListener(new UserMouseEvent());

 

import java.awt.BorderLayout;
import java.awt.EventQueue;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;
import javax.swing.JButton;
import java.awt.event.ActionListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.awt.event.ActionEvent;

public class EventEx04 extends JFrame {

	private JPanel contentPane;

	/**
	 * Launch the application.
	 */
	public static void main(String[] args) {
		EventQueue.invokeLater(new Runnable() {
			public void run() {
				try {
					EventEx04 frame = new EventEx04();
					frame.setVisible(true);
				} catch (Exception e) {
					e.printStackTrace();
				}
			}
		});
	}

	/**
	 * Create the frame.
	 */
	public EventEx04() {
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setBounds(100, 100, 450, 300);
		contentPane = new JPanel();
		contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
		setContentPane(contentPane);
		contentPane.setLayout(null);
		
		JButton btn1 = new JButton("버튼 1");
		btn1.setBounds(14, 12, 105, 27);
		btn1.addMouseListener(new UserMouseEvent());
		contentPane.add(btn1);
		
		JButton btn2 = new JButton("버튼 2");
		btn2.setBounds(14, 51, 105, 27);
		btn2.addMouseListener(new UserMouseEvent());
		contentPane.add(btn2);
	}
	
	// 내부 인스턴스(스태틱) 클래스
	class UserMouseEvent implements MouseListener{

		@Override
		public void mouseClicked(MouseEvent e) {
			System.out.println("마우스 클릭");
		}

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

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

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

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

 

 

여러 UI에서 클래스를 같이범용해서 쓴다면? 외부클래스화 해야한다.

 

 

 

 

※ 응용문제 

콤보박스 세개만들어서 리스트로 주소 출력되게 하기 (강사님 풀이는 월요일에!)

 

1) 주소를 리스트로 출력하기 

2) 주소를 테이블로 출력하기

3) 리스트로 출력 된 주소를 Dialog로 띄우고 받아와서 상세주소 입력받기 

 

이렇게 세가지 방법으로 구현하였다.

우편번호 검색을 위한 주소 데이터만 있어서 그걸로 주소 검색을 하듯 구현하였다.

메인메서드가 있는 UI클래스는 다 다르지만,

그 외의 클래스는 최대한 공유하게 만들었다.

 

다음은 각각 사용하는 클래스이다.

 

1) 주소를 리스트로 출력하기 

  • ZipcodeSearchListUI
  • ZipcodeComboModel
  • ZipcodeListModel
  • ZipcodeDAO
  • ZipcodeTO

2) 주소를 테이블로 출력하기

  • ZipcodeSearchTableUI
  • ZipcodeComboModel
  • ZipcodeTableModel
  • ZipcodeDAO
  • ZipcodeTO

3) 리스트로 출력 된 주소를 Dialog로 띄우고 받아와서 상세주소 입력받기 

  • ZipcodeSearchJFrameUI
  • ZipcodeSearchJDialogUI
  • ZipcodeComboModel
  • ZipcodeListModel
  • ZipcodeDAO
  • ZipcodeTO

1, 2, 3 번 모두 같은 ZipcodeDAO, ZipcodeTO를 사용한다.

1, 2, 3 번 모두 콤보박스를 사용하므로 같은 ZipcodeComboModel 을 사용한다.

리스트를 사용하는 1, 3 번은 ZipcodeListModel 을 사용하고,

테이블을 사용하는 2 번은 ZipcodeTableModel 을 사용한다.

 

아래 코드에서 중복되는 클래스는 처음 한번만 업로드 하였다.
