툴팁 달기 code

import java.util.Calendar;
import java.util.Random;
import java.util.Vector;
import java.awt.*;


public class ToolTipEx extends JFrame{
	private Container contentPane;
	
	private void createToolBar() {
		JToolBar bar = new JToolBar("Kitae Menu");
		bar.setBackground(Color.LIGHT_GRAY);
		
		JButton newBtn = new JButton("New");
		newBtn.setToolTipText("파일을 생성합니다.");
		bar.add(newBtn);
		
		JButton openBtn = new JButton(new ImageIcon("C:\\\\Temp/lion.gif"));
		openBtn.setToolTipText("이건 라이언이다.");
		bar.add(openBtn);
		
		bar.addSeparator();
		
		JTextField tf = new JTextField("text field");
		tf.setToolTipText("찾고자 하는 문자열을 입력하세요.");
		bar.add(tf);
			
		contentPane.add(bar,BorderLayout.NORTH);
	}
	
	ToolTipEx(){
		setTitle("14장 연습하기");
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		contentPane = getContentPane();
		createToolBar();
		
		setSize(400, 400); 
		setVisible(true); 
	}
	
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		new ToolTipEx();
	}

}

 

툴팁 시간 제어하기는 다음 코드를 이용하면 된다.

 

ToolTipManager m = ToolTipManager.sharedInstance();
m.setInitialDelay(0);
m.setDismissDelay(3000);

 

JDialog 를 상속받아서 다이얼로그를 만드는 code

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import java.awt.event.MouseMotionListener;
import java.util.Calendar;
import java.util.Random;
import java.util.Vector;
import java.awt.*;


class MyDialog extends JDialog{
	private JTextField tf = new JTextField(10);
	private JButton okButton = new JButton("OK");
	
	MyDialog(JFrame frame, String title){
		super(frame, title);
		setLayout(new FlowLayout());
		add(tf);
		add(okButton);
		setSize(200, 100);
		
		okButton.addActionListener(new ActionListener() {
			public void actionPerformed(ActionEvent e) {
				setVisible(false);
			}
		});
	}
	
}

public class DialogEx extends JFrame{
	private MyDialog dialog;
	
	DialogEx(){
		setTitle("14장 연습하기");
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		JButton btn = new JButton("Show Dialog");
		
		dialog = new MyDialog(this, "Test Dialog");
		
		btn.addActionListener(new ActionListener() {
			public void actionPerformed(ActionEvent e) {
				dialog.setVisible(true);
			}
		});
		
		getContentPane().add(btn);
		setSize(400, 400); 
		setVisible(true); 
	}
	
	public static void main(String[] args) {
		// TODO Auto-generated method stub

	}

}

 

다이얼로그의 타입은 모달(Modal)과 모달리스(Modeless)두 가지가 있다.

 

Modal Type => 다이얼로그가 일단 출력되면 다이얼로그를 닫기 전에는 다른 작업을 전혀 할 수 없다.

즉, 사용자 입력을 독점하는 타입을 말함

 

Modeless =>  다른 창과 모달리스 다이얼로그가 각자 독립적으로 실행이 가능하다.

 

모달 다이얼로그로부터 사용자의 입력 값을 알아내는 Code

 

package Part14;

import javax.swing.*; // JFrame
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;
import java.awt.*; // Container
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.awt.event.MouseMotionAdapter;
import java.awt.event.MouseMotionListener;
import java.util.Calendar;
import java.util.Random;
import java.util.Vector;
import java.awt.*;


class MyDialog extends JDialog{
	private JTextField tf = new JTextField(10);
	private JButton okButton = new JButton("OK");
	
	MyDialog(JFrame frame, String title){
		super(frame, title, true); // boolean 추가로 Modal(true), Modeless(false)를 결정한다.
		setLayout(new FlowLayout());
		add(tf);
		add(okButton);
		setSize(200, 100);
		
		okButton.addActionListener(new ActionListener() {
			public void actionPerformed(ActionEvent e) {
				setVisible(false);
			}
		});
	}
	
	public String getInput() {
		return tf.getText();
	}
	
}

public class DialogEx extends JFrame{
	private MyDialog dialog;
	
	DialogEx(){
		setTitle("14장 연습하기");
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		JButton btn = new JButton("Show Dialog");
		
		dialog = new MyDialog(this, "Test Dialog");
		
		btn.addActionListener(new ActionListener() {
			public void actionPerformed(ActionEvent e) {
				dialog.setVisible(true);
				String text = dialog.getInput();
				btn.setText(text);
			}
		});
		
		getContentPane().add(btn);
		setSize(400, 400); 
		setVisible(true); 
	}
	
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		new DialogEx();
	}

}

 

Modal Type 인 경우 => 입력하고 OK 버튼을 클릭하면 해당 Dialog가 종료되면서 받아온 String 으로 버튼의 text가 변경된다. 

 

 

Modeless Type 인 경우 => 독립적으로 실행되므로 바로 Dialog의 TextField의 문자열을 가져와서 바로 적용된다.
