Java MDI(multiple Document Interface)form Application 만들기 using AWT/Swing

Java MDI(multiple Document Interface)form Application 만들기 using AWT/Swing

JavaMdiformApplication.zip

JAVA에서는 MDIForm이 기본적으로 제공 안됨.
유사한 모습으로 구현 가능한 것이 
Jframe( Parent ) - JinternalFrame ( Child ) 을 JdesktopPane 로 제어하는 프레임 구조임.

샘플화면

1. Java Project 생성

2. JFrame 생성 (Main 페이지)

3. JInternalFrame ( Child )

MDIFrame 수행을 위해서 메인 페이지에 메뉴추가 후 Child1,2,3을 실행 + 프로그래밍
Parent Page : JavaFrameMainPAge에서 메뉴추가

프로그래밍 

**javaFrameMainPAge 클래스에 JDesktopPane import.

import javax.swing.JDesktopPane; /*추가*/
import javax.swing.JInternalFrame;

@SuppressWarnings("serial")
public class javaFrameMainPAge extends JFrame {

        private JPanel contentPane;
        private JDesktopPane desktopPane ; /*추가 : 멀티문서 인터페이스 or 가상 데스크탑을 생성하는 컨테이너*/

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


**JDesktopPane 컨테이너에 JInternalFrame Add

private void mdiFormSetting(JInternalFrame oIframe)
        {               
                boolean bObj= true;
                JInternalFrame[] allFrames = desktopPane.getAllFrames();
               
                for(int i=0; i<allFrames.length; i++){
                        if(allFrames[i].getClass() ==  oIframe.getClass()){
                                bObj= false;
                                break;
                        }                       
                }
                
                if(bObj){
                        desktopPane.add(oIframe);
                        oIframe.setVisible(true);
                }
        }

**메뉴에서 Child1,2,3 페이지 호출

JMenuItem mntmChild = new JMenuItem("child1");
                mntmChild.addActionListener(new ActionListener() {
                        public void actionPerformed(ActionEvent e) {
                                
                                child1 obj = new child1();
                                mdiFormSetting(obj);
                        }
                });
                mnMditest.add(mntmChild);
