Kurze Frage - Applet in Applet starten?

[MartinDeluxe]

Hi. Ich hätte mal eine Frage. Ich hab mit Eclipse ein Paar Panel und Buttons erstellt und wollte nun mal fragen ob man in meinen Falle in jPanel2 ein Java-Applet starten kann indem man einen Button klickt. Ich möchte kein neues Fenster also keine neue URL aufrufen lassen. Hier erstmal mein Anfang:

import java.applet.Applet;
import java.awt.Dimension;

import javax.swing.JPanel;
import javax.swing.JButton;
import java.awt.FlowLayout;
import java.awt.BorderLayout;
import java.awt.GridBagLayout;
import javax.swing.BorderFactory;
import java.awt.Rectangle;


public class Innenfeld1 extends Applet {

	
	private static final long serialVersionUID = 1L;
	private JPanel jPanel = null;
	private JButton jButton = null;
	private JButton jButton1 = null;
	private JButton jButton2 = null;
	private JButton jButton3 = null;
	private JButton jButton4 = null;
	private JButton jButton5 = null;
	private JPanel jPanel1 = null;
	private JPanel jPanel2 = null;

	
	public Innenfeld1() {
		super();
		
	}

	
	public void init() {
        this.setLayout(new BorderLayout());
        this.setSize(new Dimension(510, 500));
        this.add(getJPanel(), BorderLayout.NORTH);
        this.add(getJPanel1(), BorderLayout.CENTER);
        
			
	}


	private JPanel getJPanel() {
		if (jPanel == null) {
			jPanel = new JPanel();
			jPanel.setLayout(new FlowLayout());
			jPanel.setBorder(BorderFactory.createLineBorder(java.awt.Color.black, 2));
			jPanel.add(getJButton(), null);
			jPanel.add(getJButton1(), null);
			jPanel.add(getJButton2(), null);
			jPanel.add(getJButton3(), null);
			jPanel.add(getJButton4(), null);
			jPanel.add(getJButton5(), null);
		}
		return jPanel;
	}

	
	private JButton getJButton() {
		if (jButton == null) {
			jButton = new JButton();
			jButton.setText("Button1");
			jButton.addActionListener(new java.awt.event.ActionListener() {
				public void actionPerformed(java.awt.event.ActionEvent e) {
					System.out.println("actionPerformed()"); // TODO Auto-generated Event stub actionPerformed()
				}
			});
		}
		return jButton;
	}

	
	private JButton getJButton1() {
		if (jButton1 == null) {
			jButton1 = new JButton();
			jButton1.setText("Button2");
			jButton1.addMouseListener(new java.awt.event.MouseAdapter() {
				public void mouseClicked(java.awt.event.MouseEvent e) {
					System.out.println("mouseClicked()"); // TODO Auto-generated Event stub actionPerformed()
					
				}
			});
		}
		return jButton1;
	}


	
	private JButton getJButton2() {
		if (jButton2 == null) {
			jButton2 = new JButton();
			jButton2.setText("Button3");
			jButton2.addActionListener(new java.awt.event.ActionListener() {
				public void actionPerformed(java.awt.event.ActionEvent e) {
					System.out.println("actionPerformed()"); // TODO Auto-generated Event stub actionPerformed()
				}
			});
		}
		return jButton2;
	}

	
	private JButton getJButton3() {
		if (jButton3 == null) {
			jButton3 = new JButton();
			jButton3.setText("Button4");
			jButton3.addActionListener(new java.awt.event.ActionListener() {
				public void actionPerformed(java.awt.event.ActionEvent e) {
					System.out.println("actionPerformed()"); // TODO Auto-generated Event stub actionPerformed()
				}
			});
		}
		return jButton3;
	}

	
	private JButton getJButton4() {
		if (jButton4 == null) {
			jButton4 = new JButton();
			jButton4.setText("Button5");
			jButton4.addActionListener(new java.awt.event.ActionListener() {
				public void actionPerformed(java.awt.event.ActionEvent e) {
					System.out.println("actionPerformed()"); // TODO Auto-generated Event stub actionPerformed()
				}
			});
		}
		return jButton4;
	}

	
	private JButton getJButton5() {
		if (jButton5 == null) {
			jButton5 = new JButton();
			jButton5.setText("Button6");
			jButton5.addActionListener(new java.awt.event.ActionListener() {
				public void actionPerformed(java.awt.event.ActionEvent e) {
					System.out.println("actionPerformed()"); // TODO Auto-generated Event stub actionPerformed()
				}
			});
		}
		return jButton5;
	}

	
	private JPanel getJPanel1() {
		if (jPanel1 == null) {
			jPanel1 = new JPanel();
			jPanel1.setLayout(null);
			jPanel1.add(getJPanel2(), null);
		}
		return jPanel1;
	}

	
	private JPanel getJPanel2() {
		if (jPanel2 == null) {
			jPanel2 = new JPanel();
			jPanel2.setLayout(new GridBagLayout());
			jPanel2.setBounds(new Rectangle(15, 15, 481, 432));
			jPanel2.setBorder(BorderFactory.createLineBorder(java.awt.Color.black, 2));
		}
		return jPanel2;
	}

}

Ich habe mich noch nicht lange damit beschäftigt also entschuldige ich mich gleich mal wenn ich irgendetwas falsch beschrieben hab. :lol: :lol: Danke im vorraus!

[Edit by L-ectron-X: Dem Beitrag einen ordentlichen Titel verpasst

 

[JPKI]

Bin jetzt zu faul um das durchzulesen, aber ich finde es unverschämt, so einen Thread-Titel bei so ner Menge Text zu verwenden, und dann noch nicht einmal Code-Tags zu verwenden :roll: .

 

[merlin2]

Ich kann mich meinem Vorredner nur anschließen - und dabei vergisst er, sich über den Titel selbst zu beschweren.
Dass sich die Leute nicht mal einen Betreff ausdenken können!

 

[HoaX]

er hat sich doch einen ausgedacht, nur eben keinen der annähernd passt

 

[L-ectron-X]

Ein Applet erbt von Panel. Du kannst also jedes Applet als Panel-Ersatz verwenden, sofern es in deinem Classpath liegt. Nur musst du die Applet-Methoden aus dem Lebenszyklus selbst aufrufen.

 

[MartinDeluxe]

Erstmal vielen dank an denjenigen der mir da geholfen hat.(Thema+Code) Dann wollt ich mich auch gleich mal Entschuldigen! Sry! Aha und dh? Wie sähe das zum Beispiel aus?

Danke für die Antworten!

 

[L-ectron-X]

Ich kenne den Code von deinem Applet nicht, welches du in einem anderen Applet anzeigen willst.
Im Prinzip erzeugst du eine Instanz deines Applets, rufst die init()-Methode und dann die start()-Methode deines Applets auf und fügst es als Komponente dem Applet hinzu, welches es anzeigen soll.

 

[MartinDeluxe]

Ok danke, hat mir sehr geholfen!!

Das ist mein Programm das in den Appelt laufen soll.

Guck mal, was ganz einfaches:

import java.awt.*;
import javax.swing.*;

public class EmbededApplet extends JApplet {
   private Switch s;
   
   public void init() {
      getContentPane().setBackground(Color.RED);
   }
   
   public void start() {
      if(s == null) {
         s = new Switch();
         s.start();
      }
   }
   
   public void stop() {
      s.interrupt();
      s = null;
   }
   
   class Switch extends Thread {
      public void run() {
         while(!isInterrupted()) {
            try {
               Thread.sleep(500);
            }
            catch(InterruptedException e) {
               interrupt();
            }

            if(getContentPane().getBackground() == Color.RED) {
               getContentPane().setBackground(Color.GREEN);
            }
            else {
               getContentPane().setBackground(Color.RED);
            }
         }
      }

   }
}

import java.awt.*;
import javax.swing.*;

public class AppletInAppletDemo extends JApplet {
   private EmbededApplet emAp;
   
   public void init() {
      setLayout(new GridLayout(0, 1));
      emAp = new EmbededApplet();
      emAp.init();
      emAp.start();
      getContentPane().add(emAp);
      
      JPanel p = new JPanel();
      p.setBackground(Color.YELLOW);
      getContentPane().add(p);
   }

   public void stop() {
      emAp.stop();
   }
}

Kompiliere das mal, lege AppletInAppletDemo in eine HTML-Datei und probiere es mal aus.
