Timer für Bildfolge in einem jLabel

[Durchstarter]

Hallo ich tüftle momentan an einen Programm, derzeit habe ich Oben Rechts ein jLabel (jLabel2) in dem ich gerne alle paar Sekunden ein anderes Bild einblenden möchte, allerdings weiß ich nicht so ganz wie ich das anstellen kann und im Internet fand ich auch keinen Lösungsansatz.

Ich vermute einen Start Button für den Timer erstellen zu müssen, aber das weiß ich nicht.

wie behebe ich das denn jetzt, ist bestimmt ganz simpel nur ich komme nicht drauf :lol:

Hallo Durchstarter,
ich empfehle eine Swing Timer mit Ihm ist es wesentlich einfacher ein Aktion Zeit gesteuert zu nutzen.

Beispiel:
TimerExample.java

import java.awt.Dimension;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.Timer;

/**
 *
 * @author Simon Schäfer <simon.schaefer@teamkoeln.com>
 */
public class TimerExample {
    private final JFrame frame;
    private final JButton btn;
    private final Timer timer;

    public TimerExample() {
        timer=new Timer(2000, new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                btn.setVisible(true);
            }
        });
        timer.setRepeats(false);
        
        frame=new JFrame("Timer Example");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        
        btn=new JButton("Start");
        btn.setPreferredSize(new Dimension(100,25));
        btn.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                btn.setVisible(false);
                timer.start();
            }
        });
        
        frame.add(btn);
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }
    
    public static void main(String[] args){
        new TimerExample();
    }

Mit der Methode timer.setReapeats(false) weist man den Timer an die Action nur einmal auszuführen und nicht alle 2 sec weider.

Gruß Simon

 

[Enceladus271]

In Zeile 127 möchtest du beim erzeugten TimerTask ja die run Methode überschreiben. Zwischen "new TimerTask()" und der geschweiften Klammer darf dann kein Semikolon stehen (der Teil in den geschweiften Klammern gehört ja mit zum TimerTask).

In Zeile 129 definiertst du eine Methode. Auch hier darf zwischen run() und der geschweiften Klammer kein Semikolon stehen.

Der ToggleButton3 soll jetzt die Abfolge der Bilder starten und bei x=0 anfangen
allerdings bleibt x immer 1 und steigt nicht an... hier der Code des Buttons (habe mir zur veranschaulichung das system.out.print eingefügt und beobachtet das x sich nicht verändert (Weil x bei jedem durchgang auf 0 gesetzt wird?! wie kann ich das geschickt umändern das es funktioniert mir fällt dazu nichts ein))

  public void jToggleButton3_ActionPerformed(ActionEvent evt) {
    Timer timer = new Timer();
    
    TimerTask task = new TimerTask()
    {
      public void run()
      {
        int x=0;

          Icon m=new ImageIcon("Ohne Titel_"+x+".png");
          jLabel2.setIcon(m);
          x++;
          System.out.print(x);

      }
    };  
    timer.scheduleAtFixedRate(task, 0, 1000);   
  } // end of jToggleButton3_ActionPerformed

wie schaffe ich es jetzt das x jede Sekunde um 1 ansteigt ? Ich dachte so wie ich das jetzt habe geht das, aber x wird ja bei jedem durchgang auf 0 gesetzt und das +1 genommen weshalb es immer 1 ist...

Würde mich über einen Lösungsvorschlag SEHR freuen

 

[Durchstarter]

Also da x immer auf 0 gesetzt wurde, habe ich eine neue private int z=0 erstellt und diese dann immer +1 genommen ( funktioniert so) nach 150 durchgängen bricht nun auch der Timer ab, (5 Sekunden a 30fps = 150 Bilder/Durchgänge) falls es jemanden Interessiert ist hier mein funktionierender Code (Fenstergrößen sind jetzt noch bisschen bearbeitet weil da noch was dazukommt )
