Hi, Im trying to make a media player in Eclipse.
Its just a simple thing not an advanced one but i cant get it to work.
I have looked at some examples and tried to create a simular version.
I could really use some hints on how to make it play the files.
this is the code: (the problems are specified in the bottom of the thread)
MediaPlayer.java:
import java.awt.BorderLayout;
import java.awt.Component;
import java.awt.Container;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.beans.EventHandler;
import java.io.File;
import javax.sound.midi.ControllerEventListener;
import javax.swing.JButton;
import javax.swing.JFileChooser;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
public class MediaPlayer extends JFrame {
private Player player;
private File file;
public MediaPlayer(){
super ("demo");
JButton openFile = new JButton("open file to play");
openFile.addActionListener(
new ActionListener() {
public void actionPerformed (ActionEvent e )
{
openFile();
createPlayer();
}
}
);
getContentPane().add(openFile,BorderLayout.NORTH);
setSize(300,300);
show();
}
private void openFile(){
JFileChooser fileChooser=new JFileChooser();
fileChooser.setFileSelectionMode(
JFileChooser.FILES_ONLY);
int result=fileChooser.showOpenDialog(this);
if (result==JFileChooser.CANCEL_OPTION)
file=null;
else file=fileChooser.getSelectedFile();}
private void createPlayer(){
if (file==null) return;
removePreviousPlayer();
try{
player=Manager.createRealizedPlayer(file.toURL());
player.addControllerListener (new EventHandler());
player.start();
}
catch (Exception e){JOptionPane.showMessageDialog( this,
"Invalid file or location", "Error loading file",
JOptionPane.ERROR_MESSAGE);}
}
private void removePreviousPlayer()
{
if (player==null)
return;
player.close();
Component visual = player.getVisualComponent();
Component control = player.getControlPanelComponent();
Container c=getContentPane();
if(visual !=null)
c.remove(control);
if (control !=null)
c.remove(control);
}
private class EventHandler implements ControllerListener {
public void controllerUpdate (ControllerEvent e){
if (e instanceof RealizeCompleteEvent){
Container c=getContentPane();
Component visualComponent= player.getVisualComponent();
if (visualComponent !=null)
c.add(visualComponent, BorderLayout.CENTER);
Component controlsComponent=player.getControlPanelComponent();
if (controlsComponent !=null)
c.add(controlsComponent, BorderLayout.SOUTH);
c.doLayout();
}
}}
}
Player.java
import java.awt.Component;
import MediaPlayer.EventHandler;
public class Player {
/**
* @param args
*/
public static void main(String[] args) {
}
public void addControllerListener() {
}
public void start() {
if (this != null)
this.start();
}
public void close() {
this.close();
}
public Component getVisualComponent() {
return null;
}
public Component getControlPanelComponent() {
return null;
}
}
and the program: MPlayer.java
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
public class MPlayer {
/**
* @param args
*/
public static void main(String[] args) {
MediaPlayer mp=new MediaPlayer();
mp.addWindowListener(
new WindowAdapter(){
public void windowClosing(WindowEvent e)
{System.exit(0);}
});
}
}
The player opens and you can choose files but i cant get it to play them.
As you see i am yet to specify the methods in Player.java.
Manager also cannot be resolved to a type, where do i create this?
and what do i do with it.
Any hints on what i have to do to make it work?
'Couse im really really outa my leauge here :P
The private class EventHandler also has some flaws if i may call it so :P
The Controller Listener , (ControllerEvent e) and RealizeCompleteEvent cannot be resolved to a type.
I would REALLY really appreciate some help on this one.
