Problem with phonon in another class

Hello. I want to do a litte music player based on phonon libs.

I want to make another class with operations like play, stop etc.

Code:

---

#include "plik.h"
 
#include <QString>
#include <QDebug>
 
#include <phonon/Global>
#include <phonon/MediaObject>
#include <phonon/AudioOutput>
#include <phonon/MediaSource>
#include <phonon/Path>
 
 
Phonon::MediaObject *mediaObject;
Phonon::AudioOutput *audioOutput;
 
 
Plik::Plik()
{
    this->next = NULL;
    this->prev = NULL;
}
 
void Plik::setPath(QString path)
{
    this->path = path;
    return;
}
 
QString Plik::returnPath()
{
    return this->path;
}
 
void Plik::playFile()
{
    mediaObject = new Phonon::MediaObject(this);
    audioOutput = new Phonon::AudioOutput(Phonon::MusicCategory,this);
 
    mediaObject->setCurrentSource(Phonon::MediaSource("/home/matulik/test.mp3"));
    audioOutput = new Phonon::AudioOutput(Phonon::MusicCategory,this);
    Phonon::Path path = Phonon::createPath(mediaObject,audioOutput);
 
    mediaObject->setTickInterval(1000);
    audioOutput->setVolume(100);
    audioOutput->setMuted(FALSE);
    mediaObject->play();
 
}

---

And in mainwindow:

Code:

---

Plik p1;
    p1.playFile();

---

And this doesnt work.

I dont know where is the problem, becouse the same source code coping to mainwindow works..

Code:

---

#include "odplayer.h"
#include "ui_odplayer.h"
#include "plik.h"
 
#include <QString>
#include <QDebug>
 
#include <phonon/Global>
#include <phonon/MediaObject>
#include <phonon/AudioOutput>
#include <phonon/MediaSource>
#include <phonon/Path>
 
 
Phonon::MediaObject *mediaObject;
Phonon::AudioOutput *audioOutput;
 
 
odplayer::odplayer(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::odplayer)
{
    ui->setupUi(this);
 
    mediaObject = new Phonon::MediaObject(this);
    audioOutput = new Phonon::AudioOutput(Phonon::MusicCategory,this);
 
    mediaObject->setCurrentSource(Phonon::MediaSource("/home/matulik/test.mp3"));
    audioOutput = new Phonon::AudioOutput(Phonon::MusicCategory,this);
    Phonon::Path path = Phonon::createPath(mediaObject,audioOutput);
 
    mediaObject->setTickInterval(1000);
    audioOutput->setVolume(100);
    audioOutput->setMuted(FALSE);
    mediaObject->play();
}
 
odplayer::~odplayer()
{
    delete ui;
}

---

Someone can help?

In this code, what is wrong?

Code:

---

void func()
{
  Plik p1;
  p1.playFile();
}

---

fyi:
posting code like this

Code:

---

Plik p1;
  p1.playFile();

---

is not helpful at all because there is no context, e.g. class + method name

Its like this:

Code:

---

#include "odplayer.h"
#include "ui_odplayer.h"
#include "plik.h"
 
#include <QString>
#include <QDebug>
 
#include <phonon/Global>
#include <phonon/MediaObject>
#include <phonon/AudioOutput>
#include <phonon/MediaSource>
#include <phonon/Path>
 
 
Phonon::MediaObject *mediaObject;
Phonon::AudioOutput *audioOutput;
 
 
odplayer::odplayer(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::odplayer)
{
    ui->setupUi(this);
    Plik p1;
    p1.playFile();
}
 
odplayer::~odplayer()
{
    delete ui;
}

---

yeah, now tell me what is wrong with this

Code:

---

odplayer::odplayer(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::odplayer)
{
    ui->setupUi(this);
    Plik p1;
    p1.playFile();
}

---

Hint: It's a c++ 'thing'.

Ok, I know where is problem:

Code:

---

File* f1 = new File;
    f1->setPath("/home/matulik/test.mp3");
    qDebug()<<f1->returnPath();
    f1->playFile();

---

Thanks very much for hint :)

what's a `File`? I haven't seen that in your previous code. And what did I just say about posting code with no context?

By the way, you now have a memory leak.
