Qt使用phonon单曲循环

从国外网站找来的。测试后可以使用。

#ifndef MAIN_H
#define MAIN_H

#include <QMainWindow>
#include <phonon/MediaObject>
#include <phonon/VideoWidget>
#include <phonon/AudioOutput>

class Player : public QMainWindow
{
    Q_OBJECT

public:
    Player(QWidget *parent = 0);

public slots:
    void play();

private slots:
    void finished();

private:
    Phonon::MediaObject *mediaObject;
};

#endif // MAIN_H

#include <QApplication>

#include "main.h"

Player::Player(QWidget *parent) : QMainWindow(parent)
{
    mediaObject = new Phonon::MediaObject(parent);
    Phonon::AudioOutput *audioOutput = new Phonon::AudioOutput(Phonon::MusicCategory, parent);
    Phonon::createPath(mediaObject, audioOutput);
