头文件要加

头文件不能写成

QT +=phonon(害我找了一晚上的错)

应该写成这样

QT\+= phonon

mainwindow.h

\#ifndef MAINWINDOW\_H

#define MAINWINDOW_H

#include <QMainWindow>

#include <Phonon>

namespace Ui {

class MainWindow;

}

class MainWindow : public QMainWindow

{

Q_OBJECT

public:

explicit MainWindow(QWidget *parent = 0);

~MainWindow();

private slots:

void on_play_clicked();

void finished();

void getbool();

private:

Ui::MainWindow *ui;

Phonon::AudioOutput *audioOutput;

};

#endif // MAINWINDOW_H
