Problems with QObject

[janorcutt]

hey peeps, just a quick one. Here is the header for a class i'm writing but when i compile i get:

error: ‘QObject& QObject::operator=(const QObject&)’ is private within this context

error: ‘QObject& QObject::operator=(const QObject&)’ is private within this context

and it points to the line containing the opening brace of the class.... any thoughts would be appreciated thanx.

#include <QObject>
#include <QVariant>
#include <QString>
 
class mediaItem : public QObject
{
Q_OBJECT
public:
    explicit mediaItem(QObject *parent = 0);
    mediaItem(const mediaItem&);
 
    enum FileType { OGG , FLAC , MP3 , M4A , WAV };
    QString filename() { return m_filename; }
    QString title() { return m_title; }
    QString artist() { return m_artist; }
    QString album() { return m_album; }
    QVariant duration() { return m_duration; }
    QVariant bpm() { return m_bpm; }
    QVariant bitrate() { return m_bitrate; }
    QVariant tracknum() { return m_tracknum; }
    QVariant discnum() { return m_discnum; }
    int filetype() { return m_filetype; }

[squidge]

any particular reason you are inheriting QObject?

[janorcutt]

seemed like a good idea at the time

I am not sure but it could be because of the "explicit" in front of your c-tor. Try to compile without it. If all works you probably have a line like

mediaItem item;
item = /* any other QObject */

mediaItem item;
item = /* any other QObject */
