Declare MetaType object



  • I trying to create a custom object, but when add a Q_DECLARE_METATYPE, I have a compile error like this:
    /opt/QtSDK/Desktop/Qt/4.8.1/gcc/include/QtCore/qmetatype.h:141: error: call of overloaded 'PluginInfo()' is ambiguous

    Is posible use QMetatype with custom QObject?.

    Here after you can see my header file:

    @#ifndef PLUGININFO_H
    #define PLUGININFO_H

    #include <QObject>
    #include <QMetaType>
    #include <QDebug>
    #include <QtGui>

    class PluginInfo : public QObject
    {
    Q_OBJECT

    Q_PROPERTY(QString id READ id WRITE setId RESET resetId)
    Q_PROPERTY(QString fileName READ fileName WRITE setFileName RESET resetFileName)
    Q_PROPERTY(QString name READ name WRITE setName RESET resetName)
    Q_PROPERTY(QString version READ version WRITE setVersion RESET resetVersion)
    Q_PROPERTY(QString summary READ summary WRITE setSummary RESET resetSummary)
    Q_PROPERTY(QString category READ category WRITE setCategory RESET resetCategory)
    Q_PROPERTY(QString applyTo READ applyTo WRITE setApplyTo RESET resetApplyTo)
    Q_PROPERTY(QString author READ author WRITE setAuthor RESET resetAuthor)
    Q_PROPERTY(QString mail READ mail WRITE setMail RESET resetMail)
    Q_PROPERTY(QString webside READ webside WRITE setWebside RESET resetWebside)
    Q_PROPERTY(QString licence READ licence WRITE setLicence RESET resetLicence)
    Q_PROPERTY(QIcon icon READ icon WRITE setIcon RESET resetIcon)
    Q_PROPERTY(bool configurable READ isConfigurable WRITE setConfigurable RESET resetConfigurable)
    Q_PROPERTY(QStringList configList READ configList WRITE setConfigList RESET resetConfigList)
    

    public:
    PluginInfo();
    PluginInfo(const PluginInfo &);
    ~PluginInfo();

    PluginInfo(QObject *parent = 0);
    
    QString id() const;
    QString fileName() const;

    private:
    QString m_id;
    QString m_fileName;
    QString m_name;
    QString m_version;
    QString m_summary;
    QString m_category;
    QString m_applyTo;

    QString m_mail;
    QString m_webside;

    public slots:
    void setId(const QString &);
    void setFileName(const QString &);
    void setName(const QString &);
    void setVersion(const QString &);
    void setSummary(const QString &);

    void setApplyTo(const QString &);

    void setMail(const QString &);

    void setConfigurable(const bool);
    void setConfigList(const QStringList &);

    void resetAll();

    void resetWebside();
    void resetLicence();
    void resetIcon();

    public:
    PluginInfo& operator =(const PluginInfo &);
    bool operator ==(const PluginInfo &) const;
    friend QDataStream& operator <<(QDataStream &, const PluginInfo &);
    friend QTextStream& operator <<(QTextStream &, const PluginInfo &);

    };

    Q_DECLARE_METATYPE(PluginInfo)

    #endif // PLUGININFO_H

    Yeap, ‘PluginInfo()’ is ambiguous. See lines 29 and 33.



  • Oh!!! Tobias,

    Thank you, yes I was a fool. QObject parent = 0 is default constructor.

    Best regards,
