This conversion might simply be adding or removing - a header, or even just passing on the data. See \l{Drag and Drop} - for more information on choosing and definition MIME types. - - You can check if a MIME type is convertible using canConvertFromMime() and - can perform conversions with convertToMime() and convertFromMime(). - - \since 5.4 -*/ - -/*! - Constructs a new conversion object, adding it to the globally accessed - list of available converters. -*/ -QWinMime::QWinMime() -{ - if (!QMetaObject::invokeMethod(QGuiApplication::platformNativeInterface(), - "registerWindowsMime", Q_ARG(void *, this))) { - qWarning() << Q_FUNC_INFO << "Unable to register mime type."; - } -} - -/*! - Destroys a conversion object, removing it from the global - list of available converters. -*/ -QWinMime::~QWinMime() -{ - if (!QMetaObject::invokeMethod(QGuiApplication::platformNativeInterface(), - "unregisterWindowsMime", Q_ARG(void *, this))) { - qWarning() << Q_FUNC_INFO << "Unable to unregister mime type."; - } -} - -/*! - Registers the MIME type \a mime, and returns an ID number - identifying the format on Windows. -*/ -int QWinMime::registerMimeType(const QString &mime) -{ - int result = 0; - if (!QMetaObject::invokeMethod(QGuiApplication::platformNativeInterface(), - "registerMimeType", - Q_RETURN_ARG(int, result), - Q_ARG(QString, mime))) { - qWarning() << Q_FUNC_INFO << "Unable to register mime type " << mime; - } - return result; -} - -/*! - \fn bool QWinMime::canConvertFromMime(const FORMATETC &formatetc, const QMimeData *mimeData) const - - Returns true if the converter can convert from the \a mimeData to - the format specified in \a formatetc. - - All subclasses must reimplement this pure virtual function. -*/ - -/*! - \fn bool QWinMime::canConvertToMime(const QString &mimeType, IDataObject *pDataObj) const - - Returns true if the converter can convert to the \a mimeType from - the available formats in \a pDataObj. - - All subclasses must reimplement this pure virtual function. -*/ - -/*! - \fn QString QWinMime::mimeForFormat(const FORMATETC &formatetc) const - - Returns the mime type that will be created form the format specified - in \a formatetc, or an empty string if this converter does not support - \a formatetc. - - All subclasses must reimplement this pure virtual function. -*/ - -/*! - \fn QList<FORMATETC> QWinMime::formatsForMime(const QString &mimeType, const QMimeData *mimeData) const - - Returns a QList of FORMATETC structures representing the different windows clipboard - formats that can be provided for the \a mimeType from the \a mimeData. - - All subclasses must reimplement this pure virtual function. -*/ - -/*! - \fn QVariant QWinMime::convertToMime(const QString &mimeType, IDataObject *pDataObj, - QVariant::Type preferredType) const - - Returns a QVariant containing the converted data for \a mimeType from \a pDataObj. - If possible the QVariant should be of the \a preferredType to avoid needless conversions. - - All subclasses must reimplement this pure virtual function. -*/ - -/*! - \fn bool QWinMime::convertFromMime(const FORMATETC &formatetc, const QMimeData *mimeData, STGMEDIUM * pmedium) const - - Convert the \a mimeData to the format specified in \a formatetc. - The converted data should then be placed in \a pmedium structure. - - Return true if the conversion was successful. - - All subclasses must reimplement this pure virtual function. -*/ - -QT_END_NAMESPACE |
