Functions

canConvert()

bool QMacPasteboardMimeTiff::canConvert ( const QString &  mime, QString  flav  )

virtual

Returns true if the convertor can convert (both ways) between mime and flav; otherwise returns false.

All subclasses must reimplement this pure virtual function.

Implements QMacPasteboardMime.

Definition at line 681 of file qmime_mac.cpp.

{
    return flav == QLatin1String("public.tiff") && mime == QLatin1String("application/x-qt-image");
}

convertFromMime()

QList< QByteArray > QMacPasteboardMimeTiff::convertFromMime ( const QString &  mime, QVariant  data, QString  flav  )

virtual

Returns data converted from MIME type mime to Mac UTI flav.

Note that Mac flavors must all be self-terminating. The return value may contain trailing data.
