On X11, this maps trivially to the Xdnd protocol. On + Mac, although some applications use MIME to describe clipboard + contents, it is more common to use Apple's UTI format. + + QMacPasteboardMime's role is to bridge the gap between MIME and UTI; + By subclasses this class, one can extend Qt's drag and drop + and clipboard handling to convert to and from unsupported, or proprietary, UTI formats. + + A subclass of QMacPasteboardMime will automatically be registered, and active, upon instantiation. + + Qt has predefined support for the following UTIs: + \list + \i public.utf8-plain-text - converts to "text/plain" + \i public.utf16-plain-text - converts to "text/plain" + \i public.html - converts to "text/html" + \i public.url - converts to "text/uri-list" + \i public.file-url - converts to "text/uri-list" + \i public.tiff - converts to "application/x-qt-image" + \i public.vcard - converts to "text/plain" + \i com.apple.traditional-mac-plain-text - converts to "text/plain" + \i com.apple.pict - converts to "application/x-qt-image" + \endlist + + When working with MIME data, Qt will interate through all instances of QMacPasteboardMime to + find an instance that can convert to, or from, a specific MIME type. It will do this by calling + canConvert() on each instance, starting with (and choosing) the last created instance first. + The actual conversions will be done by using convertToMime() and convertFromMime(). + + \note The API uses the term "flavor" in some cases. This is for backwards + compatibility reasons, and should now be understood as UTIs. +*/ + +/*! \enum QMacPasteboardMime::QMacPasteboardMimeType + \internal +*/ + +/*! + Constructs a new conversion object of type \a t, adding it to the + globally accessed list of available convertors. +*/ +QMacPasteboardMime::QMacPasteboardMime(char t) : type(t) +{ + globalMimeList()->append(this);
