\class QUtiMimeConverter
\brief The QUtiMimeConverter class converts between a MIME type and a
{Uniform Type Identifier (UTI)} format.
\since 6.5
\ingroup draganddrop
\inmodule QtGui
Qt's drag and drop and clipboard facilities use the MIME
standard. 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.
QUtiMimeConverter'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.
Construct an instance of your converter implementation after instantiating
QGuiApplication:
\code
int main(int argc, char **argv)
{
QGuiApplication app(argc, argv);
JsonMimeConverter jsonConverter;
}
\endcode
Destroying the instance will unregister the converter and remove support
for the conversion. It is also valid to heap-allocate the converter
instance; Qt takes ownership and will delete the converter object during
QGuiApplication shut-down.
Qt has predefined support for the following UTIs:
\list
\li public.utf8-plain-text - converts to "text/plain"
\li public.utf16-plain-text - converts to "text/plain"
\li public.text - converts to "text/plain"
\li public.html - converts to "text/html"
\li public.url - converts to "text/uri-list"
\li public.file-url - converts to "text/uri-list"
\li public.tiff - converts to "application/x-qt-image"
\li public.vcard - converts to "text/plain"
\li com.apple.traditional-mac-plain-text - converts to "text/plain"
\li com.apple.pict - converts to "application/x-qt-image"
\endlist
When working with MIME data, Qt will iterate through all instances of QUtiMimeConverter to find
find an instance that can convert to, or from, a specific MIME type. It will do this by calling
mimeForUti() or utiForMime() on each instance, starting with (and choosing) the last created
instance first. The actual conversions will be done by using convertToMime() and convertFromMime().
