129 \class QMacPasteboardMime
130 \brief The QMacPasteboardMime class maps open-standard MIME to Mac flavors.
131 \since 4.2
132 \ingroup io
133 \ingroup draganddrop
134 \ingroup misc
135
136 Qt's drag and drop support and clipboard facilities use the MIME
137 standard. On X11, this maps trivially to the Xdnd protocol, but on
138 Mac although some applications use MIME types to describe clipboard
139 formats, others use arbitrary non-standardized naming conventions,
140 or unnamed built-in Mac formats.
141
142 By instantiating subclasses of QMacPasteboardMime that provide conversions
143 between Mac flavors and MIME formats, you can convert proprietary
144 clipboard formats to MIME formats.
145
146 Qt has predefined support for the following Mac flavors:
147 \list
148 \i kScrapFlavorTypeUnicode - converted to "text/plain;charset=ISO-10646-UCS-2"
149 \i kScrapFlavorTypeText - converted to "text/plain;charset=system" or "text/plain"
150 \i kScrapFlavorTypePicture - converted to "application/x-qt-image"
151 \i typeFileURL - converted to "text/uri-list"
152 \endlist
153
154 You can check if a MIME type is convertible using canConvert() and
155 can perform conversions with convertToMime() and convertFromMime().
