+ \class QWindowsMime + \brief The QWindowsMime class maps open-standard MIME to Window Clipboard formats. + \ingroup draganddrop + + Qt's drag-and-drop and clipboard facilities use the MIME standard. + On X11, this maps trivially to the Xdnd protocol, but on Windows + although some applications use MIME types to describe clipboard + formats, others use arbitrary non-standardized naming conventions, + or unnamed built-in formats of Windows. + + By instantiating subclasses of QWindowsMime that provide conversions + between Windows Clipboard and MIME formats, you can convert + proprietary clipboard formats to MIME formats. + + Qt has predefined support for the following Windows Clipboard formats: + + \table + \header \o Windows Format \o Equivalent MIME type + \row \o \c CF_UNICODETEXT \o \c text/plain + \row \o \c CF_TEXT \o \c text/plain + \row \o \c CF_DIB \o \c{image/xyz}, where \c xyz is + a \l{QImageWriter::supportedImageFormats()}{Qt image format} + \row \o \c CF_HDROP \o \c text/uri-list + \row \o \c CF_INETURL \o \c text/uri-list + \row \o \c CF_HTML \o \c text/html + \endtable + + An example use of this class would be to map the Windows Metafile + clipboard format (\c CF_METAFILEPICT) to and from the MIME type + \c{image/x-wmf}. 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(). +*/ + +/*! +Constructs a new conversion object, adding it to the globally accessed +list of available converters. +*/ +QWindowsMime::QWindowsMime() +{ + theMimeList()->addWindowsMime(this);
