- \class QWindowsMime - \brief The QWindowsMime class maps open-standard MIME to Window Clipboard formats. - \ingroup draganddrop - \inmodule QtWidgets - - 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);
