On Windows the default choice is Direct 3D, therefore the removal of ANGLE is alleviated by having support for graphics APIs other than OpenGL as well. + + \section2 Native clipboard integration + + Qt 5 provided interfaces for integrating platform specific or custom + clipboard formats into Qt through \c QMacPasteboardMime in \c QtMacExtras, + and \c QWindowsMime from the Windows QPA API. Since Qt 6.6, the + equivalent functionality is provided by the classes QUtiMimeConverter for + \macos, and the QWindowsMimeConverter for Windows. + + Porting from QWindowsMime to QWindowsMimeConverter requires practically no + changes, as the virtual interface is identical. However, in Qt 6 it is no + longer needed to register a QWindowsMimeConverter implementation; + instantiating the type implicitly registers the converter. + + Porting a QMacPasteboardMime to QUtiMimeConverter requires renaming some of + the virtual functions. Note that the \c{QMacPasteboardMime} API used the + outdated term \c{flavor} for the native clipboard format on \macos, whereas + the platform now uses \c{Uniform Type Identifiers}, i.e. \c{UTI}s, which Qt + has adapted for function and parameter names. + + The \c{mimeFor} and \c{flavorFor} functions are replaced by the + \l{QUtiMimeConverter::}{mimeForUti} and \l{QUtiMimeConverter::}{utiForMime} + implementations, respectively. Those should return the name of the mime + type or \c{UTI} that the converter can convert the input format to, so a + port usually just involves renaming existing overrides. The + \c{convertToMime}, \c{convertFromMime}, and \c{count} functions in + QUtiMimeConverter are identical to their QMacPasteboardMime versions. + + The \c{canConvert}, \c{converterName} functions are no longer needed, they + are implied by implementation of the above functions, so overrides of those + functions can be removed. + + As with the the QWindowsMimeConverter, registration is done by instantiating + the type. */ |
