It should compile with: \list \li Microsoft Visual Studio 2008 or later (using the Microsoft Windows SDK, (\c Q_CC_MSVC). \li Stock \l{http://mingw.org/}{MinGW} (\c Q_CC_MINGW). This version ships with headers that are missing a lot of WinAPI. \li MinGW distributions using GCC 4.7 or higher and a recent MinGW-w64 runtime API, such as \l{http://tdm-gcc.tdragon.net/}{TDM-GCC}, or \l{http://mingwbuilds.sourceforge.net/}{MinGW-builds} (\c Q_CC_MINGW and \c __MINGW64_VERSION_MAJOR indicating the version). MinGW-w64 provides more complete headers (compared to stock MinGW from mingw.org), including a considerable part of the Windows SDK. \li Visual Studio 2008 for Windows Embedded (\c Q_OS_WINCE). \endlist The file \c qtwindows_additional.h contains defines and declarations that are missing in MinGW. When encountering missing declarations, it should be added there so that \c #ifdefs for MinGW can be avoided. Similarly, \c qplatformfunctions_wince.h contains defines and declarations for Windows Embedded. When using a function from the WinAPI, the minimum supported Windows version and Windows Embedded support should be checked. If the function is not supported on Windows XP or is not present in the MinGW-headers, it should be dynamically resolved. For this purpose, QWindowsContext has static structs like QWindowsUser32DLL and QWindowsShell32DLL. All function pointers should go to these structs to avoid lookups in several places. \ingroup qt-lighthouse-win */ struct QWindowsIntegrationPrivate { #if defined(QT_OPENGL_ES_2) || defined(QT_OPENGL_DYNAMIC) typedef QSharedPointer QEGLStaticContextPtr; #endif #if !defined(QT_NO_OPENGL) && !defined(QT_OPENGL_ES_2) typedef QSharedPointer QOpenGLStaticContextPtr; #endif explicit QWindowsIntegrationPrivate(const QStringList ¶mList); ~QWindowsIntegrationPrivate(); unsigned m_options; QWindowsContext m_context; QPlatformFontDatabase *m_fontDatabase; #ifndef QT_NO_CLIPBOARD QWindowsClipboard m_clipboard; # ifndef QT_NO_DRAGANDDROP QWindowsDrag m_drag; # endif #endif #if defined(QT_OPENGL_ES_2) || defined(QT_OPENGL_DYNAMIC) QEGLStaticContextPtr m_staticEGLContext; #endif #if !defined(QT_NO_OPENGL) && !defined(QT_OPENGL_ES_2) QOpenGLStaticContextPtr m_staticOpenGLContext; #endif QScopedPointer m_inputContext; #ifndef QT_NO_ACCESSIBILITY QWindowsAccessibility m_accessibility; #endif QWindowsServices m_services; }; static inline unsigned parseOptions(const QStringList ¶mList, int *tabletAbsoluteRange, QtWindows::ProcessDpiAwareness *dpiAwareness) { unsigned options = 0; foreach (const QString ¶m, paramList) { if (param.startsWith(QLatin1String("fontengine="))) { if (param.endsWith(QLatin1String("freetype"))) { options |= QWindowsIntegration::FontDatabaseFreeType; } else if (param.endsWith(QLatin1String("native"))) { options |= QWindowsIntegration::FontDatabaseNative; } } else if (param.startsWith(QLatin1String("dialogs="))) { if (param.endsWith(QLatin1String("xp"))) { options |= QWindowsIntegration::XpNativeDialogs; } else if (param.endsWith(QLatin1String("none"))) { options |= QWindowsIntegration::NoNativeDialogs; } } else if (param == QLatin1String("gl=gdi")) { options |= QWindowsIntegration::DisableArb; } else if (param == QLatin1String("nomousefromtouch")) { options |= QWindowsIntegration::DontPassOsMouseEventsSynthesizedFromTouch; } else if (param.startsWith(QLatin1String("verbose="))) { QWindowsContext::verbose = param.right(param.size() - 8).toInt(); } else if (param.startsWith(QLatin1String("tabletabsoluterange="))) { *tabletAbsoluteRange = param.rightRef(param.size() - 20).toInt(); } else if (param.startsWith(QLatin1String("dpiawareness="))) { *dpiAwareness = static_cast(param.rightRef(param.size() - 13).toInt()); } } return options; } QWindowsIntegrationPrivate::QWindowsIntegrationPrivate(const QStringList ¶mList) : m_options(0) , m_fontDatabase(0) { int tabletAbsoluteRange = -1; // Default to per-monitor awareness to avoid being scaled when monitors with different DPI // are connected to Windows 8.1 QtWindows::ProcessDpiAwareness dpiAwareness = QtWindows::ProcessPerMonitorDpiAware; m_options = parseOptions(paramList, &tabletAbsoluteRange, &dpiAwareness); if (tabletAbsoluteRange >= 0) m_context.setTabletAbsoluteRange(tabletAbsoluteRange); m_context.setProcessDpiAwareness(dpiAwareness); } QWindowsIntegrationPrivate::~QWindowsIntegrationPrivate() { if (m_fontDatabase) delete m_fontDatabase; } QWindowsIntegration::QWindowsIntegration(const QStringList ¶mList) : d(new QWindowsIntegrationPrivate(paramList)) { #ifndef QT_NO_CLIPBOARD d->m_clipboard.registerViewer(); #endif d->m_context.screenManager().handleScreenChanges(); } QWindowsIntegration::~QWindowsIntegration() { } void QWindowsIntegration::initialize() { if (QPlatformInputContext *pluginContext = QPlatformInputContextFactory::create()) d->m_inputContext.reset(pluginContext); else d->m_inputContext.reset(new QWindowsInputContext); } bool QWindowsIntegration::hasCapability(QPlatformIntegration::Capability cap) const { switch (cap) { case ThreadedPixmaps: return true; #ifndef QT_NO_OPENGL case OpenGL: return true; case ThreadedOpenGL: #if defined(QT_OPENGL_ES_2) || defined(QT_OPENGL_DYNAMIC) return QOpenGLContext::openGLModuleType() != QOpenGLContext::DesktopGL ?
