Qt makes assumptions about its - parent-child hierarchy that make it complex to put an arbitrary Qt widget - into a hierarchy of "normal" views from Apple frameworks. QMacNativeWidget - bridges the gap between views and windows and makes it possible to put a - hierarchy of Qt widgets into a non-Qt window or view. - - QMacNativeWidget pretends it is a window (i.e. isWindow() will return true), - but it cannot be shown on its own. It needs to be put into a window - when it is created or later through a native call. - - Here is an example showing how to put a QPushButton into a NSWindow: - - \snippet qmacnativewidget/main.mm 0 - - Note that QMacNativeWidget requires knowledge of Cocoa. All it - does is get the Qt hierarchy into a window not owned by Qt. It is then up - to the programmer to ensure it is placed correctly in the window and - responds correctly to events. -*/ - -QT_BEGIN_NAMESPACE - -namespace { -// TODO use QtMacExtras copy of this function when available. -inline QPlatformNativeInterface::NativeResourceForIntegrationFunction resolvePlatformFunction(const QByteArray &functionName) -{ - QPlatformNativeInterface *nativeInterface = QGuiApplication::platformNativeInterface(); - QPlatformNativeInterface::NativeResourceForIntegrationFunction function = - nativeInterface->nativeResourceFunctionForIntegration(functionName); - if (Q_UNLIKELY(!function)) - qWarning("Qt could not resolve function %s from " - "QGuiApplication::platformNativeInterface()->nativeResourceFunctionForIntegration()", - functionName.constData()); - return function; -} -} //namespsace - -NSView *getEmbeddableView(QWindow *qtWindow) -{ - // Make sure the platform window is created - qtWindow->create(); - - // Inform the window that it's a subwindow of a non-Qt window.
