Use the "image:" scheme for the URL source of the image, followed by the identifier \e wlshared, followed by the image file path. For example: \code Image { source: "image://wlshared/wallpapers/mybackground.jpg" } \endcode The shared texture module does not provide any directly usable QML types. */ QT_BEGIN_NAMESPACE class QWaylandTextureSharingPlugin : public QQmlExtensionPlugin { Q_OBJECT Q_PLUGIN_METADATA(IID QQmlExtensionInterface_iid) public: QWaylandTextureSharingPlugin(QObject *parent = nullptr) : QQmlExtensionPlugin(parent) {} void registerTypes(const char *uri) override { Q_ASSERT(uri == QStringLiteral("QtWayland.Client.TextureSharing")); qmlRegisterModule(uri, 1, 0); } void initializeEngine(QQmlEngine *engine, const char *uri) override { Q_UNUSED(uri); engine->addImageProvider("wlshared", new SharedTextureProvider); } }; QT_END_NAMESPACE #include "plugin.moc"
