QML and SFML

[Eray]

Hello,

I am trying to create a QML component that displays a rendering of SFML.

The problem being that the SFML generates textures in its own context, I would like to recover its textures in my context to create a QSGTexture.

I managed to create a context and share it with my qt context normally!
But the creation of the texture does not work, createTextureFromNativeObject simply returns me a black texture

Here is my code, no "assert" ... no particular problem, my image which records my rendering is also good

            QOpenGLContext *current = m_window->openglContext();
            assert(current);

            sf::Context contextSFML;

            QSurfaceFormat surfaceFormat;
            surfaceFormat.setRenderableType(QSurfaceFormat::OpenGL);
            surfaceFormat.setProfile(QSurfaceFormat::CompatibilityProfile);

            assert(m_render.create(800, 600) == true);
            m_render.setActive(true);

            m_shape.setFillColor(sf::Color(150, 50, 250));
            m_shape.setSize({20.f, 20.f});
            m_shape.setPosition({20.f, 20.f});

            GLXContext currentContext;
            currentContext = glXGetCurrentContext();
            assert(currentContext);

            QOpenGLContext *context = new QOpenGLContext();
            context->setFormat(surfaceFormat);
            context->setNativeHandle(QVariant::fromValue(QGLXNativeContext(currentContext)));
            context->setShareContext(current);
            context->create();
            assert(context->isValid());

            assert(QOpenGLContext::areSharing(current, context));
            assert(QOpenGLContext::areSharing(context, current));

            m_texture.create(800, 600);
            m_shape.setPosition({m_x, 20.f});
            m_render.clear(sf::Color::Green);
            m_render.draw(m_shape);
            m_render.display();

            sf::Texture tmpTexture(m_render.getTexture());
            sf::Image img = tmpTexture.copyToImage();
            m_texture.update(tmpTexture);
            img.saveToFile("~/tt.png");

            m_frame = QImage(img.getPixelsPtr(), 800, 600, QImage::Format_ARGB32);

            assert(tmpTexture.getNativeHandle() != 0);

            qDebug() << "ID : " << tmpTexture.getNativeHandle() << " Size texture " << tmpTexture.getSize().x << " " << tmpTexture.getSize().y;

            GLuint texture = static_cast<GLuint>(tmpTexture.getNativeHandle());
            assert(texture);

            m_textureQt =  m_window->createTextureFromNativeObject(QQuickWindow::NativeObjectTexture, &texture, 0, QSize(800, 600));
            assert(m_textureQt);
