sorry @eXpl0it3r, My description was not enough!
I think my Opengl context is differ from sf::RenderTexture and I can not bind sf::Texture of RenderTexture to my mesh.

I maked a program for drawing mesh in video every frame in Qt by Opengl,  I binded texure and draw mesh correctly, but when I change texture (with SFML::Texture in above code), it didn't work.(I didn't use from sf::window and ...)

I want to draw my mesh by using  texture of SFML without using from (sf::window ,sf::Renderwindow....)

    sf::RenderTexture renderTexture;
    renderTexture.create(800,600);
    renderTexture.clear(sf::Color::Blue);

    sf::Text text;
    // select the font
    sf::Font font;
    if (!font.loadFromFile("BNazanin.ttf"))
    {
        // error...
    }
    text.setFont(font); // font is a sf::Font
    // set the string to display
    text.setString("hello");
    // set the character size
    text.setCharacterSize(40); // in pixels, not points!
    // set the color
    text.setColor(sf::Color::Red);
    // set the text style
    text.setStyle(sf::Text::Bold | sf::Text::Underlined);

    renderTexture.draw(text); // or any other drawable
    renderTexture.display();

    //renderTexture.getTexture().copyToImage().saveToFile("test.png");
    const sf::Texture& texture = renderTexture.getTexture()

   sf::Texture::bind(&texture);

  _shaderProgram->bind();
  _shaderProgram->setUniformValue("modelInWorldMatrix", _model2WorldMatrix);
  glFlush();
  QOpenGLContext::currentContext()->functions()->glDrawArrays(_mode, startVertex, std::min(vertexCount, verticesCount()));;

it save texture correctly, but when i use binded texture for drawing my mesh in Qt Scene, it Doesn't work!
