Wrapping Texture on CuboidMesh

[Zee_07]

Currently if i am applying texture on CuboidMesh it displays same texture image on each side of cuboid rather than wrapping the whole cuboid.
For example I want to make a dice but with fallowing code it display all the dots of dice (whole texture image) on each side. Fallowing is my code snippet:

Qt3DExtras::QCuboidMesh *cuboid = new Qt3DExtras::QCuboidMesh();
   cuboid->setXExtent(2);
    cuboid->setYExtent(2);
    cuboid->setZExtent(2);
 Qt3DExtras::QTextureMaterial   *cuboidMaterial = new Qt3DExtras::QTextureMaterial  ();

    Qt3DRender::QTexture3D  *texture2d = new Qt3DRender::QTexture2D ();
    texture2d->setWidth(20);
    texture2d->setHeight(20);
    texture2d->setFormat(Qt3DRender::QAbstractTexture::TextureFormat::RGB8_UNorm);
    texture2d->setGenerateMipMaps(true);
    texture2d->setMagnificationFilter(Qt3DRender::QAbstractTexture::Filter::Linear);
    texture2d->setMinificationFilter(Qt3DRender::QAbstractTexture::Filter::LinearMipMapLinear);
    texture2d->setWrapMode(Qt3DRender::QTextureWrapMode(Qt3DRender::QTextureWrapMode::ClampToEdge));

    Qt3DRender::QTextureImage *diffuseImage = new Qt3DRender::QTextureImage();
    diffuseImage->setSource(QUrl::fromLocalFile("ex.png"));

    texture2d->addTextureImage(diffuseImage);

    cuboidMaterial->setTexture(texture2d);
