 Viewport, this is effectively a screen capture. This is done with the
 following code:

 But if you use this in ``_ready()`` or from the first frame of the :ref:`Viewport's <class_Viewport>` initialization,
 you will get an empty texture because there is nothing to get as texture. You can deal with
 it using (for example):
 
-::
+.. tabs::
+ .. code-tab:: gdscript GDScript
 
  # Wait until the frame has finished before getting the texture.
  await RenderingServer.frame_post_draw
  # You can get the image after this.
