Display wire while OnlyRender is active?

Hey there,
is it somehow possibible to display the wireframe ob an object even if “Only Render” is toggled True in the Display Panel?
Can I somehow set it manually via python?

why is this a python-question?

you set the shading to wireframe and enable Render Only…

yeah… but I want the Textured model be visible underneath! And if I enable the wire in the object settings it is only viewable while Only Render is turned of.
So I thought maybe I can turn on the wireframe somehow with python!

i see, but python can’t do better than you can with mouse and keyboard. The show_wire property gets ignored when Only Render is enabled. You’d have to change the draw code and compile blender with that changes.
