Exporting wx gui widgets over the internet

I am having trouble getting wx windows to appear. The machine running
the code v3.4.0 is at the far end of a fast 1GB/s link so the display is
on another host 40 miles away.

I can’t seem to get any wx gui windows more complex than a simple text
box to appear, nx, exceed both the same. It works locally but I don’t
want an 80 mile round trip each time I want to look at something. I
assume I need to tell gnuradio to export the display but how?
