I had someone mention this a while ago. I tried to find it to understand
what was being mentioned, but either was looking for the wrong thing, or
didn't understand what was being said. I'll try to look into it some more.
The only reason I mentioned Qt is I already on the learning curve on it.
It's an old saying I once learned. To a person who's only tool is a hammer,
every problem has a nail head.

James, you might have noticed a recent development called pyVCP:
http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?PyVCP
I assume your encoder counts or machine position are now HAL_FLOAT
signals? If you want a HAL_FLOAT displayed on-screen without running emc
you don't have to reinvent the wheel with QT3, you can do it very easily
and quickly with pyvcp.
currently pyvcp runs when AXIS is run, but the modifications to make it
run standalone with a use-specified input file are small. I (or someone
else) just have to modify the parser to take an optional input argument,
and create a root window when AXIS does not do that.
