Chris,
I really like this idea.
I hacked Touchy a while back but then decided to go in a different
direction for a past project but I have a lot of interest in this for
future "customized" non traditional EMC2 applications.
I'd really like to try this out.. Can you push it to a new branch on
the Git server?
Thanks!

Hi guys.
been working on gladevcp.
much like pyvcp it uses the same syntaxts to load from HAL:
loadusr gladevcp -g 500x500 200+200 -c componentname gladefile.glade
it can make standalone panels or be incorporated in a gtk program
You build and configure the HAL widgets along side regular widgets
using the glade UI editor. they can be saved as libglade (best) or
gtkbuilder (coming along) projects.. Then call gladevcp and it will parse
and export HAL pins for any special 'HAL isized' widgets it finds.
right now there are a few regular widgets with HAL pins
(buttons and spin boxes etc) a couple that export pins for sensitivity
and one custom widget - an led in round, square, or oval.
see here: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?GladeVcp
So in my eyes gladevcp is gonna be a useful addition to emc.
In the not too far future I I would like to add it to master
but I have some questions first.
on the glade side there is a catalog file that adds the widgets to
glade UI
It is usually installed in usr/share/glade3/catalogs
I can link to a different folder for a run-n-place .
What folder in EMC should i put it?
there are three python files to add custom widgets .
Glade uses them and so will any program that uses those widgets.
In glade they usually go in usr/lib/glade3/modules
again I can link to them
judging by pyvcp maybe they should go in emc2's lib/python?
gladevcp itsself is two files. a general parser / HAL pin maker and a
standalone panel builder. very much like pyvcp
again judging by pyvcp they should go in lib/python
Now to make gladevcp really useful , with Chris R's permission
I would like to add about twenty line of code to touchy and touchy's
hal_interface.
and export an environment variable INI_DIR from scripts/emc
this would allow touchy to check to see if there is a local copy of
toughy.glade in
the loading configs folder (INI_DIR) and call gladevcp_makepins to
parse and make
any found HAL widgets. If the touchy.glade file is not modified then
touchy does not
make any extra pins or look/act any different.
I've done most of what I have talked about here, in a local (and
dirty) copy of mine
(other then having the MAKE file make links to glade) and it works great.
I'll stop talking at this point to see if anyone sees some potential
problems with
what i am asking.
Thanks Chris M
