no
from jtgui import emc_interface
means from folder jtgui import emc_interface
is your folder called that?
hold on for sample code for a widget...

I've gotten past that error but I think an internationalization thing is holding me up now with the gettext thing.
Ok, I'm past that and figured out where set_text was and now the libs load...

I understand some of the code but this I don't have a clue what it is doing. I do understand the class HAL_DRO but not what the (gtk.VBox) is for. I know that __gproperties__ is assigned a dictionary but not what __gproperties__ or __gtype_name__ does.
And some googling later I see that __gtype_name__ has something to do with creating a custom widget for Glade3.
And even more googling I see that __gproperties__ is used to create custom properties for a class.
Thanks
John
class HAL_DRO(gtk.VBox):
__gtype_name__ = 'HAL_DRO'
__gproperties__ = {
'is_editable' : ( gobject.TYPE_BOOLEAN, 'Is Editable', 'Ability to use a keyboard to enter data',
False, gobject.PARAM_READWRITE | gobject.PARAM_CONSTRUCT),
'font' : ( gobject.TYPE_STRING, 'Pango Font', 'Display font to use',
"sans 12", gobject.PARAM_READWRITE|gobject.PARAM_CONSTRUCT),
}
__gproperties = __gproperties__And some googling later I see that __gtype_name__ has something to do with creating a custom widget for Glade3.

WEEEE! I make a huge breakthrough!
I added to my __init__
self.emc = linuxcnc
self.status = self.emc.stat()
and a button
def on_test_button_clicked(self, widget, data=None):
self.status.poll()
print self.status.g5x_offset[0]
and too my surprise when I click on the button I get something... where does emc.stat come from so I can see what all is there?
Thanks

Yaaaay!!
yes the other stuff was boiler code for making a widget.
The emc.stat stuff was what I was wanting to show you.
info for emc.stat() which comes from module linuxcnc:
look through the example gscreen's emc_interface, emc_stats
self.emcstat is the same as your self.status.
also run an interactive python in a terminal (type python <enter>)
then:
import linuxcnc
then
help(linuxcnc)
gives a whole ton of info on the module
there is
stat()
error_channel()
command()
each has methods to call to do stuff.

If your interested in looking at the source for module linuxcnc
src/emc/usr_intf/axis/extentions/linuxcnc.cc
lot of python to c++ boiler code in there....
