I am also curious what you are doing as your 'jog' commands seem to actually just move the origin using g10?

That is right, It is just a easy (for the operator not for me) way for the operator to make simple incremental adjustments to the G54 machine coordinate system, rather than use the "touchoff system" This is much simpler for the way we use this machine. (It is for a gang router that is used for engraving multiple items.)

I've already made a similar pyvcp panel (and a huge pile of halui commands and subroutines) for another of our carving machines. This time I wanted to try glade which removed the need for halui and most of the subs, but the python part is kicking my butt.

That did the trick for me. (other than a couple of typos).

Now on to the next battle, I want to make the large ZW change depending on the state of a hal pin.
If false I'd like it to be black and ZW, if true blue and ZZ.

class HandlerClass:
    def __init__(self, halcomp,builder,useropts):
        self.builder = builder
        self.jog_increment = self.builder.get_object('jog_increment')
        self.g54inch = self.builder.get_object('g54inch_jog')
        self.g54tenth = self.builder.get_object('g54tenth_jog')
        self.g54hundredth = self.builder.get_object('g54hundedth_jog')
        self.g54thousandth = self.builder.get_object('g54thousandth_jog')

    def activ_inc(self, widget):
        if widget.get_active():
            if widget == self.g54inch: self.jog_increment.set_text('1.000')
            elif widget == self.g54tenth: self.jog_increment.set_text('0.100')
            elif widget == self.g54hundredth: self.jog_increment.set_text('0.010')
            elif widget == self.g54thousandth: self.jog_increment.set_text('0.001')

# This is boiler code, required for gladevcp
def get_handlers(halcomp,builder,useropts):
    return [HandlerClass(halcomp,builder,useropts)]

You should be able to change this to what you want

Thanks alot. Here is what I think I'll end up using.

import hal_glib
import hal
import pango

class HandlerClass:
    def __init__(self, halcomp,builder,useropts):
        self.builder = builder
        self.halcomp = halcomp

        self.g54thousandths = self.builder.get_object('g54thousandth_jog')
        self.zw_label = self.builder.get_object('zw_label')
        self.example_trigger = hal_glib.GPin(halcomp.newpin('label-trigger', hal.HAL_BIT, hal.HAL_IN))
        self.example_trigger.connect('value-changed', self.on_label_trigger_value_changed)
