Launching gladevcp panel with gmoccapy

I'm struggling to launch a gladevcp panel from my gmoccapy interface. I've queried the web for examples and feel that I'm on the right track, but without success.  I'm open to any suggestions.

I've attached my .ini file along with my gladevcp.ui and custom_postgui.hal for reference.

FYI - I have a laser crosshair that I use to locate the program start for a project. The laser can be toggled by either the gladevcp panel or via a toggle switch on the machine. I've wired up the machine such that either source will set an input pin high to turn on the panel LED. If the laser is toggled via the machine toggle, I want a visual indicator to remind me to turn it off manually.
Once I get the panel to display and the led to toggle properly, I may split the input to I get a visual indicating which source toggled the LED, but for now I just want to get the panel up and working. There is no custom python handler needed at this time.

EMBED_TAB_LOCATION = ntb_preview
or
EMBED_TAB_LOCATION = ntb_user_tabs

Did you try these?

Also new 2.10 will not start with your .ini configuration having names with hyphens, use underscores

Yes, I've tried both, neither surfaced the gvcp panel with gmoccapy.

 

Several errors.

1. A typo. You wrote "EMBED_TAB_HAME = CROSSHAIR" instead of "EMBED_TAB_NAME = CROSSHAIR". Unfortunately you don't get an error because the interpreter just thinks "this value is not for me".
2. you need to define where the VCP should be shown like Aciera mentioned, e.g. 
Then you get a meaningful error message

This points out that you used an old glade editor. Saving it with a up-to-date Glade 3 editor (3.40 e.g.) removes this and other obsolete properties.

Then the VCP is displayed:

 

Further you have a handler "on-changed" defined in your glade (ui) file, but no python file where this handler is defined
