The fact it still works (I assume you are looking in 2.9 or master) is an anomaly.
You can't edit it with that latest GLADE editor and we should update it.
We don't guarantee any old panels will still work. Definitely won't work if you use python handler files.
As said.
linuxcnc 2.9 uses python3 and GTK3, so can use the latest GLADE editor.

What does that mean, "linuxcnc 2.9 uses python3 and GTK3, so can use the latest GLADE editor"? I'm great with that on my router, no problem. But I'm trying to follow these docs: linuxcnc.org/docs/2.9/html/gui/gladevcp.html
And in section 2.1 "Exploring the example panel" it refers me to manual-example, and that's the file I tried to open above.
So, is it just a case of stuff in 2.9 (and master) being obsolete? Is there a working example for GladeVCP so I can add UI to Axis?
For that matter, does Axis even use GTK+? Looking at src/emc/usr_intf/axis/axis.py, I see it imports Tkinter.Tk, and the UI still looks old, so I'm guessing it's Tk, and somehow magically incorporates GladeVCP plugins into its UI?
And can I use this from the run-in-place installation I currently have? The GladeVCP docs section 3.2 say "If LinuxCNC was not installed from a package, the LinuxCNC shell environment needs to be set up with <linuxcncdir>/scripts/rip-environment, otherwise Glade won’t find the LinuxCNC-specific widgets". That's an absolute path, and it's not at all clear where that XML tag should go; it doesn't even show it being closed. Grepping the source turns up no example of using it.

Unfortunately I don't think the docs have been updated completely. I see gtk2 on the page and that is old information.
Yes the example sims are old - looks like they run but can't be edited properly.
On my system (I use compiled RIP linuxcnc) glade 3.22 is used and it's gtk3 and it found the glade libraries.
ahh in the RIP script the path is exported:
if [ -z "$GLADE_CATALOG_SEARCH_PATH" ]; then
GLADE_CATALOG_SEARCH_PATH=$EMC2_HOME/lib/python/gladevcp
else
GLADE_CATALOG_SEARCH_PATH=$EMC2_HOME/lib/python/gladevcp:"$GLADE_CATALOG_SEARCH_PATH"
fi
Now I'll find where it should find them on an installed system and get back to you.

can you open :
/usr/lib/python3/dist-packages/gladevcp
and see if there is an XML file named hal_python.xml?
I have an installed version that is missing that file so won't load the widgets

so adding the file and setting the enviromental variable allowed me to see widgets.

You can set the catalog path in the preference file.
set it to look in:
/lib/share/glade3/catalogs

Alas, I don't have /usr/lib/python3/dist-packages/gladevcp on my system. I've only done the RIP, and I don't think I ever ran an install step.can you open :
/usr/lib/python3/dist-packages/gladevcp
and see if there is an XML file named hal_python.xml?
I have an installed version that is missing that file so won't load the widgets

Also, I'm now at my shop and able to look at my working real controller (not the sim on Debian 11 I've been talking about in this thread). It's running a 2.9-pre0 version I installed via package manager a couple years ago:
It uses axis for the DISPLAY, and some custom VCP I made a couple years ago that relies on GTK+2 (<requires lib="gtk+" version="2.24"/>). This currently works, but I seem to have glade-gtk2 installed on that machine. I'm guessing the GTK+3 change came after this build?
I'd love to update my linuxcnc and this machine, but I'm a bit nervous about how painful that might be. It's currently running Debian 10 (Buster).

I also don't have that directory. Is there a step I missed after doing the build for run-in-place?You can set the catalog path in the preference file.

Sorry I thought you were using an installed version.
RIP is easier to play with - I personally wouldn't use an installed version if I wanted anything customized.
Ya it's possible you had 2.9 (it would have been master at the time) before python3 was in.
I can't tell exactly when but 2021 sometime it looks like.
If your machine works I wouldn't touch it. I would build system on a a new harddrive so you can swap back if you need to.
