Lathe Macros

It's looking non-trivial.
The new version uses a GTKOverlay which does not seem to be available in GTK2. It ought to be possible to use GTK3 (which exists for Buster) but then GladeVCP is not compatible.
Installing the 2.9 version of GladeVCP on Buster / 2.8 might work, but how?

I am about to try a search-and replace in the XML file to see what happens, but I don't expect much.

I have had some success, in fact I thought that I had it, but then saw that the speed and tool boxes have disappeared. These were in a GtkGrid pinned to the top right. And, you guessed it, GtkGrid isn't in Gtk2. So the editor was simply ignoring them. I might be able to put them in a GTKTable, but that's a fair bit of effort, and I am not sure how much you need it?Anyway, here is a modified Python handler (Py2 rather than 3) and .ui file (Gtk2 rather than 3). It works cosmetically with the same .svg and .ngc files,  but doesn't actually work as the system can't find the tool or surface speed any more.
Also, the run-button is not pinned to the bottom right any more.

This version only re-sizes the image when you change tabs. Which actually seems like something I might do to the other one, it appears that the expose_event happens very often.
 

Thanks Andy. How stable it 2.9? This machine is still in the project phase, and will be for a while still, so maybe it would be easiest to just upgrade to 2.9?

2.9 is reasonably stable, in fact I hope to split it off from Master for final stabilisation prior to release within the next few days. (and hopefully release will be before the end of this year) 

Let me know if you need any help with it, please.

I re-installed Debian11 incase i screwed something up, but this time ran into dependency loops and gave up after a few hrs.

I have now followed @tommylight Linuxcnc 2.9 on mint 21 a nd i have it running (much easier for me to see whats happening) but i still get the issue of the "cycles" tab not doing anything when clicked, suggesting im the problem lol.
I have tried with a working machine and the simulation machine in the link here lathe macros.

Could someone confirm im doing this properly, even for the simulation version?
Download all the simulation .hal and .ini from here lathe macros.
Create a simulated machine using the lathe_macros.ini
Launch simulated machine and check for errors
Download and place all the .ngc/.ui.py/.svg into home/neil/linuxcnc/nc_files/ (Should i have a new folder in here?)
Run machine using lathe_macros.ini
Confrim Estop, power and home machine, jog/mdi to check it simulates.
Click on "cycles" tab - nothing happens here
click on MDI, hide keyboard - no macros show

Here is grab of what terminal is showing whilst i try to make it work.
Only things jumping out at me, suggesting my paths are incorrect? I have tried putting things in various places and creating new folders and defining them in the .ini but same results..
