QTvcp copy Error was created by Samas322

Hi I just tried to copy the QTplasmaC GUI to modify it but as soon as i copy it in the machine directory (by using "qtvcp copy" in the terminal, and before i attempt any modification) QtplasmaC wont launch and send me this error. i tried it with a clean installation also and still not work. i also try the same thing with qtdragon but this time it worked. it seams to be an error in qtplasmac_handler.py but im not sure. can anyone help me please?

Ok so i removed few spaces in front of the elif just before the "os.rmdir..." around line 2390 and now it seems to work but im not sure if i fixed it or if i bypassed some feature! Anyway it will need to be fixed for future updates.

To help figure out the root cause, and how to address it, can you tell me what's still in the directory?

Its the copy of the gui that i made with "qtvcp copy" for editing it. As i tell you i removed spaces in front of the else before this line and it solved the probleme. I think the else have been moved accidently. This section of code i think is for unlink the original handler.ini file and use the copied one in this directory. For whatever reason it tried to delete this folder.
finaly it is not supposed to delete the folder.

It IS supposed to delete the folder. qtplasmac as a symlink, or a directory should not exist inside of a config folder anymore, this is something we used in the past. You are getting the error because the folder is not empty, which is something I did not expect when I added that line of code.

I am asking what is in that particular folder, as I want to understand this edge case before I change the code to just delete the directory regardless of its contents.

Can you copy and paste the results of the following terminal command:

ls /home/ssm/linuxcnc/configs/sim.qtplasmac/qtplasmac

Hey Sam, thanks for the video, I wasn’t previously aware of qtvcp copy. So it’s definitely creating an edge case we didn’t know to plan for.

I’ll work with Phill on the side and come up with a solution here.

Ctrl+r will do cycle start by the way. For things that cause motion we chose a two key combo intentionally so you don’t accidentally start motion if you drop something on the keyboard, etc. It’s always interesting to see people’s use cases for things, but wanted to toss the thought process out there for choosing two keys instead of just one to start motion.

On a similar note, space bar was chosen to pause motion once it’s already started because it’s easy to “dive” for and hit when you see something going wrong.

Yes i already know for the ctrl+r but like to use the space bar and for safety i added a 2 second delay when you press for cycle start and 1 second for cycle resume. For my self i like it that way! In the future it would be nice to implement an easy way to change keyboard shorcuts! Have a nice day!
