Qtdragon NGCGui not rendering UI

[ihabmmali]

Here are the steps I follow to reproduce the issue:

1. Compile latest version of linuxcnc 2.10 from git source
2. Launch the qtdragon_hd sim configuration
3. Navigate to Utils->NGCGUI Tab

This is what I expected to happen:

See the usual NGCGui dialogue for creating features

This is what happened instead:

We get an empty table with a single line text input box that seems to be disabled:

It worked properly before this:

Pre 2.9->2.10 merge

Can you run in a terminal and see if there are relative debug information?

[ihabmmali]

I have been running from command line and I cant see any unusual debug level errors:

Interestingly, if I destroy the tabs and create a new one and load the same ngcgui sub file then it works:

I then get these additional debug lines in the terminal

I played around with the ini and changed the NGCGUI_SUBFILE_PATH from the default of the sim file to the fully qualified path(so ~/linuxcnc/nc_files/examples/ngcgui_lib instead of the relative file path ../../../nc_files/ngcgui_lib/) and the ngcgui tabs load properly. I think it wasn't actually finding the sub files when using the relative path because the relative path had an extra "../". I think error handling is probably not working as expected? I guess it shouldn't attempt to create the tabs if the files are not found.

And sorry I just noticed it wasn't actually finding the files even in the previous screen shot...should have caught the error and corrected the path.

Ok tha's for that. I think it would be better if it showed a message on the tab that the path couldn't be found.

[c-morley]

My guess here is that as installed files get removed around, the relative path doesn't point in the right place anymore - it works fine in RIP. I'll try to get back to this.
