QTDesigner PATH issue

Something tells me that this python reference to the os.path is incorrect?

Qtvcp python plugin found: /home/andy/.designer/plugins/python/qtvcp_plugin.py

Since OS is already included. Or perhaps the var isn't already defined?

This will because PATH.find_image_path() returned nothing.
Can you give any more information?

That's all that was returned. The GUI started but, without the Linuxcnc plugins.

It appears as if the ICONPATH either defaults to NONE or has been defined as NONE.
The frozen posixpath is referring to the built-in OS lib. 

Should this line be:
ICONPATH = os.path.join(INFO.LIB_PATH, 'images/probe_icons')

instead of:
 ICONPATH = os.path.join(PATH.find_image_path(), 'probe_icons')

I just haven't had time to fully test. I'll look into it later the afternoon if I get a chance.
 

is this a dev version? Did you run the . /scripts/rip before?

Yes and yes. 

ok find the file qt_pstat.py

change the line to:

# Force the log level for this module
LOG.setLevel(logger.VERBOSE) # One of DEBUG, INFO, WARNING, ERROR, CRITICAL

and try again - should print more info to the terminal.

I get the same error as I initially reported. 

It's also reporting:
WARNING: Recursive promotion of  "IndicatedPushButton"  to  "ActionButton" . A plugin is missing.
for each of the plugins used by qtvcp.

There was nothing else printed in the terminal after the code change?

Can you give more background? Has this ever worked?

Designer used to  run error free. I had a uspace install that I didn't realize existed. I suspect that once I removed
the uspace install, it may have impacted my RIP install.

I saw mention of QT needing some of the files that were in the DEB's.

I actually hard coded am abspath and that allowed me to get past the path issue.

However once I tried it from the local term I got these errors which don't exist, again the path and files don't exist:

FileNotFoundError: [Errno 2] No such file or directory: '/usr/share/qtvcp/widgets_ui/nurbs_editor.ui'

Where are the files coming from in /usr/share/qtvcp???

My guess is from these lines in pstat.py:

most every file uses SHAREDIR as a base.

If you open a terminal and type:
printenv LINUXCNC_HOME
does it return anything?

Somehow Qtvcp thinks that linuxcnc is installed rather then RIP.
