NGCGUI and GCMC from the PyNgcGui GladeVCP widget was created by phillc54
I am attempting to use GCMC scripts through the PyNgcGui GladeVCP widget in a custom python GUI running LCNC 2.7.4.
In my ini file I haveas noted
here
plus I haveas noted in the sample configuration. (this path IS the correct path for my installation)
All NGCGUI subs run as expected and the result appears correctly in the Gremlin display with the following message in the terminalhowever when I try a GCMC script I get the following output in the terminal when I click 'Create Feature'and then after I click 'Finalize' a dialog box appears with 'No features specified on this page' as the message.
Is this a limitation of the PyNgcGui widget or am I doing something wrong?
In my ini file I have
[DISPLAY]
GCMC_INCLUDE_PATH = ../ngcgui/gcmc_lib
[RS274NGC]
SUBROUTINE_PATH = ../ngcgui/gcmc_lib
All NGCGUI subs run as expected and the result appears correctly in the Gremlin display with the following message in the terminal

see if pyngcgui.py is infact located at /usr/lib/pymodules/python2.7/pyngcgui.py"
i have a feeling that it could be set up to use python2.6 and your using 2.7 etc .
or at least it thinks it want to use 2.7 etc .

Yes it is.
GCMC via NGCGUI does work when I run the sample called pyngcgui-gcmc-demo which uses the Axis GUI but that doesn't use the PyNgcGui widget, it uses an embedded tab.

Please post more information:
1) What linuxcnc version?
2) How was linuxcnc installed (deb or run-in-place)?
3) What gcmc version?
4) Try this sim config and report:
Sample Configurations/sim/gscreen/ngcgui/pyngcgui_gscreen_gcmc
5) Attach a tar or zip file of the complete configuration you
are testing
6) Attach a complete transcript of the shell command sequence and
the errors

I see no sim config with that name, please give exact name.I run the sample called pyngcgui-gcmc-demo
Please post more information:
1) What linuxcnc version?
2) How was linuxcnc installed (deb or run-in-place)?
3) What gcmc version?

Sorry, I just read the sample config name from the desktop icon, I should have said:LinuxCNC is version 2.7.4 originally installed the from linuxcnc-2.7-wheezy.iso and allowed to do updates.GCMC version is 1.7.2Running the sample config you suggested works fine, as does the sample config above.
I tried removing the PyNgcGui widget from my Glade file and just running pyngcgui as an embedded tab in my GUI and it comes up with exactly the same error message so I guess I have something not right in my GUI.
The session went as follows:The last two lines are a NGCGUI sub that was successfully sent after the GCMC scipt faulted which happened as soon as I clicked 'Create Feature' in the NGCGUI dialog.
Full config is attached

Thanks for including the complete config. I've tested using
gcmc 1.7.2, debian jessie, 64bit, uspace with current 2.7 in
a RIP build (commit 01e4bb6 2016-06-08) and with a recent
deb: linuxcnc-uspace_2.7.4.105.gf281232_amd64.deb (commit
f281232 is 6/16/16) but have not been able to reproduce the
problem.
I have not ruled out some system dependency as your system
is different than mine (32bit rtai, wheezy vs 64bit uspace,jessie)
I tested the following way:
I tested with the cpocket tab i added and by specifying
cpocket using the custom tab to find the same cpocket.gcmc
file.
So i'm not sure what is different. Your config is very
complicated so you might try making a much simpler sim
config to isolate the problem.

Thanks for checking this for me.
In my setup I didn't have a GCMC script as a NGCGUI_SUBFILE in the ini file so after looking at your results I added one and observed the following:
If I add any GCMC script as a NGCGUI_SUBFILE in the ini file it works.
If I don't have a GCMC script as a NGCGUI_SUBFILE in the in file it errors as described previously.
Omitting any or all NGC files as a NGCGUI_SUBFILE in the ini file makes no difference at all.
So all I need to do is leave at least one GCMC script as a NGCGUI_SUBFILE in the ini file.

This was a bug, should be fixed for next 2.7 release with this commit:
git.linuxcnc.org/gitweb?p=linuxcnc.git;a...08d624f52e292497b34b
Thanks for the bug report.
Nice work on your custom gui !
