Adding new function to python interface

Hi all,

I am trying to create a new GUI using GladeVCP. I found that I need a python file for NML interface. The list of available functions for python interface is provided in:

linuxcnc.org/docs/html/common/python-interface.html

However, what if I want to add a new function? For example, what if I want to create a new button on my GUI, and link my custom function to it? What is the source file for python interface functions?

Any help would be greatly appreciated

Regards,

Steve

well... I found from google that the source file is:

github.com/jepler/linuxcnc-mirror/blob/m...ensions/emcmodule.cc

That file is the one which provides python methods from C

Have you read JTs tutorial on GUI writing?
gnipsel.com/linuxcnc/gui/index.html

Also study the code in Axis, touchy, gmoccapy.

All the methods you need should already be available, primarily from importing 'linuxcnc'

ArcEye, thank you for your reply

I will check out JTs tutorial on GUI

I miss the remap level, homing status is wrong IMHO, etc,

Hi andypugh,

Actually, I am working on a project to create a LinuxCNC GUI which allows the users to display/adjust servo drive settings (such as filter cut-off frequencies or gains) and perform auto-tuning.

As far as I know, these features are not provided in LinuxCNC GUIs, and I understand that I may have to add a bunch of functions to LinuxCNC itself, as well as the GUI python script, to perform these tasks.

But, at this point, I'm not sure how the nml messages are handled in LinuxCNC, and which are the files that I need to modify.

I guess it is not an easy task...

Any suggestions?

regards,

Steve
