Python interface how to detect file is not open? was created by bladekel
Hello to all...
I'm trying to create a custom ui with python and I need to detect if an ngc file couldnt opened succesfully.
For this problem I'm using interpreter_errcode like;
self.s = self.emc.stat()
self.s.interpreter_errcode
but there is no return with this code..
Can anyone help me?

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import sys
import linuxcnc
try:
s = linuxcnc.stat() # create a connection to the status channel
s.poll() # get current values
except linuxcnc.error, detail:
print "error", detail
sys.exit(1)
s.file # returns the current loaded file

I might add that you should check the file name (using linuxcnc status) before you load the program, then check it after. If they are the same then the program probably loaded file.
eg gladevcp doe it like this (the code wont work for you but the idea is good):
def _load_file(self, filename):
if filename:
self.linuxcnc.mode(linuxcnc.MODE_AUTO)
old = self.gstat.stat.file
self.linuxcnc.program_open(filename)
if old == filename:
self.gstat.emit('file-loaded', filename)

self.linuxcnc.program_open(filename)
if old == filename:
self.gstat.emit('file-loaded', filename)
