Call external programmes from python plugin in QGIS on windows

Question

I need to call an external programme from python plugin in qgis, I didn't use os.systeme because I want to hide the launched programme with 'startupinfo.dwFlags |= subprocess._subprocess.STARTF_USESHOWWINDOW'.

import subprocess
import os
startupinfo = None
if os.name == 'nt':
    startupinfo = subprocess.STARTUPINFO()
    startupinfo.dwFlags |= subprocess._subprocess.STARTF_USESHOWWINDOW
subprocess.Popen("TeighaFileConverter",shell=True, stdin=None, stdout=PIPE, stderr=PIPE,startupinfo=startupinfo)

it's workin on pyzo but not working in QGIS editor.
this code is working on linux but not on windows :/

Answer 1

you could also try subprocess.call

subprocess.call(["TeighaFileConverter"])

and make sure that you have the path to your TeighaFileConverter installation in you path variable

EDIT:

I tested the code above again in the python console in qgis and it didn't work, sorry for posting a wrong code, you have to mention the whole path in order to call it

subprocess.call(['C:/Program Files (x86)/ODA/Teigha File Converter 4.3.2/TeighaFileConverter.exe'])
