[Qgis-user] QGIS Actions

[Richard McDonnell]

Morning,
Just a progress report!
Ive found another way of doing it, but it causes QGIS to hang (become 
unresponsive) for about 2mins

import subprocess

subprocess.call(['C:/Program Files/Autodesk/AutoCAD 2015/acad.exe', ' 
"[% "root" %]itm/[% "subfolder" %][% "filename" %]" '])


Its cleaner than the clunky option, but what I am doing that's causing 
QGIS to hang, well after the file has opened in the CAD program.

The above is not an ideal solution either, as it uses a direct link to 
AutoCad, as opposed to using the system default program like the Open 
Action does.


Regards,

Richard.
