Inside my Python plugin (qgis2.18) I use some Processing algorithms.

I'm trying to override the Processing setting that allows using only the selected features.
I' want to set it to False and following this answer I use that code inside my plugin before running Processing algs:

QSettings().setValue('/processing/configuration/use_selected', False)

Unfortunately after running my plugin Processing algorithms still working only with selected features.
But if I check Qgis settings I correctly see that :

Some hints about where I'm wrong?

I noticed that inside Processing own properties the checkbox is still checked (sorry for Italian menu) and I need to restart Qgis for applying changes.

    Does it work if you restart QGIS? – Joseph Sep 12 '18 at 10:08
  • Oh yes. Very disappointing. I can't ask to my users to restart Qgis... I even noticed that inside Processing own properties the checkbox is still checked after running my plugin. I've edited the question. – Oscar Campo Sep 12 '18 at 10:13

Try using the following which should change the settings directly within the processing framework (which can be seen in the properties window):

import processing
processing.ProcessingConfig.setSettingValue('USE_SELECTED', False)
