I'm looking to change a number of QGIS settings with a python script. Whilst I can find references to some specific keys through various questions/answers on StackExchange, I can't find a method to actually look these up myself.

The question How do I access QGIS program settings programmatically? indicates that I need to go into the source code to look these up. However, I'm only a novice with this scripting stuff, and don't really know where to start or what to look for.

Can you provide a generalised set of steps for finding these keys in the source code?

  • Your question is broad, what specific setting are you interested in? See, docs.qgis.org/2.14/en/docs/pyqgis_developer_cookbook/…

  • @artwork21 Right now I'm interested in toggling "Auto Open Form". However, what I'm really after is a method for answering this question myself (if that makes sense). Then I won't have to post another question on SE the next time I want to find a key. Dec 18, 2017 at 21:50

You can use the QSettings::allKeys() method by first importing it:

from PyQt4.QtCore import QSettings


  • To get a list of current keys:

  • To print all keys individually (for readability):

    for keys in QSettings().allKeys():
        print keys
  • To search for a specific key:

    for keys in QSettings().allKeys():
        if 'Qgis' in keys:
            print keys
