[Qgis-developer] Setting snapping settings via Python

[John Stevenson]

Hi,

Is there a way to set the snapping settings for a layer via Python?  I would like to turn on snapping with a specified tolerance automatically when a user begins editing within a plugin.

There is a question on gis.stackexchange, but it hasn't been answered.

http://gis.stackexchange.com/questions/133816/how-to-enable-the-snapping-options-for-vector-layer-using-the-python-programming

QSettings stores some values, but these are the defaults:

    qs = QSettings()
    qs.value('Qgis/digitizing/default_snap_mode')
    qs.value('Qgis/digitizing/default_snapping_tolerance')
    qs.value('Qgis/digitizing/default_snapping_tolerance_units')

I have also found the canvas.snappingUtils(), but cannot find functions there to enable snapping modes or set tolerances.

Thanks,
John
