<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Thanks for help so far.<br>
<br>
These suggestions seem to be more complicated than I require. I do not need to use the snapper to modify geometries in a custom tool, just to turn snapping on for the current layer when the user begins editing it. I tried the following, based on Etienne's
inasafe example, but nothing happens:<br>
<br>
layer = canvas.layer(0)<br>
point_locator = QgsPointLocator(layer)<br>
units = QgsTolerance.LayerUnits<br>
layer_config = QgsSnappingUtils.LayerConfig(layer, point_locator.Types(), 50, units)<br>
snapper = QgsSnappingUtils()<br>
snapper.setLayers([layer_config])<br>
snapper.setSnapToMapMode(QgsSnappingUtils.SnapAdvanced)<br>
<br>
Is there another snapper already created by QGIS when editing begins that I can access?<br>
<br>
Cheers<br>
John<br>

<div>Hi,<br>
<br>
I'm maybe wrong but you'd better look at QgsSnappingUtils <a href="http://qgis.org/api/classQgsSnappingUtils.html" target="_blank">
http://qgis.org/api/classQgsSnappingUtils.html</a><br>
</div>
<div>It seems more simple and should do the job for you.<br>
