[Qgis-user] How to use the digitize tab in layer properties in QGIS 3.4

[Simon Haufe]

Dear QGIS-Users,

currently I am confused how to use the digitize tab in the layer 
properties. What is behind to check if a geometrie is valid or the 
topology has gaps, missing vertexes or is overlapping? The professional 
context I know pretty well. But what are the next steps in QGIS itself 
to show all the checking possibilities?

Background: QGIS 3.4 on Linux Ubuntu 18.04.

Thanks for all your answers.

Best regards
Simon Haufe
