critical problems while editing features

Reported by: giohappy Owned by: osgeo4w-dev@…
Priority: critical Component: Package
Version: 1.0 Keywords: QGis


It happens both on Stable and Unstable QGis on OSGeo4W distribution. The editing tools don't handle correctly mouse events/positions. In particular it seems that the editings after the first one feature don't grep the click coordinates but the last one of the first feature.

  • If one tries to create a new point layer every added feature geometry collapse on the same position of the first one added.
  • With lines after the first line is addes the followings get snapped to the last vertex of the preceeding line.
  • etc.

Obviously this doesn't happen on my Linux Qgis version...

Ouch! Tha'ts awful! It's due to the snapping options! If I simply open and close the snapping tab inside the Project Properties the specific layer snapping options are set, otherwise the deafult global options are used. In my experience the expected behaviour is different:

  • by default the global snapping options should be 0 (no snap)
  • if I want gloabl snap I can set it's value in the the Digitizing tab under Options
  • if I want to set per layer options it should require to flag the specific layer inside the Snapping Options window from Project Properties, and set the snapping value.

Otherwise, before digitizing in lat-lon, I have to do the extra step to change the dafult value (100) or open-close the Snapping Options window. The latter is a very strange, unexpected, behaviour!
