I have a spatialite data base with 4300 polygons contained within. I wish to be able to edit the polygons but once i have highlighted the Polygon from the attributes table i find it hard to edit the vertices as when i try to select the cross hairs (vertex) unless i am extremely careful i end up selecting another polygon?

Is there a way of selecting the polygon i wish to edit from within the attributes table and making only that polygon editable? I know i could export it, edit it and then merge it back into the Spatialite database but this is additional steps that i would rather avoid if possible.

Any help or suggestions would be much appreciated.

I wonder would the snapping options help in this. –  Gerald Mar 7 '13 at 8:50

If you have a unique identifier, like a id field, you can copy that to the clipboard, close attribute table and editing mode, right-click on layer name -> Query, and fill in

"< fieldname>" = '< insert clipboard here>'

Keep an eye on single and double quotes. The query will return you the single item for editing.

Disadvantage is that you might get spaces between formerly fitting neighbouring objects.
