Hi, I think Sunburned Surveyor is correct.
"Item" refers to the way SelectionManager works (see the second and third button of the edition toolbox). Selection manager can select the whole geometry of a feature, or only a part of this geometry, or only a ring in a polygon in a multipolygon... Any of thoses things are called item. Martin or Jon will correct me if I misunderstood. @peppe : in french, I usually translate Feature as Object, Geometry as Geometrie, and Item as...hum not sure, most often "Element", but I may have changed depending on the context (Composant and Polyligne in the context of the editing toolbar) Michaël Sunburned Surveyor a écrit : > Acutally, I beleive there is a difference between the two (2) terms, > and a specific reason for using one and not the other in OpenJUMP. > Martin Davis or Jon Aquino could confirm what I am about to say. > > An "item" can refer to a feature that is part of a composite Feature > or FeatureCollection.
