Classes that implement ISelectionEnvironment

Remarks

ISelectionEnvironment controls the way the selection is created and displayed. The application's selection environment is available via IMxApplication::SelectionEnvironment.

AreaSelectionMethod, LinearSelectionMethod and PointSelectionMethod define the spatial relations used to select interactively the different kinds of features. This is similar to the options found in the Selection Options dialog in ArcMap for the interactive selection but it can be set differently depending on the feature's geometry type.

Also a different search distance can be set for each type using the AreaSearchDistance, LinearSearchDistance and PointSearchDistance. These distance are used when searching by proximity for instance when using the IMap::SelectByShape method.

The CombinationMethod property defines how the selection performed will combine with an existing selection.

The DefaultColor property allows you to replace the default light blue of selected object with your favorite color.

The SearchTolerance property defines a global search tolerance to use for selection operations as exemplified in the IAnchorPoint example.
