Class Select

Classdesc

Interaction for selecting vector features. By default, selected features are styled differently, so this interaction can be used for visual highlighting, as well as selecting features for other actions, such as modification or output. There are three ways of controlling which features are selected: using the browser event as defined by the condition and optionally the toggle, add/remove, and multi options; a layers filter; and a further feature filter using the filter option.

Selected features are added to an internal unmanaged layer.

Param: opt_options

    Revision.

    Api

Static handleEvent

  • handleEvent(mapBrowserEvent): boolean

  • Handles the map browser event and may change the selected state of features.
