Type Definitions

FilterFunction()

A function that takes a Feature and returns true if the feature may be selected or false otherwise.

Options{Object}

Properties:
Name Type Description
addCondition Condition | undefined

A function that takes a MapBrowserEvent and returns a boolean to indicate whether that event should be handled. By default, this is never. Use this if you want to use different events for add and remove instead of toggle.

condition Condition | undefined

A function that takes a MapBrowserEvent and returns a boolean to indicate whether that event should be handled. This is the event for the selected features as a whole. By default, this is singleClick. Clicking on a feature selects that feature and removes any that were in the selection. Clicking outside any feature removes all from the selection. See toggle, add, remove options for adding/removing extra features to/ from the selection.

layers Array<Layer> | function | undefined

A list of layers from which features should be selected. Alternatively, a filter function can be provided. The function will be called for each layer in the map and should return true for layers that you want to be selectable. If the option is absent, all visible layers will be considered selectable.

style StyleLike | null | undefined

Style for the selected features. By default the default edit style is used (see Style). Set to null if this interaction should not apply any style changes for selected features. If set to a falsey value, the selected feature's style will not change.

removeCondition Condition | undefined

A function that takes a MapBrowserEvent and returns a boolean to indicate whether that event should be handled. By default, this is never. Use this if you want to use different events for add and remove instead of toggle.

toggleCondition Condition | undefined

A function that takes a MapBrowserEvent and returns a boolean to indicate whether that event should be handled. This is in addition to the condition event. By default, shiftKeyOnly, i.e. pressing shift as well as the condition event, adds that feature to the current selection if it is not currently selected, and removes it if it is. See add and remove if you want to use different events instead of a toggle.

multi boolean
(defaults to false)

A boolean that determines if the default behaviour should select only single features or all (overlapping) features at the clicked map position. The default of false means single select.

features Collection<Feature> | undefined

Collection where the interaction will place selected features. Optional. If not set the interaction will create a collection. In any case the collection used by the interaction is returned by getFeatures.

filter FilterFunction | undefined

A function that takes a Feature and a Layer and returns true if the feature may be selected or false otherwise.

hitTolerance number
(defaults to 0)

Hit-detection tolerance. Pixels inside the radius around the given position will be checked for features.
