collapsed boolean | undefined experimental

Whether the control should start collapsed or not (expanded). Default to true.

collapseLabel string | Node | undefined experimental

collapsible boolean | undefined experimental

Whether the control can be collapsed or not. Default to true.

label string | Node | undefined experimental

Text label to use for the collapsed overviewmap button. Default is ». Instead of text, also a Node (e.g. a span element) can be used.

layers !Array.<ol.layer.Layer> | ol.Collection | undefined experimental

ol.control.OverviewMap.render(mapEvent) experimental

src/ol/control/overviewmapcontrol.js, line 214
This:
Name Type Description
mapEvent ol.MapEvent

Map event.

bindTo(key, target, opt_targetKey){ol.ObjectAccessor} inherited experimental

src/ol/object.js, line 326

The bindTo method allows you to set up a two-way binding between a source and target object. The method returns an object with a transform method that you can use to provide from and to functions to transform values on the way from the source to the target and on the way back.

For example, if you had two map views (sourceView and targetView) and you wanted the target view to have double the resolution of the source view, you could transform the resolution on the way to and from the target with the following:

sourceView.bindTo('resolution', targetView)
  .transform(
    function(sourceResolution) {
      // from sourceView.resolution to targetView.resolution
      return 2 * sourceResolution;
    },
    function(targetResolution) {
      // from targetView.resolution to sourceView.resolution
      return targetResolution / 2;
    }
  );

collapsible boolean

True if the widget is collapsible.

setMap(map){undefined}

src/ol/control/overviewmapcontrol.js, line 157

setTarget(target) inherited experimental

src/ol/control/control.js, line 138

This function is used to set a target element for the control. It has no effect if it is called after the control has been added to the map (i.e. after setMap is called on the control). If no target is set in the options passed to the control constructor and if setTarget is not called then the control is added to the map's overlay container.

listener function

The listener function.

this Object

Removes all bindings.

unByKey(key) inherited

src/ol/observable.js, line 114
