The DisplayEvent class defines events that are fired by core.UMap class when the map display changes. It includes the following events:

  • DisplayEvent.UPDATE_POSITION: dispatched when map view has been updated.
  • DisplayEvent.UPDATE_ZOOM: dispatched when map zoom has been updated.
  • DisplayEvent.UPDATE_MAP_TYPE: dispatched when map type has been updated.

    public function DisplayEvent(type:String, latlng:LatLng = null, prevLatlng:LatLng = null, zoom:Number, prevZoom:Number, mapType:String = null, bubbles:Boolean = false, cancelable:Boolean = false)

    Creates a DisplayEvent object that contains information about events that are fired by core.UMap class when user interacts with the map. Event objects are passed as parameters to event listeners.

    Parameters
    type:String — The type of the event. Event listeners can access this information through the inherited type property.
     
    latlng:LatLng (default = null) — Specifies the position of the map center.
     
    prevLatlng:LatLng (default = null) — Specifies previous position of the map center.
     
    zoom:Number — Specifies map zoom level.
     
    prevZoom:Number — Specifies previous map zoom level.
     
    mapType:String (default = null) — Specifies the name of the map type selected.
     
    bubbles:Boolean (default = false) — Determines whether the Event object participates in the bubbling phase of the event flow. Event listeners can access this information through the inherited bubbles property.
     
    cancelable:Boolean (default = false) — Determines whether the Event object can be canceled. Event listeners can access this information through the inherited cancelable property.
