Map Display (ui::MapDisplay)

The Map Display component renders as an OpenStreetMap with the defined center location, zoom, and optionally also markers. You can drag the map to change the visualized area and zoom it in and out. The map markers can be draggable.

It produces events of the following types:

• InitEvent when the component is initialized or displayed if previously hidden
• MapClickedEvent when the user clicks the map
• MarkerClickEvent when the user clicks a map marker
• MarkerDraggedEvent when the user drags a marker

Map Properties

• Center: coordinates of the center of the rendered map
• Zoom: default zoom on initialization and refresh defined as an integer with value 0-18 (0 being the lowest zoom with the entire Earth displayed)
• Markers: set of business data that are used as map markers

  { 
    [new Meeting(
            title -> "Whitestein Meeting",
            location -> whitesteinHeadquarters,
            can_reschedule -> false,
            attendees -> ["Vladimir", "Estragon"]
            ] 
  }
  

• To marker: expression that converts the business data from Markers to MapMarker objects

  { x:Meeting -> new ui::MapMarker
    (
      title -> x.title,
      location -> x.location,
      popup -> x.title + "<br/>Atendees: " + x.attendees,
      draggable -> x.can_reschedule
    )
  }
