All Implemented Interfaces:
com.vaadin.flow.component.AttachNotifier, com.vaadin.flow.component.DetachNotifier, com.vaadin.flow.component.HasElement, com.vaadin.flow.component.HasSize, com.vaadin.flow.component.HasStyle, Serializable, org.springframework.beans.factory.Aware, org.springframework.beans.factory.InitializingBean, org.springframework.context.ApplicationContextAware
public class GeoMap extends JmixMap implements org.springframework.context.ApplicationContextAware, org.springframework.beans.factory.InitializingBean
UI component that displays a geographical data provided by Layers.

The map is built by superposing layers. Initially, map does not have layers.

    • getMapView

      public GeoMapView getMapView()
      Overrides:
      getMapView in class JmixMap
      Returns:
      map view

    • setMapView

      public void setMapView(MapView view)
      Sets map view. It replaces previous default map view. To change zoom or center coordinate, use JmixMap.getMapView(), for instance: 
       map.getMapView().setZoom(10);
      Overrides:
      setMapView in class JmixMap
      Parameters:
      view - map view to set
      See Also:

    • setProjection

      public void setProjection(CRS projection)
      Sets the projection for coordinates supplied from and returned by API methods.

      Note, the projection will be used for all maps on the page.

      Parameters:
      projection - projection to set

    • getCenter

      public org.locationtech.jts.geom.Coordinate getCenter()
      Gets coordinates of the geographic center of the map's visible area.

      Delegates to the map's view. See getMapView().

      Returns:
      current center of the map's visible area

    • setCenter

      public void setCenter(org.locationtech.jts.geom.Coordinate center)
      Sets the geographic center of the map's visible area. Coordinates must be specified in the map projection, which is EPSG:4326.

      If the map projection has been changed using setProjection(CRS), then coordinates must be specified in that projection.

      Note that the map projection is a different concept than the view projection set in the map's GeoMapView. The view projection affects how map data is interpreted and rendered, while the map projection defines the coordinate system that all coordinates passed to, or returned from the public API must be in.

      Delegates to the map's view. See getMapView().

      Parameters:
      center - new center of the visible area

    • zoomToExtent

      public void zoomToExtent(org.locationtech.jts.geom.Coordinate bottomLeft, org.locationtech.jts.geom.Coordinate topRight)
      Sets a map's visible area that contains the given geographical bounds with the maximum zoom level possible.

      To zoom to an extent more advanced way, use fit(FitOptions).

      Parameters:
      bottomLeft - bottom left point coordinates of visible area (SouthWest)
      topRight - top right point coordinates of visible area (NorthEast)

    • zoomToFeature

      public void zoomToFeature(Feature feature)
      Sets a map's visible area that contains envelope of the geometry from given feature.

      This is the convenience method that delegates to zoomToGeometry(Geometry).

      Parameters:
      feature - feature from which geometry will be zoomed to

    • zoomToGeometry

      public void zoomToGeometry(org.locationtech.jts.geom.Geometry geometry)
      Sets a map's visible area that contains envelope of the given geometry with the maximum zoom level possible.

      To zoom to a geometry more advanced way, use fit(FitOptions).

      Note: if the given geometry is a point, map will be centered to this point with the current zoom level.

      Parameters:
      geometry - geometry to zoom

    • fit

      public void fit(FitOptions options)
      Fits the given geometry or extent based on the given map size and border and provided options. For instance, if it is needed to specify maximum zoom level and animation we can do the following: 
       map.fit(new FitOptions(feature)
     .withMaxZoom(9.0)
     .withDuration(1500)
     .withEasing(Easing.LINEAR));

      For more details see: View#fit() docs

      Parameters:
      options - options that configure zooming to an extent or geometry

    • addClickListener

      public com.vaadin.flow.shared.Registration addClickListener(com.vaadin.flow.component.ComponentEventListener<MapClickEvent> listener)
      Adds map click listener. Note, if the user makes double click on a map, the MapClickEvent will be fired twice.
      Parameters:
      listener - the listener to be added
      Returns:
      a registration object for removing an event listener

    • addSingleClickListener

      public com.vaadin.flow.shared.Registration addSingleClickListener(com.vaadin.flow.component.ComponentEventListener<MapSingleClickEvent> listener)
      Adds map single click listener. Single click means that an event won't be fired if the user makes double click.
      Parameters:
      listener - the listener to be added
      Returns:
      a registration object for removing an event listener

    • addDoubleClickListener
