Открытые методы

Метод Описание
GpsLayer ( ) : System

Initializes a new instance of the GpsLayer class.
Initialize ( ) : void

Initializes the resource.

Override this method if your resource requires asyncronous requests to initialize, and call the base method when initialization is completed.

Upon completion of initialization, check the P:ESRI.ArcGIS.Client.Layer.InitializationFailure for any possible errors.

Защищенные методы

Метод Описание
OnMapChanged ( Map oldValue, Map newValue ) : void

Override to know when a layer's Map property changes.

Приватные методы

Метод Описание
AttachListeners ( IGeoPositionWatcher geowatcher ) : void
BeginAnimateLocation ( MapPoint newLocation ) : void
DetachListeners ( IGeoPositionWatcher geowatcher ) : void
GeoPositionWatcherPropertyChanged ( DependencyObject d, System.Windows.DependencyPropertyChangedEventArgs e ) : void
GetAccuracyInMapUnits ( ) : double

Gets the horizontal accuracy in map units.
GetAccuracyInMapUnitsFromScale ( ) : double
GetMapUnits ( ) : string

Gets the map units from the map. This requires the map to be in either WGS84 or WebMercator spatial reference, or have at least one ArcGIS layer whos default spatial reference matches that of the map.
GpsLayer_PropertyChanged ( object sender, PropertyChangedEventArgs e ) : void
OnAccuracyCircleSymbolPropertyChanged ( DependencyObject d, System.Windows.DependencyPropertyChangedEventArgs e ) : void
OnGeoCoordinatePropertyChanged ( DependencyObject d, System.Windows.DependencyPropertyChangedEventArgs e ) : void
OnGeometryServiceUrlPropertyChanged ( DependencyObject d, System.Windows.DependencyPropertyChangedEventArgs e ) : void
OnIsEnabledPropertyChanged ( DependencyObject d, System.Windows.DependencyPropertyChangedEventArgs e ) : void
OnLocationMarkerSymbolPropertyChanged ( DependencyObject d, System.Windows.DependencyPropertyChangedEventArgs e ) : void
TryStartGps ( ) : void

Attempts the start the geowatcher.
UpdateAccuracyCircle ( ) : void

Starts animation of the circle
UpdateLocation ( ) : void

Starts animating the location.
UpdatePosition ( GeoPosition position ) : void
animationTimerAccuracy_Tick ( object sender, EventArgs e ) : void

Handles the Tick event of the animationTimerAccuracy timer and animates radius of the accuracy circle.
animationTimerLocation_Tick ( object sender, EventArgs e ) : void

Handles the Tick event of the animationTimerLocation timer and animates the location point and center of the accuracy circle.
map_PropertyChanged ( object sender, PropertyChangedEventArgs e ) : void
quinticEaseOut ( double t, double b, double c, double d ) : double
watcher_PositionChanged ( object sender, GeoPositionChangedEventArgs e ) : void

Handles the PositionChanged event of the watcher control.
watcher_StatusChanged ( object sender, GeoPositionStatusChangedEventArgs e ) : void

Handles the StatusChanged event of the watcher control.
