Méthode Description
OnApplyTemplate ( ) : void

When overridden in a derived class, is invoked whenever application code or internal processes (such as a rebuilding layout pass) call M:System.Windows.Controls.Control.ApplyTemplate. In simplest terms, this means the method is called just before a UI element displays in an application.

Private Methods

Méthode Description
GetBestEstimateOfValue ( double resolution, ScaleLineUnit displayUnit, ScaleLineUnit &unit, double &outResolution ) : double
GetResolutionForGeographic ( MapPoint center, double resolution ) : double

Calculates horizontal scale at center of extent for geographic / Plate Carrée projection. Horizontal scale is 0 at the poles.
InitializeMapUnit ( ) : void

Try to initialize the map units
Map_PropertyChanged ( object sender, PropertyChangedEventArgs e ) : void
OnMapPropertyChanged ( DependencyObject d, System.Windows.DependencyPropertyChangedEventArgs e ) : void
OnMapPropertyChanged ( Map oldMap, Map newMap ) : void
OnMapUnitPropertyChanged ( DependencyObject d, System.Windows.DependencyPropertyChangedEventArgs e ) : void
OnPropertyChanged ( string propertyName ) : void
OnTargetWidthPropertyChanged ( DependencyObject d, System.Windows.DependencyPropertyChangedEventArgs e ) : void
RefreshScaleline ( ) : void

Refreshes the scaleline when the map extent changes.
RoundToSignificant ( double value, double resolution ) : double

Rounds to a value to the significant number of digits.
ScaleLine ( ) : System

Static initialization for the ScaleLine control.
SetDesignValues ( ) : void

Sets the design values.
map_ExtentChanged ( object sender, ExtentEventArgs args ) : void

Handles the ExtentChanged and ExtentChanging event of the map control.
