Inheritance object → InteractionArguments
Properties¶
ScreenX¶
Gets or sets the X position, in map control coordinates.
public float ScreenX { get; set; }
Property Value¶
Remarks:
During a touch manipulation this is the position of the first finger the gesture reports, not the centre of the gesture. The centre is InteractionArguments.ManipulationOrigin, which is what a pinch or twist pivots around.
ScreenY¶
Gets or sets the screen Y position.
public float ScreenY { get; set; }
Property Value¶
WorldX¶
Gets or sets the world X position.
public double WorldX { get; set; }
Property Value¶
WorldY¶
Gets or sets the world Y position.
public double WorldY { get; set; }
Property Value¶
MouseButton¶
Gets and sets which button is clicked on the map canvas.
public MapMouseButton MouseButton { get; set; }
Property Value¶
CurrentExtent¶
Gets or sets the current extent used in the MapControl.
public RectangleShape CurrentExtent { get; set; }
