MapMouseDownMapViewEventArgs¶

Namespace: ThinkGeo.UI.WinForms

Provides data for MapViewBase.MapMouseDown, exposing screen/world coordinates and the pressed mouse button.

public class MapMouseDownMapViewEventArgs : System.EventArgs

Inheritance object → EventArgs → MapMouseDownMapViewEventArgs

Remarks:

MapView-level notification fired once per physical mouse-down event, synchronously, before any InteractiveOverlay dispatch. Distinct from InteractiveOverlay.MapMouseDown, which fires only if dispatch reaches that overlay.
