IDisplayEvents Interface

Provides access to members that control Display Events.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

When To Use

Use this interface to trap for specific events occurring inside a display.  For example, you may wish to know whenever a particular display is scrolled.  This is the case for the Map object which needs to perform some redrawing operations whenever its screen display is scrolled.
