IDynamicDisplay Interface

Provides access to Dynamic Display.

Product Availability

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

Description

IDynamicDisplay interface gives access to drawing methods that render dynamic items using map coordinates, as well as access to an instance of the Dynamic Glyph Factory object. The Dynamic Glyph Factory object is a singleton object, which is used to create and delete dynamic glyphs and then can be used with the dynamic symbols in order to render the Dynamic items.

CoClasses that implement IDynamicDisplay

CoClasses and Classes Description
DynamicDisplay (esriCarto) Dynamic display class, used by the dynamic map.

Remarks

The IDynamicDisplay interface is passed in to the callback draw methods: IDynamicLayer.DrawDynamicLayer, IDynamicMapEvents.BeforeDynamicDraw, and IDynamicMapEvents.AfterDynamicDraw.

 

The drawing methods can only be used in one of the callback draw methods with the following specific context:

 

  1. In the IDynamicLayer.DrawDynamicLayer method.
    It is recommended to use the DynamicGlyphFactory in the esriDynamicDrawPhase.esriDDPImmediate dynamic-draw-phase.
  2. IDynamicMapEvents.AfterDynamicDraw method (event handler).
    Only with the dynamic-map-draw-phase esriDynamicMapDrawPhase.esriDMDPDynamicLayers.
  3. IDynamicMapEvents.BeforeDynamicDraw method (event handler).
    Only with the dynamic-map-draw-phase esriDynamicMapDrawPhase.esriDMDPDynamicLayers.

 

Any usage of the DynamicDisplay drawing API (or OpenGL API) in any other context will result in an unknown behavior.
