Provides access to Dynamic Display.
Product Availability
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.

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