Remarks

A CompositeGraphicsLayer manages a collection of graphics layers.

An example of a composite graphics layer is the Map’s basic graphics layer accessed through IMap::BasciGraphicsLayer. It is both a graphics layer on which to draw and a composite graphics layer which contains all the map's graphic layer. The Map’s basic graphics layer cannot be deleted from the CompositeGraphicsLayer object. Get a reference to the map's basic graphics layer throught the ICompositeGraphicsLayer interface to manage the layer it contains. This way, graphics layers can be added to or deleted from the map.

The ICompositeGraphicsLayer interface inherits from the IGraphicsLayer interface.

[Visual Basic 6.0]

The following example is a code excerpt that shows how to get a reference to an ICompositeGraphicsLayer interface with Visual Basic.

'This example assumes that you already have an IMap (pMap) set

' get ICompositeGraphicsLayer
  Dim pCompGraLyr As ICompositeGraphicsLayer
  Set pCompGraLyr = pMap.ActiveGraphicsLayer
