IFeatureClassDraw Interface

Provides access to members that set customized drawing properties.

Description

The IFeatureClassDrawinterface is an optional interface for feature class extensions, used to specify custom drawing behavior in ArcMap.

When To Use

Before a FeatureLayerdraws features in a feature class, it will check the FeatureClassExtensionfor support of this interface. Custom drawing can be achieved through the use of a custom renderer or through the use of a custom feature that implements IFeatureDraw::Draw.

Members

	Name	Description
	CustomRenderer	The custom renderer for the FeatureClass.
	CustomRendererPropPageCLSID	The custom renderer's property page CLSID.
	DoesCustomDrawing	Indicates whether the FeatureClass does custom drawing.
	ExclusiveCustomRenderer	Indicates whether the custom renderer is exclusive or not.
	HasCustomRenderer	Indicates whether the feature class has a custom renderer.
	RequiredFieldsForDraw	The required fields for drawing a Feature.

IFeatureClassDraw.CustomRenderer Property

Remarks

If using a custom renderer, the ExclusiveCustomRendererproperty can be used to restrict the available renderers to the custom one for the feature class. If the custom renderer is configurable, a configuration property page can be specified with the CustomRendererPropPageCLSIDproperty. If using a custom feature and that feature utilizes extra fields beyond the Shape for drawing, it is necessary to specify those fields in the RequiredFieldsForDrawproperty or they will not be returned in the FeatureLayer�s FeatureCursor.
