ISymbologyControlDefault Interface

Provides access to members that control the SymbologyControl.

Product Availability

Available with ArcGIS Engine.

Description

The ISymbologyControlDefault interface is the default dispatch interface that most development environments will automatically expose. For example, placing the SymbologyControl in a container will typically generate an object called SymbologyControl1. The properties and methods available directly on this object correspond to this interface, together with container specific properties and methods.

The ISymbologyControlDefault interface is a 'pure' dispatch interface, so can be extended with new properties and methods at future releases of ArcGIS. The methods and properties are identical to the highest numbered main interface on the SymbologyControl. For example, ISymbologySelectorDefault is equivalent to ISymbologyControl, but at future releases this could become ISymbologyControl2. By using the ISymbologySelectorDefault interface you are guaranteed to always have access to the latest SymbologyControl.

There is a small performance overhead in making calls through to a pure dispatch interface, but to avoid this you can QI to a specific interface. In some development environments it is not possible to QI directly on the control to other COM interfaces, because the control is contained within a wrapper object. Use the Object property to get the real control before performing the QI.
