Detailed Description

Switch between different representations.

Library: ilvproto

IlvMultiRepAccessor is used to build symbols that have multiple representations depending on a state value. This accessor controls the visibility of the nodes of a group depending on an integer value that represents a state. When the value is changed, the graphic node corresponding to the new value is made visible, and the nodes corresponding to other values are hidden.

Constructor & Destructor Documentation

IlvMultiRepAccessor::IlvMultiRepAccessor	(	const char *	name,
		const IlvValueTypeClass *	type,
		IlUInt	count,
		const char **	nodenames
	)

Creates a new multi-representation accessor.

The values of this accessor can range from 0 to count-1. When the value is changed, it is used as an index in nodenames to find the node that is to be made visible. All other nodes in nodenames are hidden.

Parameters

name	Name of the attribute.
type	Type of the attribute. It should be an integer type such as IlvValueIntType.
count	Number of possible values.
nodenames	Array of names of graphic objects included in the group
