Object Model: ActionDeltaItem.Value

ActionDeltaItem.Value

Description

Sets or returns the value of an ActionDeltaItem. Depending on the type of the ActionDeltaItem (see siModificationDeltaType), this property sets or returns different types of values:

- For siModificationDeltaFCurves, sets/returns FCurves

- For siModificationDeltaStaticValue, sets/returns Doubles

- Otherwise, sets/returns String

C# Syntax

// get accessor
Object ActionDeltaItem.get_Value();
// set accessor
ActionDeltaItem.set_Value( FCurve out_pvValue );
