Add or Edit Binding The Add Binding dialog box allows you to create or edit a property binding. The following options are available:Source Object Specifies the owner of the source property. Source Property Specifies the source of the binding. Target Object Specifies the owner of the target property. Target Property Specifies the target of the binding. NOTE! Only properties of the same type as the source property type are listed. Allow cyclic binding Allows the target property to be set two times in the same context, which otherwise generates an error. NOTE! The target list box, besides dynamic properties also displays some common properties such as object transform that can only be used as target and not as source.Add or Edit Expression Binding The Add Expression Binding dialog box allows you to specify a mathematical expression as the source of a property binding. The following controls are available:Expression Specifies the mathematical expressions. The following lists the allowable mathematical expressions: • Allowed operators: +, - (unary and binary) *, /, ^ (power), Sin(), Cos(), Sqrt(), Atan() and Abs(). • Allowed operands: Numeric constants, PI, and Numeric dynamic properties on the current smart component and any child smart components
