Adding Flexibility using Parameters

INDEX PREVIOUS NEXT

By default, an object uses static values to control its size. For example, the progressbar object created in Working with Symbols has a minimum width of 0 and a maximum width of 120. The transformation added in Transforming an Object still leaves the maximum at 100. To create re-usable symbols, the best practice is to use parameters to control size. This way, the size of a symbol can be easily adjusted for inclusion in a symbol with different dimensions.
