BUILT-IN MATHEMATICA SYMBOL

DynamicWrapper

represents an object that displays as e, but dynamically updates the expression expr whenever that object is visible on screen.

The displayed e is not treated as dynamic, although it can contain explicit Dynamic expressions.

When used to display e in a notebook, DynamicWrapper is effectively equivalent to Dynamic[expr;Refresh[e, None]].

Display static content while dynamically updating an expression:

Assign a value to the independent variable above:

Display static content while dynamically updating an expression:

The same constructs which control evaluation in Dynamic work in DynamicWrapper:

The first argument can contain a Dynamic, which may interact with the DynamicWrapper evaluation:

Unlike Dynamic, DynamicWrapper cannot be used as an argument to a control:

DynamicWrapper will only update its computation while being displayed:
