DynamicWrapper
DynamicWrapper[e,expr]
represents an object that displays as e, but dynamically updates the expression expr whenever that object is visible on screen.
Details and Options
- The displayed e is not treated as dynamic, although it can contain explicit Dynamic expressions.
- The expression expr is not displayed anywhere.
- DynamicWrapper has the attribute HoldRest.
- DynamicWrapper takes the same options as Dynamic.

Scope (3)
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:
Properties & Relations (3)
As with Dynamic, a DynamicWrapper will not evaluate its contents if it is not displayed:
CompoundExpression in a Dynamic can be used to evaluate multiple expressions:
DynamicWrapper instead resolves its first argument at the time ![TemplateBox[{shift, return}, Key1, BaseStyle -> {ExampleText, FontWeight -> Plain, FontFamily -> Source Sans Pro}]](Files/DynamicWrapper.en/1.png "TemplateBox[{shift, return}, Key1, BaseStyle -> {ExampleText, FontWeight -> Plain, FontFamily -> Source Sans Pro}]"){kind=small}
is pressed:
Initialization sets an evaluation that will only happen a single time at Dynamic creation:
DynamicWrapper sets an evaluation that may happen repeatedly:
Possible Issues (1)
DynamicWrapper will only update its computation while being displayed:
