Deinitialization

Deinitialization
is an option for Dynamic, DynamicModule, Manipulate and related constructs, which specifies an expression to be evaluated when the construct can no longer be displayed or used.

MORE INFORMATION

The typical usage is Deinitialization:>expr.

Deinitialization is typically done when the cell containing a construct is deleted, or when the notebook containing it is closed.

Deinitialization will never be performed unless initialization has previously been performed.

Deinitialization may be delayed if, for example, a construct appears in an invisible location such as the clipboard.
