UiContourReleaseAction class

One action released by a UiContourRelease trigger.

A null onPressed renders a genuinely disabled control — correct appearance, pointer behavior, focus behavior, and semantics all come from UiIconButton's own disabled contract. UiContourRelease never substitutes a non-null closure for a null callback.
