UIDead

Returns whether the user interface is currently non-responsive, as a Boolean. Read-only.

Syntax: object.UIDead

object
required An object expression that evaluates to an AmbientProperties object.

The host sets UIDead to True when the application is in a state where it cannot meaningfully respond to user input — most commonly while execution is paused inside the debugger, but also during long modal operations. While UIDead is True a control should suppress animations, hover effects, and any input it would otherwise process, since the host’s main thread cannot deliver a useful follow-up.
