Detect if window isn't active?

How would I detect when a window stops becoming active by, say, clicking on a different program's window? If GadgetDisabled(window)=True doesn't seem to work.

In the Docs, look for "Event Objects" Event Messages to look at are:

EVENT_APPSUSPEND
EVENT_APPRESUME

    WaitEvent()
    Select EventID()
    Case EVENT_APPSUSPEND
     ' Your app no longer is the active window.
    Case EVENT_APPRESUME
     ' Your app is now the active window.
    End Select
