Most input widgets emit a signal when their value changes ("textChanged",
"currentChanged", "valueChanged", "clicked", etc). You could connect all of
the signals from the widgets to a single slot which resets the timer.

See both the Qt and PyQt docs on signals and slots.

I liked the suggestion about revalidating the user when the user presses
"ok" better though.
