I followed up on Bill's suggestion by writing this little routine. I don't
know how far back timer events go, but it works just fine under IDL 3.6.1.
Sadly, I am bound to version 3.0.0, which doesn't have timer events; I'll
just have to pass around the widget IDs and use WIDGET_CONTROL,/SHOW.

------------------------------------------------------------ -------------------

PRO LITTLE_EV, EVENT
WIDGET_CONTROL, event.id, GET_UVALUE = eventval
if eventval eq 'EXIT' then WIDGET_CONTROL,event.top,/DESTROY
if eventval eq 'POP_FRONT' then WIDGET_CONTROL, event.top, /SHOW, timer=1
end

PRO LITTLE
base = WIDGET_BASE(uvalue='POP_FRONT')
button = widget_button(base, value='EXIT', uvalue='EXIT')
WIDGET_CONTROL, base, /REALIZE
WIDGET_CONTROL, base, timer=1
XManager, "LITTLE", base, EVENT_HANDLER = "LITTLE_EV"
end
