Hooray! I knew this had to be *somewhere*! Thanks!

Yeah, something like it. But here is a very simple
widget program. Running it produces *two* windows.
A window that looks like a normal IDL graphics window
and one that has a plot in it. The one that has the
plot in it is NOT the one that produces events when
I click in it. (This code is almost verbatim from
the on-line IDL help.) Any ideas?
PRO Test_EV, event
Help, event, /Structure
END
PRO Test
tlb = Widget_Base()
draw = Widget_Window(tlb, XSIZE=400, YSIZE=400, $
BUTTON_EVENTS=1)
Widget_Control, tlb, /REALIZE
Widget_Control, draw, Get_Value=window
window.select
p = plot(findgen(11), color='red')
XManager, 'test', tlb, /No_Block, Event_Handler='test_ev'
END
After I wrote this, I find that I can get it to work
if I set the CURRENT keyword on the plot function. But,
I thought window.select made that window the current window.
(This is what the on-line help says.) But I can't find a
select property for the window object in the help anywhere.
Any insight into this?
Thanks,
David
