Well, I think "vanishes" in the sense my wife usually
means it, in that she doesn't see it anymore because
it's gone behind some other window. I would say that it
is "hidden," as in a game of Hide and Seek.

Oh, well, this is the right solution, then, to the wrong
problem. In any case, I don't think it is likely to help you
solve this one.

I guess. I'd look at this fresh in the morning. I'll
bet it looks different then. ;-)

Well, the documentation says
"The WSHOW procedure exposes or hides the designated window."
and in the case of my window 12 example, it indeed "vanishes". Anyway,
here's the context:
PRO VIEWSEG_RUN, event
widget_control, event.top, get_uvalue=dn
envi_disp_query, dn, fid=fid, w1=w1, color=color
wshow, w1[1], 0 ; nothing happens
...
...
I call this from the ENVI display menu, so dn is is the number
corresponding to the display group, consisting of the image window (with
the display menu at the top), the zoom window (which I want to hide) and
the scroll window.
The reason I want to do this, is that I want to copy the content of the
image window to a pixmap _without_ the little red square that marks the
current position of the scroll window. Maybe that won't work anyway.
It's getting late in Old Germany ...
Cheers
Mort

Well, "vanish" is not what is meant by "hide", I don't
think. When the documentation says "show", they mean
bring the window to the front of the window stack. When
they say "hide", they mean move it down in the window
stack. It doesn't "vanish".
Maybe you want to make an icon of the window. That will
take it off the display and move it to the application bar
at the bottom (usually) of the display. Set the ICONIFY
keyword to WSHOW.
Cheers,
David

When I say
ENVI> window, 12
and then
ENVI> wshow,12,0
then window 12 vanishes. But in the case of the Zoom window, it just
sits there, defying me.

It works on my LINUX machine. What do you think
"hide" means in this case? I ask because I had to
work pretty hard to set up a situation where I
could tell whether this was working or not. I'm
not sure how often that would occur in practice.
Cheers,
David
