I'm sure they assumed, when IDL ballooned up from
30K of process space to 30,000K, that IDL would
be the only application running on your computer. ;-)

ha, it was about 5 minutes, so that might be true.
What it seems like is that IDL is assuming there are no other windows
present, or that at least that the IDL related windows are all in the 'next'
alt-tab queue.

Well, I don't know. Following your directions, I can't make
it pull up another application at all, but I sure have seen
that happen. I'm using the Windows 8.1 version, is that what
you are using?
You may be on the right track though, because creating a
widget program before calling WShow might rearrange the
order of windows enough to put the graphics window in
the right position occasionally.
I'm pretty sure you have done more research on this
topic than ITTVIS. Maybe you should contact them. :-)

I suspect it is a specific and predictable application that is being brought
up.
Bring the IDLDE up front. Hit alt-tab and hold it down (keep the alt key
pressed), so you have the little box showing you the icons of all the active
programs. Then, while keeping the alt key down, hit esc to cancel the
alt-tab window. That will show you the order of all the windows that exist.
This random app, is always the one in the second spot, assuming IDLDE is the
first spot. Then, type wshow (IDLDE is still active) and bammo, the IDL
gets moved to the spot of window0, and what was in the second spot (in the
alt-tab window) is the new application.
That is the error in wshow. it is moving the current window to the
idlwindow0 position (and it should do it the other way around, move the
idlwindow0 position to the current window position). maybe :)

Oh, yeah, I forgot to mention that 25% of the time
some other application comes to the front when you
type WShow!! And the other 50% of the time you
don't have the faintest idea what is about to happen!
It's fun! Endless entertainment when you are stuck
in front of a class full of students. You can take
bets if it's really slow. :-)

I have done this a couple of times (in an existing IDL session) but what I
see is that I can create the window, then put "another app" in front of it,
then select the IDLDE to type wshow, then wshow will bring that "other app"
to the front.
So here is the hypothesis. IDL uses the wshow command to switch the order
of the windows in the operating system alt-tab q. For instance, I have
IDLDE as the first app (current, on top, active) several other programs,
then the idl window0 at the 7th spot. I type wshow, and IDLDE becomes the
7th spot, everything else moves up 1 (idl window0 is then 6th). The most
recent "other app" was in the second spot, and it moves to the first spot
and appears on top.
So, in terms of the windows7 alt-tab queue, seems to me that the action of
wshow's error is that instead of moving window0 to 'zero', it is moving the
IDLDE
to the spot of the window0. Should be easy enough to fix.
cheers,
bob
PS, it's a bit different with another IDL window (i.e. the xcolors widget),
but I don't have the time to really look at that.

Well, the Coyote Graphics equivalent would be
cgShow, but alas, the Coyote Graphics rely on
the underlying IDL programs working correctly.
So, no, it wouldn't help in this case.
The problem is there is no reliable way to
bring a direct graphics window forward on the
display any longer. :-(
In IDL 8.1 for example, I type this:
window
Now, I hide the window behind another application,
and type this:
wshow
This command does nothing. But, if I do this:
xcolors
wshow
The window 0 pops forward!! This works about
25% of the time and for God only knows what
reason. :-)

David

On an unrelated note, my IDL eyes cringe at that FOR loop. ;-) Here's
an easier version of the paragraph under ";graph that line!"
nx = 51
x = findgen(nx) / (nx-1)
y = p[1]*x + p[0]

WSet!? Goodness. I'm getting more senile than I
thought! I mean, of course, WShow. Sheesh!

Well, clear everything off your monitor the you are
displaying your graphics on. Create a graphics window, now
run your program. Your graphic window should still be
visible. ;-)
What? That seems onerous? Well, then I use the inexpensive
program Actual Title Buttons, especially when I am teaching
on a laptop, to add the ability to pin a graphics window
to the front, or to roll it up out of the way, when I want
to see something on the display.
It's the only way I know to overcome the problem with WSet
being broken.
Curiously, WSet occasionally works if you run a widget
program just before you type WSet. Don't ask me why.
It's one of the mysteries of the Universe. :-)

David

Hi David!
Actually.. I *am* using two monitors; and the plot window and IDLDE
are on different monitors! So how do I make that work? My coworker
who is the only other person who needs to uo use my code has two
monitors, as well... we can improvise :) I was trying to avoid
learning widgets for now (though I know it will have to happen,
eventually)

Use two monitors. Display your IDL plot windows on one
monitor and your IDLDE in the other. ;-)
Until WSet gets fixed (unlikely, since it has been
broken for so damn long!), there is no hope for this
on a single monitor system. The alternative, I guess,
is to write a widget program, rather than trying to
collect input from the command line.
