Alas, this "solution" appears to only work on my
Windows machine. WSHOW is completely ignored on my
LINUX machine, where I have been completely unsuccessful
in getting an IDL direct graphics window to pop forward
on the display.
Cheers,

Alright. Are you ready for this? Please sit down.
It turns out this probably has nothing to do with
prayer. (I know, I'm disappointed, too.)
Here are the details. Windows 7 64-bit OS, with this
IDL version:
{ x86_64 Win32 Windows Microsoft Windows 8.0 Jun 17 2010 64 64}
If I open a graphics window with the Window command, that
window will never come to the foreground with the WSHOW
command.
UNLESS, I then open a widget window. Here is the code
I use to open a widget window (I can use any widget
program I have hanging around, but I wanted to reduce
the problem to its essentials.)
;*******************************************************
PRO junk
tlb = Widget_base()
draw = Widget_Draw(tlb, xsize=200, ysize=200)
widget_control, tlb, /realize
xmanager, 'tlb', tlb, /No_block
END
;*******************************************************
Now the first IDL graphics window will come forward
on the display with WSHOW. I can kill the widget window
and the graphics window will *still* come forward. If
I kill the display window and open another one, I have
the same problem: WSHOW doesn't work again. Opening a
widget window mysterious wakes it up!
If I have multiple IDL graphics windows on the display,
they ALL ignore the WSHOW command. Until I run "junk".
Then they all respond normally to WSHOW.
If I run this sequence:
IDL> window, 0
IDL> junk
IDL> window, 1
Then neither window 0 or window 1 will respond to the
WSHOW command!!
Extremely weird. Now I'm worried about demons... :-(
Cheers,
David

Well, I'm still in this session. I'm just working the
way I normally do. Now WShow works sporadically. I have
not been able to discover what conditions, if any,
cause it to work, and which don't. It's about as
reliable as the dog.
I feel my faith ebbing and flowing. Do you
suppose I'm not praying hard enough? Back to
the rosary, I guess. :-(
Cheers,
David

I have this problem too.
The following code would not produce anything on my screen neither:
IDL> print, !VERSION
{ x86_64 linux unix linux 7.1.1 Aug 21 2009 64 64}
IDL> cgDisplay, /FREE, XSIZE=500, YSIZE=500, /PIXMAP
IDL> cgplot, LOADDATA(17)
IDL> xwin = !D.WINDOW
IDL> help, xwin
XWIN LONG = 44
IDL> wshow, xwin
So what are the alternatives? Currently I am doing this:
IDL> img = Transpose(tvrd(/TRUE), [1,2,0])
IDL> WDELETE, xwin
IDL> cgDisplay, /FREE, XSIZE=500, YSIZE=500
IDL> cgImage, img
But is there a better solution ?
Thanks a lot!
