Apart from the fact that Dick has pointed out that this window info is
already in 6.3,
I'll pass on the babe magnet T-Shirt - I've already got 3 babes living
under my roof,
4 if you include Lucy the Whippet, and I get out-voted enough as it is.

Crikey! I pestered RSI/IITVIS to make this info available - but I
didn't know they'd
actually done it!
Way better than my kludge... ;-)

In IDL 6.3, multiple monitor support was added, along with an option for
excluding taskbar size on Windows. I wrote this function to get at the
desired info easily:
;; Handy function for getting screen size of primary monitor, optionally
;; excluding the taskbar
;;
;; Example:
;; freeSize = GetPrimaryScreenSize(/Exclude_Taskbar)
;; Print, freeSize
;; 1280 946
FUNCTION GetPrimaryScreenSize, Exclude_Taskbar=exclude_Taskbar
oMonInfo = Obj_New('IDLsysMonitorInfo')
rects = oMonInfo -> GetRectangles(Exclude_Taskbar=exclude_Taskbar)
pmi = oMonInfo -> GetPrimaryMonitorIndex()
Obj_Destroy, oMonInfo
Return, rects[[2, 3], pmi] ; w & h of primary monitor avbl. space
END

Alright, it's the Cool Special Kludge, written
after a long day filled with too many prawns on the barbie
(not to mention too many beers!), but I have to admit
it *does* work. :-)
And--a very nice feature for something this elegant--it
*also* keeps track of whether the user is auto-hiding the
task bar or not.
Cheers,
David
P.S. I hope you are passing the secret to this along to the
good folks at ITTVIS, Andrew. They could use something like this.
Hold out for the big bucks, though. Or, at the very lease, their
babe magnet of a T-Shirt. :-)

In my testing here, I find that Andrew's WINDOW_SIZE function
reports a window size of 1272 by 969 on my 1280 by 1024 display.
This accounts for the taskbar AND window decoration for the TLB,
including the window title bar.
Dick's GetPrimaryScreenSize reports 1280 by 996, which does NOT
include any window decoration (including the window title bar).
Moreover, the /EXCLUDE_TASKBAR keyword only works if the taskbar
property "keep taskbar on top of other windows" is set. If this
property is not set, then the entire window size is returned.
This is identical to what is returned in Get_Window_Size(). That
is to say, not as useful as it could be.
Bottom line, although Andrew's solution is a bit of a kludge, it
does seem to return more useful information if you have the
practical purpose of building a widget program in mind.
Cheers,
David

Just for fun, I'll quote the original request:
lory writes:
> How can I find the "free" screen size ? I mean the size of the area
> available to display GUIs, something like the dimensions returned by
> GET_SCREEN_SIZE but subtracting the area dedicated to the task bar, if
> it is displayed.
I don't see any mention of how *many* windows lory might want to put on the
screen, so I think I covered the request with the routine above. I think
that if the taskbar can be covered up by our window, then it's reasonable to
report full screen size as being available. I do have one quibble with
oMonInfo -> GetRectangles(), that if I have "Auto-hide the taskbar" set, the
two rows of pixels which are *not* available to an IDL window are being
counted as available.
Now, if you want to know about setting up windows on the screen precisely,
this is what I use. TLBWindowDressing returns the width of the frame and
title bar (actually the XY offset of the first widget you would add to a
base) for a window with any TLB_Frame_Attr you wish to pass it. The size
available to widgets inside a single window that will fill the screen can be
found as follows:
scrSize = getprimaryscreensize()
wd=tlbwindowdressing()
xAvbl = scrSize[0] - 2*wd.frameWidth
yAvbl = scrSize[1] - wd.yoffset+wd.frameWidth
tlb=widget_base(space=0,xpad=0,ypad=0,/row)
wdraw=widget_draw(tlb,xsize=xAvbl,ysize=yAvbl)
And if you need to lay out several windows to fill the screen, you can use
these numbers to figure that out, too.
