Subject: TK: Get the "usable" screensize"?


Hi,

how can I get the "usable" screensize in Ruby/TK?
I mean, the total screensize minus taskbar (on Windows).

I tried:

  require 'tk'
  root = TkRoot.new
  root.state('zoomed')
  Tk.update
  p TkWinfo.x(root)
  p TkWinfo.y(root)
  p TkWinfo.width(root)
  p TkWinfo.height(root)
  p TkWinfo.geometry(root)

but this gives me only
  total_screensize - (taskbar + window_decoration)

window_decoration is titlebar and borders of a window, maybe
even something else.

I found  http://wiki.tcl.tk/11291  which points into the
same direction, but I cannot use it with success (it's TCL).

I'm using:
* Windows XP
* ruby 1.8.7 (2009-06-12 patchlevel 174) [i386-mingw32]
* TCL/TK 8.5

Thank you,
Axel
