With two monitors attached to the computer, the `winfo' and `wm'
commands adds the area of both monitors as if they were just
one. Procedures for maximizing the size of a toplevel, like this

proc maximize toplevel {
pack propagate $toplevel 0
update idletasks
wm geometry $toplevel +0+0
wm minsize $toplevel [lindex [wm maxsize $toplevel] 0] \
[lindex [wm maxsize $toplevel] 1]
}

makes the toplevel cover both screens.

Is it possible to query the size of just one monitor?

I'm not experienced with multiple-head setups on Linux, so if there is a
setting that makes possible to detach the monitors so they no longer are
considered a single one, that could be okay too.

I have no experience on multihead on Linux neither!

Stupid guesses by me:
- winfo screenwidth $toplevel
- winfo screenheight $toplevel
- winfo winfo vrootheight $toplevel
- winfo winfo vrootwidth $toplevel

- wm state $toplevel zoomed;winfo width $toplevel;winfo height
$toplevel

Hope this helps,
Harald

All of them return the combined size of both monitors.

`zoomed' is a Windows thing. The rest is not useful either because we
need the area of the monitor, not the area of the toplevel.

Thanks for trying. At this stage I appreciate any kind of help, even
blind guesses.

Just discovered that gitk maximizes correctly. I'll look into its source
code with my fingers crossing hoping it doesn't use a binary extension
for that.

Try this:

wm attributes . -zoomed 1

Thanks, but I'm using 8.4 and -zoomed was introduced in 8.5.

Yes, I plan to upgrade to 8.6.x (x > 1) once it is out :-)
