With LinuxCNC 2.7.4 (Debian Wheezy), the above maximize code was an improvement, but didn't fully maximize the Axis screen, which was shifted down and to the right.
I had better luck with the following, where tb_h is the height of the window manager's toolbar. But this also didn't actually maximize Axis like the maximize button does.
Code:
tb_h = 32
root = root_window
w, h = root.winfo_screenwidth(), root.winfo_screenheight() - tb_h*2.5
root.geometry("%dx%d+%d+%d" % (w, h, 0, tb_h))
The following seems to work well. It makes Axis fullscreen, which also hides the window manager's toolbar (less distraction and more space for Axis). While this may prevent getting back to the toolbar without closing axis, if a terminal is left open, and sessions are saved, alt-tab will get you back. There's probably some other shortcut as well.
Code:
root_window.attributes('-fullscreen', True)
Full disclaimer: I know nothing about Tk... this is just what seemed to work well for me. Hope others find it useful.
