Setting a Frame Size and Location in Tkinter

Question

I am trying to set a frame-size and the location of the frame (master widget) in Tkinter. Based off of this answer, I added this to my code:

from Tkinter import *
import ctypes
user = ctypes.windll.user32
screensize = (user.GetSystemMetrics(0), user.GetSystemMetrics(1), user.GetSystemMetrics(2), user.GetSystemMetrics(3))

class GetWord:
    def __init__(self, master):
        master.geometry("%s+%s+%s+%s" % (screensize[0], screensize[1], screensize[2], screensize[3]))
        # I added the above in, but not sure how it works
        self.frame = Frame(master, width = screensize[0], height = screensize[1])
        self.frame.grid()

However, when doing this I get a TclError:

Traceback (most recent call last):
  File #file path, line 39, in <module>
    f = GetWord(root)
  File #file path, line 8, in __init__
    master.geometry("%s+%s+%s+%s" % (screensize[0], screensize[1], screensize[2], screensize[3]))
  File "C:\Python2.7.3\lib\lib-tk\Tkinter.py", line 1534, in wm_geometry
    return self.tk.call('wm', 'geometry', self._w, newGeometry)
TclError: bad geometry specifier "1366+768+17+17"

I call the class like this:

root = Tk(className='derp')
root.columnconfigure(0, weight=1)
root.rowconfigure(0, weight=1)
f = GetWord(root)
root.mainloop()

How can I fix this? I want to have the frame start off in the center of the screen and start at a specific window size (right now it's full-screen but I will change that later on). Thanks!

Should be `"%sx%s+%s+%s"` for width, height, left, right (note `x` instead of `+`) — Anton Kovalenko, Feb 17 '13 at 15:55
@AntonKovalenko Oh, small mistake. You should add that as an answer. Also, how can I center the frame? — Rushy Panchal, Feb 17 '13 at 15:58
You are already filling up the user's whole screen with the frame, I don't see a need to center it then. — Siddharth Gupta, Feb 17 '13 at 16:02
@Siddharth I was just using the full-screen as an example. In my actual program, it will be about `w/4` and `h/4`. — Rushy Panchal, Feb 17 '13 at 16:24

You Need to use the letter "x" instead of "+"

master.geometry("%sx%sx%sx%s" % (screensize[0], screensize[1], screensize[2], screensize[3]))

I'm generally going to use `screensize[0]/2` and `screensize[1]/2` as the parameters. How can I center the window in the middle of the screen? – Rushy Panchal Feb 17 '13 at 16:01
