title: Positioning a textbox on tkinter
body: <p>I'm new to tkinter and it'll be a while till I get used to it. At the moment I'm trying to move a textbox around just to see how it works, but I can't really get it to move from the center. Tried using grid and it didn't move at all. Tried using pad x &amp; y and it did move but in some places disappears. My goal is to make a simple log in screen. </p>
  
  <p>This is what I got:  </p>
  
  <pre><code>from tkinter import *
  
  import tkinter.messagebox
  
      #def logVali():
  
  
  form = Tk()
  
  form.title("Log in screen")
  
  form.geometry("700x200+300+200")
  
  txtVar = StringVar(None)
  
  usrIn = Entry(form, textvariable = txtVar, width = 50)
  
  usrIn.grid(row = 30, column = 40)
  
  usrIn.pack()
  
  form.mainloop()
  </code></pre>
  
  <p>Any suggestions? Thanks</p>
