title: Tkinter: winfo_reqwith() returns wrong values
body: <p>I wrote a code which prints window's size after it gets resized, but every time the function prints "200" for width and "200" for height, no matter the window size is.
  How can i solve the problem?</p>
  
  <p>Here's the code:</p>
  
  <pre><code>from tkinter import *
  
  Root=Tk()
  Root.title("Window")
  
  lab = Label(Root, text = "Test")
  lab.pack()
  Root.geometry("300x300")
  
  RWidth=Root.winfo_reqwidth()
  RHeight=Root.winfo_reqheight()
  
  
  def check(event):
      print(RWidth)
      print(RHeight)
  
  Root.bind("&lt;Configure&gt;",check)
  
  
  mainloop()
  
  </code></pre>
  
  <p><strong><em>Solved!</em></strong></p>
