title: python pack() and grid() methods together
body: <p>Im new to python so please forgive my Noob-ness. Im trying to create a status bar at the bottom of my app window, but it seems every time I use the pack() and grid() methods together in the same file, the main app window doesn't open. When I comment out the line that says statusbar.pack(side = BOTTOM, fill = X) my app window opens up fine but if I leave it in it doesn't, and also if I comment out any lines that use the grid method the window opens with the status bar. It seems like I can only use either pack() or grid() but not both. I know I should be able to use both methods. Any suggestions? Here's the code:</p>
  
  <pre><code>from Tkinter import *
  import tkMessageBox
  
  def Quit():
   answer = tkMessageBox.askokcancel('Quit', 'Are you sure?')
   if answer:
      app.destroy()
  
  app = Tk()
  app.geometry('700x500+400+200')
  app.title('Title')
  
  label_1 = Label(text = "Enter number")
  label_1.grid(row = 0, column = 0)
  text_box1 = DoubleVar() 
  input1 = Entry(app, textvariable = text_box1)
  input1.grid(row = 0, column = 2)
  
  statusbar = Label(app, text = "", bd = 1, relief = SUNKEN, anchor = W)
  statusbar.pack(side = BOTTOM, fill = X)
  
  startButton = Button(app, text = "Start", command = StoreValues).grid(row = 9, column = 2,  padx = 15, pady = 15)
  
  app.mainloop() 
  </code></pre>
  
  <p>Any help is appreciated! Thanks!</p>
