title: Empty Tkinter Window
body: <p>I am doing a bit of basic Tkinter code, and when I launch I get no errors, but my window is empty, even though I have added things to them. I saw <a href="https://stackoverflow.com/questions/23233424/python-tkinter-empty-window">this</a> question here, but that does not help me, as I have what it says to do.</p>
  
  <pre><code>from tkinter import *
  
  class App:
  
  def __init__(self,master):
  
      frame = Frame(master)
      frame.pack
  
      self.sg = Button(frame, text = "Study Guide", command = self.studyGuide)
      self.sg.grid(row = 2, column = 1)
      self.sg.pack()
  
      self.quizlet = Button(frame, text = "Quizlet", command = self.quizlet)
      self.quizlet.grid(row = 2, column = 2)
      self.quizlet.pack()
  
      self.flashcard = Button(frame, text = "Flash Cards", command = self.flashcard)
      self.flashcard.grid(row = 2, column = 3)
      self.flashcard.pack()
  
      self.quitButton = Button(frame, text = "Quit", command = frame.quit)
      self.quitButton.grid(row = 3, column = 2)
      self.quitButton.pack()
  
      self.text = Label(frame, text = "Social Studies Study Tool")
      self.text.grid(row = 1, column = 2)
      self.text.pack()
  
  def studyGuide(self):
      print("Study Guide")
  
  def quizlet(self):
      print("Quizlet")
  
  def flashcard(self):
      print("Flashcards")
  
  root = Tk()
  app = App(root)
  root.mainloop()
  </code></pre>
