title: how to make the bar long as much as the main windows
body: <h2>I wrote this piece code:</h2>
  
  <pre><code>from Tkinter import *
  import ttk
  
  app = Tk()
  app.title('Myapp')
  app.geometry('200x150+50+50')
  
  labelText =StringVar()
  labelText.set('Insert the version you want to check')
  label1 = Label(app, textvar=labelText, height=2)
  label1.pack()
  
  stringadacercare = StringVar(None)
  lastringa = Entry(app, textvar=stringadacercare)
  lastringa.pack(side='left',padx=5,pady=30)
  
  progressbar = ttk.Progressbar(orient=HORIZONTAL, length=200, mode='determinate')
  progressbar.pack(side="bottom")
  progressbar.start()
  
  app.mainloop()
  </code></pre>

  <p>What I've been trying to do was the progress bar long as much as the main windows, however
  it doesn't work with the textbox.</p>
  
  <p>How can make it work? Is there another way to create a text box that is also easier to move?</p>
