title: How to prevent Tkinter labelframe size changes when an empty label is inserted
body: <p>I create a LabelFrame widget. It has a nice size in the beginning:</p>
  <pre><code>import Tkinter
  form = Tkinter.Tk()
  
  errorArea = Tkinter.LabelFrame(form, text=&quot; Errors &quot;, width=250, height=80)
  errorArea.grid(row=2, column=0, columnspan=2, sticky=&quot;E&quot;, \
               padx=5, pady=0, ipadx=0, ipady=0)
  </code></pre>
  <p><img src="https://i.stack.imgur.com/RlyHh.jpg" alt="enter image description here" /></p>
  <p>But when I insert an empty string in it, the <code>errorArea</code> widget's size adjusts according to the inserted string:</p>
  <pre><code>errorMessage = Tkinter.Label(errorArea, text=&quot;&quot;)
  errorMessage.grid(row=0, column=0, padx=5, pady=2, sticky='W')
  </code></pre>
  <p><img src="https://i.stack.imgur.com/sWPXK.jpg" alt="enter image description here" /></p>
  <p>How do I give the <code>errorArea</code> widget a fixed size, so that its size won't change according to Lable inserted in it?</p>
