title: Python guizero: textBox = [textBox]
body: <p>OK, I been using guizero for a couple of days but I found a problem that has been perplexing me. Here a simplified version of the code.</p>
  <pre><code>from guizero import App, Text, PushButton, Picture, Drawing, TextBox
  
  app = App(&quot;Testing&quot;)
            
  def test():
      global testing
      print(testing)
  
  button = PushButton(app,test, text = &quot;press to test&quot;)
  button.bg = &quot;red&quot;
  button.text_size= 35
  
  tittle = Text(app, &quot;Testing input here&quot;)
  testing = TextBox(app, text= &quot;&quot; )
  app.display()
  </code></pre>
  <p>No matter what the users input into the Textbox, it is always print:</p>
  <p><em>[TextBox] object with text &quot;&quot;</em></p>
  <p>I tried putting testing into an argument in the function test, it comes up with the same thing.</p>
  <p><em>[TextBox] object with text &quot;&quot;</em></p>
  <p>If I don't make an argument in the function or global testing, it makes the same thing, and if I make the textbox before the button, I have the same problem.</p>
  <p>Can anyone find a way to work around the problem or to fix this, I'm new to guizero so I have little to an idea what I'm doing</p>
