title: Setting a label's text depending on the item selected in a combobox (QT/C++)
body: <p>I'm new to QT creator and I was wondering if you could give me a hand with a little issue I have. 
  I have a combobox which I have items such as "completely new" and "amateur". I also have a label which I want a specific number to appear in the label depending on the item selected in the combobox. For example:
  Combobox("completely new") = label("11")
  I'm not entirely sure how I would code this. My attempt is below, but it's error riddled, apologies.</p>
  
  <pre><code>if(ui-&gt;comboBox-&gt;itemData(ui-&gt;comboBox-&gt;"Completely new"){
         ui-&gt;labelThreshold-&gt;setText("11");
     }
  </code></pre>
  
  <p>Any help would be greatly appreciated, cheers!</p>
