title: How to get the size (height) of a label after the word wrap
body: <p>First of all, I'm sorry because I don't have any code examples to provide (it's quite complex to narrow it down).</p>
  
  <p>Essentially, I have QLabel and I'd like to access the height of the label after the word wrap has been applied. </p>
  
  <p>It seems that it always return me the default value (640x480) instead of the actually height it needs (427 pixels).</p>
  
  <p>It's weird because, without .setWordWrap, I get the correct value (16449 x 13).  </p>
  
  <p>Any ideas?</p>
