How to auto-format the QLabel text
<p>I would like the text to auto-fit inside of the label. 
As the width of the QLabel gets more narrow the text formats to occupy multiple lines. Essentially I am looking for a way to format it the same way a html text is formatted when we resize the web browser window.</p>

<pre><code>label=QtGui.QLabel()  

text = "Somewhere over the rainbow Way up high And the dreams that you dreamed of Once in a lullaby"    

label.setText(text)
label.show()
</code></pre>
