title: Change colour of a button's text in Haskell (GTK)
body: <p>How do I change the colour of a button's text in Haskell (GTK)?</p>
  
  <p>The code that I am using at the moment is:</p>
  
  <pre><code>button &lt;- xmlGetWidget xml castToButton "buttonLabel"
  </code></pre>
  
  <p>Should I change the colour from within the program code, or I could do it in the XML as well?</p>
