title: gtk+ checkbutton settings
body: <p>Is there a way to use <code>set_active</code> on a gtkCheckButton but without the user being able to press/toggle the said button?</p>
  
  <p>In other words, I want to programmatically control the <code>active state</code> of the CheckButton but I don't want the user to be able to change it.</p>
