title: What winapi functions does QT use to display text?
body: <p>I'm interested in WinApi functions that QT uses to display text (on buttons, etc.)</p>
  
  <p>Any input will be appreaciated.</p>
  
  <p>Edit:
  I'm interested in the particular functions which are used, that is, their names. Let's say we have a QLabel with text set, now, what gdi/user32 function will be called in the end to get the text out.</p>
