No matter what I try, I cannot modify the base font size from the programmed defaults. What is the proper way given:

Qt Code: 
  1. QTextDocument document;
  2. 		QString allText=QString("<html>"+appointmentSheet+"</html>")
  3. 			.arg("1")
  4. 			.arg("2")
  5. 			.arg("3")
  6. 			.arg("4");		
  7. 			//1
  8. 		document.setHtml(allText);
  9. 			//2
  10. 		document.print(&printer);
To copy to clipboard, switch view to plain text mode 

Calling setDefaultFont() at location #1 or #2 have no effect for me. I've also tried using a textedit and setFontPointSize(). I wish to provide the base font,a nd let the document modify it from there, as it uses relative sizing and other styles.
