Here is a list of changes in Qt from 0.91 to 0.92.  Also look out+
−
for a few new classes; QPrinter, QFileDialog, QDir and QFileInfo.+
−
+
−
+
−
QApplication:+
−
-------------+
−
  Use setMainWidget( x ), not exec( x ).+
−
+
−
QString:+
−

QPainter:+
−
---------+
−
  pen(), brush() and font() no longer returns references.+
−
  You cannot do this any longer:+
−
	QPainter p;+
−
	...+
−
        p.pen().setColor( red );+
−
	p.brush().setStyle( NoBrush );+
−
  Instead, set a new pen or brush:+
−
	p.setPen( red );+
−
	p.setBrush( NoBrush );+
−
  This enables us to do better optimization, particularly for complex+
−
  programs.+
