+Resolve the overloaded method to call.  The algorithm works conceptually like this:

+        of unknown type.  
+    2.  Filter the set of overloads to only contain those with the closest number of 
+        parameters.
+        For example, if we are called with 3 parameters and there are 2 overloads that
+        take 2 parameters and one that takes 3, eliminate the 2 parameter overloads.
+    3.  Find the best remaining overload based on its match score.  
+        If two or more overloads have the same match score, call the last one.  The match

     \i Before Qt 4.5, if you called showFullScreen() on the main window, the QToolbar would
         disappear since it is considered to be part of the title bar. Qt 4.5 and up will now work around this by pulling
         the toolbars out and back into the regular toolbar and vice versa when you swap out.
-        However, a good practice would be that turning off the unified toolbar before you call
-        showFullScreen() and restoring it after you call showNormal().
     \endlist
 
     Setting this back to false will remove these restrictions.
