this seems like a huge undertaking for a relatively small gain.

the lowest quality names are the very short abbreviations (i.e. only one 
or two letters).

these are usually based on the type of the argument. so QEvent maps to 
"e" or "ev", QWidget to "w", QSize to "s" or "sz", etc. then again, in 
many other places qt will use an unabbreviated type-name such as 
"event", "widget" or "size".

the overall quality and consistency of the names could be improved a lot 
by expanding these short abbreviations (assuming, of course, that the 
frequency of name clashes is very low).

a rough search for QWidget arguments in the qt-4.5.2 source found about 
450 cases, with 180 using the name "widget" and 110 using the name "w". 
so expanding "w" to "widget" could improve about 25% of the names.
