Every single one of those files was written by someone other than myself.  
Generally, you copy the style of the file you're modifying.

Obvious commenting gets in the way of the code.  // 

If you cared about an API reference manual, you'd use one of the standard 
tools for it, instead of coming up with your own function comment style like 
you have.

Doesn't seem that way to me -- 

QLabel *addLabel(QString caption);
QLabel *addLabel(QString caption, LabelSize size);

instead of:

QLabel *addLabel(QString caption, LabelSize = Medium);

No if statements required.  Same situation with ShowPopup().

Regardless, a very short if statement in a function is better than an entirely 
new function when they're doing the same thing.  If they're doing different 
things, they shouldn't be overloaded in the first place.  I prefer to leave 
function overloading to deal with different types.

New patch looks better, though, I'll see about getting it merged in later 
tonight.
