ah, so you're going to add a QObject operator then? (because i don't see one 
there now, and when i tested a minute ago i just get the pointer address)

and when i said "is a rather useful feature" i also meant printing out the 
geometry. =)

unless wanted/needed.

true enough; there are methods in QtCore like that actually ...

depends on how much i get to work on it this month. i'd probably need to spend 
a day just bringing it up to where trunk/ is due to the amount of work that 
has gone on in kdecore in the last month or two... but it's substantially 
complete at this point.

i'd love them to. =)
