C++ Gurus

Sorry, if I wasn't clear. I made two suggestions to solve your problem and the longer i think about the first one the less I like my own solution. Because it would work in another way than the standard library and thus may confuse readers of your code.

I as an user of your binary heap would expect that the implementations calls operator<(T, T) for all possible T in the same way.

Peppe, your right. I mixed up things from what I looked up in the sources some times ago. The layout only keeps book of the widgets it manages, but does not take ownership.

But what's really important for the users: After the UI is set up, all parent-child relationships are correct. I really do like Qt :-)

Wooh!
