No, I got that part. My point was (or was supposed to be) that QComboBox 
can also display a tree directly, if you use it's setView method and set 
a tree view there. For easy use, you'd only need to confine the tree to 
a single column, but the parent/child relationship does not need to be 
removed for that.
