This is not PCManFM QT 1, it's PCManFM QT 0.1.0

PCMan seems to enjoy his new toy (previous link)
I, however, need to admit that working with Qt/C++ is much more pleasant and productive than messing with C/GObject/GTK+.
Since GTK+ 3 breaks backward compatibility a lot and it becomes more memory hungry and slower, I don’t see much advantage of GTK+ now. GTK+ 2 is lighter, but it’s no longer true for GTK+ 3. Ironically, fixing all of the broken compatibility is even harder than porting to Qt in some cases (PCManFM IMO is one of them).
