I am not familiar with Qt, but it looks to me like svdwal has a good point. From what I can figure out Qt appears to go down the road of the Hildon add-on to Gtk+, where in many places the original Gtk call was simply replaced with an equivalent Hildon call. The right thing would have been to leave as much as possible in place, and just provide library versions where the standard Gtk calls were modified to do the Hildon thing.

Instead, to create a multi-system (desktop+Hildon) application you had to sprinkle the code with #ifdef and the like. Obviously the application itself will always have to be small-display compatible, but in addition to that the Hildon version of Gtk+ added (in my opinion) unnecessary replacement functions for standard stuff.

So, instead of the special-for-Maemo-6 Qt functions, wouldn't it be possible to massage the underlying objects/functions, to minimise the boiler plate code changes?
