Obviously, because Fremantle isn't shipping official Qt support.

Nokia is porting Qt, the results of which are available right now in Extras. But for Fremantle Qt will only be community supported, the official support will come with Harmattan. This means a Qt Garage project and distribution through Extras (much like Python).

Unfinished how, exactly? Are you referring to the example Clutter UIs available or the actual toolkit? Either way, recall that this is only a pre-alpha.

I didn't make a differentiation because it isn't relevant here. They've got somewhere in the ballpark of 6 months to polish it up and move it to Extras. Give it time.

Setting up Extras for Fremantle means setting up the autobuilder for Fremantle, which isn't just a "flip the switch" sort of task. Especially given that this pre-alpha isn't targeting application developers or users, it may take a few weeks to get Extras set up.

Again, these things take time. This is a very early pre-alpha release intended to give platform developers and those folks interested in the platform architecture a jumpstart on Fremantle, and for Nokia to begin collecting feedback about it from them. This release is not intended for application developers, nor is it intended for users. From your questions, it sounds like you're more of an application developer, so you're gonna want to wait for a later alpha release or the beta release around March-May.

This is not a finalized 1.0 release ready for general consumption, so don't expect everything that will be in the final product to be here yet, and don't expect everything that is here to be 100% polished.

If you want to get started with Qt right now, my recommendation is to start with the Qt page on Garage and go from there.
