So i downloaded MADDE for my laptop and installed it. Also installed MADDE client on the n900. So far so good. Next went on the maemo wiki to see what do i need to do to set up Qt Creator. I needed newer Qt Creator, version >= 1.3.80. Ok let’s do things for good. So i rolled my sleeves up and started writing PKGBUILDs. Two were needed to get latest qt and qtcreator from git and install them in /opt so they don’t conflict with distro provided ones (You can find them in aur – qt-opt-git and qtcreator-opt-git). Some things went very wrong so docs and qsqldrivers don’t seem to build or be detected(i think it’s a qt issue), but never mind qt creator starts, even if it was bragging about qt private headers…

Nice…

So i open up minerva project and set my n900 as target. I start building. All seems ok. Then BAM! i meet reality. I get error on packaging. PACKAGING? WTF? I didn’t want to package, just run my app! So i find out that madde in order to execute your *incomplete* app packages it, sends it to your device, installs it, runs it, then when you repeat it does the same steps again. That seems a fail to me.

The good thing about madde is that i got my binaries for my device, so with a couple of scp’s and wtf’s i got Minerva running on n900. Next goal -> migrate to cmake.

Minerva on N900

PS: I think i found a bug in maemo’s input. When writing in Minerva’s screen i get only caps, and shift doesn’t change case. That needs further investigation as i also experience such annoyance also in Fennec.

Ecco cosa offre di nuovo:
- Animation Framework. E’ fatto per quelli che adorano le EFL ( :) ) per le animazioni facili da fare. Dicono che è solo l’inizio. In effetti hanno ragione perché nel branch kinetic di qt ci sono cose moolto interessanti.
- State machine. Qua so ben poco, ma dicono che può essere usata come nelle EFL con i stati della gui e in generale dell’applicazione.
- Multi-touch. Come può mancare in un framework serio?
- Gestures. Questo è il motivo principale per cui svilupperemo (mandarancio e io) OpenDesk per le qt > 4.6. (Per altro a presto pacchetto qt-unstable in archmobile ;) )
- Accesso al DOM del QWebView. (Immaginatevi programmino-scavallo flickr)
- Qt3D. Hanno semplificato le API
- Multimedia Audio Services. Hanno fatto qualcosa a più basso livello di phonon
- Performance optimizations. Come sempre. Hanno riscritto QGraphicsView e hanno tolto support win 9x

Questo è solo quello che riguarda la tech preview di qt, ma in git ho pure trovato un sottoprogetto tutto dedicato ai telefonini. Include un framework per i contatti e altre cose che non ho guardato ancora.
