[Qt-qml] QML on latest N900 PR1.2 vs QML in 4.7

[Ivan De Marino]

Hello.

After investigating and banging my head against the screen, I need some
help. Possibly from a someone with his hands in QML as well as N900.

I have been working on this project of mobile browser, built using QML for
the UI.
And since the beginning been fighting with QML changing every now and then:
not blaming anyone, I actually understand that this technology is evolving
and I LOVE the way it's going. Every change makes it more coherent and
Qt-ish.

Problem is that I'm a bit stuck now: the latest version of my project works
without any problem (aside from the bugs I didn't discover yet :P), while on
N900 the behaviour is always a bit "flaky". With realease 2010-05-20 of the
packages of "libqt4-experimental" for N900 1.2, I now lost SCROLLING/PANNING
And I can't make my head around on what is the actual problem.
I just use a Flickable element with a WebView inside: don't see what can go
wrong, and only on N900.
The QML part of my project here:
http://github.com/OrangeLabsUK/OrangeMobileBrowser/tree/master/orangemobilebrowser-1.0/src/qmls/
 .

Plus, I can't use OpenGL in my GraphicsView because... no idea! It's slow,
painfully slow. I get much better performance if I "#ifdef" it out.
How I initialize the QGLWidget here:
http://github.com/OrangeLabsUK/OrangeMobileBrowser/blob/master/orangemobilebrowser-1.0/src/MainView.cpp
 .

<http://github.com/OrangeLabsUK/OrangeMobileBrowser/blob/master/orangemobilebrowser-1.0/src/MainView.cpp>Please,
take a look to the source code if you want to see what I do.
The stuff that is online is up-to-date.

Thanks in advance for any help.

PS Yes, I thought this might be a bug, but I want a second opinion before I
file it.
