Native Development

Guys, I'd be happy to take part in the developing of bb10 components too. At this time I have some basic things done in pure QML, but it's just a temporary solution for my work project.

I think, most of the qt components for symbian ready to go on BB10 except screen sizes etc. Afaik, the screen sizes problem is soved already, but the solution is not available, unfortunately

Sorry, it seems I've misunderstood something. I'm working on components for Cascades look and feel for QtQuick. It's a little different thing so.

Alright, I was hoping to do some more coding over the weekend but unfortunately my DevAlpha stopped working on Friday evening I still hope it will power up again somehow, otherwise I have to see if RIM will exchange it for a working one...

Anyways, I've pushed my code changes to Gitorious so others can have a look at it as well. The branch is called "bb10" and can be found here:

https://qt.gitorious.org/~conny/qt-components/connys-qt-components

Changes are:

• Initial adaptation to hi-res screen of DevAlpha
• Initial code to support orientation changes (not really working yet)

Over all the code is still very hackish and rough but it might help others to get startet as well.

If you're using the default Qt libs on DevAlpha the performance will be really bad. Current Qt 4.8 (Git) contains a bug fix that inscreases performance. Still it's far from 60 FPS.

Have fun

Oh and something else: In your main function you probably want to do something like this, otherwise it's difficult to press buttons etc...

QApplication app(argc, argv);

// Because of the hi-res BB10 display be need a higher tolerance to mouse movements
app.setStartDragDistance(16);

ported my app to bb10. piece of cake thats about good news

bad news: Flickable is laaaaagggy

[connyhald]

Great news

About the lag: Did you try with recent Qt from Git? It's much less laggy compared to the default BB10 Qt.

thanks

Sure Here it is: http://qt-project.org/wiki/QNX

Let me know if you have specific issues.

first of all, -qpa not supported on win: https://bugreports.qt-project.org/browse/QTBUG-20819

second, mkspec for bb10 is not visible for windows configure tool

it seems, win configuration tool doesnt supprts qnx at all
