Native Development

Ok, I don't know about that. Only did the builing on Linux so far.

hi again

can you help me to understand whot I did wrong:

1. built qt 4.8.2 under linux

2. setup qtdir to the built Qt

3. built qt-components

but when I deploy all the stuff and try to run my app, got:

plugin cannot be loaded for module "com.nokia.symbian": The plugin '/apps/org.demo.MoneyAssistant.testDev_eyAssistant9e41277f/native/imports/com/nokia/symbian.1.1/libsymbianplugin_1_1_3.so' uses incompatible Qt library. Expected build key "arm blackberry g++ no-pkg-config", got "arm blackberry qcc no-pkg-config"

what is wrong?

thanks

ok, fixed the build issue but...scrolling speed become much much worse than with 4.8.0 libraries

Hi folks,

I ported the symbian components along time ago and uploaded them HERE. IIRC I had to change one of the components files to enable full screen for pageview on the pb, I cant remember where I had to make the changes but I can figure it out again if anybody is having trouble...

I also compiled the Qt 4.8.2 libs in x86 and armv7le debug and release, they were posted HERE  by Borceg.

With the latest 4.8.2 libs the scrolling in qml is smooth as can be for me (on pb), even on large detailed listviews. Also QDescktop services works out of the box for native email and browser access on my pb.

The original 4.8 libs that come with the bb Qt SDK should not be used, they are very buggy and way outdated!

To see all the bug fixes related to QNX/BB on the main Qt 4.8.2 branch look HERE

Have fun!

Cheers,

Jon

Hi jheron

You mention that QdesktopServices works out of the box for your PB for native email and browser.

I tried that and is not working on my, this

QDesktopServices::openUrl(QUrl("http://www.google.com",QUrl::TolerantMode));

 gives me:

"QDesktopServices::launchWebBrowser not implemented"

Can you confirm that opening url in native web browser works?

[jheron]

Apologies!

I should have said that qml desktop services works. I have not tried it from c++ yet. I ASSumed it would work on the c++ side too....

Here is what's confirmed to work from qml to open the native browser:

 Qt.openUrlExternally("http://website.com")

Cheers,

Jon

Hi Jon

just checked your bild of 4.8.2. Unfortunately I have same issue as with my own build: GridView flicking is an slideshow

[jheron]

Is that on a playbook or a bb10 sim that its lagging?

I have only released my apps for the playbook and have not done any in depth testing on the bb10 sim. They were very glitchy at first but once 4.8.1 came out they smoothed right out like silk on my pb... Perhaps its an issue with bb10 if that's what your testing with?

Perhaps logging a bug will get it some attention if that is the case. Or perhaps a new build with the latest bb10ndk released today will make a difference...

Good luck!

Jon

I've tested it on Alpha device

Sorry guys, I was away for a while... Of course the definition of "laggy" is a bit fuzzy, but for me the difference between the default BB10 Qt and a recent Qt 4.8.2 was huge. To me it's still not butter-smooth but somewhat ok.

If anyone is interessted I could upload my binaries of Qt and Symbian Components somewhere so you could check it out by yourself.
