QML on N900 in RDA shows just black or white screen

[Gride79]

Hi,

I'm trying to test my QML+Qt application on N900s in RDA but the QML content is shown just in black, or when in fullscreen, sometimes in white. I've tried also simplest QML samples from Qt Creator and the result is same. Same deb-file in real N900 works fine, and same code on RDA's Symbian devices runs fine.

Any advices on this?

I found out the reason. I had installed Madde 2.2 on my N900 which also installed QtQuick 1.0 hotfix from extras-devel. This allowed to have "import QtQuick 1.0" in qml files, but in vanilla N900 it is not accepted, instead one should just use "import Qt 4.7". Therefore it was running in my N900 ok and failed in RDA.

Btw, why it is not possible to reboot N900 in RDA, or at least have button for task switching where one could kill app? Ctrl+backspace doesn't seem to work at least when using Mac with RDA like it does on real N900. Now if fullscreen app jams like it did with my app the device is in state that nothing can be done anymore.

unlike for mostly all Symbian phones, rebooting is disabled for N900, as based on experience the device did not automatically reconnect surely enough after a reboot (but may go "permanently" offline. this was a big issue especially with earlier firmware versions, the current firmware is somewhat better in this sense). I will need to check the task switcher button, should be possible to add a button like that to the device skin in RDA if it's currently missing.
