Hi
Is it possible to detect volume up/down keys in QML on Symbian 3?
I've been trying to get any key press feedback in QML. But nothing happens, no key event is triggered at all.Keys.onPressed: { console.log("key has been pressed"); }Although, on Windows 7 the same QML code works as expected.

To answer your first question. No, hardware volume keys are not currently mapped to Qt::Key_volumeUp/Down.
If you don't get any feedback on any key presses you should file a bug for S^3.

I have the same issue on Symbian 3 (N8), and it seems even Qt C++ cannot receive key events for volume up/down! Can anyone explain why???

Okay, I did some search and found a bug report for this "Enable key capture and remcon interfaces for Qt apps on Symbian":http://bugreports.qt.nokia.com/browse/QTBUG-4415 , but this looks like left for more than a year and doesn't look promising.
Meanwhile, I did some more search and it seems only way is to use "Symbian Remote Control API":http://wiki.forum.nokia.com/index.php/TSS000432_-_Utilising_media_keys and somehow wrap it as QDeclarativeItem. I'm happy to share the code snippet if somebody is interested but not sure where's the proper place.

You could use the Symbian Remote Control API to catch keypress events in C++ and then send signals to QML.

I created a new wiki entry and put code there. "Getting Audio Volume Key Event on Symbian Devices":http://developer.qt.nokia.com/wiki/AudioVolumeKeyEventOnSymbian

That link seems to be no good. Try to upload again, and maybe put some text on the page too, please?

Try this link "Getting Audio Volume Key Event on Symbian Devices":http://developer.qt.nokia.com/wiki/Audio_Volume_Key_Event_On_Symbian , the next time use the search function of the Wiki.
