How to handle "Unhandled key code"

Oleg R.

Hello,

I'm developing software for PDA running Android. PDA has a few keys that I would like to handle in QML. While pressing the key I'm getting error in console: "Unhandled key code 294".

How can I handle unknown keys?

I do have eventFilter, but the message still shows up.

@Oleg-R
my guess is that this message comes from a 3rd party code/element you are using in your code?

It might be from the android QPA plugin.
https://code.woboq.org/qt5/qtbase/src/plugins/platforms/android/androidjniinput.cpp.html#763

In namespace QtAndroidInput,

static int mapAndroidKey(int key)
    {
     ...
     switch (key) {
     ...
            case 0x000000de: // KEYCODE_MEDIA_AUDIO_TRACK
                return Qt::Key_AudioCycleTrack;

            default:
                qWarning() << "Unhandled key code " << key << '!';
                return 0;

Receiving the key press may require using a native event filter.
