[Interest] Qt 5.6.1 widget app terminates if do not accept Android back key ?

[Eddie Sutton]

Has anyone seen this?

I cannot find any useful clues in adb.

The app terminates unless I add a keyReleaseEvent to accept the Key_Back.


#if defined(Q_OS_ANDROID)
///
///  Android back button kills TSR ?
///
/// Adding a keyReleaseEvent that accepts the event prevents the crash.
/// I do not understand reason why.
///
/// Ignoring the Android back button will annoy users but is better than crashing.
///
void MainWindow::keyReleaseEvent(QKeyEvent *event)
{
    if( Qt::Key_Back == event->key())
    {
        qDebug("Android Back button");
        event->setAccepted(true);
    }
}
#endif

Thanks in advance,

-Ed
