How do I toggle caps lock on keyboard?

Message 1 in thread

Hi All.

Without resorting platform dependent API, is there a way to toggle the 
caps lock on the keyboard with QT? Would prefer if it works on Windows 
and Linux.

My code below does not work. Have I done something wrong?

QCoreApplication::postEvent( ptrToApp,
   new QKeyEvent( QEvent::KeyPress, Qt::Key_CapsLock, Qt::NoModifier ) );	

Thanks you.
Jason.

Events are posted in response to hardware key presses. You can also post 
"fake" events. However posting events will not change the state of teh 
hardware.
