overriding example application function (events for keys)

I'm writing a physx example application,
I've based it on the "CameraTrack" sample.

This one uses the "Demo Example application".

I have some keyboard shortcuts that I need.

Let's say pressing P does something.

Obviously I won't add it to the "example application", I want the code
for this to be in my project.

protected virtual void HandleInput(FrameEvent evt)
{
//here's the example application stuff
}

I need to override this and put my code in my application..
How do I do this?..

protected override void HandleInput(FrameEvent evt)
{
base.HandleInput(evt);
if (this.inputKeyboard.IsKeyDown(KeyCode.KC_P) && (this.toggleDelay < 0f))
{
// do stuff
this.toggleDelay = 1;
}
}
Or subscribe to the inputKeyboard.KeyPressed event.

thank you for the reply,
when I enter the code you posted, still nothing happens.
is there a chance that I could have missed something basic here?..

is there a chance you could help with the second example you mention too?

Or subscribe to the inputKeyboard.KeyPressed event.

public override bool UseBufferedInput
{
get { return true; }
}
public override void CreateInput()
{
base.CreateInput();
this.inputKeyboard.KeyPressed += new KeyListener.KeyPressedHandler(inputKeyboard_KeyPressed);
}
bool inputKeyboard_KeyPressed(KeyEvent arg)
{
if (arg.key == KeyCode.KC_P)
{
//do stuff
}

return true;
}
Both work for me in the otherwise unchanged CameraTrack sample.

after some trail and error I got the first example to work.
Thank you very much, this helped me a lot today.
