How to use the keyListener

General JUCE discussion

i’m a bit confused by the keylistener.
i have my main component, a window. it contains a second component, a circle. i want my circle to “do” something, when a key is pressed.
so i made the main component a keyListener, and added the function

	bool keyPressed (const KeyPress &key, Component *originatingComponent)
	{
		myCircle->do();
		return 0;
	}

and added

myCircle->addKeyListener(this); in the constructor of my main component.
but this does not work.

but it does work, when i try it with mouselistener instead (and it’s corresponding button down function).
why is this so?

thanks!
