Called to indicate that a key has been pressed.
If your implementation returns true, then the key event is considered to have been consumed, and will not be passed on to any other components. If it returns false, then the key will be passed to other components that might want to use it.

Called when any key is pressed or released.
When this is called, classes that might be interested in the state of one or more keys can use KeyPress::isKeyCurrentlyDown() to check whether their key has changed.
If your implementation returns true, then the key event is considered to have been consumed, and will not be passed on to any other components. If it returns false, then the key will be passed to other components that might want to use it.
| originatingComponent | the component that received the key event |
| isKeyDown | true if a key is being pressed, false if one is being released |
