Interface ClickListener

Every Screen interested in click events must implement this interface (Except when DELEGATE mode is used). Click event listener must be activated in Engine :

// Not interested in clicked sprites
engine.enableMouseControl(); // Equivalent to engine.enableMouseControl(MouseEventType.BASIC);

It's possible to capture the list of sprites clicked by setting the optional argument to true

// Capture sprites
engine.enableMouseControl(MouseEventType.SPRITES);

Sprites may also manage their behaviour themselves

// Capture sprites
engine.enableMouseControl(MouseEventType.DELEGATE);

When MouseEventType.DELEGATE is used, Screen needn't implement ClickListener interface To enforce declaration of interface, use MouseEventType.DELEGATE_STRICT. Screen declaration of onClick is called BEFORE any sprite, can cancel delegation by returning false.
