What events can the next piece of code handle?

public class CustonLomponent extends Componentimplements

Component.DrawTask,Component.EstimateSizeListener,Component.TouchEventListener

{

......

public CustomComponent (Context context){

...

Set up a TouchEvent to respond to events

setlouchEventListener(this);

}

...

@Override

public boolean onTouchEvent(Component

component,TouchEvent touchEvent){

switch (touchEven

Neither event can be processed

can only handle DOWN events

Only UP events can be processed
