Two things which will help me and others help you : ).

1)  can you say a bit more about the way in which it does not work?  what is the behavior that you are expecting and how does what is currently happening differ?

2)  can you post the rest of your code?  or, if there isn't any other code then explicitly say so.  the bug could be elsewhere, or it could be because you do not have a draw loop which is required to process some events such as the mousePressed() function and I assume it's younger sibling, the mousePressed boolean variable.
