how to constrain the cursor in just one screen.

Hi, I'm working a GTK based applicaion, which uses double screens. Without any constraint, the user can move the cursor freely from one scrren to another. Now, I want to constrain the cursor in just one screen. How can I do it? Is there a gtk function which can help me solve my problem? Andy
