This session will explore how to extend the functionality of Perforce clients with the power of HTML, CSS, and JavaScript. The vision for these applets is to be portable across P4V, P4Admin, P4Eclipse, and a browser. The toolkit will define an object model and will handle events, selections, and other services. The Perforce JavaScript API is more than a cool new feature for customers: it also provides a platform for internal innovation on Perforce's flagship GUI and beyond. Quick prototyping brings touchable validation for ideas to a wide range of employees across the organization.
