In 4, you learned a bit about some of Cocoa s most common GUI components, from buttons and simple input fields to full-fledged text editors. We haven t yet talked about one of Cocoa s biggest, most complex view classes, NSTableView. In this chapter, you ll learn how to use an NSTableView to display data for whole collection of components, how to respond when the user changes the table s selection by clicking a row, and how to edit values right in the table. You ll learn how to use a table view by extending the VillainTracker application from 4. The new version of VillainTracker we create in this chapter will maintain an array of villains, display them all in a table, and let the user edit all the attributes of the selected villain when they click on its entry in the table. We ll start by using Xcode to extend the AppController class s interface to include an array of villains, some new outlets for connecting to the new table view and the window itself, and action methods for adding and deleting villains. Then we ll prepare the GUI layout in Interface Builder, and then we ll go back to Xcode to implement the changes to our controller s implementation for handling the table. Figure 5-1 shows you the end-result we re shooting for.

Optimistic and pessimistic locking compared An optimistic approach always assumes that everything will be OK and that conflicting data modifications are rare. Instead of being pessimistic and blocking concurrent data access immediately (and forcing execution to be serialized), optimistic concurrency control only blocks at the end of a unit of work and raises an error. Both strategies have their places and uses, of course. Multi-user applications usually default to optimistic concurrency control and use pessimistic locks when appropriate. Note that the duration of a pessimistic lock in NHibernate is a single database transaction! This means you can t use an exclusive lock to block concurrent access longer than a single database transaction. We consider this a good thing, because the only solution would be an extremely expensive lock held in memory (or a so-called lock table in the database) for the duration of, for example, a conversation. This is almost always a performance bottleneck; every data access involves additional lock

If you have a tablet PC, an external drawing pad, or perhaps one of the newer tablet form factors that we re just dreaming about as I write this, then ink input using a stylus is a must. Ink is also a nice way to capture drawings done with the mouse. Most keyboard input will be handled by the TextBox and similar controls. But what happens when you want to implement custom accelerators or write a game that responds to keystrokes In those instances, you ll need to access the lower-level keyboard events like I did in the Commodore 64 emulator shown in chapter 5. The keyboard has been our input of choice since the dawn of terminal-based computing (no, Silverlight doesn t have a paper tape input API, but you could probably write one) and is used by virtually all applications, so we ll start there.

While you re still in Xcode, add another method to the WindowLabAppDelegate class:
