Example text

As the application goes through its life 27 28 CHAPTER 1: Starting to Build a Graphing Calculator cycle (start, stop, minimize, hide, and so on), the NSApplicationDelegate is notified, and your code can react to these notifications. The application delegate also declares the window attribute, which is set through the graphical interface builder and defines the NSWindow instance to use to materialize the window. We explore the user interface objects in depth in the next chapters. For now, just remember that the application delegate defines the window for the application.

Mac OS X offers an array of user interface widgets that, when intelligently stitched together, fuse to provide stunning and useful interfaces. In this chapter, we explore some of these widgets and how to incorporate them into the Graphique application. The widgets we explore include the following:  Labels, which display static text  Text fields, which allow users to enter text  Buttons, used to let users initiate some action  Toolbars, which display a strip of buttons with images  Split views, which divide a view into two separate views  Sliders, which allow users to select a value by dragging a “thumb” across a range of values  Tables, which display tabular data This chapter focuses only on using Mac OS X’s widgets to create the user interface, not on responding to user input or reacting to events.

If the retention count reaches zero, deallocate the object. Though the pattern is straightforward, its execution often isn’t. Several parts of the code in an application, including framework code not visible to the programmer, can retain objects. Programmers can neglect to send proper retain and release messages or can incorrectly assume that objects are being retained when they aren’t, or vice versa. Also, objects can create cyclical retention graphs, preventing proper releases from occurring.
