Moon Travel Planner: Modifying the Default Window

The main window for the Moon Travel Planner application you created in Chapter 3 is rather boring at this point. It shows nothing and is named Window. It will take a few chapters to whip this window into shape so it looks like the sketch in Chapter 2. In this section we’ll get started by doing the following:

1. Open Interface Builder.

2. Revise the window title so it says something other than “Window.”

3. Set Window Class, Controls, and Attributes.

4. Set the window’s size.

5. Build and run the application to make sure it still works after our modifications.

Open Interface Builder

The Interface Builder application is located in the /Developer/Applications folder. Although you can double-click the Interface Builder icon to open it, we’ll open Interface Builder from within Project Builder. Most of the time you’ll have both open and move between them as you modify the interface and add code.

To open Interface Builder from within Project Builder:

1. Open the Moon Travel Planner project if it is not already open.

2. Double-click the main.nib file, located in the Resources group.

Revise the Window Title

The window’s title is the text shown in the title bar (see Figure 4.6). You should change the title from Window to Moon Travel Planner:

1. Double-click the MainWindow icon in the Instances pane.

2. Choose Show Info from the Tools menu.

3. Type Moon Travel Planner in the Title text field, as shown in Figure 4.9 and press Return.
