Moon Travel Planner: Adding Objectsto the Main Window

In the last chapter, you set up the main window for the Moon Travel Planner application. Now, you’ll add objects to the main window so the window looks like the one we specified in Chapter 2. You’ll need to do the following:

  1. Open the nib file.

  2. Add an item from the Enhanced Controls palette.

  4. Add a PICT resource to the project.

  5. Align objects.

  2. Click the Enhanced Controls button in the palette toolbar.
