Call to Action slide sketch (upper left) features a three-panel photographic layout that calls attention to itself as the most important slide in the presentation. As you learned in 7, if you had only one slide to show in a presentation, this one would be it because it both visually concludes Act I and visually summarizes the Key Point slides to come. Each of the three Key Point slides features a split-screen layout along with one of the three graphics from the three panels of the Call to Action slide.

Similarly, you can retrieve a list of methods available on a String object directly:

If the three-panel Call to Action slide layout is one that you think you might use again, create a custom layout as you did earlier, but rename this one CTA. When you create the custom layout, shift the headline to the center of the slide. Insert three Picture placeholders side by side the dimensions for each Picture placeholder are 7.5 inches to ll the slide vertically and 3.3 inches to ll one-third of the 10-inch slide horizontally. Animate each of the placeholders to appear when clicked. After you create and apply the custom layout to the Call to Action slide, insert photographs in each of the Picture placeholders the images will be automatically cropped to t and will appear as shown on the upper left in Figure 8-21. Insert the same three photographs separately into the corresponding Picture placeholders on the Key Point slide layouts (upper right, lower left, and lower right).

Tip To convert a list of characters such as the preceding code back to a string, you would use the following expression:

The results given by the methods method might seem overwhelming at first, but over time they become incredibly useful. Using the methods method on any object allows you

to learn about methods that aren t necessarily covered in this book (or other books), or that are new to the language. You can also use methods to retrieve a list of class methods, because classes are also objects in Ruby! This section provides only a taste of reflection, but the topic is covered in more detail in 6.

It s trivial to override already defined methods on classes. Earlier in this appendix I mentioned that, if you so wish, you can adjust the Fixnum class so that 2 + 2 would equal 5. Here s how you do that:

''.join(somelist)

class Fixnum alias_method :old_plus, :+ def +(other_number) return 5 if self == 2 && other_number == 2 old_plus other_number end end puts 2 + 2
