Step 3: Change the graphics

You may be thinking that this is all very well and good, but all of the objects are the
same. For most applications, different objects are needed. Let's see how we might
modify what we have at this point. As a first step, let's change the background into a
more application-oriented image. Go to the Stage and select the background. In the
Properties window, choose the Swap option as shown in Figure 6.13.

The Swap Symbol dialog box will appear. Select bg2 and click OK. The new background,
shown in Figure 6.14, will appear on the Stage.
