The Four Button Frames

The button's Timeline consists of four named frames (see Figure 7.1): Up, Over, Down, and Hit. See Table 7.1 for their descriptions.

Figure 7.1. The button's Timeline consists of four named frames.

TIP

The end user can see only the contents of the first three states or frames of a button. Since the Hit frame defines the clickable area of a button, it is not visible to the end user .
