What is a button?

A button in Fireworks is an encapsulated rollover that contains all the possible appearances of the button, which represent its various states of use.

You can use the Button Editor to assemble all of these elements—including the slice object, which is the active area for triggering the button—and then place the button in the Fireworks document.

Each button can have up to four unique appearances, or states. Each state represents a button's appearance in response to a pointer action.

	The Up state is the default or "at rest" appearance of the button, when the pointer is away from the button.
	The Over state is the way the button appears when the pointer is moved over it in a Web browser.
	The Down state is the appearance of the button after it has been clicked, usually as it appears on the destination Web page.
	The Over While Down state is the appearance of the button when the pointer is moved over it while the button is in the Down state.

Many buttons on the Web have only two states—Up and Over. The Over state is the most useful state because it typically alerts users that clicking the mouse is likely to do something. The Up and Down states communicate a dormant state, while the Over While Down state typically alerts users that clicking is likely to do nothing at all.
