Working with Button objects
There are two types of Button objects available in Presentation layouts:
• An interactive object that uses button behaviors: Almost every type of interactive object
includes user events such as Click down (mouse button clicked on object), Click up
(mouse button released on object), and Double click (mouse button double-clicked on
button). By assigning actions to these user events, you can turn almost anything into a
button.
• A Button object containing a multi-state button: A multi-state button is a button that
changes its appearance when it is clicked. Such a button may provide visual feedback to
the end user by having different appearances in its On and Off states. To use a multi-state
button, you must draw the button's various states (or import them as pictures) in a special
type of Interactive layout called a Button layout.
You can also group multiple on/off buttons to create a button group, where only one button
is allowed to be in the On state at any time. This is useful for situations when you want
to limit the end user to one of several mutually exclusive choices.
Creating a multi-state button
To create a multi-state button, you must first create a Button layout. A Button layout is a
special kind of Interactive layout that has a separate page for each state of a multi-state
button.
You can create the following types of multi-state buttons:
• Simple: A Simple button is always either up or down. Simple buttons are good for triggering
a simple action (for example, playing a movie).
• Simple with Disable: A Simple with Disable button is a Simple button with an added state
called Disable.
• On/Off: An On/Off button works like a toggle switch; each click switches it from On to
Off or from Off to On.
• On/Off with Disable: An On/Off with Disable button is an On/Off button with an added
state called Disable.
A multi-state button can have the following states in various combinations:
• Up: The end user has not clicked the button.
• Over: The mouse pointer is over the button, but the end user has not clicked the mouse.
• Down: The end user has clicked the button and it is still down.
