The button is a special interactive object. It responds automatically to the user by changing its appearance when you move the mouse over it or click on it. In fact, each button has four different appearances, or "states," built into it: Up, Down, Highlight, and Disabled.
There's a different image for each state built right into the button file. By switching between these images, a button can appear animated and interactive—glowing when the user moves the mouse over it, for instance, and appearing pushed in when the user clicks on it. With full support for alpha transparency and variable opacity, buttons can even come with built-in drop shadow effects and have smooth, rounded edges.
Buttons are a great place to put actions, since they usually look like something you would want to click on. And to help the user know what the buttons will do, each button can have custom text on it, just like a label object. The text can even change color in each of the different states, so it fits in with each state's appearance perfectly.
Buttons come in all shapes, sizes and colors. The professionally-designed buttons that come with AutoPlay resize well and even look great when they're stacked on top of each other, thanks to the built-in drop shadows which give our buttons a nice, three-dimensional appearance.
Tip: An easy way to add a button object is to drag and drop a button file (.btn) onto the page or dialog surface. You can also add a button object by choosing Object > Button from the menu.
