To use the Alert component, you drag an Alert component to the Stage and delete it so that the
component is in the document library but not visible in the application. Then you call
Alert.show() to display an Alert window. You can pass parameters to Alert.show() that add a
message, a title bar, and buttons to the Alert window.
Because ActionScript is asynchronous, the Alert component is not blocking, which means that
the lines of ActionScript code that follow the call to
Alert.show() run immediately. You must
add listeners to handle the
click events that are broadcast when a user clicks a button and then
continue your code after the event is broadcast.
Note: In operating environments that are blocking (for example, Microsoft Windows), a call to
Alert.show() does not return until the user has taken an action, such as clicking a button.
