Documentation for ActionScript classes includes syntax, usage information, and code samples for methods, properties, and event handlers and listeners that belong to a specific class in ActionScript (as opposed to global functions or properties). The classes are listed alphabetically and include classes that were new in Flash Player 8 and are found in the flash.* packages. If you are not sure to which class a certain method or property belongs, you can look it up in the Index.

|The DisplacementMapFilter class uses the pixel values from the specified BitmapData object (called the displacement map image) to perform a displacement of an object on the Stage, such as a MovieClip instance.
|The DropShadowFilter class lets you add a drop shadow to a variety of objects in Flash.
|Contains information about an error that occurred in a script.
|The FileReference class provides a means to upload and download files between a user's computer and a server.
|The FileReferenceList class provides a means to let users select one or more files for uploading.
|Both user-defined and built-in functions in ActionScript are represented by Function objects, which are instances of the Function class.
|The GlowFilter class lets you apply a glow effect to various objects in Flash.
|The GradientBevelFilter class lets you apply a gradient bevel effect to various objects in Flash.
|The GradientGlowFilter class lets you apply a gradient glow effect to a variety of objects in Flash.
|The IME class lets you directly manipulate the operating system's input method editor (IME) in the Flash Player application that is running on a client computer.
|The Key class is a top-level class whose methods and properties you can use without a constructor.
|You can use the LoadVars class to obtain verification of successful data loading and to monitor download progress.
|The LocalConnection class lets you develop SWF files that can send instructions to each other without the use of
|The mx.lang.Locale class allows you to control how multilanguage text is displayed in a SWF file.
|The Math class is a top-level class whose methods and properties you can use without using a constructor.
|The flash.geom.Matrix class represents a transformation matrix that determines how to map points from one coordinate space to another.
|The Microphone class lets you capture audio from a microphone attached to the computer that is running Flash Player.
|The Mouse class is a top-level class whose properties and methods you can access without using a constructor.
|The methods for the MovieClip class provide the same functionality as actions that target movie clips.
|This class lets you implement listener callbacks that provide status information while SWF, JPEG, GIF, and PNG files are being loaded into movie clips.
|The NetConnection class provides the means to play back streaming FLV files from a local drive or HTTP address.
|The NetStream class provides methods and properties for playing Flash Video (FLV) files from the local file system or an HTTP address.
|The Number class is a simple wrapper object for the Number data type.
|The Object class is at the root of the ActionScript class hierarchy.
|The Point class represents a location in a two-dimensional coordinate system, where x represents the horizontal axis and y represents the vertical axis.
|The PrintJob class lets you create content and print it to one or more pages.
|The Rectangle class is used to create and modify Rectangle objects.
|The System.security class contains methods that specify how SWF files in different domains can communicate with each other.
|The Selection class lets you set and control the text field in which the insertion point is located (that is, the field that has focus).
|Shared objects offer real-time data sharing between multiple SWF files.
|The Sound class lets you control sound in a movie.
|The Stage class is a top-level class whose methods, properties, and handlers you can access without using a constructor.
|The String class is a wrapper for the string primitive data type, and provides methods and properties that let you manipulate primitive string value types.
|The StyleSheet class lets you create a StyleSheet object that contains text formatting rules for font size, color, and other styles.
|The System class contains properties related to certain operations that take place on the user's computer, such as operations with shared objects, local settings for cameras and microphones, and use of the Clipboard.
|The TextField class is used to create areas for text display and input.
|The TextFormat class represents character formatting information.
|The TextRenderer class provides functionality for the advanced anti-aliasing capability of embedded fonts.
|TextSnapshot objects let you work with static text in a movie clip.
|The Transform class collects data about color transformations and coordinate manipulations that are applied to a MovieClip object.
|The Video class enables you to display live streaming video on the Stage without embedding it in your SWF file.
|Use the methods and properties of the XML class to load, parse, send, build, and manipulate XML document trees.
|An XML document is represented in Flash by the XML class.
|The XMLSocket class implements client sockets that let the computer running Flash Player communicate with a server computer identified by an IP address or domain name.
|The XMLUI object enables communication with SWF files that are used as custom user interfaces for the Flash authoring tool's extensibility features (such as Behaviors, Commands, Effects, and Tools).
