/** * The Multitouch class manages and provides information about the current environment's support for handling * contact from user input devices, including contact that has two or more touch points (such as a user's fingers on a touch screen). * When a user interacts with a device such as a mobile phone or tablet with a touch screen, the user typically * touches the screen with his or her fingers or a pointing device. While there is a broad range of pointing devices, * such as a mouse or a stylus, many of these devices only have a single point of contact with an application. For pointing * devices with a single point of contact, * user interaction events can be handled as a mouse event, or using a basic set of touch events (called "touch point" events). * However, for pointing devices that have several * points of contact and perform complex movement, such as the human hand, Flash runtimes support an additional set of event handling API called gesture events. The API * for handling user interaction with these gesture events includes the following classes: *
Use the listed classes to write code that handles touch events. Use the Multitouch class to determine the * current environment's support for touch interaction, and to manage the support of touch interaction if * the current environment supports touch input.
You cannot create a Multitouch object directly from ActionScript code. If you call
Note: The Multitouch feature is not supported for SWF files embedded in HTML running on Mac OS.
