Gestures

Gestures

Enyo supports a set of cross-platform gesture events that work similarly on all supported platforms. These events are provided so that users can write a single set of event handlers for applications that run on both mobile and desktop platforms. They are needed because desktop and mobile platforms handle basic gestures differently. For example, desktop platforms provide mouse events, while mobile platforms support touch events and a limited set of mouse events for backward compatibility.

Gesture Events

Enyo provides the following gesture events, which are synthesized from the available DOM events:

• down is generated when the pointer is pressed down.

• up is generated when the pointer is released up.

• tap is generated when the pointer is pressed down and released up. The target is the lowest DOM element that received both the related down and up events.

• move is generated when the pointer moves.

• enter is generated when the pointer enters a DOM node.

• leave is generated when the pointer leaves a DOM node.

Please note that Enyo's gesture events are generated on Enyo controls, not DOM elements.
