11 * Adds functionality to simulate events.
13 * @submodule node-event-simulate
17 * Simulates an event on the node.
18 * @param {String} type The type of event (i.e., "click").
19 * @param {Object} options (Optional) Extra options to copy onto the event object.

26 Y.Event.simulate(Y.Node.getDOMNode(this), type, options);
30 * Simulates the higher user level gesture of the given name on this node.
31 * This method generates a set of low level touch events(Apple specific gesture
32 * events as well for the iOS platforms) asynchronously. Note that gesture
33 * simulation is relying on `Y.Event.simulate()` method to generate
34 * the touch events under the hood. The `Y.Event.simulate()` method
35 * itself is a synchronous method.
37 * Supported gestures are `tap`, `doubletap`, `press`, `move`, `flick`, `pinch`
40 * The `pinch` gesture is used to simulate the pinching and spreading of two
41 * fingers. During a pinch simulation, rotation is also possible. Essentially
42 * `pinch` and `rotate` simulations share the same base implementation to allow
43 * both pinching and rotation at the same time. The only difference is `pinch`
44 * requires `start` and `end` option properties while `rotate` requires `rotation`
47 * The `pinch` and `rotate` gestures can be described as placing 2 fingers along a
48 * circle. Pinching and spreading can be described by start and end circles while
49 * rotation occurs on a single circle. If the radius of the start circle is greater
50 * than the end circle, the gesture becomes a pinch, otherwise it is a spread spread.
54 * var node = Y.one("#target");
56 * // double tap example
57 * node.simulateGesture("doubletap", function() {
58 * // my callback function
61 * // flick example from the center of the node, move 50 pixels down for 50ms)
62 * node.simulateGesture("flick", {
67 * // my callback function
70 * // simulate rotating a node 75 degrees counter-clockwise
71 * node.simulateGesture("rotate", {
75 * // simulate a pinch and a rotation at the same time.
76 * // fingers start on a circle of radius 100 px, placed at top/bottom
77 * // fingers end on a circle of radius 50px, placed at right/left
