/** * @extends Ext.ux.event.Driver * This class manages the playback of an array of "event descriptors". For details on the * contents of an "event descriptor", see {@link Ext.ux.event.Recorder}. The events recorded by the * {@link Ext.ux.event.Recorder} class are designed to serve as input for this class. * * The simplest use of this class is to instantiate it with an {@link #eventQueue} and call * {@link #method-start}. Like so: * * var player = Ext.create('Ext.ux.event.Player', { * eventQueue: [ ... ], * speed: 2, // play at 2x speed * listeners: { * stop: function () { * player = null; // all done * } * } * }); * * player.start(); * * A more complex use would be to incorporate keyframe generation after playing certain * events. * * var player = Ext.create('Ext.ux.event.Player', { * eventQueue: [ ... ], * keyFrameEvents: { * click: true * }, * listeners: { * stop: function () { * // play has completed... probably time for another keyframe... * player = null; * }, * keyframe: onKeyFrame * } * }); * * player.start(); * * If a keyframe can be handled immediately (synchronously), the listener would be: * * function onKeyFrame () { * handleKeyFrame(); * } * * If the keyframe event is always handled asynchronously, then the event listener is only * a bit more: * * function onKeyFrame (p, eventDescriptor) { * eventDescriptor.defer(); // pause event playback... * * handleKeyFrame(function () { * eventDescriptor.finish(); // ...resume event playback * }); * } * * Finally, if the keyframe could be either handled synchronously or asynchronously (perhaps * differently by browser), a slightly more complex listener is required. * * function onKeyFrame (p, eventDescriptor) { * var async; * * handleKeyFrame(function () { * // either this callback is being called immediately by handleKeyFrame (in * // which case async is undefined) or it is being called later (in which case * // async will be true). * * if (async) { * eventDescriptor.finish(); * } else { * async = false; * } * }); * * // either the callback was called (and async is now false) or it was not * // called (and async remains undefined). * * if (async !== false) { * eventDescriptor.defer(); * async = true; // let the callback know that we have gone async * } * } */Ext.define('Ext.ux.event.Player', function (Player) {var defaults = {}, mouseEvents = {}, keyEvents = {}, doc, //HTML events supported uiEvents = {}, //events that bubble by default bubbleEvents = { //scroll: 1, resize: 1, reset: 1, submit: 1, change: 1, select: 1, error: 1, abort: 1 }; Ext.each([ 'click', 'dblclick', 'mouseover', 'mouseout', 'mousedown', 'mouseup', 'mousemove' ], function (type) { bubbleEvents[type] = defaults[type] = mouseEvents[type] = { bubbles: true, cancelable: (type != "mousemove"), // mousemove cannot be cancelled detail: 1, screenX: 0, screenY: 0, clientX: 0, clientY: 0, ctrlKey: false, altKey: false, shiftKey: false, metaKey: false, button: 0 }; }); Ext.each([ 'keydown', 'keyup', 'keypress' ], function (type) { bubbleEvents[type] = defaults[type] = keyEvents[type] = { bubbles: true, cancelable: true, ctrlKey: false, altKey: false, shiftKey: false, metaKey: false, keyCode: 0, charCode: 0 }; }); Ext.each([ 'blur', 'change', 'focus', 'resize', 'scroll', 'select' ], function (type) { defaults[type] = uiEvents[type] = { bubbles: (type in bubbleEvents), cancelable: false, detail: 1 }; }); var inputSpecialKeys = { 8: function (target, start, end) { // backspace: 8, if (start < end) { target.value = target.value.substring(0, start) + target.value.substring(end); } else if (start > 0) { target.value = target.value.substring(0, --start) + target.value.substring(end); } this.setTextSelection(target, start, start); }, 46: function (target, start, end) { // delete: 46 if (start < end) { target.value = target.value.substring(0, start) + target.value.substring(end); } else if (start < target.value.length - 1) { target.value = target.value.substring(0, start) + target.value.substring(start+1); } this.setTextSelection(target, start, start); } }; return { extend: 'Ext.ux.event.Driver', /** * @cfg {Array} eventQueue The event queue to playback.
