/** @class Ext.util.ClickRepeater @extends Ext.util.Observable A wrapper class which can be applied to any element. Fires a "click" event while the mouse is pressed. The interval between firings may be specified in the config but defaults to 20 milliseconds. Optionally, a CSS class may be applied to the element during the time it is pressed. @cfg {Mixed} el The element to act as a button. @cfg {Number} delay The initial delay before the repeating event begins firing. Similar to an autorepeat key delay. @cfg {Number} interval The interval between firings of the "click" event. Default 20 ms. @cfg {String} pressClass A CSS class name to be applied to the element while pressed. @cfg {Boolean} accelerate True if autorepeating should start slowly and accelerate. "interval" and "delay" are ignored. @cfg {Boolean} preventDefault True to prevent the default click event @cfg {Boolean} stopDefault True to stop the default click event @history 2007-02-02 jvs Original code contributed by Nige "Animal" White 2007-02-02 jvs Renamed to ClickRepeater 2007-02-03 jvs Modifications for FF Mac and Safari @constructor @param {Mixed} el The element to listen on @param {Object} config */ Ext.util.ClickRepeater = function(el, config) { this.el = Ext.get(el); this.el.unselectable(); Ext.apply(this, config); this.addEvents( /** * @event mousedown * Fires when the mouse button is depressed. * @param {Ext.util.ClickRepeater} this */ "mousedown", /** * @event click * Fires on a specified interval during the time the element is pressed. * @param {Ext.util.ClickRepeater} this */ "click", /** * @event mouseup * Fires when the mouse key is released. * @param {Ext.util.ClickRepeater} this */ "mouseup" ); if(!this.disabled){ this.disabled = true; this.enable(); } // allow inline handler if(this.handler){ this.on("click", this.handler, this.scope || this); } Ext.util.ClickRepeater.superclass.constructor.call(this); }; Ext.extend(Ext.util.ClickRepeater, Ext.util.Observable, { interval : 20, delay: 250, preventDefault : true, stopDefault : false, timer : 0, /** * Enables the repeater and allows events to fire. */ enable: function(){ if(this.disabled){ this.el.on('mousedown', this.handleMouseDown, this); if(this.preventDefault || this.stopDefault){ this.el.on('click', this.eventOptions, this); } } this.disabled = false; }, /** * Disables the repeater and stops events from firing. */ disable: function(/* private */ force){ if(force || !this.disabled){ clearTimeout(this.timer); if(this.pressClass){ this.el.removeClass(this.pressClass); } Ext.getDoc().un('mouseup', this.handleMouseUp, this); this.el.removeAllListeners(); } this.disabled = true; }, /** * Convenience function for setting disabled/enabled by boolean. * @param {Boolean} disabled */ setDisabled: function(disabled){ this[disabled ?
