+ @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 10 milliseconds.
+
+ Optionally, a CSS class may be applied to the element during the time it is pressed.
+
+ @cfg {String/HTMLElement/Element} 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 10 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. "immediate" is honored.
+ @cfg {Boolean} preventDefault True to prevent the default click event
+ @cfg {Boolean} stopDefault True to stop the default click event
