16 @class Ext.util.ClickRepeater
17 @extends Ext.util.Observable
19 A wrapper class which can be applied to any element. Fires a "click" event while the
20 mouse is pressed. The interval between firings may be specified in the config but
21 defaults to 20 milliseconds.
23 Optionally, a CSS class may be applied to the element during the time it is pressed.
25 @cfg {Mixed} el The element to act as a button.
26 @cfg {Number} delay The initial delay before the repeating event begins firing.
27 Similar to an autorepeat key delay.
28 @cfg {Number} interval The interval between firings of the "click" event. Default 20 ms.
29 @cfg {String} pressClass A CSS class name to be applied to the element while pressed.
30 @cfg {Boolean} accelerate True if autorepeating should start slowly and accelerate.
31 "interval" and "delay" are ignored.
32 @cfg {Boolean} preventDefault True to prevent the default click event
33 @cfg {Boolean} stopDefault True to stop the default click event
