I made a custom slider component and I am trying to customize the slider for my purposes. I would like functionality such as addListener(), removeCls(), and visible(false). I would like to change the css and perform actions after render. I see in the sencha docs that none of these methods are available to Thumb, and my own attempts failed likewise. However, I found the below example where a person was successful with addListener in Sencha Touch. Surely this functionality is available for Ext JS web?
