* True if this button is disabled. Read-only.
*
* disabled: false,
*
*
* @property {Boolean} pressed
* True if this button is pressed (only if enableToggle = true). Read-only.
*
* pressed: false,
*
*
* @cfg {Boolean} [allowDepress=true]
* False to not allow a pressed Button to be depressed. Only valid when {@link #enableToggle} is true.
*
* @cfg {String/Object} hint
* The tooltip for the button - can be a string to be used as bootstrap tooltip
