+commonly be the concatenation of a component id and another id marking the specifc history
+state of that component. Example usage:
+ // Handle tab changes on a TabPanel
+tabPanel.on('tabchange', function(tabPanel, tab){
+ Ext.History.add(tabPanel.id + ':' + tab.id);
+});
Parameters:token : StringThe value that defines a particular application-specific history state preventDuplicates : BooleanWhen true, if the passed token matches the current token
+it will not save a new history step. Set to false if the same state can be saved more than once
+at the same history stack location (defaults to true). Returns: | History |
