Is it possible to subclass the rootwidget?

[BurningTreeC]

Hi all,

I have a question regarding the rootwidget
I'd like to extend a method in a plugin I'm writing
Is that possible through something like a subclassing mechanism?

Best wishes,
Simon

Hi @BurningTreeC if you only want your new properties to be available on the root widget, and not other instances of the widget base class, then you should be able to poke those methods into the existing instance with something like $tw.rootWidget.myMethod = function() {...}.

Thank you @Jermolene , I think I haven't been precise enough
In the exports.startup function I'd like to modify an EventListener without overwriting the core rootwidget.js tiddler
Is that even possible?

[Jermolene]

It sounds like those event listeners would need to be refactored as methods that you could override. What is the tm- message you are thinking about?

[BurningTreeC]

Thanks for your answer @Jermolene . The message I'd like to override is the tm-focus-selector message. I really want to apply an optional delay to it through setTimeout

[Jermolene]

Perhaps you could implement your variant as a separate message tm-focus-selector-deferred?
