[Unity] Casting sender to Button in its Click handler

27 Jun 2014, 22:52

If I define a button and add an event handler for its Click event, I get a method that has a sender parameter of type BaseComponent, and an e parameter of type RoutedEventArgs. Since I may have multiple buttons that all use this event handler, I want to figure out which button has fired the event. In WPF, I'd just cast the sender argument to a Button:
var button = sender as Button;
However, this doesn't work in NoesisGui. I can't seem to cast the BaseComponent to anything, and can't really do anything with the sender argument.

How do get a reference to the Button that fired the click event from the event handler?

You can call on the BaseComponent As<Button>();

Plus one -- very helpful, thanks. (Had to use Noesis.Button.GetIsMouseOver() before that).

We are aware that this is not the standard way to cast in c#. It should work with the 'as' keyword. It is something we have in our To Do list.
