=== Event Handler reference ===

[[Widget Handlers]] is a complete reference of what event handlers can be used by each object type.

* ''Note'': the OnEvent handler is special (see below).

You will notice that the event handlers in the list mostly cover UI related events. The '''OnEvent''' handler is special in that it is a general, collective handler for a large number of other events. It gets called for any of the remaining hundreds of game related events. See [[Events (API)|Events]] for a list of game events and how to register for them and handle them.
