abstract class EventHandler::Event

• EventHandler::Event
• Reference
• Object

Overview

Basic event class; all events must inherit from Event.

This abstract class is generally not used directly; see macro event.

To extend the class produced by event if needed, either reopen the class after defining it with event:

event ClickedEvent, x : Int32, y : Int32

class ClickedEvent < ::EventHandler::Event
  property test : String
end

or create the whole class manually:

class ClickedEvent < ::EventHandler::Event
  getter x : Int32
  getter y : Int32
  property test : String

  def initialize(@x, @y)
  end
end
