Module: Tea::Event::Dispatch

Defined in:
lib/tea/m_event_dispatch.rb

Overview

The Dispatch mixin gives any object the ability to handle Tea events with method calls. To use it, include the mixin in your class

include Tea::Event::Dispatch

define the handling methods (all optional)

def app_exit; end
def app_restored; end
def app_minimized; end
def kbd_down; end
def kbd_up; end
def mouse_move; end
def mouse_down; end
def mouse_up; end
def mouse_scroll; end

and when you need events handled, call your instance’s dispatch_event method

handler = MyEventHandler.new
...
loop do
  event = Tea::Event.get
  handler.dispatch_event event if event
  ...
end

Tea will then call the method matching the event received.
