Hi, Martin--
Here's a short example that might illustrate what you're trying to
accomplish:
require "System.Windows.Forms"
include System
include System::Windows::Forms
button = Button.new
click_event = button.GetType.get_event("Click")
on_click = EventHandler.new { |sender, e| puts "Click!" }
click_event.add_event_handler(button, on_click)
button.perform_click # Click!
click_event.remove_event_handler(button, on_click)
button.perform_click
More canonical examples of using events in IronRuby are found here:
