new way to create events
------------------------

                 Key: GROOVY-5057
                 URL: https://jira.codehaus.org/browse/GROOVY-5057
             Project: groovy
          Issue Type: Wish
         Environment: The better way to handling events in Groovy. Would be very \
good!  Reporter: Jonathan de Sena Ribeiro


I think that the way to handle event in groovy aint the best, would may be that model \
only a 3 simples steps: declaring, dispatching e listening

// 1. declare event
// declare the name and the assignature

public event Click(object sender);

// 2. dispatch event
// execute the event as a method

this.Click(this);

// 3. listening event
// associate a method with a member event in object
// simple, clean and intuitive
// the assignature will bem checked in compile-time

public void Frame_Click(object sender) : testComponent.Click
{
}


/// all code

class TestComponent
{
	public event Click(object sender);

	public void MomentOk()
	{
		Click(this);
	}
}

class TestForm
{
	public TestComponent cmp;

	public main()
	{
		cmp = new TestComponent();
	}
	
	public void Component_Click(object sender) : cmp.Click
	{
		
	}
}
