[Gtk-sharp-list] Attaching method to events without explicit EventHandler instanciation

[Charles-Henri d'Adhémar]

Hello All !

I am new to mono and GTK# (I am a C++ developer) and I need to
understand something about events handler.
I hope I am in the right place to ask such a question ... If not sorry
for inconvenience !


The way a method is attached to an event seems equivalent in class
Test1 and Test2 below :

class Test1
{

        static void Main()
        {
                ...
                ...
               button1.Clicker += new EventHandler(hello_event);
        }

        public static void hello_event( object o, EventArgs e)
        {
           Console.WriteLine("Button press");
        }
}

class Test2
{

        static void Main()
        {
                ...
                ...
               button1.Clicker += hello_event;
        }

        public static void hello_event( object o, EventArgs e)
        {
           Console.WriteLine("Button press");
        }
}

Can a method (in our case hello_event) be attached to a GTK# event
without instantiating a delegate (new EventHandler(hello_event); ) ?

I have a lots of example on mono's web site and on the web where
methods are attached without invoking the "new EventHandler" syntax,
but I haven't seen any specification or documentation which explicitly
say so (and I have looked for ;-) ).

Any body can help me understanding this ?
Thank you very much in advance !

Cheers,
Chicha
