[Gtk-sharp-list] Glade signals with GtkSharp handlers

[Calvin Gaisford]

Joe,

You need to sub-class the EventArgs class.  Something like this:

public class MyEventArgs : EventArgs
{
	private readonly string str;

	public MyEventArgs(string str)
	{
		this.str = str;
	}

	public string StrValue
	{
		get { return str;}
	}
}

You can delare your delegate like this:

public delegate void MyEventHandler(object sender, MyEventArgs args);

In the class you want to signal the event declare the event something
like this:

public event MyEventHandler MyEventName;

To signal the event in your class do something like this:

MyEventArgs args = new MyEventArgs("Whatever String I am passing");
MyEventName(this, args);

A class connecting to your event would declare a handler like this:

public void OnMyEventName(object o, MyEventArgs args)
{
	string eventString = args.StrValue;
}

and they would connect their handler to your delegate like this:

whateverobject.MyEventName += new MyEventHandler(OnMyEventName);

I hope that helps.
