One way to achieve what you want is to create your own TextView-derived
class:

public class MyTextView : TextView
{
    public MyTextView() { }

    protected override bool OnButtonPressEvent(Gdk.EventButton e)
    {
        // call base (original) handler
	base.OnButtonPressEvent(e);
        
        // do custom stuff
        Console.WriteLine("event from the textview");
        
        // return that the event was handled
        return true;
    }
}

Then create and use a MyTextView widget instead of the one created by
glade (remember to remove the TextView from the glade file):

...
TextView myTextView=new MyTextView();
win.Add(myTextView);
win.ShowAll();
...

HTH,
