Question

I’ve started new Gtk# solution with MonoDevelop. Now where I can put global exception handler that popups a dialog to user with stack traces etc? Is there any existing libraries that can do this?

Something like https://exceptionreporter.codeplex.com/

Main.cs:

using System;
using Gtk;

namespace foobar
{
    class MainClass
    {
        public static void Main (string[] args)
        {
            Application.Init ();
            MainWindow win = new MainWindow ();
            win.Show ();
            Application.Run ();
        }
    }
}

MainWindow.cs:

using System;
using Gtk;

public partial class MainWindow: Gtk.Window
{   
    public MainWindow (): base (Gtk.WindowType.Toplevel)
    {
        Build ();
    }

    protected void OnDeleteEvent (object sender, DeleteEventArgs a)
    {
        Application.Quit ();
        a.RetVal = true;
    }
}

You can use the GLib.ExceptionManager.UnhandledException event.

Its argument of type GLib.UnhandledExceptionArgs Class contains an ExitApplication property that can be used to control whether the application should exit due to the exception.
