Help on connecting glade objects gtk3

[xaviblas (Xavier de Blas)]

Hello, I feel dumb, but migrating my app from gtk2 (libglade) to gtk3 (gtkbuilder) I done this example.

Compile with:
mcs win2labels.cs -pkg:gtk-sharp-3.0

It works but I want to do it without having to this for each object:

label1 = (Gtk.Label) builder.GetObject(“label1”);

In the past (with libglade, gtk2) it worked everything right with the autoconnect, but now I do not succeed. Any help?

Also I can’t find any c-sharp gtk3 software to inspect the code.

Thanks

using System;
using Gtk;

public class main
{ 
        static Win2labels win2labels;
    
        public static void Main (string[] args)
        {
                Gtk.Application.Init (); //needed
                win2labels = Win2labels.Show ();
                Gtk.Application.Run ();
        }   
}           
            
public class Win2labels
{         
        static Win2labels Win2labelsBox;
            
        Gtk.Window window;
        Gtk.Label label1;
        Gtk.Label label2;
        
        public Win2labels ()
        {   
                Builder builder = new Builder();
                builder.AddFromFile ("win2labels.glade");

                window = (Gtk.Window) builder.GetObject("window");
  
                //can this program work without next two lines?
                label1 = (Gtk.Label) builder.GetObject("label1");
                label2 = (Gtk.Label) builder.GetObject("label2");
    
                //builder.Autoconnect (window);
                builder.Autoconnect (this);
        
                label1.Text = "Hello!";
                label2.Text = "Bye!";
        } 
            
        static public Win2labels Show ()
        {   
                Win2labelsBox = new Win2labels ();
                Win2labelsBox.window.Show ();
            
                return Win2labelsBox;
        }   
}

In Vim I can do:

:'<,'>s/Gtk.Label \(.*\);/\1 = (Gtk.Label) builder.GetObject ("\1");

to convert this:

         Gtk.Label label_about;
         Gtk.Label label_radio_jumps;
         Gtk.Label label_radio_races;
         Gtk.Label label_radio_other;

to this:

         label_about = (Gtk.Label) builder.GetObject ("label_about");
         label_radio_jumps = (Gtk.Label) builder.GetObject ("label_radio_jumps");
         label_radio_races = (Gtk.Label) builder.GetObject ("label_radio_races");
         label_radio_other = (Gtk.Label) builder.GetObject ("label_radio_other");

But I have 3445 widgets needing to be connected and it’s just to not have to do all that if it is necessary.
I wonder if I’m doing something wrong or it’s a bug.

Also I see in this example that all the widgets are connected line by line:

Finally I’ve been able to migrate to GTK3!

I added thousands of lines related to need of builder.GetObject, but it works!
