Can't change GtkWindow size when using GtkBuilder

Question

I'm using GtkBuilder with a Glade XML file. I want to change the size of the window to fullscreen without using the gtk_window_fullscreen method (because this needs to work without a window manager), so I get the screen dimensions and make the window that size. This used to work when I created the widgets programmatically, however when I switched to Glade/GtkBuilder the window is the same small size as it was in Glade editor. Do I have to do something differently with GtkBuilder? Here's the code:

#include <gtk/gtk.h>

int main(int argc, char *argv[]) {
    gtk_init(&argc, &argv);

    GtkBuilder *builder = gtk_builder_new();
    gtk_builder_add_from_file(builder, "dm.ui", NULL);

    GObject *window = gtk_builder_get_object(builder, "window");

    // Make full screen
    GdkScreen *screen = gdk_screen_get_default();
    gint height = gdk_screen_get_height(screen);
    gint width = gdk_screen_get_width(screen);
    gtk_window_set_default_size(GTK_WINDOW(window), width, height);

    g_signal_connect(window, "destroy", G_CALLBACK(gtk_main_quit), NULL);

    gtk_main();
}

Here's the XML file, dm.ui:

<?xml version="1.0" encoding="UTF-8"?>

You can try using

void gtk_widget_set_size_request(GtkWidget *widget, gint width, gint height);

or you can use Glade to adjust GtkWindow properties of "default-width" and "default-height" rather than hardcode it. Let me know the result. p.s : that is why i hate Glade :(
