There are a couple of different ways of doing this with GTK. To go full screen:

  GtkWidget *window;
  gdk_window_move_resize (window->window, 0, 0, gdk_screen_width(), gdk_screen_height());
  gtk_window_set_default_size (GTK_WINDOW (window), gdk_screen_width(), gdk_screen_height());
  gtk_widget_set_usize (window, gdk_screen_width(), gdk_screen_height());

This will hide all WM decorations and show only your window contents.
Anyway, there are GTK functions to explicitly hide WM decorations and
their functionality.

If you only have a drawing area inside the window, it will go full screen.
If there are widgets in the window that you want to hide, you can use:
  gtk_widget_hide (widget);

If you want to save the window geometry before going full screen, so
later on you can go back, you can use, for example:

  gdk_window_get_size (window->window, &w, &h);
  gdk_window_get_origin (window->window, &x, &y);

However, there's one thing I still don't know, which is: how can I hide
the tools provided by the WM? say, tool bars, desktop bars and such?
