addFromResource

Parses a resource file containing a UI definition and merges it with the current contents of @builder.

This function is useful if you need to call method@Gtk.Builder.set_current_object to add user data to callbacks before loading GtkBuilder UI. Otherwise, you probably want ctor@Gtk.Builder.new_from_resource instead.

If an error occurs, 0 will be returned and @error will be assigned a GError from the %GTK_BUILDER_ERROR, %G_MARKUP_ERROR or %G_RESOURCE_ERROR domain.

It’s not really reasonable to attempt to handle failures of this call. The only reasonable thing to do when an error is detected is to call g_error().
