How to convert 'GtkWidget' type in gtk+ to the 'Gtk::Widget' type in gtkmm?

Question

I simply tried this.

GtkWidget* oldwnd = new GtkWidget();
Gtk::Widget wnd(*oldwnd);

But it does not compile.

Can anybody tell me how to type cast the types in gtk+ to the corresponding types in gtkmm?

Perhaps Gtk::Widget* wnd = Glib::wrap(oldwnd)?

documentation says

Gtk::Widget* wrap (GtkWidget* object, bool take_copy=false);

Furthermore, this part of your example makes no sense because you should use a gtk__new() function to instantiate a GTK+ type: GtkWidget oldwnd = new GtkWidget();
