Drag & Drop example code

[David Gasa i Castell <dgasacas7 gmail com>]

Hi guys,

I'd need to understand how to use Drag & Drop facilities in Gtkmm-4.x to reorder GtkListItem(s) in a GtkListView.

Could you provide a simple (but complete) example code ?

Or maybe to complete the example code in https://github.com/GNOME/gtkmm/blob/master/demos/gtk-demo/example_listview_columnview.cc
