* If you want a widget to interact with a notebook through DnD
* (i.e.: accept dragged tabs from it) it must be set as a drop
* destination and accept the target “GTK_NOTEBOOK_TAB”. The notebook

* widget that corresponds to the dropped tab.
* destination by adding to it a [class@Gtk.DropTarget] controller that accepts
* the GType `GTK_TYPE_NOTEBOOK_PAGE`. The `:value` of said drop target will be
* preloaded with a [class@Gtk.NotebookPage] object that corresponds to the
* dropped tab, so you can process the value via `::accept` or `::drop` signals.
*
* Note that you should use [method@Gtk.Notebook.detach_tab] instead
* of [method@Gtk.Notebook.remove_page] if you want to remove the tab
