set_tab_detachable

Sets whether the tab can be detached from this to another notebook or widget.

Note that 2 notebooks must share a common group identificator (see set_group_name) to allow automatic tabs interchange between them.

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 will fill the selection with a GtkWidget** pointing to the child widget that corresponds to the dropped tab.

Note that you should use detach_tab instead of remove if you want to remove the tab from the source notebook as part of accepting a drop. Otherwise, the source notebook will think that the dragged tab was removed from underneath the ongoing drag operation, and will initiate a drag cancel animation.

 static void
 on_drag_data_received (GtkWidget				*widget,
												GdkDragContext	 *context,
												gint							x,
												gint							y,
												GtkSelectionData *data,
												guint						 info,
												guint						 time,
												gpointer					user_data)
 {
	 GtkWidget *notebook;
	 GtkWidget **child;

	 notebook = gtk_drag_get_source_widget (context);
	 child = (void*) gtk_selection_data_get_data (data);

	 // process_widget (*child);

	 gtk_notebook_detach_tab (GTK_NOTEBOOK (notebook), *child);
 }

If you want a notebook to accept drags from other widgets, you will have to set your own DnD code to do it.
