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

a child |

whether the tab is detachable or not |
Note that 2 notebooks must share a common group identificator
(see gtkNotebookSetGroupId) 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.
on_drop_zone_drag_data_received <- function(widget, context, x, y,
selection_data, info, time,
user_data)
{
notebook <- context$getWidget()
child <- selection_data$data
# unfortunately, it's not possible to actually use 'child' - there
# would need to be a way to derefernce it and make an externalptr
# if you need this functionality, please let the RGtk2 maintainer know.
# process_widget(child)
# notebook$remove(child)
}If you want a notebook to accept drags from other widgets, you will have to set your own DnD code to do it. Since 2.10
