TreeDragSource
===================================================================

.. currentmodule:: gi.repository.Gtk





.. deprecated:: 4.10

   List views use widgets to display their contents.
     You can use :obj:`~gi.repository.Gtk.DragSource` to implement a drag source


.. class:: TreeDragSource(*args, **kwargs)
   :no-contents-entry:





Implementations: :class:`~gi.repository.Gtk.ListStore`, :class:`~gi.repository.Gtk.TreeModelFilter`, :class:`~gi.repository.Gtk.TreeModelSort`, :class:`~gi.repository.Gtk.TreeStore`


Interface for Drag-and-Drop destinations in ``GtkTreeView``\.




Methods
-------

.. rst-class:: interim-class

.. class:: TreeDragSource
   :no-index:


   .. method:: drag_data_delete(path: ~gi.repository.Gtk.TreePath) -> bool

      Asks the ``GtkTreeDragSource`` to delete the row at ``path``\, because
      it was moved somewhere else via drag-and-drop. Returns :const:`False`
      if the deletion fails because ``path`` no longer exists, or for
      some model-specific reason. Should robustly handle a ``path`` no
      longer found in the model!





      .. deprecated:: 4.10

         Use list models instead



      :param path: row that was being dragged




   .. method:: drag_data_get(path: ~gi.repository.Gtk.TreePath) -> ~gi.repository.Gdk.ContentProvider | None

      Asks the ``GtkTreeDragSource`` to return a ``GdkContentProvider`` representing
      the row at ``path``\. Should robustly handle a ``path`` no
      longer found in the model!





      .. deprecated:: 4.10

         Use list models instead



      :param path: row that was dragged




   .. method:: row_draggable(path: ~gi.repository.Gtk.TreePath) -> bool

      Asks the ``GtkTreeDragSource`` whether a particular row can be used as
      the source of a DND operation. If the source doesn’t implement
      this interface, the row is assumed draggable.





      .. deprecated:: 4.10

         Use list models instead



      :param path: row on which user is initiating a drag
