<!-- ##### SECTION Title ##### -->GtkTreeView drag-and-drop<!-- ##### SECTION Short_Description ##### -->Interfaces for drag-and-drop support in GtkTreeView<!-- ##### SECTION Long_Description ##### --><para>GTK+ supports Drag-and-Drop in tree views with a high-level and a low-level API.</para><para>The low-level API consists of the GTK+ DND API, augmented by some treeview utility functions: gtk_tree_view_set_drag_dest_row(),gtk_tree_view_get_drag_dest_row(), gtk_tree_view_get_dest_row_at_pos(), gtk_tree_view_create_row_drag_icon(), gtk_tree_set_row_drag_data() andgtk_tree_get_row_drag_data(). This API leaves a lot of flexibility, butnothing is done automatically, and implementing advanced features likehover-to-open-rows or autoscrolling on top of this API is a lot of work.</para><para>On the other hand, if you write to the high-level API, then all the bookkeeping of rows is done for you, as well as things like hover-to-open and auto-scroll, but your models have to implement the #GtkTreeDragSource and #GtkTreeDragDest interfaces.</para><!-- ##### SECTION See_Also ##### --><para></para><!-- ##### SECTION Stability_Level ##### --><!-- ##### STRUCT GtkTreeDragSource ##### --><para></para><!-- ##### STRUCT GtkTreeDragSourceIface ##### --><para></para>@g_iface: @row_draggable: @drag_data_get: @drag_data_delete: <!-- ##### FUNCTION gtk_tree_drag_source_drag_data_delete ##### --><para></para>@drag_source: @path: @Returns: <!-- ##### FUNCTION gtk_tree_drag_source_drag_data_get ##### --><para></para>@drag_source: @path: @selection_data: @Returns: <!-- ##### FUNCTION gtk_tree_drag_source_row_draggable ##### --><para></para>@drag_source: @path: @Returns: <!-- ##### STRUCT GtkTreeDragDest ##### --><para></para><!-- ##### STRUCT GtkTreeDragDestIface ##### --><para></para>@g_iface: @drag_data_received: @row_drop_possible: <!-- ##### FUNCTION gtk_tree_drag_dest_drag_data_received ##### --><para></para>@drag_dest: @dest: @selection_data: @Returns: <!-- ##### FUNCTION gtk_tree_drag_dest_row_drop_possible ##### --><para></para>@drag_dest: @dest_path: @selection_data: @Returns: <!-- ##### FUNCTION gtk_tree_set_row_drag_data ##### --><para></para>@selection_data: @tree_model: @path: @Returns: <!-- ##### FUNCTION gtk_tree_get_row_drag_data ##### --><para></para>@selection_data: @tree_model: @path: @Returns:
