Wed Sep 10 01:06:44 2003 Kristian Rietveld <kris@gtk.org> Big TreeView DnD fixage, makes drops on empty models work, makes TreeStore DnD work and gets rid of gtk-tree-model-drop-append. Related bugs #95362 and #113314. I don't want to touch this code ever again. * gtk/gtktreeprivate.h (GtkTreePrivate): add empty_view_drop field. * gtk/gtktreednd.c (gtk_tree_get_row_drag_data): add check for selection_data->length. * gtk/gtktreeview.c (struct DestRow), (dest_row_free), (set_dest_row), (get_dest_row): we don't store just the row ref anymore, but a struct with the row ref and additional info, (set_destination_row): handle drops on empty space and some style fixes, (get_logical_dest_row): also return path_down_mode/drop_append_mode flags, handle dropping childs on their new parents, rewrite drop append handling into something saner, (gtk_tree_view_drag_motion): show a "drop possible arrow" on empty spaces, (gtk_tree_view_drag_drop): updates for updated backend, (gtk_tree_view_drag_data_received): updates for updated backend, path down mode (treestore DnD) handling, (gtk_tree_view_set_drag_dest_row): set empty_view_drop flag, when we are trying to drop a row on an empty model, (gtk_tree_view_get_drag_dest_row): handle empty_view_drop flag. * gtk/gtkliststore.c (gtk_list_store_drag_data_received), (gtk_list_store_row_drop_possible): style and drop-append fixes. * gtk/gtktreestore.c (gtk_tree_store_drag_data_received): ditto.
