Big TreeView DnD fixage, makes drops on empty models work, makes TreeStore
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.
