2000-11-03 Not Zed <NotZed@HelixCode.com> * e-tree-model.c (e_tree_model_node_insert): Since we insert at the parent->child position, we need to account for expanded nodes above this node to properly calculate the absolute row position of the node. (e_tree_model_node_insert): If we're inserting at the end of this node, then we just use the position directly. (e_tree_model_node_remove): Completely rewritten. Now we delete all nodes at once, which should be >> faster, unfortunately still have to signal each removal, which is >> SLOW :( Its still about 2-3x faster than it was (for 25K nodes). (child_free): Free all data/subnodes of a given path, no unlinking. (e_tree_model_node_remove): If we are removing a lot of nodes [>1000 or >1/4 total nodes], then use model_changed, rather then removing each node. Yay. Now its about 500x faster than it was, for 25K nodes. (etree_pre_change): Signal handler, so we can find out when we are in a pre-change state. (etree_changed): Likewise to find when we have finished. (e_tree_model_construct): Link to the model*changed signals so we know when we are in pre/changed state. (e_tree_model_node_insert): Only perform a row_inserted if not in pre_change state. Another significant speed improvement (200-500%) on big trees. (e_tree_model_node_remove): Do not emit row_deleted (or model_changed), if we are in the pre_change state. (add_visible_descendents_to_array): Likewise for row_inserted. (e_tree_model_node_sort): And here too, for consistency. svn path=/trunk/; revision=6363
