we can remove nodes with children now.
2000-08-21 Chris Toshok <toshok@helixcode.com> * e-tree-example-1.c (remove_node): we can remove nodes with children now. * e-tree-model.h: add prototype for e_tree_model_node_sort. * e-tree-model.c (etree_set_expanded): if the node is invisible, just set its expanded flag and return. (e_tree_model_root_node_set_visible): call set_expanded before we remove it from the row array or else the aforementioned change will result in nothing happening. (e_tree_model_node_insert): use a position of -1 as "append". (e_tree_model_node_insert): if the model was marked with root_visible == FALSE, make sure to set it's expanded flag to TRUE when the root node is inserted. (e_tree_model_node_sort): new function. svn path=/trunk/; revision=4912
