2000-06-23 Chris Toshok <toshok@helixcode.com> * e-tree-model.h, e-tree-model.c: add icon_at virtual function - it was stupid to make the insert call take 2 pixbufs. the model should give this information. * e-cell-tree.c: get rid of the opened/closed pixbuf stuff. call e_tree_model_icon_of_node. * e-tree-example-1.c: add my_icon_at. * e-tree-simple.c (simple_icon_at): new function (e_tree_simple_new): add icon_at parameter. * e-tree-simple.h: add SimpleIconAtFn. svn path=/trunk/; revision=3707
