2000-06-08 Chris Toshok <toshok@helixcode.com> * e-tree-gnode.c, e-tree-gnode.h: New files. A tree model using a GNode structure to store it's info. * e-tree-model.c, e-tree-model.h: New files. A proxy model sitting between a table model and the real tree model (of which ETreeGNode is an example). * e-cell-tree.c, e-cell-tree.h: New files. A cell renderer capable of wrapping up a subcell and drawing the tree controls for expanding/collapsing trees. * tree-expanded.xpm, tree-unexpanded.xpm: New files. the standard + and - icons. * e-tree-example-1.c: New file, giving a (pretty poor :) example of using ETreeGNode. * Makefile.am: at the tree stuff to the build, and build tree-example-1. * .cvsignore: ignore tree-example-1. svn path=/trunk/; revision=3483
