Fri Apr 4 17:30:27 2003 Owen Taylor <otaylor@redhat.com> * gtkfilechooserprivate.h gtkfilechooser.h: Move interface definition into a private header so it can refer to GtkFileSystem. * *.[ch]: Switch over from using gchar *uri internally to using GtkFilePath * internally, and add conversion routines to GtkFileSystem. * TODO README: Updates.
