2000-12-20 Havoc Pennington <hp@redhat.com> * tests: new directory to contain tests, gtk/test* should move here sometime (with appropriate on-cvs-server hackery) * tests/testtreeview.c, tests/Makefile.am: a test * configure.in (AC_OUTPUT): add tests/Makefile * gtk/gtktexttag.c (gtk_text_tag_get_property): Add "invisible" and "invisible_set" which were missing * gtk/gtkrbtree.h: some cheesy indentation fix
