Mon Apr 23 18:57:03 2001 Jonathan Blandford <jrb@redhat.com> * gtk/gtksocket.c (gtk_socket_filter_func): add missing '}' that got munched by #endif. * gtk/Makefile.am (gtk_plug_c_sources): add missing '\' * gtk/gtktreeview.c: Refactored code to clean up a number of events. * gtk/gtktreemodel.c (gtk_tree_path_compare): Switched return values to make consistent with other functions. Spotted by Jeff Franks <jcf@tpg.com.au>. * gtk/gtktreeview.h (struct _GtkTreeViewClass): Fixes to signal declaration spotted by Jeff Franks <jcf@tpg.com.au>.
