2003-08-26 Matthias Clasen <maclas@gmx.de> * gtk/gtkuimanager.[hc] (gtk_ui_manager_add_ui_from_string): Use gssize for length, not gsize. * gtk/gtkuimanager.c: Refactor the XML format a bit: rename <Root> to <ui> and make it optional in strings. Rename verb to action, <dockitem> to <toolbar>, <menu> to <menubar>, <submenu> to <menu>. * demos/gtk-demo/appwindow.c: * tests/testactions.c: * tests/testmerge.c: * tests/merge-1.ui: * tests/merge-2.ui: * tests/merge-3.ui: Adjust to the new XML format.
