Code

function _fb_canvas_menu_hack() {
  if (fb_canvas_is_fbml()) {

    // We have to go out of our way here to theme the tabs.
    // The code in menu.inc that themes them is complex,
    // incomprehensible, and tangles the theme layer with the logic
    // layer.  It doesn't help that the same theme functions are called
    // for tabs as are called for all other menus.  So we use a global
    // to keep track of what we're doing.
    global $_fb_canvas_state;
    $_fb_canvas_state = 'tabs';

    // Why does a call to menu_tab_root_path theme the tabs?  I have no
    // idea, but it does and caches the result.
    menu_tab_root_path();
    $_fb_canvas_state = NULL;
  }
