Code to get a menu item in Qt

There is no easy way to get a menu item in Qt, since its menu structure is something like:
QMenuBar->QAction->QMenu->QAction... So I wrote a piece of code to retrieve certain menu item with its label.

Suppose there's a menu structure [Tools|QA Tools|Memory Monitor], the usage will be something like this (notice that the "&" is required if you have shortcuts defined) :

QStringList path;
path << "&Tools" << "&QA Tools" << "&Memory Monitor"; searchMenuItem(path);

The real code is here:

QAction* MainWindow::searchMenuItem(QAction* submenu, QStringList& path, int layer)
{
   QAction* target = NULL;

   if(submenu->text() == path[layer]){
       target = submenu;
       if(path.count() > layer+1){
           target = searchMenuItem(target, path, layer+1);
       }
   }else{
       QMenu* menu = submenu->menu();
       QList actions = menu->actions();
       foreach(QAction* act, actions){
           if(act->text() == path[layer]){
               target = act;
               if(path.count() > layer+1){ //need to go deep
                   target = searchMenuItem(act, path, layer+1);
               }
               break;
           }else{
               // "ignore action ";
           }
       }
   }

   return target;
}

QAction* MainWindow::searchMenuItem(QStringList path)
{
   if(!path.count()){
       return NULL;
   }

   QAction* target = NULL;

   QMenuBar* menus = this->menuBar();
   Q_ASSERT(menus);
   if(menus){
       QList actions = menus->actions();
       int i=0;
       int layer = 0;
      
       QString mainMenuLabel = path[0];

       foreach(QAction* act, actions){
           if(act->text() == mainMenuLabel){ //found 1st level menu item
               target = act;
               if(path.count() > layer+1){ //need to go deep
                   target = searchMenuItem(act, path, layer+1);
               }
               break;
           }else{
               // "ignore action ";
           }
       }
   }
   return target;
}
