iterator.next().contains("service") doesn't work properly

[jakubiszon26]

HI i'm trying to show in my list widget only files that ends with .service.
i made this:

QDirIterator iterator("/lib/systemd/system/");
   ui->servicesList->clear();
   while(iterator.hasNext()){
       if(!iterator.next().contains("service")){
           return;
       }
       ui->servicesList->addItem(iterator.next());
   }

but in my list i can see positions with .target and .socket do you know what's wrong? thanks

QDirIterator iterator("/lib/systemd/system/");
   ui->servicesList->clear();
   while(iterator.hasNext()){
       const auto current = iterator.next();
       if(current.contains("service"))
       ui->servicesList->addItem(current );
   }

@jakubiszon26 said in iterator.next().contains("service") doesn't work properly:

iterator.next()

According to the documentation: "Advances the iterator to the next entry, and returns the file path of this new entry. "

return;

this is wrong I would guess

QDirIterator iterator("/lib/systemd/system/");
   ui->servicesList->clear();
   while(iterator.hasNext()){
       const auto current = iterator.next();
       if(current.contains("service"))
       ui->servicesList->addItem(current );
   }
