So, this is a part of my "linked_list.h" header: <pre><code>template <typename T> class Linked_list { public: Linked_list(); ~Linked_list(); void add_first(const T& x); //... }; </code></pre> And a part of my implementation: <pre><code>template <typename T> line 22: void Linked_list<T> :: add_first(const T& x) { Node<T>* aux; aux = new Node<T>; aux->info = x; aux->prev = nil; aux->next = nil->next; nil->next->prev = aux; nil->next = aux; } </code></pre> and I'm trying to make a linked list of linked lists of strings and add strings in one linked list of my linked list, like this: <pre><code>Linked_list<Linked_list<string> > *l; l[0]->add_first("list"); //also I've tried l[0].add_first("list"); but it didn't work either </code></pre> Thank you. Later edit: When I try l[0]->add_first("list") these are the errors: <pre><code>main.cc: In function ‘int main()’: main.cc:22:22: error: no matching function for call to‘Linked_list<Linked_list<std::basic_string<char> > >::add_first(const char [4])’ main.cc:22:22: note: candidate is: In file included from main.cc:6:0: linked_list.cc:28:6: note: void Linked_list<T>::add_first(const T&) [with T = Linked_list<std::basic_string<char> >] linked_list.cc:28:6: note: no known conversion for argument 1 from ‘const char [4]’ to ‘const Linked_list<std::basic_string<char> >&’ </code></pre> Later later edit: It worked finally, thank you for the ideas: I did just this and it's okay now: <pre><code>Linked_list<Linked_list<string> > l; l[0].add_first("list"); </code></pre> And it works :D. Thanks again ! Neah..actually it doesn't work..

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
