Unsolved QList<QList<QSqlRecord>>

[shahriar25]

Hi,
I wanted to have a list of list of sqlRecords so I did this:

QList<QList<QSqlRecord>> list;

but when I do this:

list[i].append(another list of records);

the program crashes and when I do this:

list.at(i).append(another list of records);

I get this error:

error: passing 'const QList<QSqlRecord>' as 'this' argument discards qualifiers [-fpermissive]
m_records.at(i).append(m_sqlTable->records());
^

What should I do?

@shahriar25
That is because of const T &QList::at(int i) const. You are trying to mdify a const reference to the element.

This should work.
list[i].append(another list of records);

BTW It should be a compile error and not a crash of your application.

Hi I did this and the problem was solved. it was really a silly mistake of mine and I,m sorry. you were right

    m_records.append(QList<QSqlRecord>());
    m_records[i].append(m_sqlTable->records());
