Using Vectors with Qt

Question

I seem to be having an issue using basic vectors in Qt, where I keep getting a compile error. The exact information will be posted below:

Code snippet:

....
#include <QVector>
#include <QString>

QVector<QString> vector;
vector.append("sometext");

Error message:

'vector' does not name a type

This error appears for any piece of code that directly pertains to the created vector, not just the append function. Any insight to what I am doing wrong would be appreciated. The vector exists. I've tested it by initializing all of it's elements using one item and accessing it in other parts of the program.

The code is fine. The cause is somewhere else. – Pavel Strakhov Nov 26 '13 at 09:57 — Pavel Strakhov, Nov 26 '13 at 09:57
Maybe use a new name other than `vector`? – WiSaGaN Nov 26 '13 at 10:17 — WiSaGaN, Nov 26 '13 at 10:17

#include <QVector>
#include <QString>

QVector<QString> vector;
vector.append("sometext");

If this is your real code, then you are doing the append outside of any function, which you can't do in c++, and which will cause the exact compilation error you mentioned:

This is precisely the case. My professor neglected to express something so simple. I will accept this answer as soon as this website enables me to do so. – Ruiz Nov 26 '13 at 10:03
Fix: `QVector vector(1, "sometext");`. If you need more values, you need C++11: `QVector vector { "one", "two", "three" };` – MSalters Nov 26 '13 at 12:37
