[SOLVED]Weird compile error QObject, QVector

Hi
I have a weird compile error which is related to QVector :|
here's the error

Code:

class source

Code:

---

#ifndef FILEINFO_H
#define FILEINFO_H
 
#include <QObject>
#include <QString>
#include <QVector>
#include "uristatus.h"
 
class FileInfo : public QObject
{
    Q_OBJECT
public:
    explicit FileInfo(QObject *parent = 0);
 
    void setIndex(const QString &index);
    void setPath(const QString &path);
    void setLength(const QString &length);
    void setSelected(const QString &selected);
    void setUris(const QVector<UriStatus> &uris);
 
    QString index() const;
    QString path() const;
    QString length() const;
    QString selected() const;
    QVector<UriStatus> uris() const;
 
private:
    QString _index;
    QString _path;
    QString _length;
    QString _selected;
    QVector<UriStatus> _uris;
};
 
#endif // FILEINFO_H

if you want the whole source code, it's on the git repo
http://sourceforge.net/p/yodownet/git/..../tree/
or simply just clone it

Code:

---

git clone git://git.code.sf.net/p/yodownet/git yodownet-git

---

i really get confused by this error and i tried alot of ways, but when i comment declaration/definition of this

Code:

---

QVector<UriStatus> uris() const;

---

then the project will compiled successfully

thanks

You can't use QObject in QVector. You have to use pointers:

Code:

---

QVector<UriStatus*> uris() const;

---

...from the documentation

Quote:

---

QVector's value type must be an assignable data type. This covers most data types that are commonly used, but the compiler won't let you, for example, store a QWidget as a value; instead, store a QWidget *. A few functions have additional requirements; for example, indexOf() and lastIndexOf() expect the value type to support operator==(). These requirements are documented on a per-function basis.

Hmmmm,
Thank you
Your Quote from the qt documentation is the main point
diff
Solved!
