[SOLVED]Weird compile error QObject, QVector

[Alir3z4]

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

if you want the whole source code, it's on the git repo
http://sourceforge.net/p/yodownet/git/..../tree/ (http://sourceforge.net/p/yodownet/git/ci/b7cac562ff0200e0332c1402f6c954473c025e19/tree/)
or simply just clone it

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

QVector<UriStatus> uris() const;
then the project will compiled successfully

thanks

You can't use QObject in QVector. You have to use pointers:
QVector<UriStatus*> uris() const;


...from the documentation
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

Solved!
