I solved it by trying few things Here's the explanation of what i did
I've split my function in two. The first one put the element in a QList
and the second one shuffles it.
/**
* @brief MenuQuestionnary::assembleQuiz
* @param list
* Asseble a quiz in the Qlist and then ask shuffle to shuffle it...
*/
void MenuQuestionnary::assembleQuiz(QList<Question> &list){
for(int i = 0; i < spinBoxNumberOfQuestion->value(); ++i){
int rand = qrand() * maximumNumberOfQuestionAvailable;
Question newQuestion(rand);
list.append(newQuestion);
}
shuffleQuiz(list);
}
/**
* Method Shuffle
* equivalent to shuffling a deck of cards: we take a random one, move it to be the last one,
* then do it again enough times to have statistically touched every card.
*/
void MenuQuestionnary::shuffleQuiz(QList<Question> &list){
int iters = list.size() * list.size();
for (int i = 0; i < iters; ++i){
int rand = qrand() * list.size();
list.append(list[rand]);
list.removeAt(rand);
}
}
Thanks for the help though.
