Help with Uno game

[nootey]

I'm trying to make the game UNO for my school assigment, i'm quite new to visual programming, we haven't really taken it yet at school (lol) but i have to make the game in about an month and so far i've made a deck that suffles the random cards and a hand, which contains 7 cards from said deck. But i can't seem to move the cards in hand to the lower end of the "playfield". I've tried setPos, moveBy with no succes. I'll post the code bellow

UnoCard.h:

#ifndef UNOCARD_H
#define UNOCARD_H

#include<QGraphicsItem>
#include <QString>
#include <QObject>

class UnoCard: public QObject, public QGraphicsRectItem
{ Q_OBJECT
public:
QString number;
QString color;


UnoCard(QString num, QString c);
};


#endif // UNOCARD_H

UnoDeck.h:

#ifndef UNODECK_H
#define UNODECK_H

#include "unocard.h"
#include <QList>

class UnoDeck
{public:
QList<UnoCard *> deck;
UnoDeck();
void init_deck();
void izpis();
void shuffle();
void kolikokrat();
void polni(QList <UnoCard> &yeah, int hand);
};

#endif // UNODECK_H

UnoCard.cpp:

#include "unocard.h"
#include <Qbrush>
#include <QGraphicsTextItem>
#include <QTextEdit>
#include <QGraphicsEllipseItem>
#include <QObject>

UnoCard::UnoCard(QString number, QString color)
{

this->setRect(0,0,220,300);
this->setBrush(QBrush(QColor(color)));

QGraphicsEllipseItem *ecl = new QGraphicsEllipseItem(this);
ecl->setRect(80,-40,170,270);
ecl->setBrush(Qt::white);
ecl->setRotation(25);
QGraphicsTextItem *txt =new QGraphicsTextItem(this);
txt->setDefaultTextColor(color);
txt->setPlainText(number);
txt->setPos(35,35);
txt->setScale(10.5);



}

UnoDeck.cpp:

#include "unodeck.h"
#include "unocard.h"
#include <ctime>
#include <cstdlib>


UnoDeck::UnoDeck()
{QString color;
int st=0;

for(int i=0; i < 20; i++)
{if(i%10==0)st=0;

for(int j=0; j < 4;j++)
{
switch(j){
case 0: color="blue"; break;
case 1: color="green"; break;
case 2: color="yellow"; break;
case 3: color="red"; break;
default: color="black";
}
UnoCard *card = new UnoCard(QString::number(st),color);
UnoDeck::deck.append(card);
}st++;
}
}
void UnoDeck::shuffle()
{
srand(time(0));
std::random_shuffle(deck.begin(), deck.end());
}

main.cpp:

#include <QApplication>
#include <QGraphicsScene>
#include "unocard.h"
#include "unodeck.h"
#include <QGraphicsView>
#include <QTextEdit>
#include <QList>
#include <QString>
#include <QObject>
#include <ctime>
#include <cstdlib>
#include <QList>






int main(int argc, char *argv[])
{

QApplication a(argc, argv);
//ustvari sceno
QGraphicsScene *scene = new QGraphicsScene();
//ustvari deck
UnoDeck *ez = new UnoDeck();
ez->shuffle();
//doda deck na sceno


QList <UnoCard *> hand;
for(int i=0;i<7;i++)
{
hand.append(ez->deck.last());
ez->deck.pop_back();

}
hand.first()->moveBy(100,100);
scene->addItem(hand.first());
