How to use multiple focus setFocusItem

Caique Moura

Hey, I'm using keyPressEvent to build a space invader's game. My problem is because I want to focus 2 items on Dialog, I just can focus one of them, what should I use to focus 2 or more items?
//
item3-> setFlag(QGraphicsItem::ItemIsFocusable);
item4-> setFlag(QGraphicsItem::ItemIsFocusable);
scene->setFocusItem(item3);
scene->setFocusItem(item4);
// principal code

#include "dialog.h"
#include "ui_dialog.h"
#include"minhanave.h"
#include"atirador.h"
#include"combatente.h"
#include<QGraphicsItem>
#include "bala.h"
Dialog::Dialog(QWidget *parent) :
QDialog(parent),
ui(new Ui::Dialog)
{
ui->setupUi(this);

scene = new QGraphicsScene(this);
ui->graphicsView->setScene(scene);
ui->graphicsView->setRenderHint(QPainter:: Antialiasing);
// caixa delimitadora
scene->setSceneRect(-200,-200,300,300);

QPen mypen = QPen (Qt::black);

QLineF TopLine(scene->sceneRect().topLeft(),scene->sceneRect().topRight());
QLineF LeftLine(scene->sceneRect().topLeft(),scene->sceneRect().bottomLeft());
QLineF RightLine(scene->sceneRect().topRight(),scene->sceneRect().bottomRight());
QLineF BottomLine(scene->sceneRect().bottomLeft(),scene->sceneRect().bottomRight());

scene->addLine(TopLine,mypen);
scene->addLine(LeftLine,mypen);
scene->addLine(RightLine,mypen);
scene->addLine(BottomLine,mypen);
// caixa delimitadora

//add Item
    MinhaNave *item = new MinhaNave();
    //Atirador *item2 = new Atirador();
    Combatente *item3 = new Combatente();
    Bala *item4 = new Bala();
    scene->addItem(item);
    //scene->addItem(item2);
    scene->addItem(item3);
    scene->addItem(item4);
// make rect focusable
item3-> setFlag(QGraphicsItem::ItemIsFocusable);
item4-> setFlag(QGraphicsItem::ItemIsFocusable);
scene->setFocusItem(item3);
scene->setFocusItem(item4);

//add Item
timer = new QTimer(this);
connect(timer,SIGNAL(timeout()), scene,SLOT(advance()));
//celera jesus
timer->start(100);

}

Dialog::~Dialog()
{
delete ui;
}

Hi and welcome to devnet,

What is your goal exactly with these two objects ?
