I have an application with a Splash Screen. I need to show the splash screen to appear before the main window appears and wait 3.5 seconds. Once it finished now I need to show the main window.

Here is the code what I have tried,

#include <QApplication>

#include <QGraphicsScene>

#include <QGraphicsView>

#include <QTimer>

#include "game.h"

#include "player.h"

#include <QSplashScreen>

#include <QObject>





Game *game;



int main(int argc, char *argv)



{

    //Splash screen

    QApplication a(argc, argv);

    QSplashScreen *splash = new QSplashScreen;

    splash->setPixmap(QPixmap(":/images/Images/1.JPG"));

    splash->show();



    //main window

    game = new Game();



    QTimer::singleShot(3500, splash, SLOT(close()));



    QTimer::singleShot(3500, game, SLOT(show()));



    game->displayHome();

    return a.exec();

}

Game Class

Game::Game(QWidget *parent)

{



    scene = new QGraphicsScene();

    scene->setSceneRect(0,0,800,600);

    setBackgroundBrush(QBrush(QImage("img.png")));



    setScene(scene);

    setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);

    setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);

    setFixedSize(800,600);



    show();

     qDebug() << "yoyoyoy";



     score = new Score();

    health = new Health();





    connect(this->health,SIGNAL(crash()),this,SLOT(gameover3()));

}



void Game::displayHome()

{

    logo = new Logo();

    scene->addItem(logo);



    playButton = new Menubuttons(QString("Play"));

    int bxPos = this->width()/2 - playButton->boundingRect().width()/2;

    int byPos = 275;

    playButton->setPos(bxPos,byPos);

    connect(playButton,SIGNAL(clicked()),this,SLOT(startGame()));

    scene->addItem(playButton);



    instructions = new Menubuttons(QString("Instructions"));

    int axPos = this->width()/2 - instructions->boundingRect().width()/2;

    int ayPos = 350;

    instructions->setPos(axPos,ayPos);

    connect(instructions,SIGNAL(clicked()),this,SLOT(instruct()));

    scene->addItem(instructions);



    quitButton = new Menubuttons(QString("Quit"));

    int qxPos = this->width()/2 - quitButton->boundingRect().width()/2;

    int qyPos = 425;

    quitButton->setPos(qxPos,qyPos);

    connect(quitButton,SIGNAL(clicked()),this,SLOT(close()));

    scene->addItem(quitButton);



    scene->removeItem(inst);

}

But it appears both at the same time. How can I fix that?

The behavior you describe is not reproduced by the complete example below

#include <QtWidgets/QApplication>

#include <qmainwindow.h>

#include <qwidget.h>

#include <qtimer.h>

#include <qsplashscreen.h>



QMainWindow* game;



int main(int argc, char *argv)

{

    QApplication a(argc, argv);



    QSplashScreen *splash = new QSplashScreen;

    splash->setPixmap(QPixmap(":/StackOverflow/SplashScreen"));

    splash->show();



    game = new QMainWindow();       



    QTimer::singleShot(3500, splash, SLOT(close()));

    QTimer::singleShot(3500, game, SLOT(show()));



    return a.exec();

}

Running this displays a splash screen for 3.5 seconds followed by the main window. The issue may be your implementation for the Game class or the member function displayHome().

Edit

After your edit with the Game class definition and implementation it is clear the problem is calling show() at the end of the Game::Game() constructor. This causes game to display immediately upon construction, the subsequent call to show() in QTimer::singleShot(3500, game, SLOT(show())) is redundant upon the already visible object. To fix this simply remove show() from the Game constructor, i.e. it should be

Game::Game(QWidget *parent)

{

    scene = new QGraphicsScene();

    scene->setSceneRect(0, 0, 800, 600);

    setBackgroundBrush(QBrush(QImage("img.png")));



    setScene(scene);

    setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);

    setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);

    setFixedSize(800, 600);

}
