How to use splash screen at loading an app for more than 5 sec?

[naufalahad]

Hi All,
I am new to Qt,i am in need of having a splash screen for the login page, where it should be loading for 5 sec and i had seen these forum given below and could not find an exact solution to that one.

I am able to bring the splash screen for 1 sec, but it should be loading for atleast 5 sec with different states and timer for it.

Is there any timer to be given and if there is any sample coding that might help to get through and develop my codings will be much more helpful.

This is the site which i referred:
http://www.developer.nokia.com/Commu...h_screen_in_Qt

Thanks and regards if any one gets me an solution for it.

Use QTimer.

You can write something like this in your MainWindow constructor:

MainWindow::MainWindow(QWidget *parent)
{
...
QTimer::singleShot(5000, this, SLOT(updateCaption()));    
...
}
void MainWindow::updateCaption(void)
{
  // 5 seconds after the app was loaded
}

Sorry to break the party, but why dont you allow the app to start faster on a faster system. The code for this would be like this:

int main(int argc, char *argv[])
{
    QMyApplication a(argc, argv);
    
    QPixmap pixmap(":/backgrounds/rsc/logo.bmp");
    
    int csize;
    
    isFullyUp=false;

    QMainWindow *testForm=new QMainWindow();
    //Get size
    testForm->showFullScreen();
    hsize=testForm->height();
    wsize=testForm->width();
    qDebug() << hsize << wsize;
    testForm->close();
    delete testForm;
    


       qt_OfferIapDialog();


    myAdModule=new InnerActiveAdModule(&a,"Tamoggemon_TypeGun_OVI",120);
    myAdObserver=new QAdObserver(myAdModule, &a);

    QObject::connect(myAdModule, SIGNAL(startReloadAd()), myAdObserver, SLOT(startReloadAd()));
    QObject::connect(myAdModule, SIGNAL(adDataReady()), myAdObserver, SLOT(adDataReady()));
    QObject::connect(myAdModule, SIGNAL(adDataCorrupted()), myAdObserver, SLOT(adDataCorrupted()));
    QObject::connect(myAdModule, SIGNAL(networkError(const QString&)), myAdObserver, SLOT(networkError(const QString&)));

    //myAdModule->setAdProtocolParameter(EIaProtocolParams_Category, "Game");
    myAdModule->setAdProtocolParameter(EIaProtocolParams_DistributionChannelPortal, "551");
    int alpha=myAdModule->requestAd();
    alpha=alpha;
    /*myAdModule->setAdProtocolParameter(EIaProtocolParams_ExternalId, strEid);
    myAdModule->setAdProtocolParameter(EIaProtocolParams_Age, strAge);
    myAdModule->setAdProtocolParameter(EIaProtocolParams_Gender, strGender);
    myAdModule->setAdProtocolParameter(EIaProtocolParams_MobileNumber, strMobileNumber);

    myAdModule->setAdProtocolParameter(EIaProtocolParams_Keywords, strKeywords);
    myAdModule->setAdProtocolParameter(EIaProtocolParams_LocationString, strLocation);
    myAdModule->setAdProtocolParameter(EIaProtocolParams_LocationGps, strLocationGps);*/
