Splash screen with an induced delay

Here is an easy implementation of Splash screen with an induced delay using QThread.

#include "mainwindow.h"

class I : public QThread

{

public:

        static void sleep(unsigned long secs) {

                QThread::sleep(secs);

        }

};

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

{

    QApplication app(argc, argv);

    QPixmap pixmap("splash.jpg");

    QSplashScreen splash(pixmap);

    splash.show();

    MainWindow mainWin;

    mainWin.setWindowTitle("Application");

    I::sleep(5);               // splash is shown for 5 seconds

    mainWin.showMaximized();

    splash.finish(&mainWin);

    return app.exec();

}
