How to create a splash screen with an induced delay

h1. How to create a splash screen with an induced delay.

We have "QSplashScreen":http://doc.qt.nokia.com/latest/qsplashscreen.html which is used to cover up the starting delay of the program. More about splash screen is "here":http://doc.qt.nokia.com/latest/qsplashscreen.html. Some times the programs might be quick enough ,so that the splash screen may not be visible. We may induce some delay to show the splash , as a decoration !

Here in this example, using "QThread":http://doc.qt.nokia.com/latest/qthread.html a delay is induced.

#include <QApplication>
#include <QSplashScreen>
#include <qthread.h>
#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(&amp;mainWin);
 return app.exec();
}

Easy! Happy coding!
