Snippet how to create a splashscreen with opacity and dynamic text.
In main.cpp:

customSplashScreen* splash = new customSplashScreen(splashImage);
splash->setMessageRect(QRect::QRect(7, 253, 415, 14), Qt::AlignCenter); // Setting the message position.
QFont splashFont;
splashFont.setFamily("Arial");
splashFont.setBold(true);
splashFont.setPixelSize(9);
splashFont.setStretch(125);
splash->setFont(splashFont);
splash->setMask(splashMask);
splash->setWindowFlags(Qt::WindowStaysOnTopHint | Qt::SplashScreen);
splash->show();
/* To intercept mousclick to hide splash screen. Since the
splash screen is typically displayed before the event loop
has started running, it is necessary to periodically call. */
