Snippet how to create a splashscreen with opacity and dynamic text:
screencap

Example of main:

  1. QPixmap splashImage(":images/splash.png");
  2. QPixmap splashMask(":images/splashmask.png");
  3.  
  4. customSplashScreen *splash = new customSplashScreen(splashImage);
  5. splash->setMessageRect(QRect::QRect(7, 253, 415, 14), Qt::AlignCenter); // Setting the message position.
  6.  
  7. QFont splashFont;
  8. splashFont.setFamily("Arial");
  9. splashFont.setBold(true);
  10. splashFont.setPixelSize(9);
  11. splashFont.setStretch(125);
  12.  
  13. splash->setFont(splashFont);
  14. splash->setMask(splashMask);
  15. splash->setWindowFlags(Qt::WindowStaysOnTopHint | Qt::SplashScreen);
  16. splash->show();
  17.  
  18. /* To intercept mousclick to hide splash screen. Since the
  19. splash screen is typically displayed before the event loop
  20. has started running, it is necessary to periodically call. */
  21. app.processEvents();
  22.  
  23. splash->showStatusMessage(QObject::tr("Initializing..."));
  24.  
  25. /* Some code here */
  26.  
  27. app.processEvents();
  28.  
  29. splash->showStatusMessage(QObject::tr("Loading something..."));
