Snippet how to create a splashscreen with opacity and dynamic text.

In main.cpp:

QPixmap splashImage(":images/splash.png"); QPixmap splashMask(":images/splashmask.png");

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. */ app.processEvents();

splash->showStatusMessage(QObject::tr("Initializing…"));

/* Some code here */

app.processEvents();

splash->showStatusMessage(QObject::tr("Loading something…"));

customSplashScreen.h:

1. ifndef CUSTOMSPLASHSCREEN_H
2. define CUSTOMSPLASHSCREEN_H

1. include <QSplashScreen>
2. include <QPainter>

class customSplashScreen : public QSplashScreen { public:

   customSplashScreen(const QPixmap& pixmap);
   ~customSplashScreen();
   virtual void drawContents(QPainter *painter);
   void showStatusMessage(const QString &message, const QColor &color = Qt::black);
   void setMessageRect(QRect rect, int alignment = Qt::AlignLeft);

private:

   QString message;
   int alignement;
   QColor color;
   QRect rect;

};

1. endif // CUSTOMSPLASHSCREEN_H

customSplashScreen.cpp:

1. include "customSplashScreen.h"

customSplashScreen::customSplashScreen(const QPixmap& pixmap) {

  QSplashScreen::setPixmap(pixmap);

};

customSplashScreen::~customSplashScreen() { };

void customSplashScreen::drawContents(QPainter *painter) {

   QPixmap textPix = QSplashScreen::pixmap();
   painter->setPen(this->color);
   painter->drawText(this->rect, this->alignement, this->message);

};

void customSplashScreen::showStatusMessage(const QString &message, const QColor &color) {

   this->message = message;
   this->color = color;
   this->showMessage(this->message, this->alignement, this->color);

};

void customSplashScreen::setMessageRect(QRect rect, int alignement) {

   this->rect = rect;
   this->alignement = alignement;

};
