Splash screen in not showing in exec file

vsukhwal

Hello there,

I have created a splash screen which is shown on the launch of my project when I run my application in qt creator. However, when I try to click on the app.exe file in the release folder, my application launches without showing the splash screen. Can you please tell me why is this happening?

I tried building my application several times and the behavior stays the same.

Thanks,
Vidushi

Hi! Please provide a minimal working example.

Also, I have added all the images in the resources folder. So that is also checked. Following is my code

#include "home.h"
#include "splashscreen.h"
#include <QApplication>
#include <QStyleFactory>
#include <QDebug>
#include "QsLog.h"
#include "QsLogDest.h"
#include "QsLogWindow.h"
#include <QDir>
#include <QSplashScreen>
#include <QTimer>
#include <QtNetwork>
#include <QUrl>
#include <QUrlQuery>
#include <QJsonDocument>
#include <QJsonParseError>
#include <QJsonArray>
#include <string>
#include <QRect>

void sendRequest();

int main(int argc, char *argv[])
{
QApplication a(argc, argv);

//set the application icon and splash screen
a.setWindowIcon(QIcon("./img/icon_2.png"));

QPixmap splashImage("./img/icon_3.png");

splashscreen* splash = new splashscreen(splashImage);


QFont splashFont;
splashFont.setFamily("Arial");
splashFont.setBold(true);
splashFont.setPixelSize(11);
splashFont.setStretch(125);

splash->setFont(splashFont);

//    splash->setMask(splashMask);
splash->setWindowFlags(Qt::WindowStaysOnTopHint | Qt::SplashScreen);
splash->show();

a.processEvents();

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

sendRequest();

a.processEvents();

splash->showStatusMessage(QObject::tr("Getting user permissions and roles…"));

Home w;
w.ui->tabWidget->setStyle(QStyleFactory::create("Fusion"));

QTimer::singleShot(2500,splash,SLOT(close()));
QTimer::singleShot(2500,&w,SLOT(show()));
//    w.show();

return a.exec();

}

void sendRequest()
{

// http call

}

what is splash? it's undeclared identifier in main
If it's a QSplashScreen and you are setting a pixmap on it, make sure you deploy the imageformats plugin to handle the image format. for example, if you set a jpg as splash you have to deploy the qjpeg.dll

Hi,

To add to @VRonin your path is relative so you should also have the files in the proper place when you deploy your application. Or since it's a splash screen, you might want to embed it using Qt's resource system.

@SGaist : I have embedded it in the resources file as well explicitly and added a relative path. I can see my splash screen image in the img.qrc. Is there any other folder i need to put my file?

@VRonin: Will i also have to include a dll associated to png image? splash is declared as an instance of splashcreen class. code of that class is as follows:

#include "splashscreen.h"
#include <QRect>
#define COPYRIGHT_PREFIX 0xA9

splashscreen::splashscreen(const QPixmap& pixmap)
{
    QSplashScreen::setPixmap(pixmap);
}

splashscreen::~splashscreen()
{
}

void splashscreen::drawContents(QPainter *painter)
{
    QPixmap textPix = QSplashScreen::pixmap();
    painter->setPen(this->color);
    QString copyrightString;
    copyrightString.sprintf( "%c", COPYRIGHT_PREFIX);

    painter->drawText(QRect(200,253,415, 200), Qt::AlignLeft, "Version:  0.1\n\nCopyright"+copyrightString+" 2017-2018 Intel Corporation\n\nApplication suite:  METIS Client\n\n"+this->message);
//    painter->drawText(QRect(200,453,415, 200), Qt::AlignLeft, this->message);

//    painter->drawText(this->rect, this->alignement, this->message);
}

void splashscreen::showStatusMessage(const QString &message, const QColor &color)
{
    this->message = message;
    this->color = color;
    this->showMessage(this->message, this->alignement, this->color);
}

void splashscreen::setMessageRect(QRect rect, int alignement)
{
    this->rect = rect;
    this->alignement = alignement;
}

IIRC png is a builtin format.

You still need to pass the correct path to your embedded file. Did you check that ?

vsukhwal

And it works! Path issue. thanks guys!

You're welcome !

Hey guys,

I was able to see the icons and splash screen when i launched my application using the .exe file in the release folder finally. However, I faced another issue when I packed my file for distribution (using innosetup). When I installed the packaged file, I was not able to see the icon I created on the desktop icon and the task bar(once open).

This problem was not there before the packaging.

Did you follow that guide ?
