Description

Code

#include <QDesktopServices>
#include <QFile>
#include <QGuiApplication>
#include <QImage>
#include <QStandardPaths>
#include <QUrl>

int main(int argc, char *argv[])
{
    QGuiApplication app(argc, argv);

    QFile imgFile(QStandardPaths::writableLocation(QStandardPaths::DocumentsLocation) + "/example.png");
    auto imgUrl = QUrl::fromLocalFile(imgFile.fileName());

    QImage img(100, 100, QImage::Format_RGB32);
    img.fill(Qt::green);

    if (imgFile.open(QIODevice::WriteOnly))
    {
        qDebug() << "Saving image to" << imgUrl;
        qDebug() << img.save(&imgFile);
        imgFile.close();
    }
    else
        qWarning() << "Failed to open example.png for writing!";

    qDebug() << "Attempting to launch external viewer...";
    QDesktopServices::openUrl(imgUrl);

    return app.exec();
}
