#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QSettings>
#include <QDebug>

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    QSettings * qsettings = new QSettings(":/config.ini",QSettings::IniFormat);
    bool status = qsettings->value("preview","").toBool();
    qDebug() << status;

}

MainWindow::~MainWindow()
{
    delete ui;
}

Solution

  • This works like a charm for me:

    main.qrc

    <!DOCTYPE RCC><RCC version="1.0">
    <qresource>
        <file>config.ini</file>
    </qresource>
    </RCC>
    

    main.cpp

    #include <QSettings>
    #include <QDebug>
    
    int main()
    {
        QSettings settings(":/config.ini", QSettings::IniFormat);
        qDebug() << settings.value("preview", false).toBool();
        qDebug() << settings.value("non-existent", false).toBool();
        return 0;
    }
    

    main.pro

    TEMPLATE = app
    TARGET = main
    QT = core
    SOURCES += main.cpp
    RESOURCES += main.qrc
    

    Build and Run

    qmake && make && ./main
    

    Output

    true
    false
