@Prasad_Socionext hi,
you can expose your c++ properties to QML : one way is :http://doc.qt.io/qt-5/qtqml-cppintegration-topic.html

This is my main.qml

ApplicationWindow {
    id:start_gui
    visible: true
    width:1200
    height: 800
    title: qsTr("Start GUI")

ui_settings.cpp

#include "ui_settings.h"
#include "qdebug.h"
#include <qqmlengine.h>
#include <QtQuick/QQuickView>
#include <QtQuick/QQuickItem>


Ui_Settings::Ui_Settings(QObject *parent) :
    QObject(parent)
{

}

const int gui_width = 1200;
const int gui_height = 800;

ui_settings.h

#ifndef UI_SETTINGS_H
#define UI_SETTINGS_H
#include <QObject>

class Ui_Settings: public QObject
{
public:
   explicit Ui_Settings(QObject *parent = nullptr);

private:
    Q_INVOKABLE static const int gui_width = 1200;
    Q_INVOKABLE static const int gui_height = 800;
};

#endif // UI_SETTINGS_H

main.cpp

#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <qqmlengine.h>
#include <qqmlcontext.h>
#include <qqml.h>
#include <QStringList>
#include "connect_serial_port.h"
#include "tcpip_client.h"
#include "fileio.h"
#include "ui_settings.h"

int main(int argc, char *argv[])
{
    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
    qmlRegisterType<FileIO, 1>("FileIO", 1, 0, "FileIO");

    QGuiApplication app(argc, argv);

    QQmlApplicationEngine engine;
    Connect_Serial_Port connect_serial_port;
    Tcpip_Client tcpip_client;
    Ui_Settings ui_settings;

    QQmlContext *classContext = engine.rootContext();
    classContext->setContextProperty("connect_serial_port", &connect_serial_port);
    classContext->setContextProperty("tcpip_client", &tcpip_client);
    classContext->setContextProperty("ui_settings",&ui_settings);

    engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
    if (engine.rootObjects().isEmpty())
        return -1;

    connect_serial_port.scan_for_ports();

    return app.exec();
}
