Did you already read the Property Binding chapter of Qt's documentation ?

Can you show the QML code you are using ?

Qml code:

Window
{
visible: true
width: 640
height: 480
title: qsTr("Hello World")

Slider
{
    id: slid
    x: 26
    y: 118
    width: 585
    height: 32
    from:0
    to:100
    stepSize: 1     // here can we give 100ms check for that.
}

Rectangle
{
    id: start
    x: 217
    y: 269
    width: 71
    height: 45
    border.color: "black"

    Text
    {
        id: starttxt
        text: qsTr("Start")
        anchors.centerIn: parent
    }

    MouseArea
    {
        anchors.fill: parent
        onClicked:
        {
            bhushanuser.checkbutton(1)
        }
    }

}

Rectangle
{
    id: stop
    x: 360
    y: 269
    width: 71
    height: 45
    border.color: "black"

    Text
    {
        id: stoptxt
        text: qsTr("stop")
        anchors.centerIn: parent
    }

    MouseArea
    {
        anchors.fill: parent
        onClicked:
        {
            bhushanuser.checkbutton(0)
        }
    }

}

Connections
{
  target: bhushanuser
  onPlay:
  {
   slid.increase()
  }

  onPause:
  {
   slid.decrease()
  }
}

}

main.cpp:-

#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QQmlContext>
#include <QQmlEngine>
#include "slider.h"

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

slider *user = new slider;

QQmlApplicationEngine engine;
QQmlContext *context = engine.rootContext();
context->setContextProperty("bhushanuser",user);

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

return app.exec();

}

slider.cpp

#include "slider.h"
#include <QDebug>

slider::slider(QObject *parent) : QObject(parent)
{

}

void slider::checkbutton(int playpause)
{
if(playpause==1)
{
emit play();
}

if(playpause==0)
{
    emit pause();
}

}

slider.h

#ifndef SLIDER_H
#define SLIDER_H

#include <QObject>

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

signals:
void play();
void pause();
public slots:
void checkbutton(int playpause);
};

#endif // SLIDER_H

As of know, i am doing this thing that after clicking on start button slider will move, i want it to move continue, until i dont pressed stop button.
