Qt widget to qml

Jerwinprabu

First time, I have created a qt widget for my project. Button, signal and slot, thread everything working properly also I have taken output.

Dialog.h

#include <QDialog>

namespace Ui {
class Dialog;
}

class Dialog : public QDialog
{
    Q_OBJECT

public:
    explicit Dialog(QWidget *parent = 0);
    ~Dialog();

private:
    Ui::Dialog *ui;

public slots:

    void startThread();
    void stopThread();

private slots:

    void on_Autonomous_Mode_2_clicked();
    void on_Manual_Mode_2_clicked();
};

#endif // DIALOG_H

dialog.cpp

#include "dialog.h"
#include "ui_dialog.h"

using namespace std;

Dialog::Dialog(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::Dialog)
{
    ui->setupUi(this);

    cout<<" signal and slot"<<endl;

    startThreadflag = false;
    stopThreadflag = true;
}

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

void Dialog::on_Autonomous_Mode_2_clicked()
{
    this->ui->Start_2->setEnabled(true);
    this->ui->Stop_2->setEnabled(true); 
}

void Dialog::on_Manual_Mode_2_clicked()
{ 
    this->ui->Start_2->setEnabled(false);
    this->ui->Stop_2->setEnabled(false);
}

void  Dialog:: startThread(){

    if(!startThreadflag){

    this->ui->Start_2->setEnabled(false);
    this->ui-> Stop_2->setEnabled(true);

    }
}

void Dialog::on_Start_2_clicked()
{
    startThread();
}

void Dialog:: stopThread(){

    if(!stopThreadflag){

        this->ui->Start_2->setEnabled(true);
        this->ui->Stop_2->setEnabled(false);
    }
}

void Dialog::on_Stop_2_clicked()
{
    stopThread();
}

For creating dashboard purpose I have developed same ui in qml, signal and slot everything connected when I press the button signal and slot connected. But I don't know how to connect the label button, set enabled.

    this->ui->Start_2->setEnabled(true);
    this->ui->Stop_2->setEnabled(false);
