Displaying Widget in Dialog from code

[gabor53]

Hi,
I'm trying to display sum_Label in MainWindow but instead it opens a new window and displays the label in the new window.

#include "mainwindow.h"
#include "ui_mainwindow.h"

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

    int num1 = 3;
    int num2 = 5;

add(num1, num2);

}

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

void MainWindow::add(int num1, int num2)
{
    int sum = num1 + num2;
	QString sumvalue = QString::number (sum);


    QLabel *sum_Label = new QLabel();
    sum_Label->setText (sumvalue);

    sum_Label->show ();
	
}

What can I do to display the label in the MainWindow?
Thank you.
