I want to take list widget dynamically and take multiple push button inside listwidget dynamically

amarism

I am taking the list widget dynamically as

 QListWidget *widgetOnTheTop = new QListWidgetWidget(this);
      widgetOnTheTop->setGeometry(100,30,100,105);
      widgetOnTheTop->show();

But i am not able to take button inside the list widget . I will try to use this code

 QVBoxLayout *layout=new QVBoxLayout();
      for (int i = 0; i < 4; ++i){
          for(int j=0;j<4;j++){
            QPushButton *button = new QPushButton();
            button->setText(QString::number(i));
            layout->addWidget(button);
            button->show();
          }
      }
    widgetOnTheTop->setLayout(layout);

But nothing will happen.
Also I want to know is it possible to add button inside the listwidget dynamically.

Any help is considerable.
Thank you in advance

@amarism
You are trying to use setLayout on a whole QListWidget. I imagine that is not the usage. You should be creating QListWidgetItems and then QListWidget::insertItem() to populate it with items.

That's what a QListWidget is for. It's a combo/list box of items. It wouldn't surprise me if you cannot put buttons in items, I don't know. I don't understand just what you are trying to achieve. It might help if you explained what you are expecting to achieve/it to look like.

@JonB I have a comboBox and onclick of combo Box i want to create a dynamic widget were they have multiple buttons.
This whole work is using for showing the slipt screen of QOpenGLWidget like (1x1,1x2,2x1,4x5..... so on). I am taken the same example from RADint viewer. I am also attaching the image view of what i want to do in my project.
