QLabel associated to a PushButton doesn't appears

I'm trying to build a QLabel that I'd like to appear when I press a QPushButton; code is simple:

    void Mod28::on_pushButton_clicked()
    {
       AddItem();
    }
    void Mod28::AddItem()
    {
       QLabel *label_n = new QLabel(this);
       label_n->setObjectName(QStringLiteral("label_n"));
       label_n->setGeometry(QRect(20, DimVert, 25, 17));
       label_n->setFrameShape(QFrame::Box);
       label_n->setNum(ItemCounter);
     }

Nothing appears. Instead, if I put AddItem() inside the following:

    Mod28::Mod28(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::Mod28)
    {
        ui->setupUi(this);
        AddItem(); // here, for example, is ok !!!!
    }

How can I solve? I need a QLabel appearing when I press the button.

Try to call label_n->show (); label_n->raise(); after.

Add your label to the widget that you want to show in it.

for example this line add lable to centralWidget layout:

ui->centralWidget->layout()->addWidget(label_n);

your function:

void Mod28::AddItem()
{
   QLabel *label_n = new QLabel(this);
   //
   //
   //
   ui->centralWidget->layout()->addWidget(label_n);
}
