Label does not resize with resizeEvent

[ronyNS]

lbl = new QLabel( ui->centralWidget);
    lbl->setStyleSheet("Background-color:pink");

How do i resize this label using resizeEvent . When i put this code in void Mainwindow :: resizeEvent(QreseizeEvent *evt) ; it stays the same. The size does not change.

Please give me a proper explanation about resize event.

Thank you.

resizeEvent

http://doc.qt.io/qt-5/qwidget.html#resizeEvent

Its called when mainwindow change size.

To size a qlabel
you do
lbl->resize(x,y)
or
lbl->setGeometry(0,0, event->size().width(), event->size().height());
to use the mainwindow values

It fits the window size , but does not resize when i maximize the window

My code

Void MainWindow :: resizeEvent(QResizeEvent *event)
{
lbl = new QLabel (ui->centralWidget);
Int x = MainWindow::size().height();
Int y = MainWindow::size().width();
lbl->resize(x,y);

MainWindow::resizeEvent(evt);
}

@ronyNS Why not use a layout for that? I just tried: added a label to main window and set the layout in main window: label is resized even if I maximize window.
