QGridLayout setRowStretch

[GrahamLa]

Hi
I am having trouble setting a row stretch
This snippet shows what I have attempted - it is obviosly part of a larger program, but I woujld be grateful if soemone could suggest any reason why the row stretch is not honoured.

    QGridLayout *pxLayout = new QGridLayout();
    pxLayout->addLayout(pxFilterLayout,   0, 0);
    pxLayout->addLayout(pxTableLayout, 1, 0);
    pxLayout->addWidget(pxDetailsLabel, 2, 0);
    pxLayout->addWidget(m_pxDetailsText, 3, 0);

	pxLayout->setRowStretch(0, 10);
	pxLayout->setRowStretch(1, 80);
	pxLayout->setRowStretch(2, 10);

@GrahamLa hi. your problem is not clear to me. But when I run into a problem about QGridLayout I just check the qt calculator example
( https://doc.qt.io/qt-5/qtwidgets-widgets-calculator-example.html). it is very helpful to me. I think its better to share the whole code and please be more clear.
