Description
Widgets can retain old minimum and maximum size constraints. Setting a new size constraint will not remove minimum and maximum values from another one.
The qlayout.cpp has mentions regarding that and an example can be tst_qlayout.cpp
void clearConstraintAndResize(QSize sz, Qt::Orientations o = Qt::Horizontal | Qt::Vertical)
{
if (o == (Qt::Horizontal | Qt::Vertical))
setSizeConstraint(QLayout::SizeConstraint::SetNoConstraint);
else if (o == Qt::Vertical)
setVerticalSizeConstraint(QLayout::SizeConstraint::SetNoConstraint);
else if (o == Qt::Horizontal)
setHorizontalSizeConstraint(QLayout::SizeConstraint::SetNoConstraint); parentWidget()->setMinimumSize(0, 0); // <== ***** Should NOT be needed ****
parentWidget()->setMaximumSize(QWIDGETSIZE_MAX, QWIDGETSIZE_MAX);
parentWidget()->resize(sz);
activate();
}
