What is missing from what you propose is the notion of column or row:
ColumnResizer lets you limit resizing to one column only so for example if
you have two 3-columns QGridLayouts stacked on top of each other then you
can link the first column widths while leaving each layout decide how they
want to size the 2 other columns.
What about this instead?
QLayout::linkDimension(QLayout *other, int index, Qt::Orientation
orientation = Qt::Vertical);
