Method sizeConstraintsChanged

src/qt/qcustomplot.cpp:3762–3768

! Subclasses call this method to report changed (minimum/maximum) size constraints. If the parent of this layout is again a QCPLayout, forwards the call to the parent's \ref sizeConstraintsChanged. If the parent is a QWidget (i.e. is the \ref QCustomPlot::plotLayout of QCustomPlot), calls QWidget::updateGeometry, so if the QCustomPlot widget is inside a Qt QLayout, it may update itsel

  it may update itself and resize cells accordingly.
