How to dynamicly resize field's label in a form layout ?

[GuA]

I have a form that contains fields with labels that can dynamicly be changed.
I'm using the TextMetrics class to get the max width needed for the labels, but I can't find a way to reflect the


formLayout.setLabelWidth(computedSize); into the panel.

What is the way to have the label to adapt to the new size in the view ?
