That is indeed the answer the OP needed, AFAICT.

Then set the minimum size.

You may set this up dynamically by subclassing the JViewPort's
getPreferredSize() and getMinimumSize() (and maybe getMaximumSize()) and
modifying the returned java.awt.Dimension Object to have its width field
match the desired value.
This might not be the most elegant solution, but it should work and has
the advantage being appliable to all (proper) LayoutManagers.
