JList setMimimumSize() inside a JScrollPane

Question

I have a JScrollPane which has a JList inside;

    instructionsScrollPane = new JScrollPane(instructionList);

The JScrollPane is itself in a JPanel using BorderLayout;

    panel.add(instructionsScrollPane, BorderLayout.WEST);

Now, I am trying to stop the list/scrollpane going below a a certain minimum size when the window is resized, except JScrollPane can't have minimum size set, and the list is inside the JScrollPane which can't have a layoutManager. So I am unable to set the minimum size of the JList without a layoutManager...

Now, I think I could have the JScrollPane/JList centered using BorderLayout inside another JPanel (which I would then set a minimum size of) inside this the current panel... but that seems messy. Does anyone know of a better way to size ScrollPanes?

I know there is probably a solution using a different layoutManager, but I am already committed to using BorderLayout at this point.

for JList is very easy, simple to set initial coordinates, returns expected Dimension for LayoutManager, there are two methods implemented in API

• JList.setPrototypeCellValue

  and/or if really needed to restrict 2nd dimension

• JList.setVisibleRowCount
