FYI: DefaultListCellRenderer.getListCellRendererComponent() test

[Mark Wielaard <mark at klomp dot org>]

Hi,

Here is a simple test for
DefaultListCellRenderer.getListCellRendererComponent() to make sure a
Component that returns a valid Dimension when getPreferredSize() is
called for some random cell values.

       * gnu/testlet/javax/swing/DefaultListCellRenderer/
       getListCellRendererComponent.java: New test.

Committed,

Mark
