public Component getListCellRendererComponent(JList<?> list, Object value, int index, boolean isSelected, boolean cellHasFocus) Implements javax.swing.ListCellRenderer.getListCellRendererComponent. Doc from javax.swing.ListCellRenderer.getListCellRendererComponent. Return a component that has been configured to display the specified value. That component's `paint` method is then called to "render" the cell. If it is necessary to compute the dimensions of a list because the list cells do not have a fixed size, this method is called to generate a component on which `getPreferredSize` can be invoked.
