Class DefaultListRenderer

java.lang.Object
  org.jdesktop.swingx.renderer.AbstractRenderer
      org.jdesktop.swingx.renderer.DefaultListRenderer

All Implemented Interfaces:

Serializable, ListCellRenderer, StringValue, RolloverRenderer

public class DefaultListRenderer
extends AbstractRenderer
implements ListCellRenderer

Adapter to glue SwingX renderer support to core API. It has convenience constructors to create a LabelProvider, optionally configured with a StringValue and horizontal alignment. Typically, client code does not interact with this class except at instantiation time.

Note: core DefaultListCellRenderer shows either an icon or the element's toString representation, depending on whether or not the given value is of type icon or implementors. This renderer's empty/null provider constructor takes care of configuring the default provider with a converter which mimics that behaviour. When instantiating this renderer with any of the constructors which have converters as parameters, it's up to the client code to supply the appropriate converter, if needed:

 StringValue sv = new StringValue() {
 
     public String getString(Object value) {
         if (value instanceof Icon) {
             return "";
         }
         return StringValue.TO_STRING.getString(value);
     }
 
 };
 StringValue lv = new MappedValue(sv, IconValue.ICON);
 listRenderer = new DefaultListRenderer(lv, alignment);

Constructor Detail

DefaultListRenderer

public DefaultListRenderer()

Instantiates a default list renderer with the default component provider.

DefaultListRenderer

public DefaultListRenderer(ComponentProvider componentProvider)

Instantiates a ListCellRenderer with the given ComponentProvider. If the provider is null, creates and uses a default. The default provider is of type LabelProvider

Note: the default provider is configured with a custom StringValue which behaves exactly as core DefaultListCellRenderer: depending on whether or not given value is of type icon or implementors, it shows either the icon or the element's toString.

Parameters:

componentProvider - the provider of the configured component to use for cell rendering

DefaultListRenderer

public DefaultListRenderer(StringValue converter)

Instantiates a default table renderer with a default component controller using the given converter.

PENDING JW: how to guarantee core consistent icon handling? Leave to client code?

Parameters:

converter - the converter to use for mapping the content value to a String representation.

DefaultListRenderer

public DefaultListRenderer(StringValue converter,
                           int alignment)

Instantiates a default list renderer with a default component controller using the given converter and horizontal alignment. PENDING JW: how to guarantee core consistent icon handling? Leave to client code?

Parameters:

converter - the converter to use for mapping the content value to a String representation.

alignment - the horizontal alignment.

DefaultListRenderer

public DefaultListRenderer(StringValue stringValue,
                           IconValue iconValue)

Instantiates a default list renderer with default component provider using both converters.

Parameters:

stringValue - the converter to use for the string representation

iconValue - the converter to use for the icon representation

DefaultListRenderer

public DefaultListRenderer(StringValue stringValue,
                           IconValue iconValue,
                           int alignment)

Instantiates a default list renderer with default component provider using both converters and the given alignment.

Parameters:

stringValue - the converter to use for the string representation

iconValue - the converter to use for the icon representation

alignment - the rendering component's horizontal alignment

getListCellRendererComponent

public Component getListCellRendererComponent(JList list,
                                              Object value,
                                              int index,
                                              boolean isSelected,
                                              boolean cellHasFocus)

Returns a configured component, appropriate to render the given list cell.

Specified by:

getListCellRendererComponent in interface ListCellRenderer

Parameters:

list - the JList to render on

value - the value to assign to the cell

isSelected - true if cell is selected

cellHasFocus - true if cell has focus

index - the row index (in view coordinates) of the cell to render

Returns:

a component to render the given list cell.
