# Class MultiList

java.lang.Object
com.codename1.ui.Component
com.codename1.ui.List
com.codename1.ui.list.MultiList

All Implemented Interfaces:
  `Animation, Editable, ActionSource, StyleListener`

public class MultiList extends List

A list with a `com.codename1.components.MultiButton` renderer, notice that we strongly discourage usage of lists.. This simplifies the process of working with the list and its model as the renderer comes pre-configured for common use cases.

    public void showForm() {
      Form hi = new Form("MultiList", new BorderLayout());

      int mm = Display.getInstance().convertToPixels(3);
      EncodedImage placeholder = EncodedImage.createFromImage(Image.createImage(mm * 3, mm * 4, 0), false);
      Image icon1 = URLImage.createToStorage(placeholder, "icon1", "http://www.georgerrmartin.com/wp-content/uploads/2013/03/GOTMTI2.jpg");
      Image icon2 = URLImage.createToStorage(placeholder, "icon2", "http://www.georgerrmartin.com/wp-content/uploads/2012/08/clashofkings.jpg");
      Image icon3 = URLImage.createToStorage(placeholder, "icon3", "http://www.georgerrmartin.com/wp-content/uploads/2013/03/stormswordsMTI.jpg");
      Image icon4 = URLImage.createToStorage(placeholder, "icon4", "http://www.georgerrmartin.com/wp-content/uploads/2012/08/feastforcrows.jpg");
      Image icon5 = URLImage.createToStorage(placeholder, "icon5", "http://georgerrmartin.com/gallery/art/dragons05.jpg");

      ArrayList> data = new ArrayList<>();
      data.add(createListEntry("A Game of Thrones", "1996", icon1));
      data.add(createListEntry("A Clash Of Kings", "1998", icon2));

      data.add(createListEntry("The Winds of Winter", "2016 (please, please, please)", placeholder));
      data.add(createListEntry("A Dream of Spring", "Ugh", placeholder));

      DefaultListModel> model = new DefaultListModel<>(data);
      MultiList ml = new MultiList(model);
      hi.add(BorderLayout.CENTER, ml);
      hi.show();
    }

    private Map createListEntry(String name, String date, Image icon) {
      Map entry = new HashMap<>();
      entry.put("Line1", name);
      entry.put("Line2", date);

  ### Methods inherited from class Object

  `clone, equals, getClass, hashCode, notify, notifyAll, wait, wait, wait`

- ## Constructor Details

  - ### MultiList

    public MultiList(ListModel model)

    Constructor that accepts a model for the list

    ###### Parameters

    - `model`: the model object to assign to the list

  - ### MultiList

    public MultiList()
    Constructor for the GUI builder

- ## Method Details

  - ### initComponent

    protected void initComponent()
    Allows subclasses to bind functionality that relies on fully initialized and "ready for action" component state
    Overrides:
      `initComponent` in class `Component`

  - ### deinitialize

    protected void deinitialize()
    Description copied from class: `Component`
    Invoked to indicate that the component initialization is being reversed since the component was detached from the container hierarchy. This allows the component to deregister animators and cleanup after itself. This method is the opposite of the initComponent() method.
    Overrides:
      `deinitialize` in class `Component`

  - ### getSelectedButton

    public MultiButton getSelectedButton()

    Allows developers to customize the properties of the selected multi-button in code

    ###### Returns

    the selected multi button

  - ### getUnselectedButton

    public MultiButton getUnselectedButton()

    Allows developers to customize the properties of the unselected multi-button in code

    ###### Returns

    the unselected multi button

  - ### getPropertyNames

    public String[] getPropertyNames()

    A component may expose mutable property names for a UI designer to manipulate, this API is designed for usage internally by the GUI builder code

    ###### Returns

    the property names allowing mutation

    Overrides:
      `getPropertyNames` in class `Component`

  - ### getPropertyTypes

    public Class[] getPropertyTypes()

    Matches the property names method (see that method for further details).

    ###### Returns

    the types of the properties

    Overrides:
      `getPropertyTypes` in class `Component`

  - ### getPropertyValue

    public Object getPropertyValue(String name)

    Returns the current value of the property name, this method is used by the GUI builder

    ###### Parameters

    - `name`: the name of the property

    ###### Returns

    the value of said property

    Overrides:
      `getPropertyValue` in class `Component`

  - ### setPropertyValue

    public String setPropertyValue(String name, Object value)

    Sets a new value to the given property, returns an error message if failed and null if successful. Notice that some builtin properties such as "$designMode" might be sent to components to indicate application state.

    ###### Parameters

    - `name`: the name of the property

    - `value`: new value for the property

    ###### Returns

    error message or null

    Overrides:
