All Implemented Interfaces:
IContentData<MLItemProp>, IMLActionButtonListener, IMLArrowActionListener
public class MLSpinner extends MLItem implements IMLArrowActionListener, IMLActionButtonListener
Spinner is a value field that will show a drop-down widget to select its value from.

The spinner value can be preceded with a leading text with an optional fixed width, and the text entry will take up the remaining space in the list item.

The spinner may have a fixed width and be trailing justified (i.e. right for LTR or left for RTL).

An action button can be added to the trailing side.

An optional description text can be added to the bottom of the list item.

    • onArrowInvoked

      public void onArrowInvoked(MLItem item)

      onArrowInvoked in interface IMLArrowActionListener
      Parameters:
      item - "this" item.
