• getOptions

  public List<V> getOptions()

  Description copied from interface: UiAbstractChoice
  This method gets the options of this object. The options are the available values to choose a selection from. The List shall not contain duplicate entries. It may contain the value null. In such case set a custom formatter that provides a reasonable display value for the null option.
  ATTENTION: Do not update the List of options from outside. See UiAbstractChoice.setOptions(List) for details.

  Specified by:

  getOptions in interface UiAbstractChoice<V,​V>

  Returns:

  the List with all available options.

• setOptions

  public void setOptions​(List<V> options)

  Description copied from interface: UiAbstractChoice
  This method sets the options of this object. The options will be presented in their order specified by the given List.
  ATTENTION: The options are updated during this method. Changing the List instance after calling this method will not reflect the changes unless this method is called again.

  Specified by:

  setOptions in interface UiAbstractChoice<V,​V>

  Parameters:

  options - the new List of available options.

• getFormatter

  public Function<V,​String> getFormatter()

  Specified by:

  getFormatter in interface UiAbstractChoice<V,​V>

  Returns:

  the formatter to format an option to String in order to display it in the UI. By default it will simply use ToStringFormatter. Use UiAbstractChoice.setFormatter(Function) to change default.

• setFormatter

  public void setFormatter​(Function<V,​String> formatter)

  Specified by:

  setFormatter in interface UiAbstractChoice<V,​V>

  Parameters:

  formatter - the new value of UiAbstractChoice.getFormatter().

• setText

  public void setText​(String text)

  Specified by:

  setText in interface AttributeWriteText

  Parameters:

  text - is the new text to set.

• getValueOrThrow

  public V getValueOrThrow()

  Specified by:

  getValueOrThrow in interface UiValidatableWidget<V>

  Returns:

  the current value.

• getText

  public String getText()

  Specified by:

  getText in interface AttributeWriteText

  Returns:

  the label or text of this widget. Will be the empty string if no text has been set. If used as label the text is permanently displayed as information for the user to describe its meaning (lettering for button or label). Otherwise for textual inputs the text is the plain value as text entered by the end-user. If the value type is not String (e.g. for UiComboBox) this gives direct access to the plain text entered by the end-user (even in case it is not a valid option). This can be useful in a combo-box in case value is undefined to accept the text as a new option (e.g. for a tag).

• setValueNative

  protected void setValueNative​(V value)

  Specified by:

  setValueNative in class TvmInput<V,​org.teavm.jso.dom.html.HTMLSelectElement>

  Parameters:

  value - the new value to set in the native widget.
