      public class Label
      extends LabelBase<java.lang.String>
      implements HasDirectionalText, HasDirection, HasClickHandlers, HasDoubleClickHandlers, SourcesClickEvents, SourcesMouseEvents, HasAllDragAndDropHandlers, HasAllGestureHandlers, HasAllMouseHandlers, HasAllTouchHandlers, IsEditor<LeafValueEditor<java.lang.String>>

  A widget that contains arbitrary text, not interpreted as HTML. This widget uses a <div> element, causing it to be displayed with block layout.

  ### Built-in Bidi Text Support

  This widget is capable of automatically adjusting its direction according to its content. This feature is controlled by `LabelBase.setDirectionEstimator(boolean)` or passing a DirectionEstimator parameter to the constructor, and is off by default.

  ### CSS Style Rules

  - .gwt-Label { }

  ### Example

  >     public class HTMLExample implements EntryPoint {

  >       public void onModuleLoad() {
  >         // Create a Label and an HTML widget.
  >         Label lbl = new Label("This is just text.  It will not be interpreted "
  >           + "as <html>.");

  >         HTML html = new HTML(
  >           "This is <b>HTML</b>.  It will be interpreted as such if you specify "
  >             + "the <span style='font-family:fixed'>asHTML</span> flag.", true);

  >         // Add them to the root panel.
  >         VerticalPanel panel = new VerticalPanel();
  >         panel.add(lbl);
  >         panel.add(html);

    - #### setDirection

          @Deprecated
          public void setDirection​(HasDirection.Direction direction)

      Deprecated.
      Use `LabelBase.setDirectionEstimator(boolean)` and / or pass explicit direction to `setText(java.lang.String)` instead
      Sets the widget element's direction.
      Specified by:
        `setDirection` in interface `HasDirection`
      Parameters:
        `direction` - `RTL` if the directionality should be set to right-to-left, `LTR` if the directionality should be set to left-to-right `DEFAULT` if the directionality should not be explicitly set

    - #### setText

          public void setText​(java.lang.String text)

      Sets the label's content to the given text.

      Doesn't change the widget's direction or horizontal alignment if `directionEstimator` is null. Otherwise, the widget's direction is set using the estimator, and its alignment may therefore change as described in `setText(String, Direction)`.

      Specified by:
        `setText` in interface `HasText`
      Parameters:
        `text` - the widget's new text

    - #### setText

          public void setText​(java.lang.String text,
                              HasDirection.Direction dir)

      Sets the label's content to the given text, applying the given direction.

      This will have the following effect on the horizontal alignment:

      - If the automatic alignment setting is ALIGN_CONTENT_START or ALIGN_CONTENT_END, the horizontal alignment will be set to match the start or end edge, respectively, of the new direction (the `dir` parameter). If that is DEFAULT, the locale direction is used.
      - Otherwise, the horizontal alignment value is not changed, but the effective alignment may nevertheless change according to the usual HTML rules, i.e. it will match the start edge of the new direction if the widget element is a <div> and has no explicit alignment value even by inheritance.
      Specified by:
        `setText` in interface `HasDirectionalText`
      Parameters:
        `text` - the widget's new text
        `dir` - the text's direction. Note: `Direction.DEFAULT` means direction should be inherited from the widget's parent element.
