    Fields
    Modifier and Type | Field | Description
    --- | --- | ---
    `static HasHorizontalAlignment.AutoHorizontalAlignmentConstant` | `ALIGN_CONTENT_END` | Specifies that the widget's contents should be aligned right for LTR content, left for RTL content, and if the content's direction is DEFAULT, like `HasHorizontalAlignment.ALIGN_LOCALE_END`.
    `static HasHorizontalAlignment.AutoHorizontalAlignmentConstant` | `ALIGN_CONTENT_START` | Specifies that the widget's contents should be aligned left for LTR content, right for RTL content, and if the content's direction is DEFAULT, like `HasHorizontalAlignment.ALIGN_LOCALE_START`.

    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method | Description
    --- | --- | ---
    `HasHorizontalAlignment.AutoHorizontalAlignmentConstant` | `getAutoHorizontalAlignment()` | Gets the horizontal auto-alignment setting.
    `void` | `setAutoHorizontalAlignment​(HasHorizontalAlignment.AutoHorizontalAlignmentConstant autoHorizontalAlignment)` | Sets the horizontal alignment, allowing in addition to the "static" `HasHorizontalAlignment.HorizontalAlignmentConstant` values, the "automatic" `HasHorizontalAlignment.AutoHorizontalAlignmentConstant` values that depend on the content direction.

- - ### Field Detail

    - #### ALIGN_CONTENT_START

          static final HasHorizontalAlignment.AutoHorizontalAlignmentConstant ALIGN_CONTENT_START

      Specifies that the widget's contents should be aligned left for LTR content, right for RTL content, and if the content's direction is DEFAULT, like `HasHorizontalAlignment.ALIGN_LOCALE_START`.

    - #### ALIGN_CONTENT_END

          static final HasHorizontalAlignment.AutoHorizontalAlignmentConstant ALIGN_CONTENT_END

      Specifies that the widget's contents should be aligned right for LTR content, left for RTL content, and if the content's direction is DEFAULT, like `HasHorizontalAlignment.ALIGN_LOCALE_END`.

  - ### Method Detail

    - #### getAutoHorizontalAlignment

          HasHorizontalAlignment.AutoHorizontalAlignmentConstant getAutoHorizontalAlignment()

      Gets the horizontal auto-alignment setting. This may be one of the auto-alignment values above that depend on content direction (e.g. `ALIGN_CONTENT_START`), or one of the "static" `HasHorizontalAlignment.HorizontalAlignmentConstant` alignment values (e.g. `HasHorizontalAlignment.ALIGN_LOCALE_START`). It may be set by either `setAutoHorizontalAlignment` or `HasHorizontalAlignment#setHorizontalAlignment`. The default is null, indicating that no specific horizontal alignment has been set, allowing it to be determined by the usual HTML and CSS mechanisms.
      Returns:
        the current automatic horizontal alignment policy.

    - #### setAutoHorizontalAlignment

          void setAutoHorizontalAlignment​(HasHorizontalAlignment.AutoHorizontalAlignmentConstant autoHorizontalAlignment)

      Sets the horizontal alignment, allowing in addition to the "static" `HasHorizontalAlignment.HorizontalAlignmentConstant` values, the "automatic" `HasHorizontalAlignment.AutoHorizontalAlignmentConstant` values that depend on the content direction. Determines the values returned by both `getAutoHorizontalAlignment()` and `HasHorizontalAlignment.getHorizontalAlignment()`.

      For the `ALIGN_CONTENT_START` and `ALIGN_CONTENT_END` values, sets the horizontal alignment (including the value of `HasHorizontalAlignment#getHorizontalAlignment()`) to the start or end edge of the current content's direction, respectively, and continues to automatically update it whenever the content direction changes.

      For other values, operates like `HasHorizontalAlignment.setHorizontalAlignment(com.google.gwt.user.client.ui.HasHorizontalAlignment.HorizontalAlignmentConstant)`.

      For `null`, the horizontal alignment is cleared, allowing it to be determined by the standard HTML mechanisms such as inheritance and CSS rules.

      Parameters:
        `autoHorizontalAlignment` - the new automatic horizontal alignment policy
