Characteristic interface which indicates that a widget can be aligned horizontally.

Use in UiBinder Templates

The names of the static members of {@link HorizontalAlignmentConstant}, as well as simple alignment names (left, center, right, justify), can be used as values for a horizontalAlignment attribute of any widget that implements this interface. (In fact, this will work for any widget method that takes a single HorizontalAlignmentConstant value.)

For example,

<g:Label horizontalAlignment='ALIGN_RIGHT'>Hi there.</g:Label>
<g:Label horizontalAlignment='right'>Hi there.</g:Label>

 /**
  * Specifies that the widget's contents should be aligned in the center.
  */

 /**
  * Specifies that the widget's contents should be aligned as justify.
  */
 static const HorizontalAlignmentConstant ALIGN_JUSTIFY = const HorizontalAlignmentConstant(TextAlign.JUSTIFY);

 /**
  * Specifies that the widget's contents should be aligned to the left.
  */
