Interface HasHorizontalAlignment

All Known Subinterfaces:
  HasAlignment, HasAutoHorizontalAlignment

All Known Implementing Classes:
  Anchor, Column, DateLabel, DialogBox.CaptionImpl, DockPanel, HorizontalPanel, HTML, IdentityColumn, InlineHTML, InlineLabel, Label, LabelBase, NumberLabel, TextColumn, ValueLabel, VerticalPanel

    public interface HasHorizontalAlignment

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

### Use in UiBinder Templates

The names of the static members of `HasHorizontalAlignment.AutoHorizontalAlignmentConstant`, 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>

Nested Class Summary
`static class` | `HasHorizontalAlignment.AutoHorizontalAlignmentConstant` Type for values defined and used in `HasAutoHorizontalAlignment`.
`static class` | `HasHorizontalAlignment.HorizontalAlignmentConstant` Possible return values for `getHorizontalAlignment()`, and parameter values for `setHorizontalAlignment(com.google.gwt.user.client.ui.HasHorizontalAlignment.HorizontalAlignmentConstant)`.

Field Summary
`static HasHorizontalAlignment.HorizontalAlignmentConstant` | `ALIGN_CENTER` Specifies that the widget's contents should be aligned in the center.
`static HasHorizontalAlignment.HorizontalAlignmentConstant` | `ALIGN_DEFAULT` Synonym of `ALIGN_LOCALE_START`.
`static HasHorizontalAlignment.HorizontalAlignmentConstant` | `ALIGN_JUSTIFY` Specifies that the widget's contents should be aligned as justify.
`static HasHorizontalAlignment.HorizontalAlignmentConstant` | `ALIGN_LEFT` Specifies that the widget's contents should be aligned to the left.
`static HasHorizontalAlignment.HorizontalAlignmentConstant` | `ALIGN_LOCALE_END` In a RTL layout, specifies that the widget's contents should be aligned to the left.
`static HasHorizontalAlignment.HorizontalAlignmentConstant` | `ALIGN_LOCALE_START` In a RTL layout, specifies that the widget's contents should be aligned to the right.
`static HasHorizontalAlignment.HorizontalAlignmentConstant` | `ALIGN_RIGHT` Specifies that the widget's contents should be aligned to the right.

Method Summary
`HasHorizontalAlignment.HorizontalAlignmentConstant` | `getHorizontalAlignment()` Gets the horizontal alignment.
`void` | `setHorizontalAlignment(HasHorizontalAlignment.HorizontalAlignmentConstant align)` Sets the horizontal alignment.

Field Detail

### ALIGN_CENTER

    static final HasHorizontalAlignment.HorizontalAlignmentConstant ALIGN_CENTER

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

### ALIGN_JUSTIFY

    static final HasHorizontalAlignment.HorizontalAlignmentConstant ALIGN_JUSTIFY

  Specifies that the widget's contents should be aligned as justify.

### ALIGN_LEFT

    static final HasHorizontalAlignment.HorizontalAlignmentConstant ALIGN_LEFT

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

### ALIGN_RIGHT

    static final HasHorizontalAlignment.HorizontalAlignmentConstant ALIGN_RIGHT

  Specifies that the widget's contents should be aligned to the right.

### ALIGN_LOCALE_START

    static final HasHorizontalAlignment.HorizontalAlignmentConstant ALIGN_LOCALE_START

  In a RTL layout, specifies that the widget's contents should be aligned to the right. In a LTR layout, specifies that the widget's constants should be aligned to the left.

### ALIGN_LOCALE_END

    static final HasHorizontalAlignment.HorizontalAlignmentConstant ALIGN_LOCALE_END

  In a RTL layout, specifies that the widget's contents should be aligned to the left. In a LTR layout, specifies that the widget's constants should be aligned to the right.

### ALIGN_DEFAULT

    static final HasHorizontalAlignment.HorizontalAlignmentConstant ALIGN_DEFAULT

  Synonym of `ALIGN_LOCALE_START`.

Method Detail

### getHorizontalAlignment

    HasHorizontalAlignment.HorizontalAlignmentConstant getHorizontalAlignment()

  Gets the horizontal alignment.

  Returns:
    the current horizontal alignment ( `ALIGN_LEFT`, `ALIGN_CENTER`, `ALIGN_RIGHT`, `ALIGN_JUSTIFY`, or null).

### setHorizontalAlignment

    void setHorizontalAlignment(HasHorizontalAlignment.HorizontalAlignmentConstant align)

  Sets the horizontal alignment.

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

  Parameters:
    `align` - the horizontal alignment ( `ALIGN_LEFT`, `ALIGN_CENTER`, `ALIGN_RIGHT`, `ALIGN_JUSTIFY`, `ALIGN_LOCALE_START`, or `ALIGN_LOCALE_END`).
