A widget that represents a simple <a> element.

If you want use this anchor only for changing history states, use `Hyperlink` instead.

### Built-in Bidi Text Support

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

### CSS Style Rules

- .gwt-Anchor { }

#### DEFAULT_DIRECTION_ESTIMATOR

    public static final DirectionEstimator DEFAULT_DIRECTION_ESTIMATOR

### Constructor Detail

#### Anchor

    public Anchor()

Creates an empty anchor.

The anchor's href is not set, which means that the widget will not not be styled with the browser's native link styles (such as underline and font color). Use `Anchor(boolean)` to add a default no-op href that does not open a link but ensures the native link styles are applied.

Sets the widget's 'access key'. This key is used (in conjunction with a browser-specific modifier key) to automatically focus the widget.

Specified by:
  `setAccessKey` in interface `Focusable`
Overrides:
  `setAccessKey` in class `FocusWidget`
Parameters:
  `key` - the widget's access key

#### setDirection

    @Deprecated
    public void setDirection(HasDirection.Direction direction)

Deprecated. Use `setDirectionEstimator(boolean)` and / or pass explicit direction to `setText(java.lang.String)`, `setHTML(com.google.gwt.safehtml.shared.SafeHtml)` instead
Description copied from interface: `HasDirection`
Sets the directionality for a widget.

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

#### setDirectionEstimator

    public void setDirectionEstimator(boolean enabled)

Toggles on / off direction estimation.

See note at `setDirectionEstimator(DirectionEstimator)`.

Specified by:
  `setDirectionEstimator` in interface `HasDirectionEstimator`
Parameters:
  `enabled` - Whether to enable direction estimation. If `true`, sets the `DirectionEstimator` object to a default `DirectionEstimator`.

#### setDirectionEstimator

    public void setDirectionEstimator(DirectionEstimator directionEstimator)

Sets the `DirectionEstimator` object.

Note: DirectionEstimator should be set before the widget has any content; it's highly recommended to set it using a constructor. Reason: if the widget already has non-empty content, this will update its direction according to the new estimator's result. This may cause flicker, and thus should be avoided.

Specified by:
  `setDirectionEstimator` in interface `HasDirectionEstimator`
Parameters:
  `directionEstimator` - The `DirectionEstimator` to be set. `null` means turning off direction estimation.

#### setFocus

    public void setFocus(boolean focused)

Description copied from interface: `Focusable`
Explicitly focus/unfocus this widget. Only one widget can have focus at a time, and the widget that does will receive all keyboard events. NOTE: Most browsers fire FocusEvents asynchronously. Especially within GWT tests, you'll need to make your test asynchronous to properly do verifications. See `GWTTestCase#delayTestFinish` for more information on how to do this.

Specified by:
  `setFocus` in interface `Focusable`
Overrides:
  `setFocus` in class `FocusWidget`
Parameters:
  `focused` - whether this widget should take focus or release it

#### setHorizontalAlignment

    public void setHorizontalAlignment(HasHorizontalAlignment.HorizontalAlignmentConstant align)

Description copied from interface: `HasHorizontalAlignment`
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.

Specified by:
  `setHorizontalAlignment` in interface `HasHorizontalAlignment`
Parameters:
  `align` - the horizontal alignment ( `HasHorizontalAlignment.ALIGN_LEFT`, `HasHorizontalAlignment.ALIGN_CENTER`, `HasHorizontalAlignment.ALIGN_RIGHT`, `HasHorizontalAlignment.ALIGN_JUSTIFY`, `HasHorizontalAlignment.ALIGN_LOCALE_START`, or `HasHorizontalAlignment.ALIGN_LOCALE_END`).

#### setHref

    public void setHref(SafeUri href)

Sets the anchor's href (the url to which it links).

Parameters:
  `href` - the anchor's href

#### setHref

    public void setHref(java.lang.String href)

Sets the anchor's href (the url to which it links).

Parameters:
  `href` - the anchor's href

#### setHTML

    public void setHTML(SafeHtml html)

Description copied from interface: `HasSafeHtml`
Sets this object's contents via known-safe HTML.

The object will behave exactly the same as when a widget's `HasHTML.setHTML(String)` method is invoked; however the `SafeHtml` passed to this method observes the contract that it can be used in an HTML context without causing unsafe script execution. Thus, unlike `HasHTML.setHTML(String)`, using this method cannot result in Cross-Site Scripting security vulnerabilities.

Specified by:
  `setHTML` in interface `HasSafeHtml`
Parameters:
  `html` - the object's new HTML, represented as a `SafeHtml` object

#### setHTML

    public void setHTML(java.lang.String html)

Description copied from interface: `HasHTML`
Sets this object's contents via HTML. Use care when setting an object's HTML; it is an easy way to expose script-based security problems. Consider using `HasText.setText(String)` whenever possible.

Specified by:
  `setHTML` in interface `HasHTML`
Parameters:
  `html` - the object's new HTML

#### setHTML

    public void setHTML(SafeHtml html,
                        HasDirection.Direction dir)

Description copied from interface: `HasDirectionalSafeHtml`
Sets this object's html, also declaring its direction.

Specified by:
  `setHTML` in interface `HasDirectionalSafeHtml`
Parameters:
  `html` - the object's new html
  `dir` - the html's direction

#### setName

    public void setName(java.lang.String name)

Description copied from interface: `HasName`
Sets the widget's name.

Specified by:
  `setName` in interface `HasName`
Parameters:
  `name` - the widget's new name

#### setTabIndex

    public void setTabIndex(int index)

Description copied from interface: `Focusable`
Sets the widget's position in the tab index. If more than one widget has the same tab index, each such widget will receive focus in an arbitrary order. Setting the tab index to `-1` will cause this widget to be removed from the tab order.

Specified by:
  `setTabIndex` in interface `Focusable`
Overrides:
  `setTabIndex` in class `FocusWidget`
