    public class RichTextArea

extends FocusWidget
implements HasHTML, HasInitializeHandlers

A rich text editor that allows complex styling and formatting. Because some browsers do not support rich text editing, and others support only a limited subset of functionality, there are two formatter interfaces, accessed via `getBasicFormatter()` and `getExtendedFormatter()` . A browser that does not support rich text editing at all will return `null` for both of these, while one that supports only the basic functionality will return `null` for the latter.

### CSS Style Rules

.gwt-RichTextArea
  Applied to the rich text element.

Constructor Detail

### RichTextArea

    public RichTextArea()

  Creates a new, blank `RichTextArea` object with no stylesheet.

Method Detail

### addInitializeHandler

    public HandlerRegistration addInitializeHandler(InitializeHandler handler)

  Description copied from interface: `HasInitializeHandlers`
  Adds a `InitializeEvent` handler.

  Specified by:
    `addInitializeHandler` in interface `HasInitializeHandlers`
  Parameters:
    `handler` - the handler
  Returns:
    the registration for the event

### getBasicFormatter

    @Deprecated
    public RichTextArea.BasicFormatter getBasicFormatter()

  Deprecated. use `getFormatter()` instead

  Gets the basic rich text formatting interface. Note that formatting can only be done when the `RichTextArea` is attached, visible on the page, and has been focused by the user.

  Returns:
    `null` if basic formatting is not supported

### getExtendedFormatter

    @Deprecated
    public RichTextArea.ExtendedFormatter getExtendedFormatter()

  Deprecated. use `getFormatter()` instead

  Gets the full rich text formatting interface. Note that formatting can only be done when the `RichTextArea` is attached, visible on the page, and has been focused by the user.

  Returns:
    `null` if full formatting is not supported

### getFormatter

    public RichTextArea.Formatter getFormatter()

  Gets the rich text formatting interface. Note that formatting can only be done when the `RichTextArea` is attached, visible on the page, and has been focused by the user.

  Returns:
    `null` if full formatting is not supported

### getHTML

    public java.lang.String getHTML()

  Description copied from interface: `HasHTML`
  Gets this object's contents as HTML.

  Specified by:
    `getHTML` in interface `HasHTML`
  Returns:
    the object's HTML

### getText

    public java.lang.String getText()

  Description copied from interface: `HasText`
  Gets this object's text.

  Specified by:
    `getText` in interface `HasText`
  Returns:
    the object's text

### 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.

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

### 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

### setText

    public void setText(java.lang.String text)

  Description copied from interface: `HasText`
  Sets this object's text.

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

### onAttach

    protected void onAttach()

  Description copied from class: `Widget`

  This method is called when a widget is attached to the browser's document. To receive notification after a Widget has been added to the document, override the `Widget.onLoad()` method.

  It is strongly recommended that you override `Widget.onLoad()` or `Widget.doAttachChildren()` instead of this method to avoid inconsistencies between logical and physical attachment states.

  Subclasses that override this method must call `super.onAttach()` to ensure that the Widget has been attached to its underlying Element.

  Overrides:
    `onAttach` in class `Widget`
  See Also:
    `Widget.onLoad()`, `Widget.doAttachChildren()`

### onDetach

    protected void onDetach()

  Description copied from class: `Widget`

  This method is called when a widget is detached from the browser's document. To receive notification before a Widget is removed from the document, override the `Widget.onUnload()` method.

  It is strongly recommended that you override `Widget.onUnload()` or `Widget.doDetachChildren()` instead of this method to avoid inconsistencies between logical and physical attachment states.

  Subclasses that override this method must call `super.onDetach()` to ensure that the Widget has been detached from the underlying Element. Failure to do so will result in application memory leaks due to circular references between DOM Elements and JavaScript objects.

  Overrides:
    `onDetach` in class `Widget`
  See Also:
    `Widget.onUnload()`, `Widget.doDetachChildren()`
