public class LinkItem extends StaticTextItem
A form item that displays a URL. In the default read-only mode (`canEdit` is `false`) the URL is shown as a link; in editable mode the URL is shown in a textbox.

The link to open is specified as the item value with `FormItem.setValue()` or `FormItem.defaultValue`. The link title defaults to the URL unless `linkTitle` is specified.

Additionally, a custom action can be triggered when the link is clicked: see `target` for details.

      Current iconVAlign value. Default value is "center"

  - ### setLinkTitle

    public LinkItem setLinkTitle(String linkTitle)
    Optional title HTML to display for this item's link. If unset, the `LinkItem`'s value (the URL) will be used for the link's title.
    If this method is called after the component has been drawn/initialized: Setter for `linkTitle`.
    Parameters:
      `linkTitle` - new `linkTitle` HTML. Default value is null
    Returns:
      `LinkItem` instance, for chaining setter calls
    See Also:
      - `HTMLString`

  - ### getLinkTitle

    public String getLinkTitle()
    Optional title HTML to display for this item's link. If unset, the `LinkItem`'s value (the URL) will be used for the link's title.
    Returns:
      Current linkTitle value. Default value is null
    See Also:
      - `HTMLString`

  - ### setReadOnlyDisplay

    public LinkItem setReadOnlyDisplay(ReadOnlyDisplayAppearance readOnlyDisplay)
    If `canEdit` is set to `false`, how should this `LinkItem` be displayed to the user?

    Link items are, by default, canEdit:false. Note that the link remains active regardless of the `readOnlyDisplay` setting.

    Overrides:
      `setReadOnlyDisplay` in class `FormItem`
    Parameters:
      `readOnlyDisplay` - New readOnlyDisplay value. Default value is null
    Returns:
      `LinkItem` instance, for chaining setter calls
    See Also:
      - `DynamicForm.setReadOnlyDisplay(com.smartgwt.client.types.ReadOnlyDisplayAppearance)`
      - `Appearance overview and related methods`

  - ### getReadOnlyDisplay

    public ReadOnlyDisplayAppearance getReadOnlyDisplay()
    If `canEdit` is set to `false`, how should this `LinkItem` be displayed to the user?

    Link items are, by default, canEdit:false. Note that the link remains active regardless of the `readOnlyDisplay` setting.

    Overrides:
      `getReadOnlyDisplay` in class `FormItem`
    Returns:
      Current readOnlyDisplay value. Default value is null
    See Also:
      - `DynamicForm.getReadOnlyDisplay()`
      - `Appearance overview and related methods`

  - ### setTarget

    public LinkItem setTarget(String target)
    By default, clicking a link rendered by this item opens it in a new browser window. You can alter this behavior by setting this property. The value of this property will be passed as the value to the `target` attribute of the anchor tag used to render the link.

    If you set linkItem.target to "javascript", the default behaviour is to catch and consume mouse-clicks that would result in the link being followed. Instead, the `FormItem.click()` event is fired.

    Parameters:
      `target` - New target value. Default value is "_blank"
    Returns:
      `LinkItem` instance, for chaining setter calls

  - ### getTarget

    public String getTarget()
    By default, clicking a link rendered by this item opens it in a new browser window. You can alter this behavior by setting this property. The value of this property will be passed as the value to the `target` attribute of the anchor tag used to render the link.

    If you set linkItem.target to "javascript", the default behaviour is to catch and consume mouse-clicks that would result in the link being followed. Instead, the `FormItem.click()` event is fired.

    Returns:
      Current target value. Default value is "_blank"

  - ### setDefaultProperties

    public static void setDefaultProperties(LinkItem linkItemProperties)
    Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties of the class instance passed to this function. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

    Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

    Parameters:
      `linkItemProperties` - properties that should be used as new defaults when instances of this class are created
    See Also:
      - `SGWTProperties`

  - ### addClickHandler

    public HandlerRegistration addClickHandler(ClickHandler handler)
    Description copied from class: `FormItem`
    Add a click handler.

    Called when this FormItem is clicked on.

    Note: `click()` is available on StaticTextItem, BlurbItems, ButtonItem, and derivatives. Other form items (such as HiddenItem) do not support `click()`.

    Specified by:
      `addClickHandler` in interface `HasClickHandlers`
    Overrides:
      `addClickHandler` in class `FormItem`
    Parameters:
      `handler` - the click handler
    Returns:
      `HandlerRegistration` used to remove this handler
