Constructor Detail

### HTMLPanel

    public HTMLPanel(java.lang.String html)

  Creates an HTML panel with the specified HTML contents. Any element within this HTML that has a specified id can contain a child widget.

  Parameters:
    `html` - the panel's HTML

Method Detail

### createUniqueId

    public static java.lang.String createUniqueId()

  A helper method for creating unique IDs for elements within dynamically- generated HTML. This is important because no two elements in a document should have the same id.

  Returns:
    a new unique identifier

### add

    public void add(Widget widget,
                    java.lang.String id)

  Adds a child widget to the panel, contained within the HTML element specified by a given id.

  Parameters:
    `widget` - the widget to be added
    `id` - the id of the element within which it will be contained

### addAndReplaceElement

    public void addAndReplaceElement(Widget widget,
                                     java.lang.String id)

  Adds a child widget to the panel, replacing the HTML element specified by a given id.

  Parameters:
    `widget` - the widget to be added
    `id` - the id of the element to be replaced by the widget

### getElementById

    public Element getElementById(java.lang.String id)

  Finds an `element` within this panel by its id. This method uses `Document.getElementById(String)`, so the id must still be unique within the document.

  Parameters:
    `id` - the id of the element to be found
  Returns:
    the element with the given id, or `null` if none is found
