Constructor Detail

### EditTextCell

    public EditTextCell()

  Construct a new EditTextCell that will use a `SimpleSafeHtmlRenderer`.

### EditTextCell

    public EditTextCell(SafeHtmlRenderer<java.lang.String> renderer)

  Construct a new EditTextCell that will use a given `SafeHtmlRenderer` to render the value when not in edit mode.

  Parameters:
    `renderer` - a `SafeHtmlRenderer` instance

Method Detail

### isEditing

    public boolean isEditing(Cell.Context context,
                             Element parent,
                             java.lang.String value)

  Description copied from class: `AbstractEditableCell`
  Returns true if the cell is currently editing the data identified by the given element and key. While a cell is editing, widgets containing the cell may choose to pass keystrokes directly to the cell rather than using them for navigation purposes.

  Specified by:
    `isEditing` in interface `Cell<java.lang.String>`
  Specified by:
    `isEditing` in class `AbstractEditableCell<java.lang.String,EditTextCell.ViewData>`
  Parameters:
    `context` - the `Context` of the cell
    `parent` - the parent Element
    `value` - the value associated with the cell
  Returns:
    true if the cell is in edit mode

### onBrowserEvent

    public void onBrowserEvent(Cell.Context context,
                               Element parent,
                               java.lang.String value,
                               NativeEvent event,
                               ValueUpdater<java.lang.String> valueUpdater)

  Description copied from class: `AbstractCell`
  Handle a browser event that took place within the cell. The default implementation returns null.

  If you override this method to add support for events, remember to pass the event types that the cell expects into the constructor.

  Specified by:
    `onBrowserEvent` in interface `Cell<java.lang.String>`
  Overrides:
    `onBrowserEvent` in class `AbstractCell<java.lang.String>`
  Parameters:
    `context` - the `Cell.Context` of the cell
    `parent` - the parent Element
    `value` - the value associated with the cell
    `event` - the native browser event
    `valueUpdater` - a `ValueUpdater`, or null if not specified

### render

    public void render(Cell.Context context,
                       java.lang.String value,
                       SafeHtmlBuilder sb)

  Description copied from interface: `Cell`
  Render a cell as HTML into a `SafeHtmlBuilder`, suitable for passing to `Element.setInnerHTML(String)` on a container element.

  Note: If your cell contains natively focusable elements, such as buttons or input elements, be sure to set the tabIndex to -1 so that they do not steal focus away from the containing widget.

  Specified by:
    `render` in interface `Cell<java.lang.String>`
  Specified by:
    `render` in class `AbstractCell<java.lang.String>`
  Parameters:
    `context` - the `Cell.Context` of the cell
    `value` - the cell value to be rendered
    `sb` - the `SafeHtmlBuilder` to be written to

### resetFocus

    public boolean resetFocus(Cell.Context context,
                              Element parent,
                              java.lang.String value)

  Description copied from class: `AbstractCell`
  Reset focus on the Cell. This method is called if the cell has focus when it is refreshed.

  This method is a no-op and returns false. If your cell is editable or can be focused by the user, override this method to reset focus when the containing widget is refreshed.

  Specified by:
    `resetFocus` in interface `Cell<java.lang.String>`
  Overrides:
    `resetFocus` in class `AbstractCell<java.lang.String>`
  Parameters:
    `context` - the `Cell.Context` of the cell
    `parent` - the parent Element
    `value` - the value associated with the cell
  Returns:
    true if focus is taken, false if not

### edit

    protected void edit(Cell.Context context,
                        Element parent,
                        java.lang.String value)

  Convert the cell to edit mode.

  Parameters:
    `context` - the `Context` of the cell
    `parent` - the parent element
    `value` - the current value
