Constructor Detail

### CellBrowser.BrowserCellList

    public CellBrowser.BrowserCellList(Cell<T> cell,
                                       int level,
                                       ProvidesKey<T> keyProvider)

Method Detail

### deselectValue

    protected void deselectValue()

### getCellParent

    protected Element getCellParent(Element item)

  Description copied from class: `CellList`
  Get the parent element that wraps the cell from the list item. Override this method if you add structure to the element.

  Overrides:
    `getCellParent` in class `CellList<T>`
  Parameters:
    `item` - the row element that wraps the list item
  Returns:
    the parent element of the cell

### isKeyboardNavigationSuppressed

    protected boolean isKeyboardNavigationSuppressed()

  Description copied from class: `AbstractHasData`
  Check if keyboard navigation is being suppressed, such as when the user is editing a cell.

  Overrides:
    `isKeyboardNavigationSuppressed` in class `CellList<T>`
  Returns:
    true if suppressed, false if not

### onBrowserEvent2

    protected void onBrowserEvent2(Event event)

  Description copied from class: `AbstractHasData`
  Called after `AbstractHasData.onBrowserEvent(Event)` completes.

  Overrides:
    `onBrowserEvent2` in class `CellList<T>`
  Parameters:
    `event` - the event that was fired

### renderRowValues

    protected void renderRowValues(SafeHtmlBuilder sb,
                                   java.util.List<T> values,
                                   int start,
                                   SelectionModel<? super T> selectionModel)

  Description copied from class: `AbstractHasData`
  Render all row values into the specified `SafeHtmlBuilder`.

  Subclasses can optionally throw an `UnsupportedOperationException` if they prefer to render the rows in `AbstractHasData.replaceAllChildren(List, SafeHtml)` and `AbstractHasData.replaceChildren(List, int, SafeHtml)`. In this case, the `SafeHtml` argument will be null. Though a bit hacky, this is designed to supported legacy widgets that use `SafeHtmlBuilder`, and newer widgets that use other builders, such as the ElementBuilder API.

  Overrides:
    `renderRowValues` in class `CellList<T>`
  Parameters:
    `sb` - the `SafeHtmlBuilder` to render into
    `values` - the row values
    `start` - the absolute start index of the values
    `selectionModel` - the `SelectionModel`

### setKeyboardSelected

    protected void setKeyboardSelected(int index,
                                       boolean selected,
                                       boolean stealFocus)

  Description copied from class: `AbstractHasData`
  Update an element to reflect its keyboard selected state.

  Overrides:
    `setKeyboardSelected` in class `CellList<T>`
  Parameters:
    `index` - the index of the element
    `selected` - true if selected, false if not
    `stealFocus` - true if the row should steal focus, false if not

### setSelectedValue

    protected void setSelectedValue(T value)

  Set the selected value in this list. If there is already a selected value, the old value will be deselected.

  Parameters:
    `value` - the selected value
