    Construct a new CheckboxCell.
  - CheckboxCell
```
@Deprecated
public CheckboxCell(boolean isSelectBox)
```
    Deprecated. use CheckboxCell(boolean, boolean) instead
    
    Construct a new CheckboxCell that optionally controls selection.
    
    Parameters:
    isSelectBox - true if the cell controls the selection state
  - CheckboxCell
```
public CheckboxCell(boolean dependsOnSelection,
            boolean handlesSelection)
```
    Construct a new CheckboxCell that optionally controls selection.
    
    Parameters:
    dependsOnSelection - true if the cell depends on the selection state
    handlesSelection - true if the cell modifies the selection state
- Method Detail
  - dependsOnSelection
```
public boolean dependsOnSelection()
```
    Description copied from interface: Cell
    
    Check if this cell depends on the selection state.
    
    Specified by:
    
    dependsOnSelection in interface Cell<java.lang.Boolean>
    
    Overrides:
    
    dependsOnSelection in class AbstractCell<java.lang.Boolean>
    
    Returns:
    true if dependent on selection, false if not
  - handlesSelection
```
public boolean handlesSelection()
```
    Description copied from interface: Cell
    
    Check if this cell handles selection. If the cell handles selection, then its container should not automatically handle selection.
    
    Specified by:
    
    handlesSelection in interface Cell<java.lang.Boolean>
    
    Overrides:
    
    handlesSelection in class AbstractCell<java.lang.Boolean>
    
    Returns:
    true if the cell handles selection, false if not
  - isEditing
```
public boolean isEditing(Cell.Context context,
                Element parent,
                java.lang.Boolean 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.Boolean>
    
    Specified by:
    
    isEditing in class AbstractEditableCell<java.lang.Boolean,java.lang.Boolean>
    
    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.Boolean value,
                  NativeEvent event,
                  ValueUpdater<java.lang.Boolean> 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.Boolean>
    
    Overrides:
    
    onBrowserEvent in class AbstractCell<java.lang.Boolean>
    
    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.Boolean 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.Boolean>
    
    Specified by:
    
    render in class AbstractCell<java.lang.Boolean>
    
    Parameters:
    context - the Cell.Context of the cell
    value - the cell value to be rendered
    sb - the SafeHtmlBuilder to be written to
