Public Constructors

public CheckboxCell ()

Construct a new CheckboxCell.

public CheckboxCell (boolean isSelectBox)

This constructor is deprecated.
use CheckboxCell(boolean, boolean) instead

Construct a new CheckboxCell that optionally controls selection.

Parameters
isSelectBox true if the cell controls the selection state

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

Public Methods

public boolean dependsOnSelection ()

Check if this cell depends on the selection state.

Returns
  • true if dependent on selection, false if not

public boolean handlesSelection ()

Check if this cell handles selection. If the cell handles selection, then its container should not automatically handle selection.

Returns
  • true if the cell handles selection, false if not

public boolean isEditing (Cell.Context context, Element parent, Boolean value)

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.

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

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

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.

Parameters
context the 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

public void render (Cell.Context context, Boolean value, SafeHtmlBuilder sb)

Render a cell as HTML into a SafeHtmlBuilder, suitable for passing to 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.

Parameters
context the Context of the cell
value the cell value to be rendered
sb the SafeHtmlBuilder to be written to
