  - - javafx.scene.control.Labeled
    - - javafx.scene.control.Cell<T>
      - javafx.scene.control.IndexedCell<T>
        
        javafx.scene.control.TreeTableCell<S,T>

Type Parameters:

S - The type of the TreeTableView generic type

T - The type of the item contained within the Cell.

All Implemented Interfaces:

Skinnable
```
public class TreeTableCell<S,T>
extends IndexedCell<T>
```
Represents a single row/column intersection in a TreeTableView. To represent this intersection, a TreeTableCell contains an index property, as well as a tableColumn property. In addition, a TreeTableCell instance knows what TreeTableRow it exists in.
A note about selection: A TreeTableCell visually shows it is selected when two conditions are met:
1. The TableSelectionModel.isSelected(int, TableColumnBase) method returns true for the row / column that this cell represents, and
2. The cell selection mode property is set to true (to represent that it is allowable to select individual cells (and not just rows of cells)).
Since:

JavaFX 8.0

  - startEdit

public void startEdit()
```
    Call this function to transition from a non-editing state into an editing state, if the cell is editable. If this cell is already in an editing state, it will stay in it.
    
    Overrides:
    
    startEdit in class Cell<T>
  - commitEdit
```
public void commitEdit(T newValue)
```
    Call this function when appropriate (based on the user interaction requirements of your cell editing user interface) to do two things:
    1. Fire the appropriate events back to the backing UI control (e.g. ListView). This will begin the process of pushing this edit back to the relevant data source / property (although it does not guarantee that this will be successful - that is dependent upon the specific edit commit handler being used). Refer to the UI control class javadoc for more detail.
    2. Begin the transition from an editing state into a non-editing state.
    In general there is no need to override this method in custom cell implementations - it should be sufficient to simply call this method when appropriate (e.g. when the user pressed the Enter key, you may do something like cell.commitEdit(converter.fromString(textField.getText()));
    Overrides:
    
    commitEdit in class Cell<T>
    
    Parameters:
    
    newValue - The value as input by the end user, which should be persisted in the relevant way given the data source underpinning the user interface and the install edit commit handler of the UI control.
  - cancelEdit
```
public void cancelEdit()
```
    Call this function to transition from an editing state into a non-editing state, without saving any user input.
    
    Overrides:
    
    cancelEdit in class Cell<T>
  - updateSelected
```
public void updateSelected(boolean selected)
```
    Updates whether this cell is in a selected state or not.
    
    Overrides:
    
    updateSelected in class Cell<T>
    
    Parameters:
    
    selected - whether or not to select this cell.
  - indexChanged
```
void indexChanged(int oldIndex,
                  int newIndex)
```
    This method is called whenever the index is changed, regardless of whether the new index is the same as the old index.
    
    Overrides:
    
    indexChanged in class IndexedCell<T>

  - updateTreeTableView
```
public final void updateTreeTableView(TreeTableView<S> tv)
```
    Updates the TreeTableView associated with this TreeTableCell. This is typically only done once when the TreeTableCell is first added to the TreeTableView. Note: This function is intended to be used by experts, primarily by those implementing new Skins. It is not common for developers or designers to access this function directly.
    
    Parameters:
    
    tv - the TreeTableView associated with this TreeTableCell
  - updateTreeTableRow
```
public final void updateTreeTableRow(TreeTableRow<S> treeTableRow)
```
    Updates the TreeTableRow associated with this TreeTableCell. Note: This function is intended to be used by experts, primarily by those implementing new Skins. It is not common for developers or designers to access this function directly.
    
    Parameters:
    
    treeTableRow - the TreeTableRow associated with this TreeTableCell
  - updateTreeTableColumn
```
public final void updateTreeTableColumn(TreeTableColumn<S,T> col)
```
    Updates the TreeTableColumn associated with this TreeTableCell. Note: This function is intended to be used by experts, primarily by those implementing new Skins. It is not common for developers or designers to access this function directly.
    
    Parameters:
    
    col - the TreeTableColumn associated with this TreeTableCell
  - createDefaultSkin
```
protected Skin<?> createDefaultSkin()
```
    Create a new instance of the default skin for this control. This is called to create a skin for the control if no skin is provided via CSS -fx-skin or set explicitly in a sub-class with setSkin(...).
    
    Overrides:
    
    createDefaultSkin in class Control
    
    Returns:
    
    new instance of default skin for this control. If null then the control will have no skin unless one is provided by css.
