javafx.scene.control.cell.TextFieldTableCell<S,T>

Type Parameters:
  `S` - The type of the TableView generic type
  `T` - The type of the elements contained within the TableColumn.

All Implemented Interfaces:
  `Styleable`, `EventTarget`, `Skinnable`

public class TextFieldTableCell<S,T> extends TableCell<S,T>
A class containing a `TableCell` implementation that draws a `TextField` node inside the cell.

By default, the TextFieldTableCell is rendered as a `Label` when not being edited, and as a TextField when in editing mode. The TextField will, by default, stretch to fill the entire table cell.

Since:
  JavaFX 2.2

- ## Property Details

  - ### converter

    public final ObjectProperty<StringConverter<T>> converterProperty
    The `StringConverter` property.
    See Also:
      - `getConverter()`
      - `setConverter(StringConverter)`
      - `converterProperty()`

- ## Constructor Details

  - ### TextFieldTableCell

    public TextFieldTableCell()
    Creates a default TextFieldTableCell with a null converter. Without a `StringConverter` specified, this cell will not be able to accept input from the TextField (as it will not know how to convert this back to the domain object). It is therefore strongly encouraged to not use this constructor unless you intend to set the converter separately.

  - ### TextFieldTableCell

    public TextFieldTableCell(StringConverter<T> converter)
    Creates a TextFieldTableCell that provides a `TextField` when put into editing mode that allows editing of the cell content. This method will work on any TableColumn instance, regardless of its generic type. However, to enable this, a `StringConverter` must be provided that will convert the given String (from what the user typed in) into an instance of type T. This item will then be passed along to the `TableColumn.onEditCommitProperty()` callback.
    Parameters:
      `converter` - A `converter` that can convert the given String (from what the user typed in) into an instance of type T.

- ## Method Details

  - ### forTableColumn

    public static <S> Callback<TableColumn<S,String>,TableCell<S,String>> forTableColumn()
    Provides a `TextField` that allows editing of the cell content when the cell is double-clicked, or when `TableView.edit(int, javafx.scene.control.TableColumn)` is called. This method will only work on `TableColumn` instances which are of type String.
    Type Parameters:
      `S` - The type of the TableView generic type
    Returns:
      A `Callback` that can be inserted into the `cell factory property` of a TableColumn, that enables textual editing of the content.

  - ### forTableColumn

    public static <S, T> Callback<TableColumn<S,T>,TableCell<S,T>> forTableColumn(StringConverter<T> converter)
    Provides a `TextField` that allows editing of the cell content when the cell is double-clicked, or when `TableView.edit(int, javafx.scene.control.TableColumn)` is called. This method will work on any `TableColumn` instance, regardless of its generic type. However, to enable this, a `StringConverter` must be provided that will convert the given String (from what the user typed in) into an instance of type T. This item will then be passed along to the `TableColumn.onEditCommitProperty()` callback.
    Type Parameters:
      `S` - The type of the TableView generic type
      `T` - The type of the elements contained within the TableColumn
    Parameters:
      `converter` - A `StringConverter` that can convert the given String (from what the user typed in) into an instance of type T.
    Returns:
      A `Callback` that can be inserted into the `cell factory property` of a TableColumn, that enables textual editing of the content.

  - ### converterProperty

    public final ObjectProperty<StringConverter<T>> converterProperty()
    The `StringConverter` property.
    Returns:
      the `StringConverter` property
    See Also:
      - `getConverter()`
      - `setConverter(StringConverter)`

  - ### setConverter

    public final void setConverter(StringConverter<T> value)
    Sets the `StringConverter` to be used in this cell.
    Parameters:
      `value` - the `StringConverter` to be used in this cell

  - ### getConverter

    public final StringConverter<T> getConverter()
    Returns the `StringConverter` used in this cell.
    Returns:
      the `StringConverter` used in this cell

  - ### updateItem

    public void updateItem(T item, boolean empty)
    The updateItem method should not be called by developers, but it is the best method for developers to override to allow for them to customise the visuals of the cell. To clarify, developers should never call this method in their code (they should leave it up to the UI control, such as the `ListView` control) to call this method. However, the purpose of having the updateItem method is so that developers, when specifying custom cell factories (again, like the ListView `cell factory`), the updateItem method can be overridden to allow for complete customisation of the cell.

    It is very important that subclasses of Cell override the updateItem method properly, as failure to do so will lead to issues such as blank cells or cells with unexpected content appearing within them. Here is an example of how to properly override the updateItem method:

         protected void updateItem(T item, boolean empty) {
             super.updateItem(item, empty);

             if (empty || item == null) {
                 setText(null);
                 setGraphic(null);
             } else {
                 setText(item.toString());
             }
         }

    Note in this code sample two important points:

    1. We call the super.updateItem(T, boolean) method. If this is not done, the item and empty properties are not correctly set, and you are likely to end up with graphical issues.
    2. We test for the `empty` condition, and if true, we set the text and graphic properties to null. If we do not do this, it is almost guaranteed that end users will see graphical artifacts in cells unexpectedly.
    Overrides:
      `updateItem` in class `Cell<T>`
    Parameters:
      `item` - The new item for the cell.
      `empty` - whether or not this cell represents data from the list. If it is empty, then it does not represent any domain data, but is a cell being used to render an "empty" row.
