  • cellValueFactory

    public final ObjectProperty<Callback<TreeTableColumn.CellDataFeatures<S,T>,ObservableValue<T>>> cellValueFactoryProperty

    The cell value factory needs to be set to specify how to populate all cells within a single TreeTableColumn. A cell value factory is a Callback that provides a TreeTableColumn.CellDataFeatures instance, and expects an ObservableValue to be returned. The returned ObservableValue instance will be observed internally to allow for updates to the value to be immediately reflected on screen.

    An example of how to set a cell value factory is:

    firstNameCol.setCellValueFactory(new Callback<CellDataFeatures<Person, String>, ObservableValue<String>>() {
         public ObservableValue<String> call(CellDataFeatures<Person, String> p) {
             // p.getValue() returns the TreeItem<Person> instance for a particular TreeTableView row,
             // p.getValue().getValue() returns the Person instance inside the TreeItem<Person>
             return p.getValue().getValue().firstNameProperty();
         }
      });
     }

    A common approach is to want to populate cells in a TreeTableColumn using a single value from a Java bean. To support this common scenario, there is the TreeItemPropertyValueFactory class. Refer to this class for more information on how to use it, but briefly here is how the above use case could be simplified using the TreeItemPropertyValueFactory class:

    firstNameCol.setCellValueFactory(new TreeItemPropertyValueFactory<Person,String>("firstName"));

    See Also:

    getCellValueFactory(), setCellValueFactory(Callback)

  • cellFactory

    public final ObjectProperty<Callback<TreeTableColumn<S,T>,TreeTableCell<S,T>>> cellFactoryProperty

    The cell factory for all cells in this column. The cell factory is responsible for rendering the data contained within each TreeTableCell for a single TreeTableColumn.

    By default TreeTableColumn uses a default cell factory, but this can be replaced with a custom implementation, for example to show data in a different way or to support editing. There is a lot of documentation on creating custom cell factories elsewhere (see Cell and TreeTableView for example).

    Finally, there are a number of pre-built cell factories available in the javafx.scene.control.cell package.

    See Also:

    getCellFactory(), setCellFactory(Callback)

  • sortType

    public final ObjectProperty<TreeTableColumn.SortType> sortTypeProperty

    Used to state whether this column, if it is part of a sort order (see TreeTableView.getSortOrder() for more details), should be sorted in ascending or descending order. Simply toggling this property will result in the sort order changing in the TreeTableView, assuming of course that this column is in the sortOrder ObservableList to begin with.

  • onEditStart

• Field Detail

  • DEFAULT_CELL_FACTORY

    public static final Callback<TreeTableColumn<?,?>,TreeTableCell<?,?>> DEFAULT_CELL_FACTORY

    If no cellFactory is specified on a TreeTableColumn instance, then this one will be used by default. At present it simply renders the TableCell item property within the graphic property if the item is a Node, or it simply calls toString() if it is not null, setting the resulting string inside the text property.

  • getColumns

    public final ObservableList<TreeTableColumn<S,?>> getColumns()

    This enables support for nested columns, which can be useful to group together related data. For example, we may have a 'Name' column with two nested columns for 'First' and 'Last' names.

    This has no impact on the table as such - all column indices point to the leaf columns only, and it isn't possible to sort using the parent column, just the leaf columns. In other words, this is purely a visual feature.

    Specified by:

    getColumns in class TableColumnBase<TreeItem<S>,T>

    Returns:

    An ObservableList containing TableColumnBase instances (or subclasses) that are the children of this TableColumnBase. If these children TableColumnBase instances are set as visible, they will appear beneath this table column.

  • getCellObservableValue

    public final ObservableValue<T> getCellObservableValue(int index)

    Attempts to return an ObservableValue<T> for the item in the given index (which is of type S). In other words, this method expects to receive an integer value that is greater than or equal to zero, and less than the size of the underlying data model. If the index is valid, this method will return an ObservableValue<T> for this specific column.

    This is achieved by calling the cell value factory, and returning whatever it returns when passed a CellDataFeatures (see, for example, the CellDataFeatures classes belonging to TableColumn and TreeTableColumn for more information).

    Specified by:

    getCellObservableValue in class TableColumnBase<TreeItem<S>,T>

    Parameters:

    index - The index of the item (of type S) for which an ObservableValue<T> is sought.

    Returns:

    An ObservableValue<T> for this specific table column.

  • getCellObservableValue

    public final ObservableValue<T> getCellObservableValue(TreeItem<S> item)

    Attempts to return an ObservableValue<T> for the given item (which is of type S). In other words, this method expects to receive an object from the underlying data model for the entire 'row' in the table, and it must return an ObservableValue<T> for the value in this specific column.

    This is achieved by calling the cell value factory, and returning whatever it returns when passed a CellDataFeatures (see, for example, the CellDataFeatures classes belonging to TableColumn and TreeTableColumn for more information).

    Specified by:

    getCellObservableValue in class TableColumnBase<TreeItem<S>,T>

    Parameters:

    item - The item (of type S) for which an ObservableValue<T> is sought.

    Returns:

    An ObservableValue<T> for this specific table column.

  • getTypeSelector

    public String getTypeSelector()

    The type of this Styleable that is to be used in selector matching. This is analogous to an "element" in HTML. (CSS Type Selector).

    Returns:

    "TreeTableColumn"

  • getStyleableParent

    public Styleable getStyleableParent()
