Class TableColumn<S,T>

java.lang.Object

javafx.scene.control.TableColumnBase<S,T>

javafx.scene.control.TableColumn<S,T>

Type Parameters:

S - The type of the TableView generic type (i.e. S == TableView<S>)

T - The type of the content in all cells in this TableColumn.

All Implemented Interfaces:

Styleable, EventTarget

public class TableColumn<S,T>
extends TableColumnBase<S,T>
implements EventTarget

A TableView is made up of a number of TableColumn instances. Each TableColumn in a table is responsible for displaying (and editing) the contents of that column. As well as being responsible for displaying and editing data for a single column, a TableColumn also contains the necessary properties to:

• Be resized (using minWidth/prefWidth/maxWidth and width properties)
• Have its visibility toggled
• Display header text
• Display any nested columns it may contain
• Have a context menu when the user right-clicks the column header area
• Have the contents of the table be sorted (using comparator, sortable and sortType)

When creating a TableColumn instance, perhaps the two most important properties to set are the column text (what to show in the column header area), and the column cell value factory (which is used to populate individual cells in the column). This can be achieved using some variation on the following code:

  
 ObservableList<Person> data = ...
 TableView<Person> tableView = new TableView<Person>(data);
 
 TableColumn<Person,String> firstNameCol = new TableColumn<Person,String>("First Name");
 firstNameCol.setCellValueFactory(new Callback<CellDataFeatures<Person, String>, ObservableValue<String>>() {
     public ObservableValue<String> call(CellDataFeatures<Person, String> p) {
         // p.getValue() returns the Person instance for a particular TableView row
         return p.getValue().firstNameProperty();
     }
  });
 
 tableView.getColumns().add(firstNameCol);}

This approach assumes that the object returned from p.getValue() has a JavaFX ObservableValue that can simply be returned. The benefit of this is that the TableView will internally create bindings to ensure that, should the returned ObservableValue change, the cell contents will be automatically refreshed.

In situations where a TableColumn must interact with classes created before JavaFX, or that generally do not wish to use JavaFX apis for properties, it is possible to wrap the returned value in a ReadOnlyObjectWrapper instance. For example:

  
 firstNameCol.setCellValueFactory(new Callback<CellDataFeatures<Person, String>, ObservableValue<String>>() {
     public ObservableValue<String> call(CellDataFeatures<Person, String> p) {
         return new ReadOnlyObjectWrapper(p.getValue().getFirstName());
     }
  });

It is hoped that over time there will be convenience cell value factories developed and made available to developers. As of the JavaFX 2.0 release, there is one such convenience class: PropertyValueFactory. This class removes the need to write the code above, instead relying on reflection to look up a given property from a String. Refer to the PropertyValueFactory class documentation for more information on how to use this with a TableColumn. Finally, for more detail on how to use TableColumn, there is further documentation in the TableView class documentation.

Since:

JavaFX 2.0

cellValueFactory

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

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

 lastNameCol.setCellValueFactory(new Callback<CellDataFeatures<Person, String>, ObservableValue<String>>() {
     public ObservableValue<String> call(CellDataFeatures<Person, String> p) {
         // p.getValue() returns the Person instance for a particular TableView row
         return p.getValue().lastNameProperty();
     }
  });
 }
 

A common approach is to want to populate cells in a TableColumn using a single value from a Java bean. To support this common scenario, there is the PropertyValueFactory 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 PropertyValueFactory class:

 lastNameCol.setCellValueFactory(new PropertyValueFactory<Person,String>("lastName"));
 

See Also:

getCellValueFactory(), setCellValueFactory(Callback)

cellFactory

public final ObjectProperty<Callback<TableColumn<S,T>,TableCell<S,T>>> cellFactoryProperty

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

By default TableColumn uses the 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 TableView for example).

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

sortType

public final ObjectProperty<TableColumn.SortType> sortTypeProperty

Used to state whether this column, if it is part of a sort order (see TableView.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 TableView, assuming of course that this column is in the sortOrder ObservableList to begin with.

DEFAULT_CELL_FACTORY

public static final Callback<TableColumn<?,?>,TableCell<?,?>> DEFAULT_CELL_FACTORY

getColumns

public final ObservableList<TableColumn<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<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<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(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<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).

Specified by:

getTypeSelector in interface Styleable

Returns:

"TableColumn"

public Styleable getStyleableParent()

Return the parent of this Styleable, or null if there is no parent.
