- 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 TreeTableColumn<S,T> extends TableColumnBase<TreeItem<S>,T> implements EventTarget
TreeTableView
is made up of a number of TreeTableColumn instances. Each
TreeTableColumn in a TreeTableView
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 TreeTableColumn also
contains the necessary properties to:
- Be resized (using
minWidth
/prefWidth
/maxWidth
andwidth
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
andsortType
)
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:
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();
}
});
}
This approach assumes that the object returned from p.getValue().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) {
// p.getValue() returns the TreeItem<Person> instance for a particular TreeTableView row,
// p.getValue().getValue() returns the Person instance inside the TreeItem<Person>
return new ReadOnlyObjectWrapper(p.getValue().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: TreeItemPropertyValueFactory
.
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
TreeItemPropertyValueFactory
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:

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 classTableColumnBase<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
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 aCellDataFeatures
(see, for example, the CellDataFeatures classes belonging toTableColumn
andTreeTableColumn
for more information).- Specified by:
getCellObservableValue
in classTableColumnBase<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
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 aCellDataFeatures
(see, for example, the CellDataFeatures classes belonging toTableColumn
andTreeTableColumn

- An ObservableValue<T> for this specific table column.

getTypeSelector
The type of thisStyleable
that is to be used in selector matching. This is analogous to an "element" in HTML. (CSS Type Selector).- Specified by:

in interfaceStyleable
- Returns:

-
getStyleableParent
Return the parent of this Styleable, or null if there is no parent.- Specified by:

-
getCssMetaData
The CssMetaData of this Styleable. This may be returned as an unmodifiable list.- Specified by:

in interfaceStyleable
- Returns:
- the CssMetaData
-
getClassCssMetaData
-
getStyleableNode
Returns the Node that represents this Styleable object. This method should be overridden in cases where the Styleable is not itself a Node, so that it may optionally return the relevant root node representation of itself. By default this method returns null, which can mean that either the Styleable itself is a Node, or if that is not the case, that the Styleable does not have a node representation available at the time of request.- Specified by:
getStyleableNode
in interfaceStyleable
- Returns:
- the Node that represents this Styleable object
