T - The type of the elements contained within the TreeTableColumn.public class CheckBoxTreeTableCell<S,T> extends TreeTableCell<S,T>
TreeTableCell implementation that draws a
CheckBox node inside the cell, optionally with a label to indicate
what the checkbox represents.
By default, the CheckBoxTreeTableCell is rendered with a CheckBox centred in
the TreeTableColumn. If a label is required, it is necessary to provide a
non-null StringConverter instance to the
CheckBoxTreeTableCell(Callback, StringConverter) constructor.
To construct an instance of this class, it is necessary to provide a
Callback that, given an object of type T, will return an
ObservableProperty<Boolean> that represents whether the given item is
selected or not. This ObservableValue will be bound bidirectionally (meaning
that the CheckBox in the cell will set/unset this property based on user
interactions, and the CheckBox will reflect the state of the ObservableValue,
if it changes externally).
Note that the CheckBoxTreeTableCell renders the CheckBox 'live', meaning that
the CheckBox is always interactive and can be directly toggled by the user.
This means that it is not necessary that the cell enter its
editing state (usually by the user double-clicking
on the cell). A side-effect of this is that the usual editing callbacks
(such as on edit commit)
will not be called. If you want to be notified of changes,
it is recommended to directly observe the boolean properties that are
manipulated by the CheckBox.

the TreeTableCell beside the CheckBox. By default a label is not
shown, but by setting this to true the item in the cell will also
have toString() called on it. If this is not the desired behavior,
consider using

given row item.Callback that will return a TreeTableCell that is

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:
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.updateItem in class Cell<T>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.Submit a bug or feature
