T - The type of the elements contained within the TreeView TreeItem
instances.public class CheckBoxTreeCell<T> extends TreeCell<T>
TreeCell implementation that draws a
CheckBox node inside the cell, along with support for common
interactions (discussed in more depth shortly).
To make creating TreeViews with CheckBoxes easier, a convenience class
called CheckBoxTreeItem is provided. It is highly recommended
that developers use this class, rather than the regular TreeItem
class, when constructing their TreeView tree structures. Refer to the
CheckBoxTreeItem API documentation for an example on how these two classes
can be combined.
When used in a TreeView, the CheckBoxCell is rendered with a CheckBox to
the right of the 'disclosure node' (i.e. the arrow). The item stored in
TreeItem.getValue() will then have the StringConverter called
on it, and this text will take all remaining horizontal space. Additionally,
by using CheckBoxTreeItem, the TreeView will automatically handle
situations such as:
CheckBox beside an item that has children will
result in all children also becoming selected/unselected.
CheckBox beside an item that has a parent will
possibly toggle the state of the parent. For example, if you select a
single child, the parent will become indeterminate (indicating partial
selection of children). If you proceed to select all children, the
parent will then show that it too is selected. This is recursive, with
all parent nodes updating as expected.
CheckBoxTreeItem is not desirable,
then it is necessary to call one of the constructors where a Callback
is provided that can return an ObservableValue<Boolean>
given a TreeItem instance. This ObservableValue<Boolean>
should represent the boolean state of the given TreeItem.
Note that the CheckBoxTreeCell 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.

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.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
