T - The type of the elements contained within the TableColumn.public class ChoiceBoxTableCell<S,T> extends TableCell<S,T>
TableCell implementation that draws a
ChoiceBox node inside the cell.
By default, the ChoiceBoxTableCell is rendered as a Label when not
being edited, and as a ChoiceBox when in editing mode. The ChoiceBox will, by
default, stretch to fill the entire table cell.
To create a ChoiceBoxTableCell, it is necessary to provide zero or more
items that will be shown to the user when the ChoiceBox menu is
showing. These items must be of the same type as the TableColumn.

ChoiceBoxTableCell()
Creates a default ChoiceBoxTableCell with an empty items list.

visuals of the cell.

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
