Class ChoiceBoxTableCell<S,T>

javafx.scene.control.cell.ChoiceBoxTableCell<S,T>

Type Parameters:: S - The type of the TableView generic type; T - The type of the elements contained within the TableColumn.

All Implemented Interfaces:: Styleable, EventTarget, Skinnable

public class ChoiceBoxTableCell<S,T> extends TableCell<S,T>

A class containing a 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.

Since:: JavaFX 2.2

updateItem

public void updateItem(T item, boolean empty)

The updateItem method should not be called by developers, but it is the best method for developers to override to allow for them to customise the visuals of the cell. To clarify, developers should never call this method in their code (they should leave it up to the UI control, such as the 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:

We call the super.updateItem(T, boolean) method. If this is not done, the item and empty properties are not correctly set, and you are likely to end up with graphical issues.
We test for the 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.

Overrides:: updateItem in class Cell<T>
Parameters:: 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.
