Type Parameters:

T - The type of the elements contained within the TreeView.

All Implemented Interfaces:

Styleable, EventTarget, Skinnable

public class TextFieldTreeCell<T>
extends TreeCell<T>

A class containing a TreeCell implementation that draws a TextField node inside the cell.

By default, the TextFieldTreeCell is rendered as a Label when not being edited, and as a TextField when in editing mode. The TextField will, by default, stretch to fill the entire tree cell.

Since:

JavaFX 2.2

Property Details

converter

public final ObjectProperty<StringConverter<T>> converterProperty

The StringConverter property.

See Also:

• getConverter()
• setConverter(StringConverter)
• converterProperty()

Constructor Details

TextFieldTreeCell

public TextFieldTreeCell()

Creates a default TextFieldTreeCell with a null converter. Without a StringConverter specified, this cell will not be able to accept input from the TextField (as it will not know how to convert this back to the domain object). It is therefore strongly encouraged to not use this constructor unless you intend to set the converter separately.

TextFieldTreeCell

public TextFieldTreeCell(StringConverter<T> converter)

Creates a TextFieldTreeCell that provides a TextField when put into editing mode that allows editing of the cell content. This method will work on any TreeView instance, regardless of its generic type. However, to enable this, a StringConverter must be provided that will convert the given String (from what the user typed in) into an instance of type T. This item will then be passed along to the TreeView.onEditCommitProperty() callback.

Parameters:

converter - A converter that can convert the given String (from what the user typed in) into an instance of type T.

Method Details

forTreeView

public static Callback<TreeView<String>,TreeCell<String>> forTreeView()

Provides a TextField that allows editing of the cell content when the cell is double-clicked, or when TreeView.edit(javafx.scene.control.TreeItem) is called. This method will only work on TreeView instances which are of type String.

Returns:

A Callback that can be inserted into the cell factory property of a TreeView, that enables textual editing of the content.

forTreeView

public static <T> Callback<TreeView<T>,TreeCell<T>> forTreeView(StringConverter<T> converter)

Provides a TextField that allows editing of the cell content when the cell is double-clicked, or when TreeView.edit(javafx.scene.control.TreeItem) is called. This method will work on any TreeView instance, regardless of its generic type. However, to enable this, a StringConverter must be provided that will convert the given String (from what the user typed in) into an instance of type T. This item will then be passed along to the TreeView.onEditCommitProperty() callback.

Type Parameters:

T - The type of the elements contained within the TreeView

Parameters:

converter - A StringConverter that can convert the given String (from what the user typed in) into an instance of type T.

Returns:

A Callback that can be inserted into the cell factory property of a TreeView, that enables textual editing of the content.

converterProperty

public final ObjectProperty<StringConverter<T>> converterProperty()

The StringConverter property.

Returns:

the StringConverter property

See Also:

• getConverter()
• setConverter(StringConverter)

setConverter

public final void setConverter(StringConverter<T> value)

Sets the StringConverter to be used in this cell.

Parameters:

value - the StringConverter to be used in this cell

getConverter

public final StringConverter<T> getConverter()

Returns the StringConverter used in this cell.

Returns:

the StringConverter used in this cell

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:

1. 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.
2. 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.

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.
