Type Parameters:

public class CheckBoxTreeTableCell<S,T>
extends TreeTableCell<S,T>

A class containing a 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).

Constructor Detail

CheckBoxTreeTableCell

public CheckBoxTreeTableCell()

Creates a default CheckBoxTreeTableCell.

CheckBoxTreeTableCell

public CheckBoxTreeTableCell(Callback<java.lang.Integer,ObservableValue<java.lang.Boolean>> getSelectedProperty)

Creates a default CheckBoxTreeTableCell with a custom Callback to retrieve an ObservableValue for a given cell index.

Parameters:

getSelectedProperty - A Callback that will return an ObservableValue given an index from the TreeTableColumn.

CheckBoxTreeTableCell

public CheckBoxTreeTableCell(Callback<java.lang.Integer,ObservableValue<java.lang.Boolean>> getSelectedProperty,
                             StringConverter<T> converter)

Creates a CheckBoxTreeTableCell with a custom string converter.

Method Detail

forTreeTableColumn

public static <S> Callback<TreeTableColumn<S,java.lang.Boolean>,TreeTableCell<S,java.lang.Boolean>> forTreeTableColumn(TreeTableColumn<S,java.lang.Boolean> column)

Creates a cell factory for use in a TreeTableColumn cell factory. This method requires that the TreeTableColumn be of type <code>Boolean</code>.

When used in a TreeTableColumn, the CheckBoxCell is rendered with a CheckBox centered in the column.

The ObservableValue<Boolean> contained within each cell in the column will be bound bidirectionally. This means 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<Boolean>, if it changes externally).

Returns:

A Callback that will return a TreeTableCell that is able to work on the type of element contained within the TreeTableColumn.

forTreeTableColumn

public static <S,T> Callback<TreeTableColumn<S,T>,TreeTableCell<S,T>> forTreeTableColumn(Callback<java.lang.Integer,ObservableValue<java.lang.Boolean>> getSelectedProperty)

Creates a cell factory for use in a TreeTableColumn cell factory. This method requires that the TreeTableColumn be of type ObservableValue<Boolean>.

When used in a TreeTableColumn, the CheckBoxCell is rendered with a CheckBox centered in the column.

Type Parameters:

T - The type of the elements contained within the TreeTableColumn instance.

Parameters:

getSelectedProperty - A Callback that, given an object of type TreeTableColumn<S,T>, will return an ObservableValue<Boolean> that represents whether the given item is selected or not. This ObservableValue<Boolean> 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<Boolean>, if it changes externally).

Returns:

A Callback that will return a TreeTableCell that is able to work on the type of element contained within the TreeTableColumn.

forTreeTableColumn

public static <S,T> Callback<TreeTableColumn<S,T>,TreeTableCell<S,T>> forTreeTableColumn(Callback<java.lang.Integer,ObservableValue<java.lang.Boolean>> getSelectedProperty,
                                                                                         boolean showLabel)

Creates a cell factory for use in a TreeTableColumn cell factory. This method requires that the TreeTableColumn be of type ObservableValue<Boolean>.

When used in a TreeTableColumn, the CheckBoxCell is rendered with a CheckBox centered in the column.

Type Parameters:

T - The type of the elements contained within the TreeTableColumn instance.

Parameters:

getSelectedProperty - A Callback that, given an object of type TreeTableColumn<S,T>, will return an ObservableValue<Boolean> that represents whether the given item is selected or not. This ObservableValue<Boolean> 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<Boolean>, if it changes externally).

showLabel - In some cases, it may be desirable to show a label in 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 forTreeTableColumn(javafx.util.Callback, javafx.util.StringConverter), which allows for you to provide a callback that specifies the label for a given row item.

Returns:

A Callback that will return a TreeTableCell that is able to work on the type of element contained within the TreeTableColumn.

forTreeTableColumn

public static <S,T> Callback<TreeTableColumn<S,T>,TreeTableCell<S,T>> forTreeTableColumn(Callback<java.lang.Integer,ObservableValue<java.lang.Boolean>> getSelectedProperty,
                                                                                         StringConverter<T> converter)

Creates a cell factory for use in a TreeTableColumn cell factory. This method requires that the TreeTableColumn be of type ObservableValue<Boolean>.

When used in a TreeTableColumn, the CheckBoxCell is rendered with a CheckBox centered in the column.

Type Parameters:

T - The type of the elements contained within the TreeTableColumn instance.

Parameters:

getSelectedProperty - A Callback that, given an object of type TreeTableColumn<S,T>, will return an ObservableValue<Boolean> that represents whether the given item is selected or not. This ObservableValue<Boolean> 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<Boolean>, if it changes externally).

converter - A StringConverter that, give an object of type T, will return a String that can be used to represent the object visually. The default implementation in forTreeTableColumn(Callback, boolean) (when showLabel is true) is to simply call .toString() on all non-null items (and to just return an empty string in cases where the given item is null).

Returns:

A Callback that will return a TreeTableCell that is able to work on the type of element contained within the TreeTableColumn.

converterProperty

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

The StringConverter property.

setConverter

public final void setConverter(StringConverter<T> value)

Sets the StringConverter to be used in this cell.

getConverter

public final StringConverter<T> getConverter()

Returns the StringConverter used in this cell.

selectedStateCallbackProperty

public final ObjectProperty<Callback<java.lang.Integer,ObservableValue<java.lang.Boolean>>> selectedStateCallbackProperty()

Property representing the Callback that is bound to by the CheckBox shown on screen.

See Also:

getSelectedStateCallback(), setSelectedStateCallback(Callback)

setSelectedStateCallback

public final void setSelectedStateCallback(Callback<java.lang.Integer,ObservableValue<java.lang.Boolean>> value)

Sets the Callback that is bound to by the CheckBox shown on screen.

getSelectedStateCallback

public final Callback<java.lang.Integer,ObservableValue<java.lang.Boolean>> getSelectedStateCallback()

Returns the Callback that is bound to by the CheckBox shown on screen.

updateItem

public void updateItem(T item,
                       boolean empty)

Updates the item associated with this Cell. This method should only be called by Skin implementations of ListView, TableView, TreeView, or other controls using Cells. It is not intended to be called by application developers.

Because null is a perfectly valid value in the application domain, Cell needs some way to distinguish whether or not the cell actually holds a value. The empty flag indicates this. It is an error to supply a non-null item but a true value for empty.

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.
