public class Accordion
extends Control

An accordion is a group of TitlePanes. Only one TitledPane can be opened at a time.

The TitledPane content in an accordion can be any Node such as UI controls or groups of nodes added to a layout container.

It is not recommended to set the MinHeight, PrefHeight, or MaxHeight for this control. Unexpected behavior will occur because the Accordion's height changes when a TitledPane is opened or closed.

Accordion sets focusTraversable to false.

Example:

 TitledPane t1 = new TitledPane("T1", new Button("B1"));
 TitledPane t2 = new TitledPane("T2", new Button("B2"));
 TitledPane t3 = new TitledPane("T3", new Button("B3"));
 Accordion accordion = new Accordion();
 accordion.getPanes().addAll(t1, t2, t3);

Property Details

expandedPane

public final ObjectProperty<TitledPane> expandedPaneProperty
The expanded TitledPane in the Accordion.
See Also:
getExpandedPane(), setExpandedPane(TitledPane)

Constructor Details

Accordion

public Accordion()
Creates a new Accordion with no TitledPanes.

Accordion

public Accordion(TitledPane... titledPanes)
Creates a new Accordion with the given TitledPanes showing within it.
Parameters:
titledPanes - The TitledPanes to show inside the Accordion.
Since:
JavaFX 8u40

Method Details

setExpandedPane

public final void setExpandedPane(TitledPane value)

The expanded TitledPane that is currently visible. While it is technically possible to set the expanded pane to a value that is not in getPanes(), doing so will be treated by the skin as if expandedPane is null. If a pane is set as the expanded pane, and is subsequently removed from getPanes(), then expanded pane will be set to null, if possible. (This will not be possible if you have manually bound the expanded pane to some value, for example).

Parameters:
value - the expanded TitledPane

getExpandedPane

public final TitledPane getExpandedPane()
Gets the expanded TitledPane in the Accordion. If the expanded pane has been removed or there is no expanded TitledPane null is returned.
Returns:
The expanded TitledPane in the Accordion.

expandedPaneProperty

public final ObjectProperty<TitledPane> expandedPaneProperty()
The expanded TitledPane in the Accordion.
See Also:
getExpandedPane(), setExpandedPane(TitledPane)

getPanes

public final ObservableList<TitledPane> getPanes()
Gets the list of TitledPane in this Accordion. Changing this ObservableList will immediately result in the Accordion updating to display the new contents of this ObservableList.
Returns:
The list of TitledPane in this Accordion.

getInitialFocusTraversable

protected Boolean getInitialFocusTraversable()
Returns the initial focus traversable state of this control, for use by the JavaFX CSS engine to correctly set its initial value. This method is overridden as by default UI controls have focus traversable set to true, but that is not appropriate for this control.
Overrides:
getInitialFocusTraversable in class Control
Returns:
the initial focus traversable state of this control
