JavaFX 25 · javafx.scene.control.Accordion · APIdia, the JavaDoc alternative

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 javafx.scene.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);

createDefaultSkin	back to summary
protected Skin<?> createDefaultSkin() Overrides javafx.scene.control.Control.createDefaultSkin. Doc from javafx.scene.control.Control.createDefaultSkin. Create a new instance of the default skin for this control. This is called to create a skin for the control if no skin is provided via CSS `-fx-skin` or set explicitly in a sub-class with `setSkin(...)`. Annotations @Override

protected Skin<?> createDefaultSkin()

Overrides javafx.scene.control.Control.createDefaultSkin.

Doc from javafx.scene.control.Control.createDefaultSkin.

expandedPaneProperty

back to summary

public final ObjectProperty<TitledPane> expandedPaneProperty()

The expanded TitledPane in the Accordion.

Returns:ObjectProperty<TitledPane>: The expanded TitledPane in the Accordion.

getContentBias	back to summary
public Orientation getContentBias() Overrides javafx.scene.Node.getContentBias. Doc from javafx.scene.Node.getContentBias. Returns the orientation of a node's resizing bias for layout purposes. If the node type has no bias, returns null. If the node is resizable and it's height depends on its width, returns HORIZONTAL, else if its width depends on its height, returns VERTICAL. Resizable subclasses should override this method to return an appropriate value. Annotations @Override

getExpandedPane	back to summary
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:TitledPane The expanded TitledPane in the Accordion.

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:TitledPane: The expanded TitledPane in the Accordion.

getInitialFocusTraversable	back to summary
protected Boolean getInitialFocusTraversable() Overrides javafx.scene.control.Control.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. Annotations @Override Since 9

requestLayout	back to summary
public void requestLayout() Overrides javafx.scene.Parent.requestLayout. Doc from javafx.scene.Parent.requestLayout. Requests a layout pass to be performed before the next scene is rendered.

setExpandedPane back to summary

setExpandedPane	back to summary
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:TitledPane the expanded `TitledPane`

public final void setExpandedPane(TitledPane value)
