public class Separator
extends Control
A horizontal or vertical separator line. The visual appearance of this separator can be controlled via CSS. A horizontal separator occupies the full horizontal space allocated to it (less padding), and a vertical separator occupies the full vertical space allocated to it (less padding). The halignment and valignment properties determine how the separator is positioned in the other dimension, for example, how a horizontal separator is positioned vertically within its allocated space.

The separator is horizontal (i.e. isVertical() == false) by default.

The style-class for this control is "separator".

The separator provides two pseudo-classes "horizontal" and "vertical" which are mutually exclusive. The "horizontal" pseudo-class applies if the separator is horizontal, and the "vertical" pseudo-class applies if the separator is vertical.

Separator sets focusTraversable to false.

Example: 

 Button b0 = new Button("Button 0");
 Button b1 = new Button("Button 1");
 Button b2 = new Button("Button 2");
 Button b3 = new Button("Button 3");
 Separator separator = new Separator(Orientation.HORIZONTAL);
 VBox vBox = new VBox(b0, b1, separator, b2, b3);

    • createDefaultSkin

      protected Skin<?> 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(...).

      createDefaultSkin in class Control
      Returns:
      new instance of default skin for this control. If null then the control will have no skin unless one is provided by css.

    • getClassCssMetaData

      public static List<CssMetaData<? extends Styleable,​?>> getClassCssMetaData()
      Returns:
      The CssMetaData associated with this class, which may include the CssMetaData of its superclasses.

    • 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
