## Class BorderStroke

- java.lang.Object
- - javafx.scene.layout.BorderStroke

-     public class BorderStroke
      extends Object

  Defines the stroke to use on a `Border` for styling a `Region`. The stroke is a vector-based rendering that outlines the border area. It can be inset (or outset) from the `Region`'s edge, and the values of the stroke are taken into account when computing the `Region`'s insets (for defining the content area). The stroke visuals are not used when any `BorderImage`s are in use.

  When applied to a `Region` with a defined shape, the border width and stroking information for the `top` is used, while the other attributes are ignored.

  Since:
    JavaFX 8.0
