Class 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 BorderImages 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
