Class BorderStroke

java.lang.Object
javafx.scene.layout.BorderStroke
All Implemented Interfaces:
Interpolatable<BorderStroke>
public final class BorderStroke extends Object implements Interpolatable<BorderStroke>
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

    • interpolate

      public BorderStroke interpolate(BorderStroke endValue, double t)
      Returns an intermediate value between the value of this Interpolatable and the specified endValue using the linear interpolation factor t. The interpolation factor can be any finite value.

      The returned value might not be a new instance; the implementation might also return one of the two existing instances if the intermediate value would be equal to one of the existing values. However, this is an optimization and applications should not assume any particular identity of the returned value.

      Specified by:
      interpolate in interface Interpolatable<BorderStroke>
      Parameters:
      endValue - the target value
      t - the interpolation factor
      Returns:
      the intermediate value
      Throws:
      NullPointerException - if endValue is null
