Class BorderWidths

java.lang.Object
javafx.scene.layout.BorderWidths
public final class BorderWidths
extends Object
Defines widths for four components (top, right, bottom, and left). Each width is defined as a non-negative value. This value might be interpreted either as an literal value, or as a percentage of the width or height of the Region, depending on the values for topAsPercentage, rightAsPercentage, bottomAsPercentage, leftAsPercentage. The only allowable negative value for top, right, bottom, and left is AUTO.

Because the BorderWidths is immutable, it can safely be used in any cache, and can safely be reused among multiple Regions.

Since:
JavaFX 8.0
