JavaFX: BorderPane

BorderPane lays out children in top, left, right, bottom, and center positions.

 

a.   The top and bottom children will be resized to their preferred heights and extend the width of the border pane.

b.   The left and right children will be resized to their preferred widths and extend the length between the top and bottom nodes.

c.    The center node will be resized to fill the available space in the middle.

 

BorderPane class provides following constructors to define BorderPane instance.

 

public BorderPane()

public BorderPane(Node center)

public BorderPane(Node center, Node top, Node right, Node bottom, Node left)

center: specifies the node to set as the center of the BorderPane.

top: specifies the node to set as the top of the BorderPane.

right: specifies the node to set as the right of the BorderPane.

bottom: specifies the node to set as the bottom of the BorderPane.

left: specifies the node to set as the left of the BorderPane.
