public class BorderPane extends Pane
BorderPane lays out children in top, left, right, bottom, and center positions.

The top and bottom children will be resized to their preferred heights and extend the width of the border pane. The left and right children will be resized to their preferred widths and extend the length between the top and bottom nodes. And the center node will be resized to fill the available space in the middle. Any of the positions may be null. Example:

         BorderPane borderPane = new BorderPane();
         ToolBar toolbar = new ToolBar();
         HBox statusbar = new HBox();
         Node appContent = new AppContentNode();
         borderPane.setTop(toolbar);
         borderPane.setCenter(appContent);
         borderPane.setBottom(statusbar);

Borderpanes may be styled with backgrounds and borders using CSS. See `Region` superclass for details.

BorderPane honors the minimum, preferred, and maximum sizes of its children. If the child's resizable range prevents it from be resized to fit within its position, it will be aligned relative to the space using a default alignment as follows:

- top: Pos.TOP_LEFT
- bottom: Pos.BOTTOM_LEFT
- left: Pos.TOP_LEFT
- right: Pos.TOP_RIGHT
- center: Pos.CENTER

See "Optional Layout Constraints" on how to customize these alignments.

BorderPane lays out each child set in the five positions regardless of the child's visible property value; unmanaged children are ignored.

## Resizable Range

BorderPane is commonly used as the root of a `Scene`, in which case its size will track the size of the scene. If the scene or stage size has not been directly set by the application, the scene size will be initialized to the border pane's preferred size. However, if a border pane has a parent other than the scene, that parent will resize the border pane within the border pane's resizable range during layout. By default the border pane computes this range based on its content as outlined in the table below.

BorderPane Resize Table
| width | height
minimum | left/right insets plus width required to display right/left children at their pref widths and top/bottom/center with at least their min widths | top/bottom insets plus height required to display top/bottom children at their pref heights and left/right/center with at least their min heights
preferred | left/right insets plus width required to display top/right/bottom/left/center children with at least their pref widths | top/bottom insets plus height required to display top/right/bottom/left/center children with at least their pref heights
maximum | Double.MAX_VALUE | Double.MAX_VALUE

A border pane's unbounded maximum width and height are an indication to the parent that it may be resized beyond its preferred size to fill whatever space is assigned to it.

BorderPane provides properties for setting the size range directly. These properties default to the sentinel value Region.USE_COMPUTED_SIZE, however the application may set them to other values as needed:

         borderPane.setPrefSize(500,400);

Applications may restore the computed values by setting these properties back to Region.USE_COMPUTED_SIZE.

BorderPane does not clip its content by default, so it is possible that children's bounds may extend outside its own bounds if a child's min size prevents it from being fit within it space.

## Optional Layout Constraints

An application may set constraints on individual children to customize BorderPane's layout. For each constraint, BorderPane provides a static method for setting it on the child.

BorderPane Constraint Table
Constraint | Type | Description
--- | --- | ---
alignment | javafx.geometry.Pos | The alignment of the child within its area of the border pane.
margin | javafx.geometry.Insets | Margin space around the outside of the child.

Example:

         ListView list = new ListView();
         BorderPane.setAlignment(list, Pos.TOP_LEFT);
         BorderPane.setMargin(list, new Insets(12,12,12,12));
         borderPane.setCenter(list);

    Property description:
      The node placed on the left edge of this border pane. If resizable, it will be resized to its preferred width and it's height will span the height of the border pane between the top and bottom nodes. If the node cannot be resized to fill the left space (it's not resizable or its max size prevents it) then it will be aligned top-left within the space unless the child's alignment constraint has been set.
    Returns:
      the value of the `left` property
    See Also:
      - `setLeft(Node)`
      - `leftProperty()`

  - ### rightProperty

    public final ObjectProperty<Node> rightProperty()
    The node placed on the right edge of this border pane. If resizable, it will be resized to its preferred width and it's height will span the height of the border pane between the top and bottom nodes. If the node cannot be resized to fill the right space (it's not resizable or its max size prevents it) then it will be aligned top-right within the space unless the child's alignment constraint has been set.
    Returns:
      the node placed on the right edge of this border pane
    See Also:
      - `getRight()`
      - `setRight(Node)`

  - ### setRight

    public final void setRight(Node value)
    Sets the value of the `right` property.
    Property description:
      The node placed on the right edge of this border pane. If resizable, it will be resized to its preferred width and it's height will span the height of the border pane between the top and bottom nodes. If the node cannot be resized to fill the right space (it's not resizable or its max size prevents it) then it will be aligned top-right within the space unless the child's alignment constraint has been set.
    Parameters:
      `value` - the value for the `right` property
    See Also:
      - `getRight()`
      - `rightProperty()`

  - ### getRight

    public final Node getRight()
    Gets the value of the `right` property.
    Property description:
      The node placed on the right edge of this border pane. If resizable, it will be resized to its preferred width and it's height will span the height of the border pane between the top and bottom nodes. If the node cannot be resized to fill the right space (it's not resizable or its max size prevents it) then it will be aligned top-right within the space unless the child's alignment constraint has been set.
    Returns:
      the value of the `right` property
    See Also:
      - `setRight(Node)`
      - `rightProperty()`

  - ### getContentBias

    public Orientation getContentBias()
    Description copied from class: `Node`
    Returns the orientation of a node's resizing bias for layout purposes. If the node type has no bias, returns null. If the node is resizable and it's height depends on its width, returns HORIZONTAL, else if its width depends on its height, returns VERTICAL.

    Resizable subclasses should override this method to return an appropriate value.

    Overrides:
      `getContentBias` in class `Node`
    Returns:
      null unless the center, right, bottom, left or top has a content bias.
