public class AnchorPane extends Pane
AnchorPane lays out each managed child regardless of the child's visible property value; unmanaged children are ignored for all layout calculations.
AnchorPanes may be styled with backgrounds and borders using CSS. See
Region superclass for details.
| Constraint | Type | Description |
|---|---|---|
| topAnchor | double | distance from the anchor pane's top insets to the child's top edge. |
| leftAnchor | double | distance from the anchor pane's left insets to the child's left edge. |
| bottomAnchor | double | distance from the anchor pane's bottom insets to the child's bottom edge. |
| rightAnchor | double | distance from the anchor pane's right insets to the child's right edge. |
AnchorPane Example:
AnchorPane anchorPane = new AnchorPane();
// List should stretch as anchorPane is resized
ListView list = new ListView();
AnchorPane.setTopAnchor(list, 10.0);
AnchorPane.setLeftAnchor(list, 10.0);
AnchorPane.setRightAnchor(list, 65.0);
// Button will float on right edge
Button button = new Button("Add");
AnchorPane.setTopAnchor(button, 10.0);
AnchorPane.setRightAnchor(button, 10.0);
anchorPane.getChildren().addAll(list, button);
| width | height | |
|---|---|---|
| minimum | left/right insets plus width required to display children anchored at left/right with at least their min widths | top/bottom insets plus height required to display children anchored at top/bottom with at least their min heights |
| preferred | left/right insets plus width required to display children anchored at left/right with at least their pref widths | top/bottom insets plus height required to display children anchored at top/bottom with at least their pref heights |
| maximum | Double.MAX_VALUE | Double.MAX_VALUE |
An anchor 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.
AnchorPane 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:
anchorPane.setPrefSize(300, 300);
AnchorPane does not clip its content by default, so it is possible that childrens' bounds may extend outside its own bounds if the anchor pane is resized smaller than its preferred size.

Returns the child's top anchor constraint if set.
|
protected void |
layoutChildren()
Invoked during the layout pass to layout the children in this
Parent. |
static void |

Double value)
Sets the bottom anchor for the child when contained by an anchor pane.
|
static void |
setLeftAnchor(Node child,
Double value)
Sets the left anchor for the child when contained by an anchor pane.
|
static void |
setRightAnchor(Node child,
Double value)

ParentParent. By default it will only set the size of managed,
resizable content to their preferred sizes and does not do any node
positioning.
Subclasses should override this function to layout content as needed.
