jfxtras.util.NodeUtil

public class NodeUtil
extends java.lang.Object

Utility class that provides methods to simplify node handling. Possible use cases are searching for nodes at specific locations, adding/removing nodes to/from parents (Parent interface does not give write access to children).

Method Detail

screenX

public static double screenX(javafx.scene.Node node)

Parameters:

node -

Returns:

The X screen coordinate of the node.

screenY

public static double screenY(javafx.scene.Node node)

Parameters:

node -

Returns:

The Y screen coordinate of the node.

removeFromParent

public static void removeFromParent(javafx.scene.Node n)

Removes the specified node from its parent.

Parameters:

n - the node to remove

Throws:

java.lang.IllegalArgumentException - if an unsupported parent class has been specified or the parent is <code>null</code>

addToParent

public static void addToParent(javafx.scene.Parent p,
                               javafx.scene.Node n)

Adds the given node to the specified parent.

Parameters:

p - parent

n - node

Throws:

java.lang.IllegalArgumentException - if an unsupported parent class has been specified or the parent is <code>null</code>

getNode

public static javafx.scene.Node getNode(javafx.scene.Parent p,
                                        double sceneX,
                                        double sceneY,
                                        java.lang.Class<?> nodeClass)

Returns the first node at the given location that is an instance of the specified class object. The search is performed recursively until either a node has been found or a leaf node is reached.

Parameters:

p - parent node

sceneX - x coordinate

sceneY - y coordinate

nodeClass - node class to search for

Returns:

a node that contains the specified screen coordinates and is an instance of the specified class or null if no such node exist
