org.fxmisc.wellbehaved.event.Nodes

public class Nodes
extends java.lang.Object

Helper class for "installing/uninstalling" an InputMap into a Node.

Method Summary

• To add an InputMap as a default behavior that can be overridden later, use addFallbackInputMap(Node, InputMap).
• To add an InputMap that might override default behaviors, use addInputMap(Node, InputMap).
• To remove an InputMap, use removeInputMap(Node, InputMap).
• See also pushInputMap(Node, InputMap) and popInputMap(Node) for temporary behavior modification.

Method Summary

Modifier and Type	Method and Description
static void	addFallbackInputMap(javafx.scene.Node node, InputMap<?> im) Adds the given input map to the end of the node's list of input maps, so that an event will be pattern-matched against all other input maps currently "installed" in the node before being pattern-matched against the given input map.
static void	addInputMap(javafx.scene.Node node, InputMap<?> im) Adds the given input map to the start of the node's list of input maps, so that an event will be pattern-matched against the given input map before being pattern-matched against any other input maps currently "installed" in the node.
static InputMap<?>	getInputMap(javafx.scene.Node node) Gets the InputMap for the given node or InputMap.empty() if there is none.
static boolean	popInputMap(javafx.scene.Node node) If the internal stack has an InputMap, removes the current InputMap that was installed on the give node via pushInputMap(Node, InputMap), reinstalls the previous InputMap, and then returns true.
static void	pushInputMap(javafx.scene.Node node, InputMap<?> im) Removes the currently installed InputMap (InputMap1) on the given node and installs the im (InputMap2) in its place.
static void	removeInputMap(javafx.scene.Node node, InputMap<?> im) Removes (or uninstalls) the given input map from the node.

Method Detail

addInputMap

public static void addInputMap(javafx.scene.Node node,
                               InputMap<?> im)

Adds the given input map to the start of the node's list of input maps, so that an event will be pattern-matched against the given input map before being pattern-matched against any other input maps currently "installed" in the node.

addFallbackInputMap

public static void addFallbackInputMap(javafx.scene.Node node,
                                       InputMap<?> im)

Adds the given input map to the end of the node's list of input maps, so that an event will be pattern-matched against all other input maps currently "installed" in the node before being pattern-matched against the given input map.

removeInputMap

public static void removeInputMap(javafx.scene.Node node,
                                  InputMap<?> im)

Removes (or uninstalls) the given input map from the node.

getInputMap

public static InputMap<?> getInputMap(javafx.scene.Node node)

Gets the InputMap for the given node or InputMap.empty() if there is none.

pushInputMap

public static void pushInputMap(javafx.scene.Node node,
                                InputMap<?> im)

Removes the currently installed InputMap (InputMap1) on the given node and installs the im (InputMap2) in its place. When finished, InputMap2 can be uninstalled and InputMap1 reinstalled via popInputMap(Node). Multiple InputMaps can be installed so that InputMap(n) will be installed over InputMap(n-1)

popInputMap

public static boolean popInputMap(javafx.scene.Node node)

If the internal stack has an InputMap, removes the current InputMap that was installed on the give node via pushInputMap(Node, InputMap), reinstalls the previous InputMap, and then returns true. If the stack is empty, returns false.
