JavaFX (Scene builder) arrow keys OnKeyPressed - javafx

Question

I'm in the middle of a school project, but I'm stuck...
In Scene Builder there is an OnKeyPressed and an OnKeyReleased 'method', and when I assign my own method (See code further down) I want to check if I'm pressing the left or right arrow key.
The problem is, OnKeyReleased works fine, but the OnKeyPressed only works when I hold down shift!
Does anyone know the cause of this issue? and if so, how it can be fixed/worked around?
(I'm on a MacBook, could this have anything to do with it?)
Thanks :)
Method for OnKeyPressed:
#FXML
private void Input(KeyEvent e)
{
if(e.getCode().equals(KeyCode.LEFT))
{
System.out.println("Pressed left arrow key");
}
}
FullCode:
package seasweeper.seasweeper;
import java.io.IOException;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Label;
import javafx.scene.input.KeyCode;
import javafx.scene.input.KeyEvent;
public class SecondaryController implements Initializable {
#FXML
private Label Label_Character;
/**
* Initializes the controller class.
*/
#Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
}
#FXML
private void switchToPrimary() throws IOException
{
App.setRoot("primary");
}
#FXML
private void Input(KeyEvent e)
{
if(e.getCode().equals(KeyCode.LEFT))
{
System.out.println("Pressed left");
}
System.out.println("KeyCode: " + e.getCode());
}
}

Answer 1

On the same issue I changed OnKeyPressed from AnchorPane to some Button on that AnchorPane and OnKeyPressed works fine with arrows :)
#Override
public void initialize(URL location, ResourceBundle resources) {
someButton.addEventHandler(KeyEvent.KEY_PRESSED,
new EventHandler<KeyEvent>() {
#Override
public void handle(KeyEvent event) {
switch (event.getCode().toString()) {
// your logic here
}
event.consume();
}
});
}

Answer 2

This one is a little tricky, but still relatively simple:
Node node = null;
node.setOnKeyPressed(new EventHandler<KeyEvent>() {
#Override
public void handle(KeyEvent event) {
if (event.getCode() == KeyCode.KP_UP) { // KeyPressed_UP
// Do something
}
if (event.getCode() == KeyCode.KP_DOWN) { // KeyPressed_DOWN
// Do something
}
if (event.getCode() == KeyCode.KP_LEFT) { // KeyPressed_LEFT
// Do something
}
if (event.getCode() == KeyCode.KP_RIGHT) { // KeyPressed_RIGHT
// Do something
}
}
});
Remember to change "node" with your object (it could be a Scene, AnchorPane -or any kind of pane-, buttons, etc).
