Stage/Scene Close on ESCAPE key Event in Java FX

Close Event on Pressing ESCAPE in Java FX

For this you have to apply onkeyPressed Event on ESCAPE. Sample code as follows:

import javafx.application.Application;
import javafx.event.EventHandler;
import javafx.geometry.Insets;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.PasswordField;
import javafx.scene.control.TextField;
import javafx.scene.input.KeyCode;
import javafx.scene.input.KeyEvent;
import javafx.scene.layout.GridPane;
import javafx.scene.layout.HBox;
import javafx.scene.text.Text;
import javafx.stage.Stage;

public class TableViewSample extends Application {

    public static void main(String[] args) {
    launch(args);
}

@Override
public void start(final Stage primaryStage) {
    primaryStage.setTitle("JavaFX Welcome");
    GridPane grid = new GridPane();
    grid.setAlignment(Pos.CENTER);
    grid.setHgap(10);
    grid.setVgap(10);
    grid.setPadding(new Insets(25, 25, 25, 25));

    Text scenetitle = new Text("Welcome");
    scenetitle.setId("welcome-text");
    grid.add(scenetitle, 0, 0, 2, 1);

    Label userName = new Label("User Name:");
    grid.add(userName, 0, 1);

    TextField userTextField = new TextField();
    grid.add(userTextField, 1, 1);

    Label pw = new Label("Password:");
    grid.add(pw, 0, 2);

    PasswordField pwBox = new PasswordField();
    grid.add(pwBox, 1, 2);

    Button btn = new Button("Sign in");
    HBox hbBtn = new HBox(10);
    hbBtn.setAlignment(Pos.BOTTOM_RIGHT);
    hbBtn.getChildren().add(btn);
    grid.add(hbBtn, 1, 4);

    Scene scene = new Scene(grid, 660, 300);
    scene.setOnKeyPressed(new EventHandler<KeyEvent>() {
        public void handle(KeyEvent ke) {
            if (ke.getCode() == KeyCode.ESCAPE) {
                System.out.println("Key Pressed: " + ke.getCode());
                primaryStage.close();
            }
        }
    });
    //primaryStage.setFullScreen(true);
    primaryStage.setScene(scene);
    primaryStage.show();
}
}
