[FIXED] firing a click event when pressing enter inside a textfield

Issue

sorry for the questions... but I'm a little stuck again.

I ask these questions so I can get the most out of my time/learning.

I am trying to fire a click event (so when i manually click the login btn) with the enter key.

The code i have so far

code

 usernameField.setOnKeyPressed((KeyEvent event) -> {
        if(event.getCode()==KeyCode.ENTER){
            loginBtn.fire();
            System.out.println("Worked");
        }
    });

That does what it's supposed to, almost. the system out message appears but does now fire the loginBtn.

I am using JavaFX and JFXButtons/textboxes if that makes a difference

Solution

Text fields fire action events when the user presses the enter key. So all you need is

EventHandler<ActionEvent> loginHandler = e -> {
    // handle login here...
};

usernameTextField.setOnAction(loginHandler);
loginBtn.setOnAction(loginHandler);

Or, if you prefer;

usernameTextField.setOnAction(e -> handleLogin());
loginBtn.setOnAction(e -> handleLogin());

// ...

private void handleLogin() {
    // handle login here...
}

If you are using FXML, you can just map both onAction handlers to the same controller method:

<TextField fx:id="usernameTextField" onAction="#login" />
<Button fx:id="loginBtn" text="Log In" onAction="#login" />

and then in the controller

public class Controller {

    // ...

    @FXML
    private void login() {
        // login action here..
    }

    // ...

}
