JavaFX open new window - javafx-2

Question

Looking at this code they show a way to display a new window after a login. When username and password are correct it opens new dialog. I want a button click to open new dialog, without checking for username and password.

Answer 1

If you just want a button to open up a new window, then something like this works:
btnOpenNewWindow.setOnAction(new EventHandler<ActionEvent>() {
public void handle(ActionEvent event) {
Parent root;
try {
root = FXMLLoader.load(getClass().getClassLoader().getResource("path/to/other/view.fxml"), resources);
Stage stage = new Stage();
stage.setTitle("My New Stage Title");
stage.setScene(new Scene(root, 450, 450));
stage.show();
// Hide this current window (if this is what you want)
((Node)(event.getSource())).getScene().getWindow().hide();
}
catch (IOException e) {
e.printStackTrace();
}
}
}

I use the following method in my JavaFX applications.
newWindowButton.setOnMouseClicked((event) -> {
try {
FXMLLoader fxmlLoader = new FXMLLoader();
fxmlLoader.setLocation(getClass().getResource("NewWindow.fxml"));
/*
* if "fx:controller" is not set in fxml
* fxmlLoader.setController(NewWindowController);
*/
Scene scene = new Scene(fxmlLoader.load(), 600, 400);
Stage stage = new Stage();
stage.setTitle("New Window");
stage.setScene(scene);
stage.show();
} catch (IOException e) {
Logger logger = Logger.getLogger(getClass().getName());
logger.log(Level.SEVERE, "Failed to create new Window.", e);
}
});

The code below worked for me I used part of the code above inside the button class.
public Button signupB;
public void handleButtonClick (){
try {
FXMLLoader fxmlLoader = new FXMLLoader();
fxmlLoader.setLocation(getClass().getResource("sceneNotAvailable.fxml"));
/*
* if "fx:controller" is not set in fxml
* fxmlLoader.setController(NewWindowController);
*/
Scene scene = new Scene(fxmlLoader.load(), 630, 400);
Stage stage = new Stage();
stage.setTitle("New Window");
stage.setScene(scene);
stage.show();
} catch (IOException e) {
Logger logger = Logger.getLogger(getClass().getName());
logger.log(Level.SEVERE, "Failed to create new Window.", e);
}
}
}
