i want to do like Cancel or close button operation
written the statement
x.show();
in another class
and want to close x means

I use a JavaFX Popup in my application to change the Shipping Address of a customer. That often requires copy pasting the Address from the web browser. If I click on the Popup after the application lost focus it will not regain focus. I first need to click the parent window behind the popup and then click the Popup again to be able to interact with it.
Is there any way to solve that problem, besides using an undecorated stage instead of a Popup?
EDIT:
Here I made a minimal example:
public class HelloApplication extends Application {
#Override
public void start(Stage stage) throws IOException {
Scene scene = new Scene(new VBox(), 600, 600);
stage.setTitle("Hello!");
stage.setScene(scene);
stage.show();
Popup popup = new Popup();
Button btn = new Button("This is a very nice button!");
btn.setOnAction(actionEvent -> System.out.println("button clicked"));
TextField textField = new TextField();
textField.setOnMouseClicked(mouseEvent -> System.out.println("textField clicked"));
VBox popupVBox = new VBox(btn, textField);
popupVBox.setStyle("-fx-background-color: white");
popupVBox.setPadding(new Insets(10));
popup.getContent().add(popupVBox);
popup.show(scene.getWindow());
}
public static void main(String[] args) {
launch();
}
}
If you click outside of the application (for example the web browser, to copy some value) then you can not enter Text into the TextField anymore. The button action listener and even the TextField mouse Listener still work and output "button clicked" and "textField clicked" but the blue halo around them does not apppear and you can not enter (or paste) text into the TextField. After you click somewhere on the main Stage of the application it works again.
I tried adding textField.requestFocus();
to the mouse Listener of the textfield but that does not do anything.
EDIT 2 after the comment from kleopatra:
I tried adding the following code:
popupVBox.setOnMouseEntered(mouseEvent -> {
popup.getOwnerWindow().requestFocus();
parentVBox.toFront(); //This is created above and passed to the new Scene instead of diectly passing new VBox() as in the code snippet posted above
});
With that code added, popup and its children seem to have focus if the mouse is hoverd over it after an other application had focus, i.e. if clicked with the mouse the blue border appears around the button and textField, and if there is any text in the textField I can move the cursor with the mouse and select the text with the mouse, buy any keyboard inputs are ignored. Actually they are executed in the other application which had focus before. If I ctrl+c in Intellij and try to ctrl+v into the textfield it will be pasted to the Intellij editor. Also the arrow keys move the cursor in the intellij window instead of the textField.
The only way to be able to type anything in the TextField is to click the parent window first.
Also
textField.setOnMouseClicked(mouseEvent -> {
textField.requestFocus();
});
does not do anything
not an answer, just to clarify the comment (will delete if seen by OP :)
public class PopupFocus extends Application {
#Override
public void start(Stage stage) throws IOException {
Scene scene = new Scene(new VBox(), 300, 300);
stage.setTitle("Hello!");
stage.setScene(scene);
stage.setX(10);
stage.show();
Popup popup = new Popup();
Button btn = new Button("This is a very nice button!");
btn.setOnAction(actionEvent -> System.out.println("button clicked"));
TextField textField = new TextField();
textField.setOnMouseClicked(mouseEvent -> {
System.out.println("textField clicked");
stage.toFront();
});
VBox popupVBox = new VBox(btn, textField);
popupVBox.setStyle("-fx-background-color: white");
popupVBox.setPadding(new Insets(10));
popup.getContent().add(popupVBox);
// original
popup.show(scene.getWindow());
}
public static void main(String[] args) {
launch();
}
}
My controller class has a moveButton method that on button click moves the button to a new location. This works fine and is called by a number of buttons which do the same thing. I want to add a key listener so when a button has been clicked once, until a different button is clicked, the user can use the up arrow to move the button (ie call the same moveButton function). The below is how I have tried to implement it, I also tried putting the key listener in the initialize method but neither seem to be working. Any advice would be greatly appreciated!
public void moveButton(ActionEvent actionEvent) {
Button buttonPressed = (Button) actionEvent.getSource();
double newAnchor = getNewAnchor(AnchorPane.getBottomAnchor(buttonPressed)) // separate method that returns new anchor location
AnchorPane.setBottomAnchor(buttonPressed, newAnchor);
buttonPressed.getScene().setOnKeyPressed(new EventHandler<KeyEvent>() {
#Override
public void handle(KeyEvent event) {
if(event.getCode() == KeyCode.UP){
moveButton(actionEvent);
}
}
});
}
Don't treat the events like data that you need to pass around. Use them as triggers to do work. Generally, don't write generic event handlers that are called from multiple events and multiple nodes. Write short event handlers that just call methods to do something, and pass them the minimum from the event that they need to do the job.
If you do this, then it changes your thinking about how all of this stuff works and then it's just plain old Java, with no magic. And it's simple:
public class MoveButton extends Application {
private Node activeButton;
private Pane pane;
#Override
public void start(Stage primaryStage) throws Exception {
pane = new Pane();
Scene scene = new Scene(pane, 1200, 800);
primaryStage.setScene(scene);
primaryStage.show();
Button button1 = new Button("Button 1");
Button button2 = new Button("Button 2");
button2.setTranslateX(80);
button1.setOnAction(evt -> buttonClick(button1));
button2.setOnAction(evt -> buttonClick(button2));
pane.getChildren().addAll(button1, button2);
pane.setOnKeyPressed(evt -> moveButton(evt.getCode()));
}
private void moveButton(KeyCode keyCode) {
switch (keyCode) {
case UP -> activeButton.setTranslateY(activeButton.getTranslateY() - 30);
case RIGHT -> activeButton.setTranslateX(activeButton.getTranslateX() + 30);
case DOWN -> activeButton.setTranslateY(activeButton.getTranslateY() + 30);
case LEFT -> activeButton.setTranslateX(activeButton.getTranslateX() - 30);
}
}
private void buttonClick(Node button) {
activeButton = button;
pane.requestFocus();
}
}
I'm new to JavaFX. Unlike Swing, JavaFX's combo box's action event seems to be fired when the selection actually changed. In Swing, you can add an ActionListener on a JComboBox and it will fire an event whenever you make a selction (by clicking on one of the choices in the combo box), regardless of if the selected value actually changed. Can we achieve the same behavior in JavaFX? Some code below. What I want is to select "Hello" and have it printed, and select "Hello" again and have it printed again.
public class ComboBoxSelection extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) throws Exception {
VBox layout = new VBox();
ComboBox<String> comboBox = new ComboBox<>();
comboBox.getItems().addAll("Hello", "World");
comboBox.setOnAction(event -> System.out.println("Selected " + comboBox.getValue()));
layout.getChildren().addAll(comboBox);
Scene scene = new Scene(layout);
primaryStage.setScene(scene);
primaryStage.show();
}
}
I noticed a thread here: ComboBox SAME item selected action listener. This almost gives me what I want, except this fires when the selection cancels (press Esc) as well. Is there any other solution? Thanks in advance.
Firstly, sorry for my English. I hope, you unterstand it.
Last Month I started developing a little programm with FXML/ JavaFX.
I have two screens, and I'm switching between them. This is not the problem.
The problem is: On one Screen i have a listview, where i can choose an item. When i have chosen an item, i want to open a new tab on the other screen with the content of the item. Therefore, i have to click on a button.
When i have chosen an item, i can print out the selected item, but how do I open a new tab on the other screen. Both Screens a two different FXML and are activited from the controller. How can I add a Tab, although loading fxml?
public class Controller{
#FXML
private ListView<String> lv;
#FXML
private Button check;
#FXML
public void projectview (Event e3) throws Exception{
Stage stage = null;
Parent root = null;
if(e3.getSource()==check){
//Check is the declaration for the Button on the screen with the listview
String projectview= lv.getSelectionModel().getSelectedItem();
stage = (Stage) check.getScene().getWindow();
root = FXMLLoader.load(getClass().getResource("FXML1.fxml"));
//Here I want to add a tab in FXML1.fxml
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
}
}
If something is missing or not clear, please ask. I read other similar questions, but i don't know, what to do.
Thanks for help
I have a controller that opens a new stage as a popup:
#FXML
private void onClickPayments(ActionEvent event) throws IOException{
FXMLLoader loader = new FXMLLoader(getClass().getResource("ClientPayments.fxml"));
Parent root = (Parent) loader.load();
ClientPaymentsController controller = (ClientPaymentsController) loader.getController();
Scene scene = new Scene(root);
Stage stage = new Stage();
stage.setScene(scene);
stage.initModality(Modality.APPLICATION_MODAL);
stage.setResizable(false);
stage.setOnCloseRequest((WindowEvent we) -> {
clientBLL.retrieve(clientID);
updateWarning();
});
stage.show();
controller.setClientID(clientID);
}
When the other stage is closed by the 'x' button the 'stage.setOnCloseRequest' is executed. But in that stage I have a button to close:
#FXML
private void onClickExit(ActionEvent event){
((Stage) ((Node) event.getSource()).getScene().getWindow()).close();
}
It closes, but the method 'stage.setOnCloseRequest' isn't being executed.
Is this method wrong or is there a way to close a popup in a way that acts exactly like the 'x' button in the window?
The setOnCloseRequest handler is executed when there is an external request to close the window (i.e. not one from your code). See the documentation.
If it's enough to execute that logic immediately after the window is closed, just use the regular onHidden handler instead:
stage.setOnHidden((WindowEvent we) -> {
clientBLL.retrieve(clientID);
updateWarning();
});
If you really need to use the onCloseRequest handler (e.g. because you might want to veto the close), just move your close logic to a method and invoke it from both types of request to close the window.
public void doClose() {
clientBLL.retrieve(clientID);
updateWarning();
}
#FXML
private void onClickExit(ActionEvent event){
doClose();
((Node) event.getSource()).getScene().getWindow().hide();
}
and
stage.setOnCloseRequest((WindowEvent we) -> {
controller.doClose();
});
