I have tic-tac-toe game on BorderPane. On the left side I have simple chat. I want set possibility send another message after first after 5 second, i.e. I want set disable for chat for 5 second, but another parts of application must work. How can I do this.
#FXML
private GridPane mainGridPane; //here game
#FXML
private GridPane smileGridPane; //this I want stop for five second
A PauseTransition with a onFinished handler reenabling the pane will do the trick:
smileGridPane.setDisable(true); // disable target pane
PauseTransition pause = new PauseTransition(Duration.seconds(5));
pause.setOnFinished(evt -> smileGridPane.setDisable(false)); // reenable target pane
pause.play();

I'm trying to build a message window with App Bar on the top
This screen consist of Gluon App Bar on the top and VBox in bottom which has rest of the element shown in the screen.
Issue is when i click on the text area to enter text the App Bar goes out of scope.
Is there a way I can set App Bar to be always on top?
If you are deploying your app on Android, the TextField and TextArea controls include a built-in check: when those input controls get focused, if required the scene is moved up to prevent the software keyboard from hiding the control.
These translation affects the whole scene, so all the nodes in it (View, VBox, TextField, TextArea, AppBar, ...), will be translated as well.
So if you want to keep the AppBar node always visible and in the same top position, a possible fix could be counteracting that translation whenever it happens.
If you have a BasicView for instance (Gluon IDE plugin -> single view project), with a TextField control at the bottom of the view:
public BasicView() {
Label label = new Label("Hello JavaFX World!");
Button button = new Button("Change the World!");
button.setGraphic(new Icon(MaterialDesignIcon.LANGUAGE));
button.setOnAction(e -> label.setText("Hello JavaFX Universe!"));
VBox controls = new VBox(15.0, label, button, new TextField());
controls.setAlignment(Pos.BOTTOM_CENTER);
controls.setPadding(new Insets(20));
setCenter(controls);
}
you can modify it like this:
public BasicView() {
...
setOnShown(e -> {
MobileApplication.getInstance().getAppBar().translateYProperty()
.bind(controls.getScene().getRoot().translateYProperty().multiply(-1));
});
}
Make sure that the view is already added to the scene when you add this binding (to prevent a NPE).
Now when the textfield gets the focus, the whole scene will be moved up, and the appBar will be moved down the same amount:
Essentially, what I'm trying to do is something like to a text-based RPG using JavaFX. Right now, to display some text, I've got this:
final IntegerProperty i = new SimpleIntegerProperty(0);
Timeline timeline = new Timeline();
KeyFrame keyFrame = new KeyFrame(
Duration.millis(70),
event -> {
if (i.get() > info.getText().length()) {
timeline.stop();
} else {
text.setText(info.getText().substring(0, i.get()));
i.set(i.get() + 1);
}
});
timeline.getKeyFrames().add(keyFrame);
timeline.setCycleCount(Animation.INDEFINITE);
timeline.play();
timeline.setOnFinished(a -> {
hb_start.getChildren().clear();
hb_start.getChildren().addAll(start_left,start_right);
hb_start.setAlignment(Pos.CENTER);
});
Because the length of the animation depends on the size of the text, the cyclecount is set to indefinite. Unless there's some other way I'm missing to make the animation play once and then stop, I'd like it so that when you press enter (or some other key that I decide on later) for it to call timeline.stop(); but I can't figure out how to add any sort of listener. Trying to implement keyListenerseems to come with all sorts of stuff that I don't need, and it also doesn't work with a TextField, and instead wants a JTextField, which might be fine, except that I don't have a clue how to do anything with Swing.
Currently, the text is being displayed in aTextFlow from the text of Text. I'm assuming the listener would be added to the TextFlow, or even the scene itself, honestly, I'm at a loss for what to do. It sounds simple, but I can't seem to figure it out.
KeyListener is a AWT class, not a JavaFX class. Unless you're embedding a Swing component in your JavaFX application or a JavaFX node in a Swing application, you should use JavaFX's equivalent EventHandler<KeyEvent> instead. Furthermore there is no need to include a TextField (or Swing's JTextField) in your application just for the sake of receiving key events. You could add the listener directly to the Scene:
final KeyCode stopKey = KeyCode.ENTER;
EventHandler<KeyEvent> handler = event -> {
if (event.getCode() == stopKey) {
timeline.stop();
}
};
scene.setOnKeyPressed(handler);
Note that events can be consumed by nodes before they reach the scene, e.g. by a TextField that has the focus. In this case you could make sure you get the event by registering a the listener as a event filter instead:
// scene.setOnKeyPressed(handler);
scene.addEventFilter(KeyEvent.KEY_PRESSED, handler);
I'm running into a bit of a problem. I'm creating a program for a client. In the program, I have implement a dedicated 'close/shut down' button - which requires a password in order to properly shut down. But an alternative (and less safe) way of closing the program is by hitting the red close or 'X' button: top right (Windows) or top left(Mac).
I do not want the red x button to actually close the entire program. What I would like to know: is it possible to completely disable the red 'x' button from closing the entire program? If possible, could someone provide code for this?
What I'm using: IntelliJ IDEA (Ultimate), JavaFX with Java 8, Dev. Language: Java
Add a event handler to the onCloseRequest event of the stage. This allows you to prevent the window from closing by consuming the event and executing your own shutdown procedure instead:
private void shutdown(Stage mainWindow) {
// you could also use your logout window / whatever here instead
Alert alert = new Alert(Alert.AlertType.NONE, "Really close the stage?", ButtonType.YES, ButtonType.NO);
if (alert.showAndWait().orElse(ButtonType.NO) == ButtonType.YES) {
// you may need to close other windows or replace this with Platform.exit();
mainWindow.close();
}
}
#Override
public void start(Stage primaryStage) {
primaryStage.setOnCloseRequest(evt -> {
// prevent window from closing
evt.consume();
// execute own shutdown procedure
shutdown(primaryStage);
});
StackPane root = new StackPane();
Scene scene = new Scene(root, 100, 100);
primaryStage.setScene(scene);
primaryStage.show();
}
Is there any way I can have an event that only triggers if I click the Title of a TitledPane?
I have several Nodes in a Graph Editor and currently they are draggable.
But I want them only to drag when i drag the Title not if I click anywhere on the pane.
the mouseClick event seems not to work for me.
Does anyone have suggestions?
Don't set the text on the titled pane, but instead create a label and set it as the graphic for the titled pane. Then you can register a mouse handler with the label:
private TitledPane createClickableTitledPane(String text) {
Label label = new Label(text);
label.setOnMouseClicked(e -> System.out.println("Click on "+text));
TitledPane titledPane = new TitledPane();
titledPane.setGraphic(label);
return titledPane ;
}
StackPane titleRegion = (StackPane) titledPane.lookup(".title");
titleRegion.setOnMouseClicked(System.out::println);
EDIT:
Sometimes titledPane.lookup(".title") returns null which means CSS is not applied to the node. To resolve this issue, you need to use applyCss() and layout() on the pane that contains the TitledPane.
See:
JavaFX TitledPane lookup(.title) returns null
I want to make a button on an AnchorPane without drag it from the library in the FXML file I want to do it progammatically: if the search button clicked, should show a new button not existed in the AnchorPane before I did this code but I don't know what is wrong with it:
private void searchButton(ActionEvent evt) {
Button tab = new Button();
tab.setLayoutX(147);
tab.setLayoutY(102);
tab.setText("Tab1");
tab.setPrefHeight(27);
tab.setPrefWidth(69);
WebView wb = new WebView();
wb.setLayoutX(-1);
wb.setLayoutY(128);
wb.setPrefWidth(1604);
wb.setPrefWidth(700);
}
I am assuming that you searchButton method is in controller attached to some FXML. Then all you need to do is this:
yourAnchorPane.getChildren().add(tab);
If you don't have already published reference to anchorPane in your controller, then add this into your controller
#FXML
AnchorPane yourAnchorPane;
And in SceneBuilder select your anchorPane, go to code tab and enter "yourAnchorPane" as fx:id.
Further info on working with anchorpane is javadoc.
You probably also want to set some constraints on the tab to locate it at a position within the AnchorPane. For instance, the following code will locate your button tab relative to the top left corner of the AnchorPane: Ten pixels down and fifteen pixels to the right.
AnchorPane.setTopAnchor(tab, 10.0);
AnchorPane.setLeftAnchor(tab, 15.0);
