I have a small test a JButton in a SwingNode in a Stage, using Java 8.
Problem: right click is not triggered, the middle click is interpreted as right click ...
Here is the code:
Platform.runLater(new Runnable() {
#Override
public void run() {
HBox hb = new HBox();
SwingNode n = new SwingNode();
JButton b = new JButton("CLICK ME!!!");
b.addMouseListener(new MouseAdapter() {
public final void mousePressed(MouseEvent e) {
boolean isLeftClick = SwingUtilities.isLeftMouseButton(e);
boolean isRightClick = SwingUtilities.isRightMouseButton(e);
if (isLeftClick)
System.out.println("Left");
if (isRightClick)
System.out.println("Right");
}
});
n.setContent(b);
hb.getChildren().add(n);
Stage stage = new Stage();
Scene appScene = new Scene(hb,100, 100);
stage.setScene(appScene);
stage.show();
}
});

I've so far done this, it's adding labels on the stage but removing thing is working but not as intended...
How can I store data of labels in an array or something so I can compare the remove.getText(); with that and delete that typed value if previous added as a label on stage.
public class Main extends Application {
Group root;
Label label1,label;
int count=1,count1=1;
public static void main(String[] args) {launch(args);}
public void start(Stage stage) throws Exception {
stage.setTitle("LinkedList GUI");
stage.setResizable(false);
root = new Group();
LinkedList<Integer> Linked =new LinkedList<Integer>();
Button Addfirst = new Button("AddFirst");
Addfirst.setTranslateX(40);
Addfirst.setTranslateY(350);
TextField first=new TextField();
first.setPrefWidth(60);
first.setTranslateX(120);
first.setTranslateY(350);
Addfirst.setOnAction(new EventHandler<ActionEvent>() {
#Override public void handle(ActionEvent e) {
int a = Integer.parseInt(first.getText());
Linked.addFirst(a);
label1=new Label(" "+first.getText());
label1.setFont(Font.font("Buxton Sketch",FontWeight.BOLD,FontPosture.ITALIC,12));
label1.setPrefWidth(25);
label1.setPrefHeight(25);
label1.setTranslateY(60);
label1.setTextFill(Color.GREEN );
label1.setStyle("-fx-border-color: Blue;");
root.getChildren().addAll(label1);
label1.setTranslateX(250-(20*count++));
count++;
}
});
Button Addlast = new Button("AddLast");
Addlast.setTranslateX(200);
Addlast.setTranslateY(350);
TextField last=new TextField();
last.setPrefWidth(60);
last.setTranslateX(270);
last.setTranslateY(350);
Addlast.setOnAction(new EventHandler<ActionEvent>() {
#Override public void handle(ActionEvent e) {
int b= Integer.parseInt(last.getText());
Linked.addLast(b);
label=new Label(" "+last.getText());
label.setFont(Font.font("Buxton Sketch",FontWeight.BOLD,FontPosture.ITALIC,12));
label.setPrefWidth(25);
label.setPrefHeight(25);
label.setTranslateY(60);
label.setTextFill(Color.GREEN );
label.setStyle("-fx-border-color: Blue;");
root.getChildren().add(label);
label.setTranslateX(250+(20*count1++));
count1++;
}
});
Button delete = new Button("Delete");
delete.setTranslateX(350);
delete.setTranslateY(350);
TextField remove=new TextField();
remove.setPrefWidth(60);
remove.setTranslateX(420);
remove.setTranslateY(350);
delete.setOnAction(new EventHandler<ActionEvent>() {
#Override public void handle(ActionEvent e) {
if(remove.getText().equals(first.getText())) {
Linked.remove(first.getText());
root.getChildren().remove(label1);
}
else if(remove.getText().equals(last.getText())) {
Linked.remove(last.getText());
root.getChildren().remove(label);
}
else {
Alert alert = new Alert(AlertType.ERROR);
alert.setTitle("Error");
alert.setContentText("Not in List");
alert.showAndWait();
}
}
});
Text text =new Text("Doubly LinkedList GUI");
text.setStyle("-fx-border-color: Blak;");
text.setFont(Font.font("Buxton Sketch",FontWeight.BOLD,FontPosture.ITALIC,16));
text.setTranslateX(150);
text.setTranslateY(30);
root.getChildren().addAll(text,Addfirst,first,Addlast,last,delete,remove);
Scene scene = new Scene(root,500,400);
stage.setScene(scene);
stage.show();
}
}
I recommend using a layout that positions the children for you instead of positioning them yourself. E.g. using a HBox as parent for the labels allows you to simply add/remove the child at the same index as the one added/removed in the list:
#Override
public void start(Stage stage) throws Exception {
HBox container = new HBox(20);
container.setPrefHeight(40);
Button addFirst = new Button("add head");
Button addLast = new Button("add tail");
Button remove = new Button("remove");
TextField textField = new TextField();
HBox buttonContainer = new HBox(10, textField, addFirst, addLast, remove);
final LinkedList<Integer> list = new LinkedList<>();
addFirst.setOnAction(evt -> {
String text = textField.getText();
Integer value = Integer.parseInt(text);
list.addFirst(value);
container.getChildren().add(0, new Label(text));
});
addLast.setOnAction(evt -> {
String text = textField.getText();
Integer value = Integer.parseInt(text);
list.addLast(value);
container.getChildren().add(new Label(text));
});
remove.setOnAction(evt -> {
String text = textField.getText();
int value = Integer.parseInt(text);
ListIterator<Integer> iterator = list.listIterator();
while (iterator.hasNext()) {
Integer element = iterator.next();
if (element == value) {
container.getChildren().remove(iterator.nextIndex() - 1);
iterator.remove();
break;
}
}
});
VBox root = new VBox(container, buttonContainer);
Scene scene = new Scene(root, 500, 400);
stage.setScene(scene);
stage.show();
}
I want get data from Tab in Tabpane JavaFX
I have 2 Tab in Tabpane, And each Tab I have a TextArea, I want click Button will get data from 2 tab
Here's my code:
btnThem.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
try {
i++;
FXMLLoader fxmlLoader = new FXMLLoader(
getClass().getResource("/fxml/tab.fxml"));
Parent parent = (Parent) fxmlLoader.load();
Tab tab = new Tab("Điểm " + i);
tab.setContent(parent);
tab.setClosable(true);
tabPane.getTabs().add(tab);
controllerTab = (ControllerTab) fxmlLoader.getController();
} catch (IOException ex) {
Exceptions.printStackTrace(ex);
}
}
});
Your question is ambiguous but it seems you want to get data from each textArea in tab.To do this you should get nodes (children) from each tab and by using lookup() we confirm and we parse node to textArea.I tried to figure your scene and made this example to help you :
public class example extends Application {
TextArea textArea = new TextArea();
TextArea textArea1 = new TextArea();
Button button = new Button("button");
#Override
public void start(Stage primaryStage) {
Tab tab1 = new Tab("tab1");
Tab tab2 = new Tab("tab2");
tab1.setContent(textArea);
tab2.setContent(textArea1);
TabPane pane = new TabPane();
pane.getTabs().addAll(tab1, tab2);
Node node1 = tab1.getContent();
Node node2 = tab2.getContent();
button.setOnAction((ActionEvent event) -> {
if (node1.lookup("TextArea") != null && node2.lookup("TextArea") != null) {
TextArea area1 = (TextArea) node1.lookup("TextArea");
TextArea area2 = (TextArea) node2.lookup("TextArea");
System.out.println(area1.getText() + " " + area2.getText());
}
});
VBox root = new VBox();
root.setAlignment(Pos.TOP_RIGHT);
root.getChildren().add(pane);
root.getChildren().add(button);
Scene scene = new Scene(root, 300, 250);
primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();
}
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
}
And you can see the result :
Hello ,tab1 Hello ,tab2

I m trying to add a fade transition to my login and logout ImageViews, I tried to use the same pattern as the JFeonix Hamburger, I also used some tutorial at oracle docs but, there is no fade transition my ImageViews are hiding and showing instantly. What I'm missing ?
below is my code :
#FXML
private JFXHamburger menu;
#FXML
private ImageView login;
#FXML
private ImageView logout;
private LoginLogic logic;
#Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
final HamburgerSlideCloseTransition slideCloseTransition = new HamburgerSlideCloseTransition(menu);
slideCloseTransition.setRate(-1);
FadeTransition t = new FadeTransition(new Duration(3000), login);
FadeTransition t1 = new FadeTransition(new Duration(3000), logout);
t.setCycleCount(1);
t1.setCycleCount(1);
t.setAutoReverse(false);
t1.setAutoReverse(false);
t.setRate(-1);
t1.setRate(-1);
menu.addEventHandler(MouseEvent.MOUSE_PRESSED, (MouseEvent event) -> {
t1.setRate(t1.getRate() * -1);
t.setRate(t.getRate() * -1);
slideCloseTransition.setRate(slideCloseTransition.getRate() * -1);
slideCloseTransition.play();
t.play();
t1.play();
login.setVisible(!login.isVisible());
logout.setVisible(!logout.isVisible());
});
}
Thanks.
You're not changing the look of the node with the FadeTransition, since you're still using the default values for fromValue, toValue and byValue.
This means effectively you simply toggle the visibility on and off...
Usually only the opacity is modified by a FadeTransition.
Example:
#Override
public void start(Stage primaryStage) {
Button btn = new Button("fade in/out");
ImageView image = new ImageView("https://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-logo.png");
image.setOpacity(0);
VBox root = new VBox(10, btn, image);
root.setPadding(new Insets(10));
FadeTransition t = new FadeTransition(Duration.seconds(3), image);
t.setCycleCount(1);
t.setAutoReverse(false);
t.setRate(-1);
t.setFromValue(0);
t.setToValue(1);
btn.setOnAction(evt -> {
t.setRate(t.getRate() * -1);
t.play();
});
Scene scene = new Scene(root);
primaryStage.setScene(scene);
primaryStage.show();
}
I have this piece of code which doesn't work correctly.
I want to set a listener for when a user clicks inside the square, yet
neither the pop-up nor the message "clicked" are displayed when I click
inside the square.
What am I missing?
This method is inside the Coords class.
public static void drawMyShape(final GraphicsContext ctx) {
Path path = new Path();
MoveTo mT = new MoveTo();
LineTo lT[] = new LineTo[4];
mT.setX(200.0);
mT.setY(200.0);
lT[0] = new LineTo(400.0, 200.0);
lT[1] = new LineTo(400.0, 400.0);
lT[2] = new LineTo(200.0, 400.0);
lT[3] = new LineTo(200.0, 200.0);
path.setStroke(Color.BEIGE);
path.getElements().addAll(mT, lT[0], lT[1], lT[2], lT[3]);
path.setOnMouseClicked(new EventHandler<MouseEvent>() {
#Override
public void handle(MouseEvent event) {
final Stage dialog = new Stage();
dialog.initModality(Modality.APPLICATION_MODAL);
dialog.initOwner(Main.prim_stage);
VBox box = new VBox(20);
box.getChildren().add(new Text("Hey"));
Scene s = new Scene(box, 300, 200);
dialog.setScene(s);
dialog.show();
System.out.println("Clicked");
}
});
ctx.setLineWidth(4.0);
ctx.beginPath();
ctx.moveTo(mT.getX(), mT.getY());
for (int i = 0; i < lT.length; i++) {
ctx.lineTo(lT[i].getX(), lT[i].getY());
}
ctx.closePath();
ctx.stroke();
}
EDITED ON SUGGESTION by users.
So his is the main program:
public class Main extends Application {
public static Pane root;
private static Canvas main_canvas;
private static GraphicsContext ctx;
private static Rectangle2D bounds;
private static Scene scene;
public static Stage prim_stage;
#Override
public void start(Stage primaryStage) throws Exception {
primaryStage.setTitle("Switzerland Advertising");
initElements(primaryStage);
Coords.drawMyShape(ctx);
primaryStage.show();
System.out.println("Launched");
}
public static void main(String[] args) {
launch(args);
}
}
Everything is instanciated inside the following function, which works correctly and displays a full screen application with a canvas and a square drawn into it (image at the bottom).
private void initElements(final Stage primaryStage) {
prim_stage = primaryStage;
// ----------------------------------------
bounds = Screen.getPrimary().getVisualBounds();
double w = bounds.getWidth();
double h = bounds.getHeight();
// ----------------------------------------
// init elements of scene
root = new Pane();
main_canvas = new Canvas(w, h);
// ----------------------------------------
// init scene elements
scene = new Scene(root, w, h);
primaryStage.setX(bounds.getMinX());
primaryStage.setY(bounds.getMinY());
primaryStage.setWidth(w);
primaryStage.setHeight(h);
primaryStage.setScene(scene);
// ----------------------------------------
ctx = main_canvas.getGraphicsContext2D();
// set elements in main pane
root.getChildren().add(main_canvas);
// ----------------------------------------
}
So how can I make the pop-up window appear whenever I click inside the region drawn on the canvas?
This is the program
Your path is just a local variabl within your method. It has to be attached to the scene graph in order to get events. But when you attach it to the scene graph, drawing the same path on a canvas also does not make much sense.
I created this very simple example for JavaFX alert dialog for JavaFX8u40.
public class MainApp extends Application
{
public static void main(String[] args)
{
Application.launch(args);
}
private Stage stage;
#Override
public void start(Stage primaryStage) throws Exception
{
Button create = new Button("Create Alert");
create.setTooltip(new Tooltip("Create an Alert Dialog"));
create.setOnAction(e ->
{
createAlert();
});
primaryStage.setScene(new Scene(create));
primaryStage.show();
stage = primaryStage;
}
protected Alert createAlert()
{
Alert alert = new Alert(AlertType.WARNING);
Image image1 = new Image("http://www.mcaprojecttraining.com/images/java-big-icon.png");
ImageView imageView = new ImageView(image1);
alert.setGraphic(imageView);
alert.initModality(Modality.APPLICATION_MODAL);
alert.initOwner(stage);
alert.getDialogPane().setContentText("Some text");
alert.showAndWait()
.filter(response -> response == ButtonType.OK)
.ifPresent(response -> System.out.println("The alert was approved"));
return alert;
}
}
I'm interested how I can set the image on the left side of the dialog.
Did someone manage to change the side of the image?
If you have a look at how the header is constructed, you'll find a GridPane node to layout a Label on the left and a StackPane for the icon.
If you want to reverse the cells order by code, you can do it, but it will be overriden every time updateHeaderArea() is called.
My suggestion is using this public API:
dialogPane.setHeader(Node header);
dialogPane.setGraphic(Node graphic);
providing a header with an icon on the left and a label, and a null graphic.
Using the same approach as DialogPane, we could add another GridPane as header:
protected Alert createAlert(){
Alert alert = new Alert(AlertType.WARNING);
alert.initModality(Modality.APPLICATION_MODAL);
alert.initOwner(stage);
alert.getDialogPane().setContentText("Some text");
DialogPane dialogPane = alert.getDialogPane();
GridPane grid = new GridPane();
ColumnConstraints graphicColumn = new ColumnConstraints();
graphicColumn.setFillWidth(false);
graphicColumn.setHgrow(Priority.NEVER);
ColumnConstraints textColumn = new ColumnConstraints();
textColumn.setFillWidth(true);
textColumn.setHgrow(Priority.ALWAYS);
grid.getColumnConstraints().setAll(graphicColumn, textColumn);
grid.setPadding(new Insets(5));
Image image1 = new Image("http://www.mcaprojecttraining.com/images/java-big-icon.png");
ImageView imageView = new ImageView(image1);
imageView.setFitWidth(64);
imageView.setFitHeight(64);
StackPane stackPane = new StackPane(imageView);
stackPane.setAlignment(Pos.CENTER);
grid.add(stackPane, 0, 0);
Label headerLabel = new Label("Warning");
headerLabel.setWrapText(true);
headerLabel.setAlignment(Pos.CENTER_RIGHT);
headerLabel.setMaxWidth(Double.MAX_VALUE);
headerLabel.setMaxHeight(Double.MAX_VALUE);
grid.add(headerLabel, 1, 0);
dialogPane.setHeader(grid);
dialogPane.setGraphic(null);
alert.showAndWait()
.filter(response -> response == ButtonType.OK)
.ifPresent(response -> System.out.println("The alert was approved"));
return alert;
}
And this is what you will see:
