I've been trying to code this Javafx gui program, however when ever Try to use the getValue() method it ends up saying "it can't find that symbol". Even if I try demos of using the method. How can i get this method to work, is there any other way I can get code to run when the user chooses a choice from the combobox?
not showing my imports, as they are a lot.

I've been trying to make my application to switch between scenes. Here is a copy of part of the code. The credits scene simply has a back button which should return me to the main scene.
When I try to click on credits button on main scene it is becoming white a white screen. I believe that there is a better way to solve this problem could you give me some advices ?
public class Application {
public static void main(String[] args) {
javafx.application.Application.launch(GUI.class);
}
}
public class GUI extends Application {
#Override
public void start(Stage primaryStage) {
Scene mainScene, creditsScene = null;
mainScene = getMainScene(primaryStage, creditsScene);
creditsScene = getCreditsScene(primaryStage, mainScene);
primaryStage.setTitle("Test application");
primaryStage.setScene(mainScene);
primaryStage.show();
}
private Scene getMainScene(Stage primaryStage, Scene creditsScene) {
final Button credits = new Button("Credits");
credits.setOnAction((ActionEvent e) -> {
primaryStage.close();
primaryStage.setScene(creditsScene);
primaryStage.show();
});
VBox x = new VBox(50);
x.setAlignment(Pos.CENTER);
x.getChildren().addAll( run, displayInfo,
label1, displayInfo, textField, submitName, credits, exit);
//scene size
Scene scene = new Scene(x, 650, 900);
return scene;
}
private Scene getCreditsScene(Stage primaryStage, Scene main) {
final Button back = new Button("Back");
back.setOnAction((ActionEvent e) -> {
primaryStage.setScene(main);
});
VBox x = new VBox(50);
x.getChildren().addAll(back);
Scene credits = new Scene(x, 650, 900);
return credits;
}
Try to switch order of strings:
mainScene = getMainScene(primaryStage, creditsScene);
creditsScene = getCreditsScene(primaryStage, mainScene);
here you pass to getMainScene null.
Is it possible to do a simple background "flash" effect with a gradual fade on an arbitrary Node/Region/Pane?
I just want to show a subtle/brief red/white "flash" effect on a VBox (containing a label) to draw attention to it when the label's value changes.
Edit: All examples of this nature I've found so far seem to use a "Shape" (which is a Node), but of course a VBox or a Pane aren't a Shape - so that doesn't help me too much. Calling getShape() on the VBox just returns a null, so that's no help (I guess layout code hasn't been executed yet).
Edit 2:
This ALMOST works, but this dang effect seems to be completely overwriting (I think) everything in the VBox, including the text Label.
ColorInput effect = new ColorInput(0, 0, 900, 25, Paint.valueOf("#FFDDDD"));
Timeline flash = new Timeline(
new KeyFrame(Duration.seconds(0.4), new KeyValue(effect.paintProperty(), Paint.valueOf("#EED9D9"))),
new KeyFrame(Duration.seconds(0.8), new KeyValue(effect.paintProperty(), Paint.valueOf("#E0DDDD"))),
new KeyFrame(Duration.seconds(1.0), new KeyValue(effect.paintProperty(), Paint.valueOf("#DDDDDD"))));
vbox.setEffect(effect);
flash.setOnFinished(e -> vbox.setEffect(null));
flash.play();
Best way would be to provide a custom animation, like this (elaborating on fabian's answer):
#Override
public void start(Stage primaryStage) {
Label label = new Label("Bla bla bla bla");
Button btn = new Button("flash");
VBox box = new VBox(10, label, btn);
box.setPadding(new Insets(10));
btn.setOnAction((ActionEvent event) -> {
//**************************
//this animation changes the background color
//of the VBox from red with opacity=1
//to red with opacity=0
//**************************
final Animation animation = new Transition() {
{
setCycleDuration(Duration.millis(1000));
setInterpolator(Interpolator.EASE_OUT);
}
#Override
protected void interpolate(double frac) {
Color vColor = new Color(1, 0, 0, 1 - frac);
box.setBackground(new Background(new BackgroundFill(vColor, CornerRadii.EMPTY, Insets.EMPTY)));
}
};
animation.play();
});
Scene scene = new Scene(box, 100, 100);
primaryStage.setScene(scene);
primaryStage.show();
}
You could animate a effect, e.g. DropShadow:
#Override
public void start(Stage primaryStage) {
Label label = new Label("Bla bla bla bla");
DropShadow shadow = new DropShadow();
shadow.setColor(Color.RED);
shadow.setSpread(0.75);
Timeline shadowAnimation = new Timeline(
new KeyFrame(Duration.ZERO, new KeyValue(shadow.radiusProperty(), 0d)),
new KeyFrame(Duration.seconds(0.15), new KeyValue(shadow.radiusProperty(), 20d)));
shadowAnimation.setAutoReverse(true);
shadowAnimation.setCycleCount(2);
Button btn = new Button("flash");
btn.setOnAction((ActionEvent event) -> {
Node target = label;
target.setEffect(shadow);
shadowAnimation.setOnFinished(evt -> target.setEffect(null));
shadowAnimation.play();
});
VBox box = new VBox(10, label, btn);
box.setPadding(new Insets(10));
Scene scene = new Scene(box, 100, 100);
primaryStage.setScene(scene);
primaryStage.show();
}
You can create a fake shape and use the FillTransition Interpolator to apply the shape's fill to the control background.
public static void AnimateBackgroundColor(Control control, Color fromColor,Color toColor,int duration)
{
Rectangle rect = new Rectangle();
rect.setFill(fromColor);
FillTransition tr = new FillTransition();
tr.setShape(rect);
tr.setDuration(Duration.millis(duration));
tr.setFromValue(fromColor);
tr.setToValue(toColor);
tr.setInterpolator(new Interpolator() {
#Override
protected double curve(double t) {
control.setBackground(new Background(new BackgroundFill(rect.getFill(), CornerRadii.EMPTY, Insets.EMPTY)));
return t;
}
});
tr.play();
}
I am building a javaFX application.
The example program which is online working well: http://www.java2s.com/Tutorials/Java/JavaFX/1010__JavaFX_Timeline_Animation.htm
I changed it a bit:
I want to have these nice moving circles in the background. That's why I made these tricks:
Main.java:
#Override
public void start(Stage primaryStage) {
try {
// load the FXML resource
FXMLLoader loader = new FXMLLoader(getClass().getResource("Dashboard.fxml"));
// store the root element so that the controllers can use it
StackPane root = new StackPane();
Pane bgRoot = new Pane();
GridPane userRoot = (GridPane) loader.load();
// create and style a scene
Rectangle2D primaryScreenBounds = Screen.getPrimary().getBounds();
BackgroundScene bgScene = new BackgroundScene(root, bgRoot, primaryScreenBounds.getWidth(),
primaryScreenBounds.getHeight(), Color.BLACK);
// TODO CSS load:
// bgScene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
// create the stage with the given title and the previously created
// scene
primaryStage.setFullScreen(true);
primaryStage.setMaximized(true);
primaryStage.setResizable(false);
primaryStage.setMinWidth(primaryScreenBounds.getWidth());
primaryStage.setMinHeight(primaryScreenBounds.getHeight());
primaryStage.setScene(bgScene);
root.getChildren().add(bgRoot);
root.getChildren().add(userRoot);
// show the GUI
primaryStage.show();
userRoot.setPrefHeight(root.getHeight());
userRoot.setPrefWidth(root.getWidth());
} catch (Exception e) {
e.printStackTrace();
}
}
In the above code:
I have a stage with a stack pane.
There is a Pane on the StackPane with the Circles
On that there is a GridPane for controllers.
I made my own Scene as BackgroundScene:
public class BackgroundScene extends Scene {
private Pane bgRoot;
public BackgroundScene(Parent root, Pane bgRoot, double width, double height, Color color) {
super(root, width, height, color);
this.bgRoot = bgRoot;
makeGreenCircleAnimation();
}
public void makeGreenCircleAnimation() {
Group circles = new Group();
for (int i = 0; i < 30; i++) {
Circle circle = new Circle(Math.random() * this.getWidth(), Math.random() * this.getHeight(),
150, Color.web("white", 0.05));
circle.setStrokeType(StrokeType.OUTSIDE);
circle.setStroke(Color.web("white", 0.16));
circle.setStrokeWidth(4);
circles.getChildren().add(circle);
}
circles.setEffect(new BoxBlur(10, 10, 3));
Rectangle colors = new Rectangle(this.getWidth(), this.getHeight(),
new LinearGradient(0f, 1f, 1f, 0f, true, CycleMethod.NO_CYCLE,
new Stop[] { new Stop(0, Color.web("#00ff00")), new Stop(0.14, Color.web("#11ee11")),
new Stop(0.28, Color.web("#22dd22")), new Stop(0.43, Color.web("#33cc33")),
new Stop(0.57, Color.web("#44bb44")), new Stop(0.71, Color.web("#55aa55")),
new Stop(0.85, Color.web("#669966")), new Stop(1, Color.web("#778877")), }));
Group blendModeGroup = new Group(
new Group(new Rectangle(this.getWidth(), this.getHeight(), Color.DARKGREEN), circles), colors);
colors.setBlendMode(BlendMode.OVERLAY);
bgRoot.getChildren().add(blendModeGroup);
Timeline timeline = new Timeline();
makeAnimation(circles, timeline);
timeline.play();
timeline.setOnFinished(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
makeAnimation(circles, timeline);
timeline.play();
}
});
}
void makeAnimation(Group group, Timeline timeline) {
timeline.getKeyFrames().clear();
for (Node node : group.getChildren()) {
timeline.getKeyFrames()
.addAll(new KeyFrame(Duration.ZERO, // set start
// position at 0
new KeyValue(node.translateXProperty(), node.getLayoutX() + node.getTranslateX()),
new KeyValue(node.translateYProperty(), node.getLayoutY() + node.getTranslateY())),
new KeyFrame(new Duration(4000), // set end position at
// 40s
new KeyValue(node.translateXProperty(), Math.random() * this.getWidth()),
new KeyValue(node.translateYProperty(), Math.random() * this.getHeight())));
}
}
}
It contains the code from the tutorial (with minor changes).
I add the circles and everything to the Pane not to a Group (as in
the online example)
The problem is that it is seams to be moving:
The circles are moving to the right (always)
If I change something in the code:
Main.java (instantiating my scene):
BackgroundScene bgScene = new BackgroundScene(root, root, primaryScreenBounds.getWidth(),
primaryScreenBounds.getHeight(), Color.BLACK);
(so giving the circles to the StackPane)
This happens:
You can download the eclipse project:
https://www.dropbox.com/s/dovae0hxdtsnsdo/Test.7z?dl=0
Do you know what is the problem?
Or can you suggest something how I can put the circles nicely behind the button?
I have this simple example with JavaFX tabs:
public class test extends Application
{
private BorderPane root;
// Navigation Utilization
private ActionTabs actiontabs;
#Override
public void start(Stage primaryStage)
{
// Set Main Window Label
primaryStage.setTitle("Desktop Client");
Image iv = new Image(getClass().getResource("/images/internet-icon.png").toExternalForm());
primaryStage.getIcons().add(iv);
root = new BorderPane();
root.setLeft(getLeftHBox(primaryStage, root));
Scene scene = new Scene(root, 1000, 1000, Color.WHITESMOKE); // Set main Stage color
primaryStage.setScene(scene);
Rectangle2D primaryScreenBounds = Screen.getPrimary().getVisualBounds();
// Set Stage boundaries to visible bounds of the main screen
primaryStage.setX(primaryScreenBounds.getMinX());
primaryStage.setY(primaryScreenBounds.getMinY());
primaryStage.setWidth(primaryScreenBounds.getWidth()); // Maximum width of the display
primaryStage.setHeight(primaryScreenBounds.getHeight()); // Maximum height of the display
primaryStage.show();
}
public static void main(String[] args)
{
launch(args);
}
private HBox getLeftHBox(Stage primaryStage, BorderPane root)
{
HBox hbox = new HBox();
TabPane tabPane = new TabPane();
BorderPane mainPane = new BorderPane();
tabPane.setStyle("-fx-font-size: 12pt;"); // Set global size for the font
// Create Tabs
Tab tabA = new Tab();
tabA.setText("Main Component");
tabA.setStyle("-fx-font-size: 12pt;"); // Set size of the tab name
tabA.setClosable(false);
// Add something in Tab
StackPane tabA_stack = new StackPane();
tabA_stack.setAlignment(Pos.CENTER);
tabA_stack.getChildren().add(new Label("Label#Tab A"));
tabA.setContent(tabA_stack);
tabPane.getTabs().add(tabA);
Tab tabB = new Tab();
tabB.setText("Second Component");
tabB.setStyle("-fx-font-size: 12pt;"); // Set size of the tab name
tabB.setClosable(false);
// Add something in Tab
StackPane tabB_stack = new StackPane();
tabB_stack.setAlignment(Pos.CENTER);
tabB_stack.getChildren().add(new Label("Label#Tab B"));
tabB.setContent(tabB_stack);
tabPane.getTabs().add(tabB);
Tab tabC = new Tab();
tabC.setText("Last Component");
tabC.setStyle("-fx-font-size: 12pt;"); // Set size of the tab name
tabC.setClosable(false); // da se mahne opciqta da se zatvarq tab
// Add something in Tab
StackPane tabC_vBox = new StackPane();
tabC_vBox.setAlignment(Pos.CENTER);
tabC_vBox.getChildren().add(new Label("Label#Tab C"));
tabC.setContent(tabC_vBox);
tabPane.getTabs().add(tabC);
mainPane.setCenter(tabPane);
mainPane.setPrefSize(300, 500);
//mainPane.setLayoutX(5); // Horizontal Position
mainPane.setLayoutY(32); // Vertical Position
hbox.getChildren().addAll(mainPane);
return hbox;
}
}
I want when I double click on a tab name to maximize the size of the body of the tab and make it the same width and height as the size of the application. Similar for example to Eclipse IDE tabs. Is this possible with JavaFX?
EDIT
This is the code that I have tested.
public BorderPane initNavigation(Stage primaryStage)
{
VBox stackedTitledPanes = createStackedTitledPanes();
ScrollPane scroll = makeScrollable(stackedTitledPanes);
final TabPane tabPane = new TabPane();
final BorderPane mainPane = new BorderPane();
final Rectangle2D primaryScreenBounds = Screen.getPrimary().getVisualBounds();
tabPane.setStyle("-fx-font-size: 12pt;"); // Set global size for the font
// Create Tabs
Tab tabA = new Tab();
tabPane.setOnMouseClicked(new EventHandler<MouseEvent>()
{
private double sizeX, sizeY;
private boolean first = true;
#Override
public void handle(MouseEvent me)
{
if (first)
{
sizeX = mainPane.getWidth();
sizeY = mainPane.getHeight();
first = false;
}
if (me.getButton().equals(MouseButton.PRIMARY) && me.getClickCount() % 2 == 0)
{
if (sizeX != mainPane.getWidth() || sizeY != mainPane.getHeight())
{
mainPane.setPrefSize(sizeX, sizeY);
}
else
{
mainPane.setPrefSize(primaryScreenBounds.getWidth(), primaryScreenBounds.getHeight());
//mainPane.toFront();
}
}
}
});
tabA.setText("Main Component");
tabA.setContextMenu(makeTabContextMenu(tabA, tabPane)); // Set right mouse click menu
// Add something in Tab
StackPane tabA_stack = new StackPane();
tabA_stack.setAlignment(Pos.CENTER);
tabA_stack.getChildren().add(scroll);
tabA.setContent(tabA_stack);
tabPane.getTabs().add(tabA);
Tab tabB = new Tab();
tabB.setText("Second Component");
tabB.setContextMenu(makeTabContextMenu(tabB, tabPane)); // Set right mouse click menu
// Add something in Tab
StackPane tabB_stack = new StackPane();
tabB_stack.setAlignment(Pos.CENTER);
tabB_stack.getChildren().add(new Label("Label#Tab B"));
tabB.setContent(tabB_stack);
tabPane.getTabs().add(tabB);
Tab tabC = new Tab();
tabC.setText("Last Component");
tabC.setContextMenu(makeTabContextMenu(tabC, tabPane)); // Set right mouse click menu
// Add something in Tab
StackPane tabC_vBox = new StackPane();
tabC_vBox.setAlignment(Pos.CENTER);
tabC_vBox.getChildren().add(new Label("Label#Tab C"));
tabC.setContent(tabC_vBox);
tabPane.getTabs().add(tabC);
mainPane.setCenter(tabPane);
mainPane.setPrefSize(300, 500);
//mainPane.setLayoutX(5); // Horizontal Position
mainPane.setLayoutY(32); // Vertical Position
scroll.setPrefSize(395, 580);
scroll.setLayoutX(5);
scroll.setLayoutY(32);
return mainPane;
}
The problem is how I can cover the stage with the tab code when I double click on the tab name?
You required to add few lines to your code, here is a sample for you,
.....
Tab tabA = new Tab();
Label tabALabel = new Label("Main Component");
tabA.setGraphic(tabALabel);
tabALabel.setOnMouseClicked(new EventHandler<MouseEvent>() {
#Override
public void handle(MouseEvent mouseEvent) {
if (mouseEvent.getButton().equals(MouseButton.PRIMARY)) {
if (mouseEvent.getClickCount() == 2) {
mainPane.setPrefSize(500, 500); //Your required size
}
}
}
});
....
Try this, and tell if there's any difficulty.
You could create another BorderPane which contains your root = new BorderPane();
in Center, and replace it with the Tabpanel on doubleclick.
Resulting in:
rootRoot = new BorderPane();
BorderPane root = new BorderPane();
root.setLeft(getLeftHBox(primaryStage, root));
rootRoot.setCenter(root);
Scene scene = new Scene(rootRoot, 1000, 1000, Color.WHITESMOKE); // Set main Stage color
with "rootRoot" being the new root (great Name, i know ^^), and
Label tabALabel=new Label("Label#Tab A");
tabALabel.setOnMouseClicked(new EventHandler<MouseEvent>() {
#Override
public void handle(MouseEvent mouseEvent) {
if (mouseEvent.getButton().equals(MouseButton.PRIMARY)) {
if (mouseEvent.getClickCount() == 2) {
//mainPane.setPrefSize(500, 500); //Your required size
rootRoot.setCenter(mainPane);
}
}
}
});
for maximizing.
I have a pie chart where i have added a mouse listener using this guide:
Oracle guide to pie chart
However when i run my program and click on the chart it doesnt do anything.
I have tried to System.out.println(caption.getText()); and the text of the label is correct however the label is just not showing up.
My code is as following:
public void start(Stage stage) {
Scene scene = new Scene(new Group());
stage.setTitle("Imported Fruits");
stage.setWidth(500);
stage.setHeight(500);
ObservableList<PieChart.Data> pieChartData =
FXCollections.observableArrayList(
new PieChart.Data("Grapefruit", 13),
new PieChart.Data("Oranges", 25),
new PieChart.Data("Plums", 10),
new PieChart.Data("Pears", 22),
new PieChart.Data("Apples", 30));
final PieChart chart = new PieChart(pieChartData);
chart.setTitle("Imported Fruits");
((Group) scene.getRoot()).getChildren().add(chart);
final Label caption = new Label("");
caption.setTextFill(Color.DARKORANGE);
caption.setStyle("-fx-font: 24 arial;");
for (final PieChart.Data data : chart.getData()) {
data.getNode().addEventHandler(MouseEvent.MOUSE_PRESSED,
new EventHandler<MouseEvent>() {
#Override public void handle(MouseEvent e) {
caption.setTranslateX(e.getSceneX());
caption.setTranslateY(e.getSceneY());
caption.setText(String.valueOf(data.getPieValue()) + "%");
caption.setVisible(true);
}
});
}
stage.setScene(scene);
stage.show();
}
}
Can anyone tell me what i did wrong?
You forgot to add the label 'caption' to the list of children in your root node :-)
public void start(Stage stage) {
Scene scene = new Scene(new Group());
stage.setTitle("Imported Fruits");
stage.setWidth(500);
stage.setHeight(500);
ObservableList<PieChart.Data> pieChartData =
FXCollections.observableArrayList(
new PieChart.Data("Grapefruit", 13),
new PieChart.Data("Oranges", 25),
new PieChart.Data("Plums", 10),
new PieChart.Data("Pears", 22),
new PieChart.Data("Apples", 30));
final PieChart chart = new PieChart(pieChartData);
chart.setTitle("Imported Fruits");
final ObservableList<Node> children = ((Group) scene.getRoot()).getChildren();
children.add(chart);
final Label caption = new Label("");
caption.setTextFill(Color.DARKORANGE);
caption.setStyle("-fx-font: 24 arial;");
children.add(caption);
for (final PieChart.Data data : chart.getData()) {
data.getNode().addEventHandler(MouseEvent.MOUSE_PRESSED,
new EventHandler<MouseEvent>() {
#Override public void handle(MouseEvent e) {
caption.setTranslateX(e.getSceneX());
caption.setTranslateY(e.getSceneY());
caption.setText(String.valueOf(data.getPieValue()) + "%");
caption.setVisible(true);
}
});
}
stage.setScene(scene);
stage.show();
}
I have made the above change and can verify that it works (as depicted by the image below)
no need for that, you just have to add caption, here:
Change this line :((Group) scene.getRoot()).getChildren().addAll(chart);
to :((Group) scene.getRoot()).getChildren().addAll(chart,caption);
