When opening a JavaFX FileChooser within a Stage (only way to make it modal), there is an annoying "Genie" effect (see code and movie below). How can it be disabled ?
import javafx.application.Platform;
import javafx.embed.swing.JFXPanel;
import javafx.stage.Stage;
import javafx.stage.FileChooser;
import javafx.concurrent.Task;
public class Test {
private static void initFX() {
// This method is invoked on the JavaFX thread
Stage stage = new Stage();
FileChooser fileChooser = new FileChooser();
stage.setMaxHeight(0);
stage.setWidth(0);
stage.setTitle("Choose an file");
stage.setResizable(false);
stage.setAlwaysOnTop(true);
stage.show();
fileChooser.showOpenDialog(stage);
stage.hide();
}
public static void main(String[] args) {
final JFXPanel fxPanel = new JFXPanel();
Platform.runLater(new Runnable() {
#Override
public void run() {
initFX();
}
});
}
}

I am trying to create a Javafx game and I want the user to be able to input their name using a dialogue. The problem is that when I try to position the dialogue using setY() or setX() nothing changes. I should note that I am using an online IDE so if this is the problem please somebody tell me.

setUserName();

Using JavaFX, I am trying to run a program a.out on Terminal of Mac OSX. The following code does not work on Mac. The same code works on Windows by writing cmndM={"cmd","/c","start","a.exe"}. What's wrong on Mac?
protected void onRunClick(ActionEvent evt) throws IOException {
String exeM="./a.out";
Runtime runtime=Runtime.getRuntime();
String[] cmndM= {"/bin/sh","-c",exeM}; Process pm=null; File dirM=new File(pth);
try {
pm=runtime.exec(cmndM, null, dirM);}
}catch (IOException e) {
msg.setText("Error in running simulation.");
}
}
It might be related to location of the file.
I'd have tried with fixed location first, just to be sure it works.
Also, make sure the file is actually there, inside pth.

I have a task to make JavaFX application. When I start it the window should slides smoothly from right side of screen and when I click on "x" button it's should slides out to right side and then finishes.
I found possible to use simple Timeline animation for this. I made the window to slide in, when I run app, but can't figure out how to slide out window.
I tried to handle this defining handler via setOnCloseRequest() method of stage, but stuck with two problems:
can't implement animation
after click on "x" application closed immediately even if I use consume() method of Window event
Code:
public class Main extends Application {
public static void main(String[] args) {
Application.launch(args);
}
#Override
public void start(Stage stage) {
stage.setTitle("Main");
Group root = new Group();
Scene scene = new Scene(root, 300, 250);
stage.setScene(scene);
Rectangle2D primScreenBounds = Screen.getPrimary().getVisualBounds();
stage.setX(primScreenBounds.getMinX() + primScreenBounds.getWidth());
System.out.println(primScreenBounds.getWidth());
stage.setY(primScreenBounds.getMinY());
stage.setWidth(0);
stage.setHeight(primScreenBounds.getHeight());
Timeline timeline = new Timeline();
timeline.setAutoReverse(true);
WritableValue<Double> writableWidth = new WritableValue<Double>() {
#Override
public Double getValue() {
return stage.getWidth();
}
#Override
public void setValue(Double value) {
stage.setWidth(value);
}
};
KeyValue kv = new KeyValue(writableWidth, 600d);
KeyFrame kf = new KeyFrame(Duration.millis(3000), kv);
timeline.getKeyFrames().addAll(kf);
timeline.play();
stage.show();
stage.setOnCloseRequest(new EventHandler<WindowEvent>() {
#Override
public void handle(WindowEvent event) {
event.consume();
}
});
}
}
This works (kind of, it is not very smooth) for me:
import javafx.animation.KeyFrame;
import javafx.animation.KeyValue;
import javafx.animation.Timeline;
import javafx.application.Application;
import javafx.application.Platform;
import javafx.beans.value.WritableValue;
import javafx.event.EventHandler;
import javafx.geometry.Rectangle2D;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.stage.Screen;
import javafx.stage.Stage;
import javafx.stage.WindowEvent;
import javafx.util.Duration;
public class SlidingWindow extends Application {
public static void main(String[] args) {
Application.launch(args);
}
#Override
public void start(Stage stage) {
stage.setTitle("Main");
Group root = new Group();
Scene scene = new Scene(root);
stage.setScene(scene);
Rectangle2D primScreenBounds = Screen.getPrimary().getVisualBounds();
double screenRightEdge = primScreenBounds.getMaxX() ;
stage.setX(screenRightEdge);
System.out.println(primScreenBounds.getWidth());
stage.setY(primScreenBounds.getMinY());
stage.setWidth(0);
stage.setHeight(primScreenBounds.getHeight());
Timeline timeline = new Timeline();
WritableValue<Double> writableWidth = new WritableValue<Double>() {
#Override
public Double getValue() {
return stage.getWidth();
}
#Override
public void setValue(Double value) {
stage.setX(screenRightEdge - value);
stage.setWidth(value);
}
};
KeyValue kv = new KeyValue(writableWidth, 600d);
KeyFrame kf = new KeyFrame(Duration.millis(3000), kv);
timeline.getKeyFrames().addAll(kf);
timeline.play();
stage.show();
stage.setOnCloseRequest(new EventHandler<WindowEvent>() {
#Override
public void handle(WindowEvent event) {
Timeline timeline = new Timeline();
KeyFrame endFrame = new KeyFrame(Duration.millis(3000), new KeyValue(writableWidth, 0.0));
timeline.getKeyFrames().add(endFrame);
timeline.setOnFinished(e -> Platform.runLater(() -> stage.hide()));
timeline.play();
event.consume();
}
});
}
}
The Platform.runLater(...) seems necessary to prevent a slew of NullPointerExceptions when the window is hidden, probably because the animation is causing some system to try to access a stage that no longer exists.
When I add image and text to a button, by default elements are set horizontally. How can I change this behavior to get text under image ?
Set the contentDisplayProperty on the button.
button.setContentDisplay(ContentDisplay.TOP);
Here is an executable example:
import javafx.application.Application;
import javafx.event.*;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.*;
import javafx.scene.image.*;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class ButtonGraphicTest extends Application {
#Override public void start(final Stage stage) throws Exception {
final Label response = new Label();
final ImageView imageView = new ImageView(
new Image("http://icons.iconarchive.com/icons/eponas-deeway/colobrush/128/heart-2-icon.png")
);
final Button button = new Button("I love you", imageView);
button.setStyle("-fx-base: coral;");
button.setContentDisplay(ContentDisplay.TOP);
button.setOnAction(new EventHandler<ActionEvent>() {
#Override public void handle(ActionEvent event) {
response.setText("I love you too!");
}
});
final VBox layout = new VBox(10);
layout.setAlignment(Pos.CENTER);
layout.getChildren().addAll(button, response);
layout.setStyle("-fx-background-color: cornsilk; -fx-padding: 10; -fx-font-size: 20;");
stage.setScene(new Scene(layout));
stage.show();
}
public static void main(String[] args) { launch(args); }
