I need to bring to front JavaFX FXML window from itself. Something like this:
procedure (boolean close)
{
if(close)
current_window.toFront();
}
How should I get this window(scene) ?
Try this
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.VBox;
import javafx.scene.text.Font;
import javafx.scene.text.Text;
import javafx.stage.Stage;
public class Main extends Application {
#Override
public void start(Stage stage) {
Text text = new Text("!");
text.setFont(new Font(40));
VBox box = new VBox();
box.getChildren().add(text);
final Scene scene = new Scene(box,300, 250);
scene.setFill(null);
stage.setScene(scene);
stage.show();
stage.toFront();
}
public static void main(String[] args) {
launch(args);
}
}
If you have access to any of the nodes, you can use the following
((Stage)node.getScene().getWindow()).toFront();

I am trying to set the mouse to a pointer when a hover event is detected but the cursor does not change. If anyone can tell me what I am doing wrong I would be so grateful.
package replit;
import javafx.application.Application;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.VBox;
import javafx.geometry.Pos;
public class Main extends Application
{
#Override
public void start(Stage primaryStage) {
VBox vbox = new VBox();
vbox.setSpacing(20);
button button = new Button("Click");
button.setAlignment(Pos.CENTER);
vbox.getChildren().add(button);
Scene scene = new Scene(vbox, 300, 200);
scene.getStylesheets().add("Style.css");
primaryStage.setTitle("A Simple Scene!");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
The CSS
.button:hover{
-fx-cursor: pointer;
}
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;
import javafx.scene.control.*;
public class textareasss extends Application {
#Override
public void start(Stage stage) throws Exception {
GridPane p = new GridPane();
TextArea tx= new TextArea();
p.add(tx,0,0);
Scene sce = new Scene(p,600,600);
stage.setScene(sce);
stage.show();
}
}

Everytime i paste text in javafx Text Area or TextField, the text is not displayed but rather symbols like this:????.
I ran your code and it works, nothing wrong with JavaFX not accepting fonts or languages
this is what i used :
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TextArea;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;
public class Main extends Application {
#Override
public void start(Stage stage) throws Exception{
GridPane gridpane = new GridPane();
TextArea text= new TextArea();
gridpane.add(text,0,0);
Scene scene = new Scene(gridpane,600,600);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
and this is the output i got :
TextArea containing text in many languages
I have this whole mess of Controls and Transitions in the Scene, and whenever an error or message is made, I call FormBuilder.say(String x).
The sample included doesn't error as much, because it's empty. But when all the stuff are active, the pop up from FormBuilder.say(String x) comes out as a mess.
If I wait long enough, attempt to interact, or if I minimize then restore the Stage, it loads properly. But many times, it's just blank.
My laptop runs Ubuntu 15.10, with approx 2GB RAM. No Video Card.
Included is a screen cap of the messy picture.
Included is the code that's affected during the bug. I've striped out some of the less suspected parts. (EDITED)

I am trying to run this application in which I used event-handling and it won't compile and won't show anything. I am currently using NetBeans 8.1. What is that I did wrong. Also it is not showing any errors.
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.Button;

public class event extends Application {
public void start(Stage primaryStage)
{
HBox pane = new HBox();
pane.setAlignment(Pos.CENTER);
Button btOk = new Button("OK");
Button btCancel = new Button("Cancel");
OkHandlerClass handler1 = new OkHandlerClass();
btOk.setOnAction(handler1);
CancelHandlerClass handler2 = new CancelHandlerClass();
pane.getChildren().addAll(btOk, btCancel);
Scene scene = new Scene(pane);
primaryStage.setTitle("Handle the fucking event");
primaryStage.setScene(scene);
primaryStage.show();
}
class OkHandlerClass implements EventHandler<ActionEvent>{
public void handle(ActionEvent e) {
System.out.println("OK button clicked");
}
}

I'm trying to create image gallery and use some image animations. Problem is with ImageView. I would like to play() RotateTransition from some method and call this method any time but it's not working at all. There should be some issue with threads but even if it is called from new thread nothing is happening. Is there any solution how to work with ImageView and Transitions generally?
public class ImageGallery extends ImageView{
RotateTransition rt;
public ImageGallery() {
setImage(new Image("/img/01.jpg"));
setPreserveRatio(true);
rt = new RotateTransition(Duration.millis(800), this);
rt.setByAngle(90);
//this works but not what I need
//fitWidthProperty().addListener(e -> rt.play());
}
public void rotateRight(){
rt.play(); //nothing
//run later is not working too
//Platform.runLater(new ViewTransition(this));
}
}
Thanks
