KeyValue class gives error in javafx? how i fix it - javafx

KeyValue class gives error in javafx? I also implements all the abstract method but still face issue?
package at_collection;
import java.net.URL;

import java.util.logging.Logger;

import javafx.scene.layout.AnchorPane;
import javafx.scene.layout.StackPane;
import javafx.util.Duration;
import javax.xml.crypto.dsig.keyinfo.KeyValue;
public class Scene1Controller implements Initializable {
#FXML
private StackPane parent;
#FXML
private AnchorPane child1;
#FXML
private Button btn1;
#Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
}
#FXML
private void load1(ActionEvent event) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("Scene2.fxml"));
Scene scene = btn1.getScene();
root.translateYProperty().set(scene.getHeight());
parent.getChildren().add(root);
Timeline timeline = new Timeline();
KeyValue kv = new KeyValue(root.translateYProperty(), 0, Interpolator.EASE_IN); // Here is the problem
KeyFrame kf = new KeyFrame(Duration.seconds(1), kv);
timeline.getKeyFrames().add(kf);
timeline.setOnFinished(t -> {
parent.getChildren().remove(child1);
});
timeline.play();
}
}
The stack trace is not print. Because of the compile-time error. i'm actually implements this "https://www.youtube.com/watch?v=cqskg3DYH8g"
Here is the output of this code

This is because of the Wrong Import "import javax.xml.crypto.dsig.keyinfo.KeyValue"
Import this one "import javafx.animation.KeyValue;"

How can i add scroll!??? Please Click to show pic
when i put ScrollPane in myCode,unfortunatly dose not have good performance and myscroll dosnt cover all my Line
this Code is Below
package schedul;
import java.io.IOException;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.control.ScrollPane;
import javafx.scene.layout.AnchorPane;

import javafx.scene.shape.Circle;

import javafx.scene.text.Text;
import javafx.stage.Stage;
public class scene11 extends Application {
#Override
public void start(Stage primaryStage) throws IOException {
AnchorPane root=FXMLLoader.
<AnchorPane>load(getClass().getResource("/schedul/scene1.fxml"));
Line line=new Line();
Text text=new Text();
line.setStartX(50);
line.setStartY(50);
line.setEndX(800);
line.setEndY(50);
root.getChildren().add(line);
HBox content = new HBox(root);
ScrollPane scroller = new ScrollPane(content);
scroller.setFitToWidth(true);
Scene scene= new Scene(new BorderPane(scroller, null, null, null,
null));
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
I expected the scroll to be created automatically
I took your sample code and removed the irrelevant bits.
All you need to do to make an AnchorPane scrollable is put it in a ScrollPane. This is demonstrated by the sample below. The same will work for any other Pane type.
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.ScrollPane;
import javafx.scene.layout.AnchorPane;
import javafx.scene.shape.Line;
import javafx.stage.Stage;
public class ScrollApp extends Application {
#Override
public void start(Stage stage) {
stage.setScene(
new Scene(
new ScrollPane(
new AnchorPane(
new Line(50, 50, 800, 50)
)
)
)
);
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
After the application launches, by default, it will size to fit all of the content, so you won't see the scroll bars. If you make the window smaller horizontally, you will see the horizontal scrollbar, and similarly for the vertical direction.

Request fix functionality

MY TASK : Write a JavaFX GUI application that allows the user to pick a set of pizza toppings using a set of check boxes. Assuming each topping cost 50 cents, and a plain pizza costs $10, display the cost of the pizza. Note that, once a topping is checked or unchecked, the cost of pizza should update automatically.
FIX REQUEST : my pizza cost calculator fails to add cost for topping properly
For example, Extracheese checked and unchecked resulted in below base price $10 (ie; $7)

class PizzaCost extends VBox {
private CheckBox ExtraCheeseCheckBox;
private CheckBox GreenPepperCheckBox;
private Label TotalPizzaCost;
public double pizzaCost = 10.0;
public PizzaCost(){
Font font = new Font(13);
ExtraCheeseCheckBox = new CheckBox("Extra Cheese");
ExtraCheeseCheckBox.setOnAction(this::processCheckBoxAction);
GreenPepperCheckBox = new CheckBox("GreenPepper");
GreenPepperCheckBox.setOnAction(this::processCheckBoxAction);
TotalPizzaCost = new Label(pizzaCost +"");
TotalPizzaCost.setFont(font);
HBox options = new HBox(ExtraCheeseCheckBox,GreenPepperCheckBox);
getChildren().addAll(options,TotalPizzaCost);
}
public void processCheckBoxAction (ActionEvent event){
if (ExtraCheeseCheckBox.isSelected()){
pizzaCost += 0.5;
}
else {
pizzaCost -= 0.5;
}
TotalPizzaCost.setText(pizzaCost+"");
}
}
The following code works for me. The pizza cost never goes below $10.

primaryStage.setScene(scene);
primaryStage.setTitle("Pizza Cost");
primaryStage.show();
}
private CheckBox getCheckBox(String text) {
CheckBox cb = new CheckBox(text);
cb.setOnAction(this::processCheckBoxAction);
return cb;
}
private void processCheckBoxAction(ActionEvent event) {
CheckBox cb = (CheckBox) event.getSource();
if (cb.isSelected()) {
pizzaCost += TOPPING_COST;
}
else {
pizzaCost -= TOPPING_COST;
}
totalPizzaCostLabel.setText(PIZZA_COST + COST_FORMAT.format(pizzaCost));
}
public static void main(String[] args) {
launch(args);

Error when making a photo slideshow in JavaFX

I'm currently following a tutorial on YouTube to make a photo slide show in JavaFX. Here is my controller code:

I have an error on this line:

EventHandler error when I try to create a play button for a video media player in Java

I don't understand why eclipse won't recognize the EventHandler since I have imported it. Here is my code:
package application;
import java.awt.event.ActionEvent;
import com.sun.glass.ui.Accessible.EventHandler;
import javafx.geometry.Insets;
import javafx.geometry.Pos;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.Slider;
import javafx.scene.layout.HBox;
import javafx.scene.layout.Priority;
import javafx.scene.media.MediaPlayer;
public class MediaBar extends HBox {
Slider time =new Slider();
Slider vol =new Slider();
Button playButton=new Button("||");
Label volume=new Label("Volume");
MediaPlayer player;
public MediaBar(MediaPlayer play){
player=play;
setAlignment(Pos.CENTER);
setPadding(new Insets(5,10,5,10));
vol.setPrefWidth(70);
vol.setMin(30);
vol.setValue(100);
HBox.setHgrow(time, Priority.ALWAYS);
playButton.setPrefWidth(30);
getChildren().add(playButton);
getChildren().add(time);
getChildren().add(volume);
getChildren().add(vol);
playButton.setOnAction(new EventHandler<ActionEvent>(){
public void handle(ActionEvent e){
Status status=player.getStatus();
if(status==Status.Playing){
if(player.getCurrentTime().greaterThanOrEqualTo(player.getTotalDuration())){
player.seek(player.getStartTime());
player.play();
}
else{
player.pause();
playerButton.setText(">");
}
}
if(status==Status.PAUSE ||status==Status.HALTED||status==Status.STOPPED){
player.play();
playButton.setText("||");
}
}
});
}
}
Here is the error message :
The type Accessible.EventHandler is not generic; it cannot be parameterized with arguments <ActionEvent>
What am I doing wrong?
Correct the import you are using JavaFX not Swing/AWT:
replace :
import java.awt.event.ActionEvent;
import com.sun.glass.ui.Accessible.EventHandler;
with :
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
Avoid automatic importing or pay attention to what you are importing !

Create a webview from a button in JavaFX

I have the following simple code where I have an horizontal block where there are two buttons, the remain part is empty. Now, I would like to view a Webview inside the free part after the user press the "current" button. I already did something similar but I wasn't able to manage the layout because it was a Jframe + JavaFX. I thought to re-build totally in JavaFx , for this reason I want to put the webview in a jfxPanel(I think it's the best solution, any other suggest is really appreciate). I should see the webview when I press the button , in this case current, for this reason I create an handle. So, How can I do it?
Thanks in advance

});

stage.setScene(new Scene(layout));
stage.show();
}
