Access to Javafx elements from another class without FXML

I am using Javafx8 and lets say i have created many ui items (like buttons and so on...). I thought its a good idea to put all EventHandler for these buttons into a separates class. My question is: How can i get access from an EventHandler to any button, e.g. to diable it or to manipulate it on any other way.
Here is a minimum example with two buttons and a separate class for EventHandlers
Let's say this is my Start class:
public class App extends Application
{
#Override
public void start(Stage primaryStage) throws Exception {
Button b1 = new Button();
b1.setOnAction(ListenerClass.createB1Event());
Button b2 = new Button();
b2.setOnAction(ListenerClass.createB2Event());
VBox vbox = new VBox(b1, b2);
Scene scene = new Scene(vbox, 200, 200);
primaryStage.setTitle("App");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main( String[] args )
{
Application.launch(args);
}
}
And my (separate) listener class:
public class ListenerClass {
public static EventHandler<ActionEvent> createB1Event() {
return new EventHandler<ActionEvent>() {
public void handle(ActionEvent t) {
//Access here to b1 and b2...
//Deactivate B1
//Activate B2
}
};
}
public static EventHandler<ActionEvent> createB2Event() {
return new EventHandler<ActionEvent>() {
public void handle(ActionEvent t) {
//Access here to b1 and b2...
//Activate B1
//Dectivate B2
}
};
}
}
Thanks

So based on your principal. You want the button that is located in a vbox and got pressed to be disabled and all other buttons from that vbox to be enabled.
And your problem is how to find button that got pressed.
You need to use ActionEvent.getSource() method.
Heres how I'd code it....
This is Start class:
public class Main extends Application {
#Override
public void start(Stage primaryStage) throws Exception {
VBox vbox = new VBox();
Button b1 = addNewButton("Button1",vbox);
Button b2 = addNewButton("Button2",vbox);
Button b3 = addNewButton("Button3",vbox);
Scene scene = new Scene(vbox, 200, 200);
primaryStage.setTitle("App");
primaryStage.setScene(scene);
primaryStage.show();
}
public static Button addNewButton(String label, VBox ownerVBox){
Button button = new Button(label);
ownerVBox.getChildren().add(button);
button.setOnAction(ListenerClass.createBEvent());
return button;
}
public static void main(String[] args) {
launch(args);
}
}
Listener class:
public class ListenerClass {
public static EventHandler<ActionEvent> createBEvent() {
return new EventHandler<ActionEvent>() {
public void handle(ActionEvent t) {
Button b = (Button) t.getSource();
VBox vbox =(VBox) b.getParent();
vbox.getChildren().forEach(button-> {
button.setDisable(false);
});
b.setDisable(true);
}
};
}
}

When trying to add items to a JavaFX TableView through an ObservableList, the TableView items won't show

I'm making a grocery list app, and it has the feature to add items to the list(a tableview) along with the # of items and price. THe thing is, it works(because the tableview doesnt say "No content in table") But the table is blank. Any suggestions?
Code:
package listproject;
public class Main extends Application{
public Node getNodeByRowColumnIndex(final int row,final int column,GridPane gridPane) {
Node result = null;
ObservableList<Node> childrens = gridPane.getChildren();
for(Node node : childrens) {
if(gridPane.getRowIndex(node) == row && gridPane.getColumnIndex(node) == column) {
result = node;
break;
}
}
return result;
}
ObservableList<Product> data =
FXCollections.observableArrayList(

You never set the cellValueFactorys for the table's columns. You need to do this to specify the part of the items that should be displayed in the column.
An example with anonymus classes as cellValueFactorys can be found here.
Using PropertyValueFactory could reduce the amount of code needed. More about this here.
A tutorial can be found here: https://docs.oracle.com/javase/8/javafx/user-interface-tutorial/table-view.htm

How to open an image listed in a TilePane on button click

I have a TilePane that lists images from different directories on my hard disk. I would like, when an image on the TilePane is clicked:
To open the folder containing the image,
To open the image, for example, with the default program set to open that type of image file.
What I have so far only gives me something like ImageResources/faviicon.png when an image is clicked.
Is there any way I can use, for example, ImageResources/faviicon.png to do 1. and 2. above? Thank you all.
This is the Class I have:
public class TilePaneExample extends Application {
#Override
public void start(Stage primaryStage) {
VBox root = new VBox(30);
String[] imageResources = new String[]{
//loading images
"ImageResources/facebook.png",
"ImageResources/faviicon.png",
"ImageResources/jquery-logo.png",
"ImageResources/linkedin_32.png",
"ImageResources/loading1.png",
"ImageResources/twitter.png",
"ImageResources/twitter_32.png",
"ImageResources/wp.png",};
VBox vb = new VBox(20);
Text text4Tile = new Text("Images in TilePane");
text4Tile.setFont(Font.font("Calibri", FontWeight.BOLD, 30));
text4Tile.setUnderline(true);
VBox.setMargin(text4Tile, new Insets(10, 0, 0, 10));
//creating Flow Pane
TilePane tilePane = new TilePane();
tilePane.setHgap(5);
tilePane.setVgap(5);
for (final String imageResource : imageResources) {
Image image = new Image(getClass().getResourceAsStream(imageResource));
ImageView imageView = new ImageView(image);
imageView.setOnMouseClicked(new EventHandler<MouseEvent>() {
#Override
public void handle(MouseEvent event) {
System.out.println("You clicked: " + imageResource);
}
});
tilePane.getChildren().add(imageView);
}
vb.getChildren().addAll(text4Tile, tilePane);
root.getChildren().addAll(vb);
primaryStage.setTitle("TilePane Example");
Scene scene = new Scene(root, 300, 150);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Update:
Following DarkDarker's advice, I did this:
imageView.setOnMouseClicked(new EventHandler<MouseEvent>() {
#Override
public void handle(MouseEvent event) {
try {
System.out.println("You clicked: " + imageResource);
File f = new File(imageResource);
System.out.println(f.getAbsolutePath());
Desktop.getDesktop().open(f.getParentFile());
} catch (IOException ex) {
Logger.getLogger(TilePaneExample.class.getName()).log(Level.SEVERE, null, ex);
}
}
});
I, however, get this error:
java.lang.IllegalArgumentException: The file: ImageResources doesn't exist.
at java.awt.Desktop.checkFileValidation(Desktop.java:209)
at java.awt.Desktop.open(Desktop.java:270)

for (final String imageResource : imageResources) {
String imagePath = getClass().getResource(imageResource).toExternalForm();
ImageView imageView = new ImageView(new Image(imagePath));
imageView.setOnMouseClicked(new EventHandler<MouseEvent>() {
#Override
public void handle(MouseEvent event) {
System.out.println("You clicked: " + imagePath);
File imageFile = new File(imagePath);
Desktop.getDesktop().open(imageFile.getParentFile()); // open a folder in explorer
Desktop.getDesktop().open(imageFile); // open file with system preferred program
}
});
tilePane.getChildren().add(imageView);
}

JavaFX ChoiceBox ContextMenu Position

I am new to stackoverflow and also to Java programming, though I do have some small programming background.
I am building a little program using JavaFX 8.0.0-b132 and JavaSE 8...
The program has a GUI and this GUI has a ChoiceBox. The architecture for the layout is:
AnchorPane - VBox - TitledPane - GridPane - HBox - ChoiceBox
I have modified the ChoiceBox extensively using CSS.
Everything is working as it should except for one problem:
When I start the program and open the ChoiceBox (per mouse click or with show()) for the first time, it will display it's ContextMenu at the bottom edge as it should; however, when I close and open it again (with mouse or programmatically) it will display the ContextMenu on top of the ChoiceBox open-button (wrong y position), such that the bottom of the currently selected cell coincides with the bottom of the open-button (meaning it will change position after I select another cell and open it again).
How do I prevent this and make the ContextMenu appear always at the bottom as it does at first?
Here is a snippet of the GUI part of the program with the affected control:
EDIT: problem solved: apparently this behavior is the intended ChoiceBox behavior; I posted in the JavaFX forums that it would be better to make the popup behave like that from the start i.e. the first time it is opened so as not to seem buggy.

Issue with JavaFX PieChart

I have an application with checkBox and 2 animated charts: Pie and Bar charts.
When checkBox is checked, method which adds new data to a chart is fired.
When checkBox is *un*checked, method which removes data from a chart is fired.
Everything is ok when i click a checkbox not very fast. But if i'll click checkbox again before its animation is finished, i recieve this one error:
java.lang.NullPointerException

And this all happens only with PieChart. BarChart works normally.
Here is a method for checkBox onAction event:
public void OnCheckFired(ActionEvent event) {
Boolean b = checkBox.isSelected();
chart.modifyChart(currentChart,b);
}
Thant is a code, which is fired, for modification of pie chart:
#Override
public void makeModifications(Chart chart, Boolean b) {
PieChart pie = (PieChart) chart;
ObservableList<PieChart.Data> pieChartData = pie.getData();
pieChartData = modify(b, pieChartData);
pie.setData(pieChartData);
}
private ObservableList<Data> modify(Boolean b, ObservableList<PieChart.Data> pieChartData) {
if (b) {
pieChartData.add(new PieChart.Data("newValue", 34));
} else {
int size = pieChartData.size() - 1;
pieChartData.remove(size);
}
return pieChartData;
}

I have modified the code attached to the bug issue which is Sergey mentioned in his answer. Replaced the button with checkbox that is being disabled while the animation is playing and extra half second when the animation finished. It behaves this way every time when the selection changed.
public class Tdesst extends Application {
private void init(Stage primaryStage) {
VBox root = new VBox();
Scene scene = new Scene(root);
primaryStage.setScene(scene);
final ObservableList<PieChart.Data> pieChartData = FXCollections.observableArrayList(
new PieChart.Data("Sun", 20),
new PieChart.Data("IBM", 12),
new PieChart.Data("HP", 25),
new PieChart.Data("Dell", 22),
new PieChart.Data("Apple", 30));
final PieChart chart = new PieChart(pieChartData);
final CheckBox chkbox = new CheckBox("add/remove data");
final Timeline animation = new Timeline(
new KeyFrame(Duration.seconds(.5),
new EventHandler<ActionEvent>() {
#Override public void handle(ActionEvent actionEvent) {
chkbox.setDisable(false);
}
}));
animation.setCycleCount(1);
chkbox.selectedProperty().addListener(new ChangeListener<Boolean>() {
#Override
public void changed(ObservableValue<? extends Boolean> arg0, Boolean oldVal, Boolean newVal) {
chkbox.setDisable(true);
if (newVal) {
pieChartData.add(new PieChart.Data("newValue", 34));
} else {
pieChartData.remove(pieChartData.size() - 1);
}
animation.play();
}
});
root.getChildren().add(chart);
root.getChildren().add(chkbox);
}
#Override
public void start(Stage primaryStage) throws Exception {
init(primaryStage);
primaryStage.show();
primaryStage.setTitle(VersionInfo.getRuntimeVersion());
}
public static void main(String[] args) {
launch(args);
}
}
Or you can totally disable animating by
chart.setAnimated(false);

Unfortunately you found a bug. I've filed it as http://javafx-jira.kenai.com/browse/RT-21783
Meanwhile as a workaround you can disable checkbox for a second after each click.
