I have a dynamic gridview. I created a custom design for GridView items. But since the number of columns is static, the blank space increases when the window increases(sorry my english is bad)
default window size:
and how it looks when the screen is enlarged:
public void initgrit( ){
noBarcodes = new ArrayList<>(products());
int col = 0;
int row =0;
for (ProductNoBarcode noBarcode: noBarcodes){
try {
FXMLLoader fxmlLoader = new FXMLLoader();
fxmlLoader.setLocation(getClass().getResource("/fxml/testView.fxml"));
VBox vBox = fxmlLoader.load();
testView testView1 = fxmlLoader.getController();
testView1.setInfo(noBarcode);
if (col == 3){
col=0;
++row;
}
gridPane.add(vBox,col++,row);
GridPane.setMargin(vBox,new Insets(10,10,10,10));
} catch (IOException e) {
throw new RuntimeException(e);
}
}
}

Looking at this code they show a way to display a new window after a login. When username and password are correct it opens new dialog. I want a button click to open new dialog, without checking for username and password.
If you just want a button to open up a new window, then something like this works:
btnOpenNewWindow.setOnAction(new EventHandler<ActionEvent>() {
public void handle(ActionEvent event) {
Parent root;
try {
root = FXMLLoader.load(getClass().getClassLoader().getResource("path/to/other/view.fxml"), resources);
Stage stage = new Stage();
stage.setTitle("My New Stage Title");
stage.setScene(new Scene(root, 450, 450));
stage.show();
// Hide this current window (if this is what you want)
((Node)(event.getSource())).getScene().getWindow().hide();
}
catch (IOException e) {
e.printStackTrace();
}
}
}
I use the following method in my JavaFX applications.
newWindowButton.setOnMouseClicked((event) -> {
try {
FXMLLoader fxmlLoader = new FXMLLoader();
fxmlLoader.setLocation(getClass().getResource("NewWindow.fxml"));
/*
* if "fx:controller" is not set in fxml
* fxmlLoader.setController(NewWindowController);
*/
Scene scene = new Scene(fxmlLoader.load(), 600, 400);
Stage stage = new Stage();
stage.setTitle("New Window");
stage.setScene(scene);
stage.show();
} catch (IOException e) {
Logger logger = Logger.getLogger(getClass().getName());
logger.log(Level.SEVERE, "Failed to create new Window.", e);
}
});
The code below worked for me I used part of the code above inside the button class.
public Button signupB;
public void handleButtonClick (){
try {
FXMLLoader fxmlLoader = new FXMLLoader();
fxmlLoader.setLocation(getClass().getResource("sceneNotAvailable.fxml"));
/*
* if "fx:controller" is not set in fxml
* fxmlLoader.setController(NewWindowController);
*/
Scene scene = new Scene(fxmlLoader.load(), 630, 400);
Stage stage = new Stage();
stage.setTitle("New Window");
stage.setScene(scene);
stage.show();
} catch (IOException e) {
Logger logger = Logger.getLogger(getClass().getName());
logger.log(Level.SEVERE, "Failed to create new Window.", e);
}
}
}
I have a method which performs some task(reading, writing files and other tasks also) for almost 3 minutes.
I want to bind progress bar in javafx which can run with progress of the method.
This is my method
System.out.println("Going to load contract/security:"+new Date());
Map<Integer,FeedRefData> map = loadContractAndSecurityFromFile(loadFO);
addIndicesRefData(map);
BufferedWriter writer = createFile();
for (FeedRefData feedRefData : map.values()) {
try {
updateInstrumentAlias(map, feedRefData);
String refDataString = feedRefData.toString();
writer.write(refDataString, 0, refDataString.length());
writer.newLine();
writer.flush();
} catch (IOException e) {
e.printStackTrace();
log.info("Unable to write Quote Object to : " );
}
}
System.out.println("Ref Data File Generated:"+new Date());
For bind your method with progressbar you should do these steps :
Create a task which contains your method.
Create a thread which run this task.
Bind your progress property with your task property.
I made this simple example ,just change my code with your method code :
public class Bind extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) {
ProgressBar pb = new ProgressBar();
pb.setProgress(1.0);
Button button = new Button("start");
button.setOnAction((ActionEvent event) -> {
/*Create a task which contain method code*/
Task<Void> task = new Task<Void>() {
#Override
protected Void call() throws Exception {
File file = new File("C:\\Users\\Electron\\Desktop\\387303_254196324635587_907962025_n.jpg");
ByteArrayOutputStream bos = null;
try {
FileInputStream fis = new FileInputStream(file);
byte[] buffer = new byte[1024];
bos = new ByteArrayOutputStream();
for (int len; (len = fis.read(buffer)) != -1;) {
bos.write(buffer, 0, len);
updateProgress(len, file.length());
/* I sleeped operation because reading operation is quiqly*/
Thread.sleep(1000);
}
System.out.println("Reading is finished");
} catch (FileNotFoundException e) {
System.err.println(e.getMessage());
} catch (IOException e2) {
System.err.println(e2.getMessage());
}
return null;
}
};
Thread thread = new Thread(task);
thread.start();
/*bind the progress with task*/
pb.progressProperty()
.bind(task.progressProperty());
});
HBox box = new HBox(pb, button);
Stage stage = new Stage();
StackPane root = new StackPane();
root.getChildren().add(box);
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
}
Operation started :
Operation finished :
PS: I used Thread.sleep(1000) because my file is so small.You can remove it if your progress time is long.
i am having a problem when i click on the button it doesn t work.
actually for the moment i am just asking that the button execute a system.out.println() just for the test. the name of the button is btndetailUser
listRechercheUser.setCellFactory(new Callback<ListView<User>, ListCell<User>>() {
#Override
public ListCell<User> call(ListView<User> p) {
ListCell<User> cell;
cell = new ListCell<User>() {
#Override
protected void updateItem(User user, boolean bln) {
super.updateItem(user, bln);
if (user != null) {
ImageView img;
String mm=user.getPath().trim();
if (mm.equals("fusee.png")){
img = new ImageView(new Image("mto/cr/images/"+mm));}
else{
img = new ImageView(new Image("mto/cr/images/mains-fonds.png"));
}
VBox vb = new VBox(10);
HBox hb = new HBox(20);
VBox vb1 = new VBox(20);
VBox vb3= new VBox(20);
vb1.getChildren().add(new Label(" "));
hb.setStyle("-fx-border-color: #C8C8C8 ;");
vb.setAlignment(Pos.CENTER);
VBox vb2 = new VBox(30);
vb.setAlignment(Pos.CENTER);
vb2.setAlignment(Pos.BASELINE_LEFT);
vb3.setAlignment(Pos.CENTER_RIGHT);
Label id = new Label(user.getId()+"id firas:");
Label username = new Label(user.getUsername()+" username firas:");
Label nom = new Label(user.getNom()+"nom firas:");
Label prenom = new Label(user.getPrenom()+"prenom firas:");
Button btndetailUser = new Button();
btndetailUser.setId("btndetailUser");
btndetailUser.setText("btndetailUser "+user.getId());
Image imageAccesProjet = new Image("mto/cr/images/enter.png");
ImageView enterIV= new ImageView(imageAccesProjet);
enterIV.setFitHeight(10);
enterIV.setFitWidth(10);
btndetailUser.setGraphic(enterIV);
btndetailUser.getStyleClass().add("buttonLogin");
System.out.println(btndetailUser.getText());
btndetailUser.setOnMouseClicked(
(MouseEvent event2) ->
System.out.println("firas"));
btndetailUser.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
System.out.println(".handle()");
}
});
vb.getChildren().addAll(new Label(" "), img, new Label(" "),username);
vb2.getChildren().addAll(nom, prenom);
vb3.getChildren().addAll(btndetailUser);
hb.getChildren().addAll(vb1, vb, vb2,vb3);
setGraphic(hb);
}
}
};
return cell;
}
});
try something like,
btndetailUser.setOnAction(e -> {
System.out.println("freetext")
});
Im developing one app, In that app, Im sharing image in social networks(Converting the layout into image) so my question is in my layout am having share icon, so i want remove that share icon and add textview to that layout before converting into image. can anyone give solution for my question. Thanks in advance

I can add SplitPane in a XYChart by clicking the "Add Pane" button, and it works fine.
Now I would like to remove SplitPane by clicking the "Remove pane" button.
Here is full code
public class SplitPaneFxTest extends Application {
SplitPane splitPane = new SplitPane();
double percSplit = 0.50;
int idxSplit = 0;
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
launch(SplitPaneFxTest.class, args);
}
#Override
public void start(Stage primaryStage) {
primaryStage.setTitle("SplitPane Test");
Group root = new Group();
Scene scene = new Scene(root, 800, 650, Color.WHITE);
//CREATE THE SPLITPANE
splitPane.setPrefSize(scene.getWidth(), scene.getHeight());
splitPane.setOrientation(Orientation.VERTICAL);
//ADD LAYOUTS AND ASSIGN CONTAINED CONTROLS
BorderPane upperPane = new BorderPane();
HBox hbox = new HBox();
Button button1 = new Button("Add Pane");
hbox.getChildren().addAll(button1);
upperPane.setTop(hbox);
Button button2 = new Button("Remove Pane");
hbox.getChildren().addAll(button2);
upperPane.setTop(hbox);
BorderPane lowerPane = new BorderPane();
splitPane.getItems().addAll(upperPane);
splitPane.setDividerPosition(idxSplit, 0.70);
idxSplit++;
splitPane.getItems().addAll(lowerPane);
idxSplit++;
root.getChildren().add(splitPane);
primaryStage.setScene(scene);
primaryStage.show();
button1.setOnAction(new EventHandler<ActionEvent>() {
#Override public void handle(ActionEvent e) {
BorderPane myborderpane = new BorderPane();
splitPane.getItems().addAll(myborderpane);
ObservableList<SplitPane.Divider> splitDiv = splitPane.getDividers();
System.out.println("splitDiv.size() "+splitDiv.size());
percSplit = 1/(double)(splitDiv.size()+1);
for (int i = 0; i< splitDiv.size(); i++) {
System.out.println("i "+i+" percSplit "+percSplit);
splitPane.setDividerPosition(i, percSplit);
percSplit += 1/(double)(splitDiv.size()+1);
}
}
});
}
}
Any help really appreciated.
You can store a list of inner panes and remove them based on this list:
final List<Pane> panes = new ArrayList<Pane>();
button1.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent e) {
BorderPane myborderpane = new BorderPane();
//adding
panes.add(myborderpane);
splitPane.getItems().addAll(myborderpane);
ObservableList<SplitPane.Divider> splitDiv = splitPane.getDividers();
System.out.println("splitDiv.size() " + splitDiv.size());
percSplit = 1 / (double) (splitDiv.size() + 1);
for (int i = 0; i < splitDiv.size(); i++) {
System.out.println("i " + i + " percSplit " + percSplit);
splitPane.setDividerPosition(i, percSplit);
percSplit += 1 / (double) (splitDiv.size() + 1);
}
}
});
button2.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent t) {
if (panes.size() > 0) {
// removing from both list and splitPane childs
Pane toDelete = panes.remove(0);
splitPane.getItems().remove(toDelete);
}
}
});
Also you can remove panes directly from ScrollPane.getChildren() but it can involve tricky and unreliable code to determine which pane to remove.
