MouseListener on editable JavaFX ComboBox - combobox

MouseEvent is not working for JavaFX ComboBox when it is set to editable. It is working well on Non editable ComboBox. Is there any way to set MouseEvent on editable ComboBox?
package editablecombobox;
import javafx.application.Application;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.ComboBox;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class EditableComboBox extends Application {
#Override
public void start(Stage primaryStage) {
ComboBox combo = new ComboBox();
combo.setEditable(true);
combo.setOnMousePressed(new EventHandler<MouseEvent>() { //adding MouseEvent on ComboBox
#Override
public void handle(MouseEvent event) {
System.out.println("MOUSE PRESSED!!!");
}
});
StackPane root = new StackPane();
root.getChildren().add(combo);
Scene scene = new Scene(root, 300, 250);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
setOnMousePressed is not working.

I guess you are just interested in the Editable TextField area of the ComboBox. You need to add the MouseListener to the editor(TextField) of the ComboBox. Try using :
combo.getEditor().setOnMousePressed(new EventHandler<MouseEvent>() {
#Override
public void handle(MouseEvent event) {
System.out.println("MOUSE PRESSED!!!");
}
});

Remove item from a RecyclerView list based on status of a checkbox

I have a list application what is uses RecyclerView.
Each line has got a button, a checkbox and 2 textview.
All object is defined the RecyclerView clas, but I would like to check the checkbox status in the Main class and evaluate the status and remove the item from the list and from the SharedPreferences where the checkbox is checked
Main class is here:
package com.example.homehandling;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.TextView;
import android.widget.Toast;
import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.LinearLayoutManager;
import androidx.recyclerview.widget.RecyclerView;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Date;
import java.util.LinkedList;
import java.util.List;
import java.util.Locale;
import java.util.Map;
public class ToDoList extends AppCompatActivity implements MyRecyclerViewAdapter.ItemClickListener, View.OnClickListener {
public MyRecyclerViewAdapter adapter;
public Button btn;
public SharedPreferences sharedPreferences;
public SharedPreferences.Editor myEdit;
public LinkedList<String> items, remain_days, prio;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_shoppinglist);
sharedPreferences = getSharedPreferences("ToDoList", Context.MODE_PRIVATE);
myEdit = sharedPreferences.edit();
btn = findViewById(R.id.button);
items = new LinkedList<>();
remain_days = new LinkedList<>();
prio = new LinkedList<>();
RecyclerView recyclerView = findViewById(R.id.list);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
adapter = new MyRecyclerViewAdapter(this,items,remain_days,prio);
adapter.setClickListener(this);
recyclerView.setAdapter(adapter);
btn.setOnClickListener(this);
StartDisplay();
}
#Override
public void onItemClick(View view, int position) {
}
#Override
public void onClick(View v) {
Intent NewTLItem = new Intent(ToDoList.this, NewTLItem.class);
startActivity(NewTLItem);
}
#Override
public void onResume() {
super.onResume();
StartDisplay();
}
public void StartDisplay()
{
sharedPreferences = getSharedPreferences("ToDoList", Context.MODE_PRIVATE);
Map<String, ?> allEntries = sharedPreferences.getAll();
items.clear();
prio.clear();
remain_days.clear();
for (Map.Entry<String, ?> entry : allEntries.entrySet())
{
String key_word = entry.getKey();
String [] item_total = entry.getValue().toString().split(";");
if(key_word.contains("_")) key_word = key_word.replace("_"," ");
items.add(key_word);
remain_days.add(Long.toString(DateCalc(item_total[0])));
prio.add(item_total[1]);
}
adapter.notifyDataSetChanged();
}
public long DateCalc(String startdate)
{
Date system_date, due_date;
long diff_date = 0;
String currentDate = new SimpleDateFormat("dd-MM-yyyy", Locale.getDefault()).format(new Date());
SimpleDateFormat dates = new SimpleDateFormat("dd-MM-yyyy");
try {
system_date = dates.parse(currentDate);
due_date = dates.parse(startdate);
diff_date = (due_date.getTime()-system_date.getTime())/86400000;
} catch (ParseException e) {
e.printStackTrace();
}
return diff_date;
}
}
At now the item is removed when the whole line is touched. I would like to exchange to if only the Checkbox is "true".
At now the remove method is in the public void onItemClick(View view, int position) function.
I would like to put the content of the OnItemClick method to "if" part of CheckBox status.
Here is the RecyclerView class:
package com.example.homehandling;
import android.content.Context;
import android.content.Intent;
import android.graphics.Color;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.TextView;
import android.widget.Toast;
import androidx.recyclerview.widget.RecyclerView;
import java.util.List;
public class MyRecyclerViewAdapter extends RecyclerView.Adapter<MyRecyclerViewAdapter.ViewHolder>
{
public List<String> mData, subdata, subdata2;
public LayoutInflater mInflater;
public ItemClickListener mClickListener;
public Context context;
public CheckBox done;
MyRecyclerViewAdapter(Context context, List<String> data, List<String> subdata, List<String> subdata2) {
this.mInflater = LayoutInflater.from(context);
this.mData = data;
this.subdata = subdata;
this.subdata2 = subdata2;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = mInflater.inflate(R.layout.recyclerview_row, parent, false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
String meta_data = mData.get(position);
String meta_subdata = subdata.get(position);
String meta_subdata2 = subdata2.get(position);
holder.myTextView.setText(meta_data);
holder.subtext.setText(meta_subdata +" "+ meta_subdata2);
holder.add.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String[] item_param = holder.myTextView.getText().toString().split(" ");
final Intent intent;
intent = new Intent(context, NewSLItem.class);
intent.putExtra("param",item_param[0]);
context.startActivity(intent);
}
});
}
#Override
public int getItemCount() {
return mData.size();
}
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener
{
public TextView myTextView, subtext;
public Button add;
public ViewHolder(View itemView)
{
super(itemView);
context = itemView.getContext();
myTextView = itemView.findViewById(R.id.tvAnimalName);
subtext = itemView.findViewById(R.id.subtext);
add = itemView.findViewById(R.id.add);
done = itemView.findViewById(R.id.done);
itemView.setOnClickListener(this);
}
#Override
public void onClick(View view)
{
if (mClickListener != null) mClickListener.onItemClick(view, getAdapterPosition());
}
}
String getItem(int id) {return mData.get(id);
}
void setClickListener(ItemClickListener itemClickListener) {
this.mClickListener = itemClickListener;
}
public interface ItemClickListener
{
void onItemClick(View view, int position);
}
}
if(adapter.done.isChecked())should work I think, but I got null opbject reference exception.
Maybe the problem is that the checkbox is in the RecyclerView layout and not in Main class layout, but I am not sure.
Is it possible to handle the Checkbox methods from other class, and if yes, then where should I improve the code?

How to save entire object for a checkbox in javafx

I have number of objects. Let's say i have 10 Books object and i want user to select any number of the book. When user press the submit button i want to retrieve all the books "object" that user selected.
As of now, while showing screen to user i use
CheckBox cb= new CheckBox(book.getName());
this shows bookname to user and user selects the book. But on runtime i will be needing bookid and other properties of book object as well.
Is there anyway through which i can save the book object in the checkbox?
Basic Examle. if you want more sepecifc you need to post your code, we can set object to node using setUserDate, then we can use that object when we need. here i am using object id for example, in yor case save that object i hope this will solve your problem ,?s post a comment

Consider using a control with built-in selection functionality, such as a ListView. Then you can just check the selection model.
import java.util.stream.IntStream;
import javafx.application.Application;

import javafx.stage.Stage;
public class BookSelection extends Application {
#Override
public void start(Stage primaryStage) {
ListView<Book> bookList = new ListView<>();
bookList.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);
bookList.setCellFactory(lv -> new ListCell<Book>() {
#Override
public void updateItem(Book book, boolean empty) {
super.updateItem(book, empty);
if (empty) {
setText(null);
} else {
setText(book.getTitle());
}
}
});
IntStream.rangeClosed(1, 10).mapToObj(i -> new Book("Book "+i)).forEach(bookList.getItems()::add);
Button submit = new Button("Submit selection");
submit.setOnAction(e ->
bookList.getSelectionModel().getSelectedItems().forEach(book -> System.out.println(book.getTitle())));
BorderPane root = new BorderPane(bookList, null, null, submit, null);
BorderPane.setAlignment(submit, Pos.CENTER);
BorderPane.setMargin(submit, new Insets(10));
Scene scene = new Scene(root, 600, 600);
primaryStage.setScene(scene);
primaryStage.show();
}
public static class Book {
private final StringProperty title = new SimpleStringProperty() ;

}
public final StringProperty titleProperty() {
return this.title;

If for some reason you really want to implement this with check boxes, you can keep a Set<Book> representing the selected books, and update it when each check box is selected/unselected. Note this is similar to #user99370's answer, but is more robust as it avoids downcasting the (essentially unknown-type) userData to your data type.

grid.setHgap(5);
grid.setVgap(5);
grid.setPadding(new Insets(10 ));
List<Book> books = IntStream.rangeClosed(1, 10).mapToObj(i -> new Book("Book "+i)).collect(Collectors.toList());
Set<Book> selectedBooks = new HashSet<>();
int row = 0 ;
for (Book book : books) {
CheckBox checkBox = new CheckBox();
checkBox.selectedProperty().addListener((obs, wasSelected, isNowSelected) -> {
if (isNowSelected) {
selectedBooks.add(book);
} else {
selectedBooks.remove(book);
}
});
grid.addRow(row, checkBox, new Label(book.getTitle()));
row++ ;
}
Button submit = new Button("Submit selection");
submit.setOnAction(e ->
selectedBooks.forEach(book -> System.out.println(book.getTitle())));
GridPane.setHalignment(submit, HPos.CENTER);
grid.add(submit, 0, row, 2, 1);
Scene scene = new Scene(grid, 600, 600);
primaryStage.setScene(scene);
primaryStage.show();
}
public static class Book {
private final StringProperty title = new SimpleStringProperty() ;
public Book(String title) {
setTitle(title);
}
public final StringProperty titleProperty() {
return this.title;
}
public final java.lang.String getTitle() {
return this.titleProperty().get();

public final void setTitle(final java.lang.String title) {
this.titleProperty().set(title);
}
}
public static void main(String[] args) {

This is just a simplified version of the accepted answer.
We can use setUserData(Object) to set data and getUserData() to retrieve the previously set data of any JavaFX node (including CheckBox).

Different events for CheckBox's box and label?(JavaFX)

I want my CheckBox to become selected only when box is clicked. If CheckBox's label is clicked I want to perform different action with this CheckBox being not selected. How is it possible to achieve this?
I made separate checkbox and label. But I can't change label's pseudo class through checkbox. They are al in listview. Here is a part of the code:
HBox todoHBox=new HBox(0);
CheckBox todoCheckBox=new CheckBox();
Label todoLabel=new Label(item.getName());
Label timeLabel=new Label();
Region rSpring = new Region();
todoHBox.setPrefWidth(300);
todoHBox.setHgrow(rSpring, Priority.ALWAYS);
todoHBox.setHgrow(timeLabel, Priority.ALWAYS);
todoHBox.setHgrow(todoCheckBox, Priority.NEVER);
timeLabel.setMinWidth(60);
timeLabel.getStyleClass().add("time-label");
todoLabel.getStyleClass().add("todo-label");
todoHBox.getChildren().addAll(todoCheckBox,todoLabel,rSpring,timeLabel);
todoHBox.setMargin(timeLabel, new Insets(3,0,0,0));
PseudoClass pseudo = PseudoClass.getPseudoClass("task-done");
todoCheckBox.selectedProperty().addListener(e->{
if(todoCheckBox.isSelected()){
todoLabel.pseudoClassStateChanged(pseudo, true);
}else{
todoLabel.pseudoClassStateChanged(pseudo, false);
}});
setGraphic(todoHBox);
Just use two controls: a CheckBox with no text and a Label. Call setOnMouseClicked(...) on the Label with a handler that does whatever you need.
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.CheckBox;
import javafx.scene.control.Label;
import javafx.scene.layout.HBox;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class CheckBoxWithLabelExample extends Application {
#Override
public void start(Stage primaryStage) {
CheckBox checkBox = new CheckBox();
checkBox.selectedProperty().addListener((obs, wasSelected, isNowSelected) ->
System.out.println("Check box is now "+(wasSelected ? "not ":"") + "selected"));
Label label = new Label("Make Task");
label.setOnMouseClicked(e -> System.out.println("Text clicked"));
HBox control = new HBox(checkBox, label);
Scene scene = new Scene(new StackPane(control), 350, 75);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}

Combobox refresh value and listview when object content change

I would like to update my combobox when the content of the object used to display text in combo changes.
Here is a sample:
package com.javafx.example.combobox;
import javafx.application.Application;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
import javafx.collections.FXCollections;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.ComboBox;
import javafx.scene.control.TextField;
import javafx.scene.layout.HBox;
import javafx.scene.layout.Priority;
import javafx.stage.Stage;
import javafx.util.StringConverter;
public class ComboboxSample extends Application {
class Sequence {
public StringProperty name = new SimpleStringProperty();
public Sequence(String name) {
super();
this.name.set(name);
}
#Override
public String toString() {
return "null";
}
}
#Override
public void start(Stage stage) throws Exception {
stage.setTitle("ComboBoxSample");
ComboBox<Sequence> combo = new ComboBox<>();
combo.setItems(FXCollections.observableArrayList(
new Sequence("Toto"),
new Sequence("Titi")));
combo.getSelectionModel().selectFirst();
combo.setConverter(new StringConverter<ComboboxSample.Sequence>() {
#Override
public String toString(Sequence sequence) {
return sequence.name.get();
}
#Override
public Sequence fromString(String string) {
System.out.println("call fromString");
return null;
}
});
TextField text = new TextField();
Button renameButton = new Button("Rename");
renameButton.setOnAction(evt -> combo.getValue().name.set(text.getText()));
HBox root = new HBox(combo, text, renameButton);
HBox.setHgrow(text, Priority.ALWAYS);
stage.setScene(new Scene(root));
stage.show();
}
public static void main(String... args) {
launch(args);
}
}
The combobox contains objects with a property name. If i rename this property, the display do not change or sometimes it changes but not all the time. It is the standard behavior as the combobox update when the object changes, and not when its content changes.
How can i do to force the combobox to refresh its value and the listview on change?
Thanks
EDIT1:
Using a callback in an observaleList seems to be a solution.

}
}
#Override

stage.setTitle("ComboBoxSample");
Callback<Sequence, Observable[]> extractor = new Callback<Sequence, Observable[]>() {
#Override

return new Observable[] {s.name};
}
};
sequences = FXCollections.observableArrayList(extractor);
sequences.addAll(
new Sequence("Toto"),
new Sequence("Titi"));
ComboBox<Sequence> combo = new ComboBox<>();
combo.setItems(sequences);
combo.getSelectionModel().selectFirst();
combo.setConverter(new StringConverter<ComboboxSample.Sequence>() {
#Override
public String toString(Sequence sequence) {
return sequence.name.get();
}
#Override
public Sequence fromString(String string) {
System.out.println("call fromString");
return null;
}
});
combo.valueProperty().addListener((obs, oldValue, newValue) -> System.out.println("Change from " + oldValue.name.get() + " to " + newValue.name.get()));
TextField text = new TextField();
Button renameButton = new Button("Rename");
renameButton.setOnAction(evt -> {
combo.getValue().name.set(text.getText());
});
HBox root = new HBox(combo, text, renameButton);

Everytime a new value is added to the object list, set the combobox value again. Works for me. I did a small example to show this. Hope it is helpful

JAVAFX editable ComboBox: refresh after changing a value

I'm still new to JavaFX and need to create a combobox with objects (SimlpePerson) and not strings. I want to edit the shown value in the box itself. Works good for strings but I have problems with SimpleObjects. I made a StringConverter and it also works, I can edit the object shown in the comboBox. But the list itself is not rerendered after that. If I click on the ComboBox I see the original values. How can I change that?
Any suggestion is very welcome!=)
BR and Thank you!

Check out this solution. There is a handler which is triggered when you've finished editing. There you may implement all the code which changes the model's state.
To update the combobox list the following approach work may:
cb.getEditor().setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent actionEvent) {
SimplePerson person = cb.getValue();
if (null != person) {
int idx = persons.indexOf(person);
person.setName(cb.getEditor().getText());
persons.set(idx, person);
cb.setValue(person);
}
}
});
