observablelist

The JavaDoc for the ListChangeListener provides a template for handling changes. I don't know how to handle permutations, however. For every index, I can find out where the new index of the item is, but I don't know what to do with it. This is a bit of a puzzle that is independent of programming language. An ObservableList can only add(), remove(), set(), and also has an iterator. If I have an original list [1,2,3], and bind a list[] to it, the bound list[1,2,3] needs to match it. If the original list gets its comparator swapped so that the original list now reads [3,2,1], how do I make the

I have a MasterData which is an ObservableList and filteredData which is also an ObservableList. Then, I want to use it to show the filtered data when the filter is set , but also to be able to recover whenever necessary , here is the MCVE: package br; import javafx.collections.FXCollections; import javafx.collections.ObservableList; public class Main{ private static ObservableList<Foo> masterData = FXCollections.observableArrayList(); private static ObservableList<Foo> filteredData = FXCollections.observableArrayList(); static Filter filter = new Filter(); public static void addDummy(){

Say I have a JavaFX app with an observable class SomeObservableClass with some Properties: public class SomeObservableClass{ private StringProperty prop1 = new SimpleStringProperty(); private DoubleProperty prop2 = new SimpleDoubleProperty(); ... constructors, getters and setters } and another class which has a property: public class ParentClass{ private ObservableList<SomeObservableClass> sOC = FXCollections.observableArrayList();` } In this parent class I add a listener for the observable list: ` public class ParentClass{ private ObservableList<SomeObservableClass> observableList =

I cant seem to find a solution for this and new to java/ javafx: I have a 3 column tableview , last column is a price column. I would like to display a running total of the price column whenever a row is added or deleted from the tableview. TableView is populated from an ObservableList which holds a 3 field object per row. String id,String product, Double price.........it is the price I would like to keep a running total of in a separate textField Since the items of tableview are ObservableList, you may track for ListChangeListener, and update the calculated total price: public class Sample

I have no problem filling my tableview with diffrent data from 1 class. But it does not work for me with multiple classes. Any idea how to solve that? I have checked out similar questions on stackoverflow. But none of them could help me. If you suggest anything with the "Callback" class, please provide me the full import, because there are a couple of Callback classes out there. public class MainViewController implements Initializable { @FXML private TableColumn<TaskControl, Boolean> colErledigt; @FXML private TableColumn<TaskControl, Character> colPrioritaet; @FXML private TableColumn
