because I don't really know the sollution. Lets say i have a TableView that holds info about product: description, quantity and the price. Also have a label that shows a sum of prices (times quantity) of all products from a table. Now i want to be notified about any changes that took affect on this component like changes in existing rows or addition of a new one. Is there any listener or sth similar to achieve it?

To select a row with a specific index you can use the select(int) method. Here is an example of selecting a single row with a given index in a JavaFX TableView: selectionModel. select(1);
We can filter TableView content in two main ways – manually, or by using the FilteredList class JavaFX provides. In either case, we can update our search criteria by placing a ChangeListener on the search box TextField. This way, each time the user changes their search, the TableView is updated automatically.
The TableView class provides built-in capabilities to sort data in columns. Users can alter the order of data by clicking column headers. The first click enables the ascending sorting order, the second click enables descending sorting order, and the third click disables sorting. By default, no sorting is applied.
Usually you construct a TableView by passing an ObservableList to it. Something like this: TableView myTable = new TableView<>(myObservableList);
ObservableList<ClassOfTheObjectsInTheList> myObservableList = FXCollections.FXCollections.observableArrayList(anyNoneObservableCollection);
TableView<ClassOfTheObjectsInTheList> myTable = new TableView<>(myObservableList);
You can add a ListChangeListener to any ObservableList at will by doing:
myObservableList.addListener(new ListChangeListener<ClassOfObjectsInTheList>(){
@Override
public void onChanged(javafx.collections.ListChangeListener.Change<? extends ClassOfObjectsInTheList> pChange) {
while(pChange.next()) {
// Do your changes here
}
}
});
