Mastering JavaFX 10

Managing ListView items

The ListView content is backed up by an ObservableList and any changes to this list are automatically reflected in the ListView, as in the button handler in the next example:

// chaptep10/list/ListViewDemo.javaObservableList<String> items = FXCollections.observableArrayList(        "Red", "Blue", "Yellow", "Green");ListView<String> list = new ListView<>(items);Button btn = new Button("Add New Item");btn.setOnAction((e) -> {    items.add(            // just a way to generate semirandom new items            items.get(new Random().nextInt(items.size()))    );});
