First, you’ll have to create this class in your project: import javafx.collections.FXCollections; import javafx.collections.ObservableList; import javafx.event.EventHandler; import javafx.scene.control.ComboBox; import javafx.scene.input.KeyCode; import javafx.scene.input.KeyEvent; public class FxUtilTest { public interface AutoCompleteComparator<T> { boolean matches(String typedText, T objectToCompare); } public static<T> void autoCompleteComboBoxPlus(ComboBox<T> comboBox, AutoCompleteComparator<T> comparatorMethod) { ObservableList<T> data = comboBox.getItems(); comboBox.setEditable(true); comboBox.getEditor().focusedProperty().addListener(observable -> { if (comboBox.getSelectionModel().getSelectedIndex() < … Read more
