JavaFX and JPA 2.0 with my custom component

In this third and last part, we are going to create a small application which dynamically updates the results in the result list when the user types the search word(s) in a text box.
To do that we will re-use the table and the entity created in the part one, the java class created in the part two and my search text box that I've created some time ago (with a small correction).

package javafxjpa2searchtextbox;

import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.text.Text;
import javafx.scene.text.Font;
import customcomponent.SearchTextBox;
import javafx.scene.control.ListView;
import paddy.domain.Music;
import paddy.service.MusicServices;

var listMusic;

var seqMusic:Music[];

var musicServices:MusicServices = MusicServices{};

Stage {
    title: "Application title"
    width: 600
    height: 250
    scene: Scene {
        stylesheets : ["{__DIR__}resources/mac.css"]
        content: [
            Text {
                font: Font {
                    size: 16
                x: 10
                y: 30
                content: "Search DB"
            SearchTextBox {
                translateX: 10
                translateY: 40
                onResetSearch: function () {
                    println("reset !");
                        delete seqMusic;
                onSearch: function (s: String) {
                    println("Search of : {s}");

                    listMusic = musicServices.getArtisteNameBeginingBy(s);
                    delete seqMusic;
                    seqMusic = listMusic.toArray(seqMusic);

            ListView {
                layoutY: 75
                width: 575
                height: 100
                items: bind seqMusic

The key points:
  • Delete the sequence on the onResetSearch event of the SearchTextBox component
    delete seqMusic;
  • Call the getArtisteNameBeginningBy method, delete the sequence and refill it on the onSearch event  of the SearchTextBox component
    listMusic = musicServices.getArtisteNameBeginningBy(s);
    delete seqMusic;
    seqMusic = listMusic.toArray(seqMusic);

Get the NetBeans project           
Note: don’t forget to create (in NetBeans) a library containing the jar DerbyClient.jar and being called DerbyClient.
