====== Correction TP4 ======


===== MVC =====

Seuls UserInterface et Controller ont changé. On a mis en place des getter dans UserInterface et ont les a utilisés dans le contrôleur.

=== UserInterface.java ===

<code java>
package com.mco;

import javafx.scene.Group;
import javafx.scene.control.Button;
import javafx.scene.control.TextField;
import javafx.scene.layout.HBox;
import javafx.scene.text.Text;

public class UserInterface {
    private Group root;

    private TextField todoItemInput;
    private Button addButton;

    public UserInterface() {
        root = generateUI();
    }

    private Group generateUI() {
        Group uiRoot = new Group();

        HBox hBox = new HBox(10);
        uiRoot.getChildren().add(hBox);

        Text text = new Text("Input:");
        todoItemInput = new TextField();
        addButton = new Button("add");

        hBox.getChildren().addAll(text, todoItemInput, addButton);

        return uiRoot;
    }

    public Group getRoot() {
        return root;
    }

    public TextField getTodoItemInput() {
        return todoItemInput;
    }

    public Button getAddButton() {
        return addButton;
    }
}

</code> 


=== Controller.java === 

<code java>
package com.mco;

import javafx.event.ActionEvent;
import javafx.scene.control.Button;

import java.util.ArrayList;

public class Controller {
    private ArrayList<String> model;
    private UserInterface vue;

    public Controller(ArrayList<String> model, UserInterface vue) {
        this.model = model;
        this.vue = vue;

        Button button = vue.getAddButton();

        button.setOnAction(this::handleButtonAdd);
    }

    private void handleButtonAdd(ActionEvent actionEvent) {
        String todoItemText = vue.getTodoItemInput().getText();
        if (!todoItemText.equals("")) {
            model.add(todoItemText);
        }
        
        System.out.println(model);
    }
}
</code>


===== Amélioration de UI =====

Javafx 8 permet de faire de nombreux agencements de composants graphique, lisez par exemple ce [[http://docs.oracle.com/javase/8/javafx/layout-tutorial/builtin_layouts.htm|tutorial sur les layouts]].

==== Représentez le modèle ==== 

On a ajouté un champ contenant notre liste dans la vue et on l'a utilisé dans le contrôleur.

=== UserInterface.java ===

<code java>
package com.mco;

import javafx.scene.Group;
import javafx.scene.control.Button;
import javafx.scene.control.ScrollPane;
import javafx.scene.control.TextField;
import javafx.scene.layout.HBox;
import javafx.scene.layout.VBox;
import javafx.scene.text.Text;

public class UserInterface {
    private Group root;

    private TextField todoItemInput;
    private Button addButton;
    private VBox todoItemList;

    public UserInterface() {
        root = generateUI();
    }

    private Group generateUI() {
        Group uiRoot = new Group();

        HBox hBox = new HBox(10);


        Text text = new Text("Input:");
        todoItemInput = new TextField();
        addButton = new Button("add");

        hBox.getChildren().addAll(text, todoItemInput, addButton);

        VBox vBox = new VBox(20);

        todoItemList = new VBox(5);
        ScrollPane scrollPane = new ScrollPane();
        scrollPane.setContent(todoItemList);
        scrollPane.setPrefSize(200, 200);

        vBox.getChildren().add(hBox);
        vBox.getChildren().add(scrollPane);

        uiRoot.getChildren().add(vBox);

        return uiRoot;
    }

    public Group getRoot() {
        return root;
    }

    public TextField getTodoItemInput() {
        return todoItemInput;
    }

    public Button getAddButton() {
        return addButton;
    }

    public VBox getTodoItemList() {
        return todoItemList;
    }
}

</code>

=== Controller.java ===

<code java>
package com.mco;

import javafx.event.ActionEvent;
import javafx.scene.control.Button;
import javafx.scene.text.Text;

import java.util.ArrayList;

public class Controller {
    private ArrayList<String> model;
    private UserInterface vue;

    public Controller(ArrayList<String> model, UserInterface vue) {
        this.model = model;
        this.vue = vue;

        Button button = vue.getAddButton();

        button.setOnAction(this::handleButtonAdd);
    }

    private void handleButtonAdd(ActionEvent actionEvent) {
        String todoItemText = vue.getTodoItemInput().getText();
        if (!todoItemText.equals("")) {
