javaFX中对ListView Tree Table的操作

今天研究FX中插入数据

先贴一段官方的ListView插入数据的方法

<p>/* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */package swinginterop;</p><p>import javafx.application.Application;import javafx.collections.FXCollections;import javafx.collections.ObservableList;import javafx.scene.Scene;import javafx.scene.control.*;import javafx.scene.control.cell.ComboBoxListCell;import javafx.scene.layout.StackPane;import javafx.stage.Stage;</p><p>public class ListViewSample extends Application {</p><p>    public static final ObservableList data            = FXCollections.observableArrayList();</p><p>    public static void main(String[] args) {        launch(args);    }</p><p>    @Override    public void start(Stage primaryStage) {        primaryStage.setTitle("List View Sample");</p><p>        final ListView listView = new ListView(data);        listView.setPrefSize(200, 250);        listView.setEditable(true);</p><p>        for (int i = 0; i < 18; i++) {            data.add("anonym");        }</p><p>        listView.setItems(data);</p><p>        StackPane root = new StackPane();        root.getChildren().add(listView);        primaryStage.setScene(new Scene(root, 200, 250));        primaryStage.show();    }}</p>

通过FXCollection创建了一个名字的Arraylist 然后将数据插入以后放入了List，可是研究过Table以后发现了FX 给我们提供了比较强大的数据对象支持。

稍微改一下添加一个数据对象，照抄Table的例子，拿出Person对象放入类里，然后再添加一个toString方法让他显示名字

如下代码：

/* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */package swinginterop;import javafx.application.Application;import javafx.beans.property.BooleanProperty;import javafx.beans.property.SimpleBooleanProperty;import javafx.beans.property.SimpleStringProperty;import javafx.beans.property.StringProperty;import javafx.beans.value.ChangeListener;import javafx.beans.value.ObservableValue;import javafx.collections.FXCollections;import javafx.collections.ObservableList;import javafx.scene.Scene;import javafx.scene.control.*;import javafx.scene.control.cell.ComboBoxListCell;import javafx.scene.layout.StackPane;import javafx.stage.Stage;public class ListViewSample extends Application {    public static final ObservableList data            = FXCollections.observableArrayList();    public static void main(String[] args) {        launch(args);    }    @Override    public void start(Stage primaryStage) {        primaryStage.setTitle("List View Sample");        final ListView listView = new ListView(data);        listView.setPrefSize(200, 250);        listView.setEditable(true);        for (int i = 0; i < 18; i++) {            data.add(new Person("firstName" + i, "lastName" + i, "email" + i));        }        listView.setItems(data);        StackPane root = new StackPane();        root.getChildren().add(listView);        primaryStage.setScene(new Scene(root, 200, 250));        primaryStage.show();    }    public static class Person {        private StringProperty firstName;        private StringProperty lastName;        private StringProperty email;        private Person(String fName, String lName, String email) {            this.firstName = new SimpleStringProperty(fName);            this.lastName = new SimpleStringProperty(lName);            this.email = new SimpleStringProperty(email);        }        public StringProperty firstNameProperty() {            return firstName;        }        public StringProperty lastNameProperty() {            return lastName;        }        public StringProperty emailProperty() {            return email;        }        public void setLastName(String lastName) {            this.lastName.set(lastName);        }        public void setFirstName(String firstName) {            this.firstName.set(firstName);        }        public void setEmail(String email) {            this.email.set(email);        }        @Override        public String toString() {            return firstName.getValue() + ":"                    + lastName.getValue();        }    }}

这样的话拿到这些数据就不用像Swing一样对Table重写数据了，一套数据直接放入TableView， TreeView中也能展示出来，大大简化了编码的时间和代价

而且ObservableList 能添加ChangeListener方法，对数据的操作都能通过它来获取监听，通知其他组件，方便！

以后再学习修改Cell的方法，争取把FX给用起来
