javafX8初探（表格）

本节，我们将学习如何在JavaFX应用中操作表格。比如：添加表格，为表格填充数据、编辑表格的行。

JavaFX中提供了一些类让我们更方便的操作表格，最重要的类有TableView、TableColumn和TableCell。我们可以通过实现数据模型和使用单元工厂来填充表格。这些类都提供了列排序和改变列的宽度。

下图是一个典型的地址信息表格：

创建一个表格

import javafx.application.Application;import javafx.geometry.Insets;import javafx.scene.Group;import javafx.scene.Scene;import javafx.scene.control.Label;import javafx.scene.control.TableColumn;import javafx.scene.control.TableView;import javafx.scene.layout.VBox;import javafx.scene.text.Font;import javafx.stage.Stage; public class TableViewSample extends Application {     private final TableView table = new TableView();    public static void main(String[] args) {        launch(args);    }     @Override    public void start(Stage stage) {        Scene scene = new Scene(new Group());        stage.setTitle("Table View Sample");        stage.setWidth(300);        stage.setHeight(500);         final Label label = new Label("Address Book");        label.setFont(new Font("Arial", 20));         table.setEditable(true);         TableColumn firstNameCol = new TableColumn("First Name");        TableColumn lastNameCol = new TableColumn("Last Name");        TableColumn emailCol = new TableColumn("Email");                table.getColumns().addAll(firstNameCol, lastNameCol, emailCol);         final VBox vbox = new VBox();        vbox.setSpacing(5);        vbox.setPadding(new Insets(10, 0, 0, 10));        vbox.getChildren().addAll(label, table);         ((Group) scene.getRoot()).getChildren().addAll(vbox);         stage.setScene(scene);        stage.show();    }}

 

表格控件是通过TableView来创建的，并且被添加到一个VBox的容器中，当然你也可以直接把这个表格添加到场景中。

然后创建了3列来存数地址信息：first name、last name和邮件地址。列是通过TableColumn类来创建的。

然后getColumns方法添加了之前创建的3列。在你自己的应用中，你可以通过这个方法来增加和删除列。

编译运行，如下图所示：

你也可以通过setVisble来设置列的可见性。举个例子。如果你的例子中药隐藏邮件地址的列。你可以使用下面的方法。EmailCol.setVisble(false);

如果你的表格需要更复杂的表现，比如需要嵌套列。举个例子，如果一个人有两个邮件地址。那么我们需要两列来存储第一个和第二个邮件地址。我们创建两个子列，然后通过getColumns方法来添加这两个子列。

TableColumn firstEmailCol = new TableColumn("Primary");TableColumn secondEmailCol = new TableColumn("Secondary");emailCol.getColumns().addAll(firstEmailCol, secondEmailCol);

 

编译运行代码，如下图所示：

尽管这个表格已经添加到我们的应用中了，但是其中没有内容，显示了“No content

In table”.我们可以通过，setPlaceholder方法来指定没有数据时的显示内容。

定义数据模型

当你创建了一个表格后，最好能有一个类定义数据模型，然后提供方法和域来更好的为表格服务。下面我们使用一个Person类来定义地址表格中的数据。

public static class Person {    private final SimpleStringProperty firstName;    private final SimpleStringProperty lastName;    private final SimpleStringProperty 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 String getFirstName() {        return firstName.get();    }    public void setFirstName(String fName) {        firstName.set(fName);    }            public String getLastName() {        return lastName.get();    }    public void setLastName(String fName) {        lastName.set(fName);    }        public String getEmail() {        return email.get();    }    public void setEmail(String fName) {        email.set(fName);    }        }

 

其中firstName，lastName和email 3个字符串属性代表了表格中的3个列。

而且没有属性都提供了get和set方法。Get方法返回属性的值，set方法为属性赋值。

然后我们使用Person类创建一个ObservableList，定义多行数据。

final ObservableList<Person> data = FXCollections.observableArrayList(    new Person("Jacob", "Smith", "[e-mail]"),    new Person("Isabella", "Johnson", "[e-mail]"),    new Person("Ethan", "Williams", "[e-mail]"),    new Person("Emma", "Jones", "[e-mail]"),    new Person("Michael", "Brown", "[e-mail]"));

 

下一步就是把这些数据关联到表格中。我们可以通过属性的名字来关联。

firstNameCol.setCellValueFactory(    new PropertyValueFactory<>("firstName"));lastNameCol.setCellValueFactory(    new PropertyValueFactory<>("lastName"));emailCol.setCellValueFactory(    new PropertyValueFactory<>("email"));

 

SetCellValueFactory方法指定了每一列的单元格工厂。单元格的属性是通过PropertyValueFactory类来实现的。

当数据模型定义好后并且也关联到表格中，我们就这个通过TableView的setItems方法来添加数据了。代码如下：

import javafx.application.Application;import javafx.beans.property.SimpleStringProperty;import javafx.collections.FXCollections;import javafx.collections.ObservableList;import javafx.geometry.Insets;import javafx.scene.Group;import javafx.scene.Scene;import javafx.scene.control.Label;import javafx.scene.control.TableColumn;import javafx.scene.control.TableView;import javafx.scene.control.cell.PropertyValueFactory;import javafx.scene.layout.VBox;import javafx.scene.text.Font;import javafx.stage.Stage; public class TableViewSample extends Application {     private final TableView<Person> table = new TableView<>();    private final ObservableList<Person> data =        FXCollections.observableArrayList(            new Person("Jacob", "Smith", "[e-mail]"),            new Person("Isabella", "Johnson", "[e-mail]"),            new Person("Ethan", "Williams", "[e-mail]"),            new Person("Emma", "Jones", "[e-mail]"),            new Person("Michael", "Brown", "[e-mail]")        );       public static void main(String[] args) {        launch(args);    }     @Override    public void start(Stage stage) {        Scene scene = new Scene(new Group());        stage.setTitle("Table View Sample");        stage.setWidth(450);        stage.setHeight(500);         final Label label = new Label("Address Book");        label.setFont(new Font("Arial", 20));         table.setEditable(true);         TableColumn firstNameCol = new TableColumn("First Name");        firstNameCol.setMinWidth(100);        firstNameCol.setCellValueFactory(                new PropertyValueFactory<>("firstName"));         TableColumn lastNameCol = new TableColumn("Last Name");        lastNameCol.setMinWidth(100);        lastNameCol.setCellValueFactory(                new PropertyValueFactory<>("lastName"));         TableColumn emailCol = new TableColumn("Email");        emailCol.setMinWidth(200);        emailCol.setCellValueFactory(                new PropertyValueFactory<>("email"));         table.setItems(data);        table.getColumns().addAll(firstNameCol, lastNameCol, emailCol);         final VBox vbox = new VBox();        vbox.setSpacing(5);        vbox.setPadding(new Insets(10, 0, 0, 10));        vbox.getChildren().addAll(label, table);         ((Group) scene.getRoot()).getChildren().addAll(vbox);         stage.setScene(scene);        stage.show();    }     public static class Person {         private final SimpleStringProperty firstName;        private final SimpleStringProperty lastName;        private final SimpleStringProperty 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 String getFirstName() {            return firstName.get();        }         public void setFirstName(String fName) {            firstName.set(fName);        }         public String getLastName() {            return lastName.get();        }         public void setLastName(String fName) {            lastName.set(fName);        }         public String getEmail() {            return email.get();        }         public void setEmail(String fName) {            email.set(fName);        }    }} 

编译运行代码，如下图所示：

运行，如下图所示：

排序

TableView类为表格提供了排序列的能力,用户可以通过单击列头来实现排序.第一次单击按照升序排列，第二次单击按照降序排列，第三次单击不排序。默认不排序。

用户也可以按照多行排序。当单击列头的是由按住Shift键就可以。如下图所示：

作为开发者，我们可以指定列的排序类型。可用通过setSortType方法来指定比如emailCol.setSortType(TableColumn.SortType.SESCENDING);

我们也可以通过setSortable（false）方法来禁止排序。
