对于枚举类,我们希望在数据库中存放一个有意义的英文字符串,在界面上显示一个有意义的中文字符串。所以为枚举类设置两个属性,如以下DataStatusEnum(数据状态枚举):
package com.lirong.javafx.demo.j3003;
/**
* <p>Title: 平台公共 -- 值对象</p>
* <p>Description: </p>
* <p>Copyright: Copyright (c) 2015</p>
* <p>Compary: lrJAP.com</p>
*
* @author yujj
* @version 1.1.1
* @date 2017-12-04
*/
public enum DataStatusEnum {
INIT("Init", "初始化"),
NORMAL("Normal", "正常"),
FROZEN("Frozen", "冻结"),
DISCARD("Discard", "作废");
private String code;
private String value;
DataStatusEnum(String code, String value) {
this.code = code;
this.value = value;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
@Override
public String toString() {
return getValue();
}
}
DataStatusEnum中,code用于持久化到数据库中,value用于在界面上展示。其中有四个枚举值。
测试类:
package com.lirong.javafx.demo.j3003;
import javafx.application.Application;
import javafx.geometry.HPos;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.ComboBox;
import javafx.scene.control.Label;
import javafx.scene.control.TextArea;
import javafx.scene.layout.ColumnConstraints;
import javafx.scene.layout.GridPane;
import javafx.scene.layout.Priority;
import javafx.stage.Stage;
/**

* @since 9.0.4
*/
public class TestEnumComboBox extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) throws Exception {
Label lblEnum = new Label("数据状态:");
ComboBox<DataStatusEnum> comboEnum = new ComboBox<>();
TextArea textConsole = new TextArea();
GridPane gridPane = new GridPane();
gridPane.setPadding(new Insets(10));
gridPane.setVgap(10);
gridPane.setHgap(10);
ColumnConstraints col1 = new ColumnConstraints();
col1.setPercentWidth(40);
ColumnConstraints col2 = new ColumnConstraints();
col2.setPercentWidth(60);
gridPane.getColumnConstraints().addAll(col1, col2);
gridPane.addRow(0, lblEnum, comboEnum);
// label右对齐
GridPane.setHalignment(lblEnum, HPos.RIGHT);
// 使用Combobox充满整个Cell
comboEnum.setMaxWidth(Double.MAX_VALUE);
GridPane.setHgrow(comboEnum, Priority.ALWAYS);
// 为ComboBox赋值
comboEnum.getItems().setAll(DataStatusEnum.values());
// 监听ComboBox变化
comboEnum.getSelectionModel().selectedItemProperty().addListener((observable, oldValue, newValue) ->
textConsole.appendText(String.format("选中的枚举信息,code=%s, value=%s。%s", newValue.getCode(), newValue.getValue(), System.getProperty("line.separator"))))
;
gridPane.add(textConsole, 0, 1, 2, 2);
Scene scene = new Scene(gridPane, 400, 300);
primaryStage.setScene(scene);
primaryStage.show();
}
}
运行效果:
