javafx计算器 javafx制作计算器界面

本节概要：界面设计

本节将实现该项目的主界面。

首先使用IDEA创建一个普通的JavaFX项目（如果不会创建的话可以查看前面的文章），然后按照下图进行创建controller包、data包、styles包和view包。

并将创建的基本JavaFX项目的文件移到对应文件夹下。

并为sample.fxml文件添加如下内容（覆盖即可）：

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.text.*?>
<AnchorPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="650.0"
            prefWidth="800.0" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1"
            fx:controller="kindredCalculator.controller.Controller">
    <children>
        <VBox layoutX="32.0" layoutY="28.0" prefHeight="593.0" prefWidth="736.0">
            <children>
                <HBox alignment="CENTER" prefHeight="100.0" prefWidth="200.0">
                    <children>
                        <VBox alignment="CENTER" prefHeight="81.0" prefWidth="767.0" spacing="10.0">

    <stylesheets>

    </stylesheets>
</AnchorPane>

用Scene Builder查看如下：

其中各个按钮的相关事件监听器的设置均在代码中，可以打开Scene Builder进行查看修改设置。

注意，把代码放进去会爆红，所以还需要将Controller.java类的内容改为如下，意思是将事件监听器注册到控制器类中：

package kindredCalculator.controller;

import javafx.event.ActionEvent;

public class Controller {
    public void do_fatherButton_event(ActionEvent actionEvent) {
    }

    public void do_montherButton_event(ActionEvent actionEvent) {
    }

    public void do_sonButton_event(ActionEvent actionEvent) {
    }

    public void do_daughterButton_event(ActionEvent actionEvent) {
    }

    public void do_bigBrotherButton_event(ActionEvent actionEvent) {
    }

    public void do_smallBrotherButton_event(ActionEvent actionEvent) {
    }

    public void do_bigSisterButton_event(ActionEvent actionEvent) {
    }

    public void do_smallSisterButton_event(ActionEvent actionEvent) {
    }

    public void do_husbandButton_event(ActionEvent actionEvent) {
    }

    public void do_wifeButton_event(ActionEvent actionEvent) {
    }

    public void do_countButton_event(ActionEvent actionEvent) {
    }

    public void do_rebackButton_event(ActionEvent actionEvent) {
    }
    
    public void do_clearButton_event(ActionEvent actionEvent) {
    }
}

点击运行，会出现如下界面：

这是由于加载的这个界面是被作为Scene放入到Stage中的，但是Stage的尺寸大小是在Main.java中设置的，使用的是默认大小，没有进行改变。

所以需要将Stage的尺寸大小设置到与fxml文件中的界面大小一致才行。

所以Main.java文件的内容如下：

package kindredCalculator;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {
        Parent root = FXMLLoader.load(getClass().getResource("view/sample.fxml"));
        primaryStage.setTitle("亲戚关系计算器");
        primaryStage.setScene(new Scene(root, 800, 650));
        primaryStage.show();
    }


    public static void main(String[] args) {
        launch(args);
    }
}

运行程序，显示的结果界面如下：
