在JavaFX中使用Unicode字符 [英] Using Unicode characters with JavaFX

问题描述

我一直玩摇摆一段时间，现在决定退房。到目前为止，我发现与摇摆相比，使用起来更轻松，更有趣，但我遇到了一个小的减速带，经过几个小时的环顾四周，我找不到解决方案。

I've been playing around with swing for some time and decided to check out FX now. So far I'm finding it a lot easier and more fun to work with as compared to swing but I've run into a small speed bump and after hours of looking around I just can't find a solution.

当我尝试通过fxml文件添加它时，我无法使用\ u 如果我不使用fxml但我想要使用场景构建器，因为它更方便。
这是一小段代码：

I am unable to use \u when I try to add it through the fxml file It works fine if I don't use the fxml but I want to use the scene builder as it is more convenient. Here's the small piece of code:

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

<?import javafx.scene.control.Button?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.layout.AnchorPane?>

<AnchorPane id="AnchorPane" prefHeight="200" prefWidth="320" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8.0.131" fx:controller="baitform.designDocController">
    <children>
        <Button fx:id="button" layoutX="126" layoutY="90" onAction="#handleButtonAction" text="Click Me!" />
        <Label layoutX="145.0" layoutY="129.0" text="\u0644\u0627\u062B\u0627\u0646\u0649" />
    </children>
</AnchorPane>

我一直遇到的错误是

引起：javafx.fxml.LoadException：转义序列无效。

Caused by: javafx.fxml.LoadException: Invalid escape sequence.

不确定是否相关，但我使用 jdk1.8.0_131 & netbeans 8.2

Not sure if relevant, but I'm using jdk1.8.0_131 & netbeans 8.2

如果有人能指出我正确的方向，我真的很感激。

If anyone could point me in the right direction here I'd really appreciate it.

推荐答案

FXML是一个XML，所以你需要使用XML转义：

FXML is an XML, and so you need to use XML escaping:

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

<?import javafx.scene.control.Button?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.layout.AnchorPane?>

<AnchorPane id="AnchorPane" prefHeight="200" prefWidth="320" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8.0.131" fx:controller="baitform.designDocController">
    <children>
        <Button fx:id="button" layoutX="126" layoutY="90" onAction="#handleButtonAction" text="Click Me!" />
        <Label layoutX="145.0" layoutY="129.0" text="&#x0644;&#x0627;&#x062B;&#x0627;&#x0646;&#x0649;" />
    </children>
</AnchorPane>

话虽如此，如果您能够输入字符，您可以按原样插入它们。

That being said, if you are able to input the characters, you can just insert them as is.
