javafx以编程方式设置虚拟键盘的参数 [英] javafx programmatically set arguments for virtual keyboard

问题描述

我有一个桌面应用程序，将在没有键盘的计算机上使用，输入将在触摸屏上。从eclipse运行时，我可以让虚拟键盘显示在文本字段上。我使用了这些参数

I have a desktop application that will be used on computers with no keyboard, input will be on a touch screen. I can get the virtual keyboard to show up on textfields fine when running from eclipse. I used these arguments

-Dcom.sun.javafx.touch=true 
-Dcom.sun.javafx.isEmbedded=true 
-Dcom.sun.javafx.virtualKeyboard=none

以下链接显示我在哪里添加参数。
如何添加命令在Eclipse中运行java代码时的行参数？

The following link shows me where to add the arguments. how to add command line parameters when running java code in Eclipse?

当我创建一个可运行的jar文件时，键盘不显示。我正在寻找一种以编程方式设置这些参数的方法，以便runnable jar文件将在任何计算机上显示虚拟键盘。任何帮助将不胜感激。

When I make a runnable jar file the keyboard does not show up. I am looking for a way to set these arguments programmatically so that the runnable jar file will display the virtual keyboard on any computer. Any help will be greatly appreciated.

我能找到的唯一可行解决方案来自这里
javafx应用程序的Gradle构建：由于缺少系统属性，虚拟键盘无法正常工作

The only working solution I could find came from here Gradle build for javafx application: Virtual Keyboard is not working due to missing System property

在调用应用程序原始main方法之前创建一个包装类并设置系统属性。

Create a wrapper class and set the system properties before invoking the applications original main method.

public class MainWrapper {

    public static void main(String[] args) throws Exception 
    {  // application - package name
        Class<?> app = Class.forName("application.Main");         
        Method main = app.getDeclaredMethod("main", String[].class);     
        System.setProperty("com.sun.javafx.isEmbedded", "true"); 
        System.setProperty("com.sun.javafx.touch", "true");          
        System.setProperty("com.sun.javafx.virtualKeyboard", "javafx");     
        Object[] arguments = new Object[]{args};
        main.invoke(null, arguments);
    }
}

制作runnable jar文件时只需指向MainWrapper启动配置的类。

When making the runnable jar file just point to the MainWrapper class for the launch configuration.
