[英]Can we create GUI for standalone application using html and javascript?
I have a Java program which until now used to get the input from command line and then proceed accordingly.我有一个 Java 程序,直到现在它还用于从命令行获取输入,然后相应地进行。
Now, I want to have a basic GUI for this.现在,我想要一个基本的 GUI。 It will need a few buttons which will trigger the events.
它需要一些按钮来触发事件。 I am experienced in HTML and JavaScript. Is it possible to write in HTML (or similar syntax) to generate the GUI?
我在 HTML 和 JavaScript 中有经验。是否可以编写 HTML(或类似语法)来生成 GUI?
I don't want to go in Swing and awt solution, because I would rather concentrate on the main program than on the GUI.我不想在 Swing 和 awt 解决方案中使用 go,因为我宁愿专注于主程序而不是 GUI。
Here's another alternative.这是另一种选择。 See also How to Use HTML in Swing Components .

toolBar.add(new JButton("Event " + ii));
if (ii%2==0) {

gui.add(toolBar, BorderLayout.NORTH);
gui.add( new JScrollPane(new JTextArea(5,30)), BorderLayout.CENTER );
