GUI programming in Scala
提问by thatismatt
I'm trying to learn Scala, and I'd like to learn by writing a simple swing app, but I'm unsure what GUI programing looks like in a functional world, and specifically when using Scala.
我正在尝试学习 Scala，我想通过编写一个简单的 Swing 应用程序来学习，但我不确定 GUI 编程在函数式世界中的样子，特别是在使用 Scala 时。
Any pointers, or tutorials, or gotchas when coming from an OO/Java background would be really welcome.
任何来自 OO/Java 背景的指针、教程或问题都将非常受欢迎。

The Programming in Scalabook did contain an overview of the scala-swing project. The book is very good, overall, and worth the money as a general reference, and sounds just like what you're looking for.
将在Scala编程书确实含有斯卡拉摆项目的概述。总的来说，这本书非常好，作为一般参考物有所值，听起来就像您要找的东西。
Scala-swing is a "wrapping" library approach, so, I wouldn't call it functional, really. State is mutated all over the place, mostly because that's just how Swing works.
Scala-swing 是一种“包装”库方法，因此，我真的不会称其为函数式的。State 到处都是变异的，主要是因为这就是 Swing 的工作方式。
I'm not really aware of many "free as in beer" resources for this topic yet, and I think the Syngeca scala wikiprobably lists some preliminary approaches that became scala-swing, but, that's just a guess. :)
我还没有真正了解有关此主题的许多“像啤酒一样免费”的资源，我认为Syngeca scala wiki可能列出了一些成为 scala-swing 的初步方法，但这只是一个猜测。:)

The only functional paradigm of GUI programming I know of is Lisp's Cells.
我所知道的唯一的 GUI 编程功能范例是 Lisp 的 Cells。
Scala's present Swing library is reactive, which isn't bad. It's being reworked for version 2.8, I have heard.
Scala 现有的 Swing 库是响应式的，这还不错。我听说它正在为 2.8 版重新设计。
There are, though, alternative frameworks. One recent one, for instance, is a Scala wrapper for SWT.
但是，有替代框架。其中最近的一个，例如，是斯卡拉包装的SWT。
I think that, at this point, there hasn't been enough projects done for any particular pattern to emerge as a superior choice. I'd advise taking a look at everything out there, and choosing one that fits you better. Who knows? You might even become a major contributor to the best Scala GUI framework that comes to be...
我认为，在这一点上，还没有足够的项目让任何特定模式成为更好的选择。我建议你看看那里的所有东西，然后选择一个更适合你的。谁知道？您甚至可能成为最好的 Scala GUI 框架的主要贡献者……
