问题描述
我正在寻找一个好的windows GUI库的C ++。我认为理想的特征应该是：
I'm looking for a good windows GUI library for C++. The ideal characteristics in my opinion should be:
- 现代。 MFC，wxWidgets，Qt很久以前就开始了，他们不使用现代的C ++特性和标准库。
- 拥有丰富的控件， b>几乎无处不在的HTML的能力是一个幸福，我喜欢wxWidgets，当我不讨厌它。
- 开源。这是必须的。
- 以某种方式拥有表单设计师。是的，这将是巨大的。经过多年的德尔福工作，我每次都要手动指定控制尺寸。
- 免费商业使用。但是如果一些图书馆真的很好，那么我会考虑购买。
- 跨平台。这个规范只是一个打破☺。
- Modern. MFC, wxWidgets, Qt were started a long time ago and they don't use modern C++ features and standard library.
- Have a rich set of controls with decent features. The ability to drop HTML almost everywhere is a happiness for which I love wxWidgets when I don't hate it.
- Open source. It's the must. If sources are available after purchase then it's considered ok.
- Have a form designer in some way. Yeah, it would be great. After years of working with Delp I cry every time I have to specify control sizes by hand.
- Free for commercial use. But if some library is REALLY good, then I will consider buying it.
- Cross platform. This specification is just a tie-breaker ☺. I can live without this.
请向候选人推荐您的想法。每个答案都有一个库。
Please suggest your ideas for candidates. One library per answer please.
P.S。对不可避免的语法错误，我深感抱歉。英语不是我的母语。

推荐答案
我认为你写的Qt太快;它不使用标准库很多，但是与过时相比，具有不同的优先级。 QT容器使用迭代器，模板算法等，但有不同的迭代器模型; Qt迭代器在元素之间而不是在它们之间。这使得正向和反向遍历对称，并且清理一些边缘情况用于在遍历时插入和移除元素，虽然它的效率稍低。他们也提供STL式迭代器。它是GUI库IMO的有效选择;容器的性能不太可能是关键因素。
I think you're writing Qt off too quickly; it doesn't use the standard library much, but that has less to do with being obsolete than with having different priorities. The QT containers use iterators, template algorithms, etc, but have a different iterator model; Qt iterators point between elements instead of at them. This makes forward and reverse traversal symmetric, and cleans up some edge cases for inserting and removing elements while traversing, though it's a little less efficient. And they do provide STL-style iterators too. It's a valid choice for a GUI library IMO; performance of the containers is unlikely to be the critical factor.
对于预处理器（moc），将其想象为一个知道如何读取C ++头文件的IDL编译器而不是需要自己的语言。它不会预处理您的代码，它是直接编译的。它只是生成一个额外的cpp文件，包含信号/槽回调的封送处理，当它们跨线程边界并需要同步时，可能会变得麻烦。
As for the preprocessor (moc), think of it more as an IDL compiler that knows how to read C++ headers instead of needing its own language. It doesn't preprocess your code, which is compiled directly. It just generates an additional cpp file containing the marshaling for signal/slot callbacks, which can get rather messy when they cross thread boundaries and need synchronization.
Qt是免费的，如果你可以释放您的来源（即使是商业用途;有多少内部工具真正需要是专有的），如果您不能（没有单位使用费或任何特别烦人的）
Qt is free if you can release your sources (even for commercial use; how many in-house tools really need to be proprietary), and not unreasonably priced if you can't (no per-unit royalties or anything particularly annoying)
