UI库的设计问题 [英] Design question for UI library
问题描述
大家好，
我正在用C ++编写一个小型用户界面库（我知道它已经完成了b / b
，但它很好用于学习）。
无论如何，我需要一些软件设计的帮助/建议
架构。我面临的问题是控件可以有很多状态......例如，按钮可以有各种形状
（圆形，方形，其他一些）自定义几何）。此外，它可能是
位图，纹理，仅文本，带位图的文本等等。所以，你得到了
图片。为这些中的每一个设置一个专门的Button类将很难维护。
所以，我对你的专家的问题是你如何组织一个小部件图书馆
就是这样。我建议您考虑哪些设计模式？
任何建议都会受到赞赏。
谢谢和欢呼！

Hi everyone,
I am writing a small user interface library in C++ (I know it has been
done to death, but it is good for learning ).
Anyways, I need some help/advice with the deisgn of the software
architecture. The problem I am facing is that a control can have so
many states... For example, a button could be have various shapes
(rounded, square, some other custom geometry). Also, it could be
bitmapped, textured, text only, text with bitmap etc. So, you get the
picture. Having a specialized Button class for each of these would be
very difficult to maintain.
So, my question to you gurus is how would you organize a widget library
like that. What design patterns would you recommend that I look into?
Any advice would be appreciated.
Thanks and cheers!

不要制作具有不同属性的单独类按钮。对于不同/事物/使用
不同的类。如果你想能够在b / b
之间选择一个圆形按钮和一个方形按钮，
将这个选项作为类接口中的属性公开。
Don''t make separate classes buttons with different properties. Use
different classes for different /things/. If you want to be able to
choose between a rounded button and a square button for example,
expose this choice as a property in the class interface.

这篇帖子在这里是偏离主题的，因为它不涉及C ++ *语言*
本身（参见FAQ：
http://www.parashift.com/c++ -faq点燃.... HTML＃帮助-5.9）。试试
comp.software.patterns或comp.object。
干杯！ --M
This post is off-topic here, as it does not concern the C++ *language*
proper (see the FAQ:
http://www.parashift.com/c++-faq-lit....html#faq-5.9). Try in
comp.software.patterns or comp.object.
Cheers! --M

OT：这只是一种方法，但它真的不是设计
