Winelib+Qt

Winelib User's Guide - WineHQ Wiki

Winelib is a development toolkit which allows you to compile your Windows applications on Unix.

Most of Winelib code consists of the Win32 API implementation. Fortunately this part is 100 percent shared with Wine. The remainder consists of Windows compatible headers and tools like the resource compiler (and even these are used when compiling Wine).

Thanks to the above, Winelib supports most C and C++ source code, resource and message files, and can generate graphical or console applications as well as dynamic libraries.

What is not supported is 16-bit source code as the types it depends on (especially segmented pointers) are not supported by Unix compilers. Also missing are some of the more exotic features of Microsoft compilers like native COM support and structured exception handling. So you may need to perform some modifications in your code when recompiling your application with Winelib. This guide is here to help you in this task.

What you gain by recompiling your application with Winelib is the ability to make calls to Unix APIs, directly from your Windows source code. This allows for a better integration with the Unix environment than is allowed by running an unmodified Windows application running in Wine. Another benefit is that a Winelib application can relatively easily be recompiled on a non-Intel architecture and run there without the need for a slow software emulation of the processor.

用CreateWindow等WIN32 API写界面太费事了。What if只把Qt里GUI的部分搬过来？网络I/O有select足矣，客户端要啥网络性能。Windows下有select(). 文件I/O有fstream和stdio. C++的string够了，用不着各种各样的String. 

桌面虚拟化技术非常多。很可能已经有了在浏览器里用JS+CSS画个Explorer，打开的是服务器上的文件。不同用户共享文件极其方便，张总不用担心在办公室里Ctrl-C家里不能Ctrl-V了。:-) 真有人备份时只备份了一堆快捷方式。非常惭愧，学电脑的我并不会恢复格式化后的硬盘上的文件，我倒是会备份文件。
