第一个wxWidgets Demo简单实现，及VC2008下的环境设置！

一个wxWidgets简单设置及实现！用于学习wxWidgets入门的实例！

 

建立一个WIN32项目空工程，接着设置一下该工程的VS2008开发环境，设置方法如下：

一、中文环境的VS2008如下：

设置项:  C/C++/常规/附加包含目录
设置内容:  C:/wxWidgets-2.8.10/include;C:/wxWidgets-2.8.10/include/msvc

设置项:  C/C++/预处理器/预处理器定义
设置内容:WIN32;_DEBUG;_WINDOWS;__WXMSW__;__WXDEBUG__

设置项:  C/C++/代码生成/运行库
设置内容: 多线程DLL （/MD）

设置项:   链接器/常规/附加库目录
设置内容: C:/wxWidgets-2.8.10/lib/vc_lib

设置项:  链接器/输入/附加依赖项
设置内容:kernel32.lib user32.lib gdi32.lib comdlg32.lib winspool.lib winmm.lib shell32.lib

comctl32.lib ole32.lib oleaut32.lib uuid.lib rpcrt4.lib advapi32.lib wsock32.lib odbc32.lib

opengl32.lib

 

二、英文环境设置如下：

 

 

1，%WXPATH%可以置换为绝对路径，如：安装包路径 c:/wxWidgets  一定注意路径，别写错了！

2，%WXPATH%也可以在我的电脑-》属性-》环境变量中添加，相应上就OK了！

Configuration Properties/C/C++/General/Additional Include Directories:
%WXPATH%/include;%WXPATH%/include/msvc

 

 

Configuration Properties/C/C++/Preprocessor/Preprocessor Definitions:
WIN32;NDEBUG;_WINDOWS;__WXMSW__

如果是[Debug]就还要加上__WXDEBUG__，变成：

WIN32;_DEBUG;_WINDOWS;__WXMSW__;__WXDEBUG__

Configuration Properties/C/C++/Code Generation/Runtime Library:
Multi-threaded (/MT)

Multi-threaded Debug(/MTd)  如果是DEbug就设这行,也可以根据自已实行情况调试

Configuration Properties/Linker/General/Additional Library Directories:
%WXPATH%/lib/vc_lib

Configuration Properties/Linker/Input/Additional Dependencies:
kernel32.lib user32.lib gdi32.lib comdlg32.lib winspool.lib winmm.lib shell32.lib comctl32.lib ole32.lib oleaut32.lib uuid.lib rpcrt4.lib advapi32.lib wsock32.lib odbc32.lib opengl32.lib

 

这些静态链接库都是一些可能会使用到的 Windows 系统的库，根据需要增减，比如我从来不用odbc，就不需要在这里添加 odbc32.lib。而 wxWidgets 的静态库会自动添加到工程中，不需要在这里设置，在 %WXPATH%/include/msvc/wx/setup.h 文件中可以看到加载这些库的代码。
编译成依赖 DLL 的执行文件还需要加上预处理指令 WXUSINGDLL
用 UNICODE 编译则需要加上预处理指令 _UNICODE
还有一种 Universal 编译，要加上预处理指令 __WXUNIVERSAL__
这样一个普通的 wxWdigets 项目就设置好了。

 

复制以下代码添加到你的CPP文件中，进行编译，测试，OK！

错误处理：
一、打不到头文件 wx/wx.h
解决方案：查找以上路径设置，查看安装包的路径如：C:/wxWidgets

二、找不到 mondrian.xpm
解决方案: 此文件是一个图形资源，COPY(拷贝)一个mondrian.xpm放在你的工程下面,跟你的CPP文件同一

级目录！

三、error LNK2005: _exit 已经在 LIBCMTD.lib(crt0dat.obj) 中定义
 设置工程属性:C/C++/代码生成/运行库 这一项的选项为多线程DLL （/MD），如还有错误，可以试选其

它几项。
