运行chrome ui

深碍√TFBOYSˉ_ 2022-07-16 14:53 97阅读 0赞

最近看了一下**chrome UI 学习笔记**（[http://blog.chinaunix.net/u2/76055/showart.php?id=2093274][http_blog.chinaunix.net_u2_76055_showart.php_id_2093274]），觉得chrome的ui架构不错，将很多基本控件进行了封装，这样写出来的ui就可以运行在windows，linux，mac机上，但其比qt和wxwidget轻量化，应该可以抽离出来，单独来作为一个简易的图形库。另外，chrome对多语言和皮肤等处理都很值得参考。在这里面学到了一个技巧是，设置完cygwin的环境后就可以在bat里面运行linux的相关命令了（[http://www.oschina.net/code/explore/chromium.r67069/chrome/tools/build/win/version.bat][http_www.oschina.net_code_explore_chromium.r67069_chrome_tools_build_win_version.bat]）：

:: Put cygwin in the path  
call %SolutionDir%/../third\_party/cygwin/setup\_env.bat  
:: Load version digits as environment variables  
cat %SolutionDir%/VERSION | sed "s//(.\*/)/set /1/" > %VarsBat%

看完了**chrome UI 学习笔记**，就想自己搭建环境来跑跑相关的例子，但将pdf的例子拷贝下来后，设置好编译环境，编过去了，却发现运行不起来。根据中断点的地方，可以看出是相关环境没有初始化，但该初始化那些环境呢？网上也有人问，作者的回答是：  
  
1.多个线程的启动和绑定  
  
2.PathService初始化  
  
3.资源文件初始化  
  
4.国际化判断和加载  
  
5.如果在Windows 平台下，需要初始化的一些关于wtl和com的模块。

但该怎么样初始化作者没讲？看来只能自己去找了。参考d:/project/chrome/src/src/chrome/app/chrome\_dll\_main.cc这个文件，同时参考[http://xjchilli.blog.163.com/blog/static/453477392010612111245425/][http_xjchilli.blog.163.com_blog_static_453477392010612111245425]，经过几次尝试后总算跑起来了，下面就说一下对应的代码：

1.多个线程的启动和绑定 可以不需要

2.PathService初始化

app::RegisterPathProvider();

3 4.资源文件初始化和国际化判断和加载

bool icu\_result = icu\_util::Initialize();

std::string app\_locale = ResourceBundle::InitSharedInstance("en-US");

5.如果在Windows 平台下，需要初始化的一些关于wtl和com的模块。

\#define \_WTL\_USE\_CSTRING

\#include // base ATL classes  
\#include // base WTL classes  
extern CAppModule \_Module; // WTL version of CComModule  
\#include // ATL GUI classes  
\#include // WTL frame window classes  
\#include // WTL utility classes like CString  
\#include // WTL enhanced msg map macros

OleInitialize(NULL);

运行的结果如图：
