最近看了一下chrome UI 学习笔记（），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（）：

:: 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，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：

为了方便大家自己搭建，现给出完整的测试代码：

//test.h#ifndef _TEST_CHROME_VIEWS_#define _TEST_CHROME_VIEWS_#include "views/view.h"#include "views/window/window_delegate.h"#include "views/controls/button/button.h"class TestWindow : public views::View, public views::WindowDelegate{public: virtual View* GetContentsView() { return this; } virtual gfx::Size GetPreferredSize(){ return gfx::Size(400,300); } static void CreateTestWindow();};namespace views{ class Label; class TextButton;}namespace gfx{ class Canvas;}class ChromeCanvas;class TestWindow_Widget : public views::View, public views::WindowDelegate, public views::ButtonListener{public: TestWindow_Widget(); virtual View* GetContentsView() { return this; } virtual gfx::Size GetPreferredSize(){ return gfx::Size(400,300); } virtual void Layout(); virtual void Paint(gfx::Canvas* canvas); virtual void ButtonPressed(views::Button* sender,const views::Event &event); static void CreateTestWindow();private: views::Label * lable_; views::TextButton * button_;};#endif
