libtidy几个问题

ccsdu2009 — Sat, 05 May 2012 08:43:00 GMT

1.不显�C��?br />只需要加载空回调函数卛_��
如下:

Bool cb(TidyDoc tdoc,TidyReportLevel lvl,uint line,uint col,ctmbstr mssg)
{
return no;
}

tidySetReportFilter(doc,(TidyReportFilter)cb);

2.昄��节点文本

    TidyBuffer buf;
    tidyBufInit(&buf);
    tidyNodeGetText(doc,body,&buf);
    printf("text:%s",buf.bp);
    tidyBufFree(&buf);

使用log4plus

ccsdu2009 — Thu, 15 Mar 2012 14:22:00 GMT

输出到控制台

#include <iostream>
#include <log4cplus/helpers/loglog.h>

using namespace std;
using namespace log4cplus::helpers;

void print_message()
{
    cout << "Entering print_message()" << endl;
    LogLog::getLogLog()->debug(LOG4CPLUS_TEXT("This is a Debug statement"));
    LogLog::getLogLog()->warn(LOG4CPLUS_TEXT("This is a Warning"));
    LogLog::getLogLog()->error(LOG4CPLUS_TEXT("This is a Error"));
    cout << "Exiting print_message()" << endl << endl;
}

int main()
{
    print_message();

    cout << "Turning on debug" << endl;
    LogLog::getLogLog()->setInternalDebugging(true);
    print_message();

    cout << "Turning on quiet mode" << endl;
    LogLog::getLogLog()->setQuietMode(true);
    print_message();
    system("pause");
    return 0;
}

另外一个例�?

#include "log4cplus/logger.h"
#include "log4cplus/consoleappender.h"
#include "log4cplus/loglevel.h"
#include <iomanip>

using namespace std;
using namespace log4cplus;

int main()
{
    SharedAppenderPtr append_1(new ConsoleAppender());
    append_1->setName(LOG4CPLUS_TEXT("First"));
    Logger::getRoot().addAppender(append_1);

    Logger root = Logger::getRoot();
    Logger test = Logger::getInstance(LOG4CPLUS_TEXT("test"));

    LOG4CPLUS_DEBUG(root,
                    "This is"
                    << " a reall"
                    << "y long message." << endl
                    << "Just testing it out" << endl
                    << "What do you think?");
    test.setLogLevel(NOT_SET_LOG_LEVEL);
    LOG4CPLUS_DEBUG(test, "This is a bool: " << true);
    LOG4CPLUS_INFO(test, "This is a char: " << 'x');
    LOG4CPLUS_INFO(test, "This is a short: " << (short)-100);
    LOG4CPLUS_INFO(test, "This is a unsigned short: " << (unsigned short)100);
    LOG4CPLUS_INFO(test, "This is a int: " << (int)1000);
    LOG4CPLUS_INFO(test, "This is a unsigned int: " << (unsigned int)1000);
    LOG4CPLUS_INFO(test, "This is a long(hex): " << hex << (long)100000000);
    LOG4CPLUS_INFO(test, "This is a unsigned long: " << (unsigned long)100000000);
    LOG4CPLUS_WARN(test, "This is a float: " << (float)1.2345);
    LOG4CPLUS_ERROR(test,
                    "This is a double: "
                    << setprecision(15)
                    << (double)1.2345234234);
    LOG4CPLUS_FATAL(test,
                    "This is a long double: "
                    << setprecision(15)
                    << (long double)123452342342.342);
    system("pause");
    return 0;
}

再来看几个输出到日志的小例子:

#include <log4cplus/logger.h>
#include <log4cplus/fileappender.h>
#include <log4cplus/layout.h>
#include <log4cplus/ndc.h>
#include <log4cplus/helpers/loglog.h>

using namespace log4cplus;

const int LOOP_COUNT = 20000;

int main()
{
    helpers::LogLog::getLogLog()->setInternalDebugging(true);
    SharedAppenderPtr append_1(new RollingFileAppender(LOG4CPLUS_TEXT("Test.log"),5*1024,5));
    append_1->setName(LOG4CPLUS_TEXT("LOG4PLUS"));
    append_1->setLayout(std::auto_ptr<Layout>(new TTCCLayout()));
    Logger::getRoot().addAppender(append_1);

    Logger root = Logger::getRoot();
    Logger test = Logger::getInstance(LOG4CPLUS_TEXT("test"));
    Logger subTest = Logger::getInstance(LOG4CPLUS_TEXT("test.subtest"));

    for(int i=0; i<LOOP_COUNT; ++i)
    {
        NDCContextCreator _context(LOG4CPLUS_TEXT("loop"));
        LOG4CPLUS_DEBUG(subTest, "Entering loop #" << i);
    }

    return 0
}

几点说明:
1.setInternalDebuging 是启用内部调试日志，不过具体作用不是很明��?br />2.Appender是实现日志输出的�{�略描述
一般情况下�Q�参考以上例子就��_��?br />

�?nbsp;GUI库应该分为几个大的模块呢? :)我想

�q�次的GUI库我�?x��)采用类似GUICHAN的方式，具体的GUI�q�不依赖于特定的囑�Ş接口�Q�而是采取插�g的方式动态加载，�q�样有助于提高其使用的广�?br>应该包含一个GUIRender

另外GUI库涉�?qi��ng)面比较�q�，需要有大量附加的数据结构比如XML�Q�图形处理，向量�Q�插�Ӟ��基本对象�Q�日志等。我们应该再加一个辅助库
于是有一个叫做Util的东�?br>
其次我们主要的GUI库类
�q�个是核�?br>我暂时给他�v个名字叫coregui�?br>�q�个是这个GUi的核�?br>其功能除�?ji��n)一般的GUI控�g对象之后�q�应该有控�g工厂�Q�控件池(��理�?�Q�控件数据串行化�Q�控件布局�Q�控件编辑，控�g动态加载，脚本处理�{�功能（��x��功能�q�比较多-不过��L��之前做的游戏引擎量要��很多）(j��)

分块��p��么几个了(ji��n)

在开发过�E�中�Q�我�?x��)一个一个GUI对象都脓(chu��ng)上来�Q�然后说明�ؓ(f��)什么要�q�样做，�q��上可能对应的设计模式�Q�要�z�d��zȝ��(⊙v�??�Q?br>

设计模式-原型�Ҏ(gu��)��

ccsdu2009 — Fri, 06 May 2011 14:22:00 GMT

一般来�?原型�Ҏ(gu��)��主要使用于快速生成和已存在对象基本一致的对象�?br>一般典型的例子是细�?y��u)分裂和孙�(zh��n)��I�变换出N的小猴子
不过我这里�D一个在GUI设计�q�程的例�?br>
假如一个面板上的同质按钮，他们仅文本不同，代表的逻辑不同�Q�其他信息是完全一致的�Q�比如皮肤，�Ҏ(gu��)��Q�大��等
按照一般方法可能会(x��)�q�样构造面�?br>

Button* btn1 = new Button();
btn1->SetSize(..);
btn1->SetBorder(..);
btn1->SetListener(..);
btn1->SetVisible(true);
btn1->SetParent(panel);
btn1->SetColor()
Button* btn2 =..
当然�q�有其他按钮:)

是不是很�?
借助原型模式
可以大大的简�?
比如:

Button *btn1 = new Button(panel);
Button *btn2= btn1->Clone();
Button *btn3= btn1->Clone();
Button *btn4= btn1->Clone();
然后只要讄��各个按钮对应的文本即�?/span>

��Z��(ji��n)使用原型�Ҏ(gu��)��我们需要做的仅仅是
�l�对象增加Clone接口和其实现卛_��
比如:

class AbstractWidget
{
public:
virtual AbstractWidget* Clone() = 0;

};

需要说明的是原型一般��用的是浅拯��
