关于CEGUI的中文输入与显示
来源：互联网 发布：淘宝扫码领取粮票 编辑：程序博客网 时间：2024/04/29 04:27
项目终于进行到中文的输入和显示了，貌似这是个老话题，同样还是先求助于前辈，很多方案，照着做了一下，很好用，整理一个版本，希望能方便到更多需要用到这个功能的朋友。
感谢腾讯网友襄樊石开和Azure。
中文的显示：
中文的显示很简单，因为CEGUI本来就支持utf-8，只是他默认的demo里没有带中文字体，自己根据.ttf文件创建一个就是了。
Step1: 在控制面板里找到一种.ttf格式的字体，我用了自己喜欢的微软雅黑，文件名为MSYH.TTF，将其拷贝至datafiles文件下的font里。
Step2: 在font文件夹下新建一个记事本文件，另存为msyh.font，里面输入
view plaincopy to clipboardprint?
<?xml version="1.0" ?>
<Font Name="MSYH" Filename="MSYH.TTF" Type="FreeType" Size="10" NativeHorzRes="800" NativeVertRes="600" AutoScaled="true" />
<?xml version="1.0" ?>
<Font Name="MSYH" Filename="MSYH.TTF" Type="FreeType" Size="10" NativeHorzRes="800" NativeVertRes="600" AutoScaled="true" />
Step3: 以CEGUI自带的FontDemo为例，如下修改源码：
在static const char *FontList [] = {}里添加项 "MSYH"(就是字体名，.font文件里定义的)
在
view plaincopy to clipboardprint?
static struct
{
utf8 *Language;
utf8 *Text;
} LangList []
static struct
{
utf8 *Language;
utf8 *Text;
} LangList []
的最后加上
view plaincopy to clipboardprint?
{
(utf8 *)"MSYH. Chinese",
(utf8 *)"简体中文测试，微软雅黑/n",
}
{
(utf8 *)"MSYH. Chinese",
(utf8 *)"简体中文测试，微软雅黑/n",
}
Step4: 将FontDemo对应的FontDemo.layout文件用记事本打开，另存为utf-8。
OK，现在看看你的成就吧，呵呵。
中文的输入：
中文的输入比较复杂，涉及到一些底层的东西，这里拿来主义，不进行深究，只简单的完成功能。
需要修改CEGUISampleHelper里的Win32AppHelper.h和Win32AppHelper.cpp，下面直接贴上修改后的源文件，可以直接将原文件覆盖掉重新编译。
