mGi 是飞漫软件提供的一个输入法组件，该组件目前提供了软键盘输入法和手写输入法框架，并提供给用户管理输入法的容器，通过这个容器，用户还可以添加自定义的输入法。此外，对于软键盘输入法，用户可以自定义显示的键盘位图，并可添加不同的输入翻译方式（自带中文全拼输入法）。

mGi 现在已随着MiniGUI 3.0.12 版本一起开源, 可以在http://www.minigui.org/downloads/index.html下载.

以下是测试实例代码, mGi 采用configure默认配置, 如果采用--enable-mgdesktop-version, 要注意自己手动ShowWindow.
