gtk init and layout of object

Initializing the GTK+ libraries is extremely simple for most applications.

By calling gtk_init(),

all initialization work is automatically performed for you.
It begins by setting up the GTK+ environment,

including obtaining the GDK display and
preparing the GLib main event loop and

basic signal handling.

vim 中的制动不全的功能， 它默认回去找/usr/include 等目录
ctags -R 递归生成 ctags 生成的文件名是 ctags， 然后复制到vim编辑的当前目录（看vim的时候好像是可以指定ctags的 ？）

然后就可以使用 ctrl+p 补全了

执行ctags -R
