GTK+浅谈之八表格列表

一、简介

Gtk+2.0表格控件十分有用，（GtkCList）可以向表格中添加图像、文字，对数据进行排序，设定表格控件的背景，设置各单元格的属性等。但不能编辑单元格（需要使用树视图控件GtkTreeView）。

二、详解

2、编译及运行

gcc -o grid grid.c `pkg-config --libs --cflags gtk+-2.0`

三、总结

（1）列表控件中还有很多的函数没有应用到，等以后项目中有需求时再进行扩展。

（2）源码已上传到CSDN：http://download.csdn.net/detail/taiyang1987912/9123689。

（3）若有建议，请留言，在此先感谢！
