PHP+GTK2 初体验，简单计算器客户端

Posted 2020-10-29 叫我超人先生

　　最近工作中要用php重做一个之前用.net实现的工具客户端。准备用php+gtk做，于是查阅资料先做个小的demo熟悉下。

　　gtk这个东西资料太少了，这里先附上几个链接：

　　1.gtk的文档（吐槽下很简陋）：http://gtk.php.net/manual/en/html/gtk/gtk.gtkwindow.html

 

　　2.gtk布局 ：http://www.laruence.com/2009/05/26/871.html

　　3.鸟哥的demo：http://www.laruence.com/2009/05/26/871.html

　　好了，附上自己的代码
