最近工作中要用php重做一個之前用.net實現的工具客戶端。準備用php+gtk做，於是查閱資料先做個小的demo熟悉下。
gtk這個東西資料太少了，這裏先附上幾個鏈接：
1.gtk的文檔（吐槽下很簡陋）：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.鳥哥的demo：http://www.laruence.com/2009/05/26/871.html
好了，附上自己的代碼

弄好之後起來的效果：
先這樣，以後有時間重寫
