对于C++界面库：使用Graphic Element Template制作按钮模板的说明进行详细介绍，模板的属性一共有6个：x、y、w、h、state、content，其中state有normal、hot和press三个取值。XML、代码和截图如下：
下面的模板文件有两个模板，分别是background和button。background制作玻璃效果，button给background加上一个边框，展示了property evaluation和template reference的功能：

程序由4个按钮组成，4个按钮都是button的实例化，但是只处理了最后一个按钮的消息。因为现在只有画图，所以消息处理部分是手动的。下面是截图：
