CAD ObjectArx 二次开发 创建工具栏实现点击button出现抽屉式菜单

实现在CAD中创建工具栏并添加菜单命令，如下图

参照文章：

cad—菜单，工具栏，屏幕菜单，增强工具栏

主要实现路径是通过创建一个可停靠窗口，并在其中创建toolbutton并给button点击事件添加命令，将子菜单menu显示在button位置，如果需要更加顺滑的交互，需要重写一下menu的样式。
像文中所说，可以通过一个xml文件来控制控件，这样可以省略修改交互的步骤，
我这里只是做出了单纯横向布置的实现和button边框背景取消，还需要增加自适应修改的内容，让侧边顶部都可以实现。
代码逻辑也没有什么可以说的，直接将代码放到下面：
