怎么添加自定义菜单中菜单项事件的？我自己做的菜单：
acadapplication acadapp;
acadapp = (acadapplication)marshal.getactiveobject("autocad.application");
acadpopupmenu mymenu = acadapp.menugroups.item(0).menus.add("我的菜单");
mymenu.addmenuitem(0, "直线", "_line");
mymenu.addmenuitem(1, "圆", "_circle");
mymenu.addseparator(2);
acadpopupmenu subm = mymenu.addsubmenu("", "子菜单");
subm.addmenuitem(0,"射线","xline");
mymenu.addmenuitem(4, "圆弧", "_arc");
mymenu.insertinmenubar(14);
想在“直线”按钮上添加事件，怎么弄啊？望高手指点一二啊，非常感谢！
