InitializeComponent();
BdmsInterface.MenuItem[] menus = new BdmsInterface.MenuItem[]{
new BdmsInterface.MenuItem("系统","S"),
new BdmsInterface. MenuItem("项目","X"),
new BdmsInterface.MenuItem("工具","T")
};
menus[0].Items.Add(new BdmsInterface.MenuItem("退出", "X"));
this.menuMain.ItemsSource = menus;
}
}
运行后，出现主菜单（能看见“系统”一级的菜单）
其中“系统”后面有个三角符号，表示子菜单内容也有了，但是点击“系统”后，没有子菜单弹出，求解?
