listbox是否可以像菜单一样，让光标跟随鼠标走?

Question

鼠标进入Listbox后,鼠标指到哪,激活项的光标跟着指到那里.

Answer 1

在 lv的mousemove事件里 加代码

Answer 2

重写ListBox的WndProc,当鼠标移动时,给ListBox发送鼠标单击的事件消息. public partial class MyListBox : ListBox
    {
        [DllImport("user32.dll")]
        public static extern int SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam);        public MyListBox()
        {
            InitializeComponent();
        }        protected override void WndProc(ref Message m)
        {
            base.WndProc(ref m);            Console.WriteLine(m.Msg.ToString());            switch (m.Msg)
            {
                case 32:
                    SendMessage(this.Handle, 513, 0, 0);
                    break;
                default:
                    break;
            }
        }
    }
