如果叠加button悬浮在winform?

Question

      winform中两个panel,一个splitter,动态添加button,画在splitter上面，随着splitter动而动，浮在经过的控件上面，见过这样子的，不知道怎么搞的？

Answer 1

    public partial class Form1 : Form
    {
        Button btn1;
        public Form1()
        {
            InitializeComponent();
            btn1 = new Button();
            btn1.Size = new Size(60, 27);
            btn1.Text = "Test";
            btn1.Location = new Point(this.splitter1.Left, 100);
           
            this.Controls.Add(btn1);            this.Controls.SetChildIndex(btn1, 0);
        }        private void splitter1_SplitterMoved(object sender, SplitterEventArgs e)
        {
            if(this.btn1!=null) this.btn1.Left = this.splitter1.Left;
        }
    }

Answer 2

            this.splitter1.SplitterMoved += new System.Windows.Forms.SplitterEventHandler(this.splitter1_SplitterMoved);
