xtraTabControl 如何遍历每个选项卡 z

XtraTabHitInfo hi = tabPositionControl.CalcHitInfo(new Point(e.X, e.Y));
if (hi.HitTest == XtraTabHitTest.PageHeader)
{
    // 这段话就是根据坐标(x, y)判断是否点击了Tab Header。这个e.X跟e.Y可以从MouseMove事件参数e里面来这你应该知道吧？
  // 还可以通过XtraTabHitTest这个枚举值判断更多的情况。
}

private void xtraTabControl1_MouseMove(object sender, MouseEventArgs e)
        {

            XtraTabControl tabCtrl = sender as XtraTabControl;
            Point pt = MousePosition;              
            XtraTabHitInfo info = tabCtrl.CalcHitInfo(tabCtrl.PointToClient(pt));
            if (info.HitTest == XtraTabHitTest.PageHeader)
            {
                xtraTabControl1.SelectedTabPage = info.Page;
            }          
        }
