如何显示 CheckedListBoxControl 项的工具提示

效果如图所示，CheckedListBoxControl 的项内容并不能完整显示，所以需要加一个工具提示。

代码如下：

        private void ToolTipController1_GetActiveObjectInfo(object sender, DevExpress.Utils.ToolTipControllerGetActiveObjectInfoEventArgs e)
        {
            if (e.SelectedControl == checkedListBoxControl1)
            {
                BaseListBoxViewInfo vi = checkedListBoxControl1.GetViewInfo() as BaseListBoxViewInfo;
                CheckedItemInfo itemInfo = vi.GetItemInfoByPoint(e.ControlMousePosition) as CheckedItemInfo;

                if(itemInfo != null && itemInfo.CheckArgs.CheckState == CheckState.Checked)
                {
                    e.Info = new ToolTipControlInfo() { ToolTipType = ToolTipType.SuperTip, Object = itemInfo };
                    var itemTreeListToolTip = new SuperToolTip();
                    SuperToolTipSetupArgs args = new SuperToolTipSetupArgs();
                    args.Title.Text = "Title";
                    args.Contents.Text = itemInfo.Text;
                    args.Contents.Image = Properties.Resources.Image;
                    itemTreeListToolTip.Setup(args);
                    e.Info.SuperTip = itemTreeListToolTip;
                }
            }
        }
