XtraTabPage右键菜单(关闭当前页、关闭其它页、所有关闭的实现)

实现的需求:

用户习惯是一个不可忽略的东西，默认这版的dx的tab也木有右键操作，但用户习惯操作如浏览器都有右键关闭功能，故这里实现先dx的该功能

技术实现:

(1)在winform的相应控件内，拖入以下dx的控件

(2)初始化右键的菜单项

         private void InitPopMenu()
         {
             BarButtonItem barItemCurrent = new BarButtonItem
             {
                 Name = "barItemCurrent",
                 Caption = "关闭当前"
             };
             barItemCurrent.ItemClick -= BarItemCloseCurrentClick;
             barItemCurrent.ItemClick += BarItemCloseCurrentClick;
             BarButtonItem barItemOther = new BarButtonItem
             {
                 Name = "barItemOther",
                 Caption = "关闭其他"
             };
             barItemOther.ItemClick -= BarItemCloseOtherClick;
             barItemOther.ItemClick += BarItemCloseOtherClick;
             BarButtonItem barItemAll = new BarButtonItem
             {
                 Name = "barItemAll",
                 Caption = "关闭全部"
             };
             barItemAll.ItemClick -= BarItemCloseAllClick;
             barItemAll.ItemClick += BarItemCloseAllClick;
             popupMenu.LinksPersistInfo.AddRange(new LinkPersistInfo[] { new LinkPersistInfo(barItemCurrent), new LinkPersistInfo(barItemOther), new LinkPersistInfo(barItemAll) });
         }

(3)绑定tab页的右键

        private void XtraTabControlMouseUp(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Right)
            {
                XtraTabControl tabCtrl = sender as XtraTabControl;
                var pt = e.Location;
                if (tabCtrl != null)
                {
                    XtraTabHitInfo info = tabCtrl.CalcHitInfo(pt);
                    if (info.HitTest == XtraTabHitTest.PageHeader)
                    {
                        popupMenu.ShowPopup(MousePosition);
                    }
                }
            }
        }

(4).效果图如下:

ok，到此右键菜单完成，建议封装一个继承与XtraTabControl的用户自定义控件,在此用户控件内封装好右键菜单。

下一次，讲一下tab页的拖拽，这里透漏一下，实际项目里遇到了dx里tab内关闭按钮的小叉叉跟拖拽的鼠标左键拖拽代码冲突，就是说点击小叉叉不能关闭了。好在后来找到了解决方法~
