浅析WINFORM工具条的重用实现

摘要: 一直以来,我都想看看别人家的工具栏重用(图1)到底是如何实现的,但在网上搜索了很久都没有找到过,即使找到一些程序,要么就是把这个工具栏写在具体的画面(图2),要么就是没有源代码的, 我在想,是否别人也有这个需求呢? 于是我决定把我自己的程序代码帖出来,一来可以分享给到需要的朋友,二来,希望有大侠经过,指点一二.

(图1)

 

(图2).

对于图2, 当然好实现了, 只是对当前画面的功能实现. 相当于单独画面的一个按钮而已.

现在,我们主要讲一下图1的实现方法.

在首先,在讲工具栏之前,讲一下菜单栏的实现(图3),在设计的时候,我们的菜单都是没有权限的. 通过在数据库里设定权限做了控制.

(图3)

首先在frmMain_Load的时候,加载下面的代码,这里主要是调用递归函数.

            MenuStrip ms = (MenuStrip)this.Controls["menuStrip1"];            ArrayList arr = new ArrayList();            dsright = C_BaseInfo.UserRight(frmLogin.C_UserInfo);            GetMenuAllName(arr, null, 0, ms);//调用递归函数

有一些每个用户都需要的菜单就直接置true了,如更改密码,报表工具等.(具体的报表权限还有地方控制了的.)

        private void GetMenuAllName(ArrayList arr, ToolStripMenuItem tsmi, int level, MenuStrip ms)        {            if (level == 0)//一级菜单            {                for (int i = 0; i < ms.Items.Count; i++)                {                    ToolStripMenuItem item = (ToolStripMenuItem)ms.Items[i];                    string Group = item.Text + ";" + level.ToString();//item.Text 菜单项的名字  level 此菜单的的级别                    arr.Add(Group);                    // item.Enabled = false;                    GetMenuAllName(arr, item, level + 1, ms);                }            }            else//二级菜单            {                if (tsmi != null && tsmi.DropDownItems.Count > 0)                {                    for (int i = 0; i < tsmi.DropDownItems.Count; i++)                    {                        if (tsmi.DropDownItems[i].GetType().ToString() != "System.Windows.Forms.ToolStripSeparator")                        {                            if (tsmi.Name != "mnuTools" && tsmi.Name != "mnuControl" && tsmi.Name != "mnuWindows" && tsmi.Name != "mnuSystem")                            {                                ToolStripMenuItem item = (ToolStripMenuItem)tsmi.DropDownItems[i];                                string Group = item.Text + ";" + level.ToString();                                arr.Add(Group);                                //item.Enabled = false;                                if (item.Name == "mnuChgPwd")                                {                                    item.Enabled = true;                                }                                if (dsright.Tables[0].Rows.Count > 0)                                {                                    for (int j = 0; j < dsright.Tables[0].Rows.Count; j++)                                    {                                        if (item.Name == dsright.Tables[0].Rows[j]["MenuName"].ToString())                                        {                                            item.Enabled = true;                                        }                                        //ToolStripMenuItem a = (ToolStripMenuItem)dsright.Tables[0].Rows[j]["MenuName"].ToString();                                        ////a.Enabled = true;                                        //object a= (this.Controls.Find(dsright.Tables[0].Rows[j]["MenuName"].ToString(), true)[0]);                                        //ToolStripMenuItem b = (ToolStripMenuItem)a;                                    }                                }                                GetMenuAllName(arr, item, level + 1, ms);                            }                        }                    }                }            }        }

首先看一下, 工具栏按钮的定义.

具体到某一个画面时,它们的新增,删除,修改的权限时又做了控制.

 for (int i = 0; i < pParentWin.dsright.Tables[0].Rows.Count; i++)            {                if (pParentWin.dsright.Tables[0].Rows[i]["FormName"].ToString() == this.Name)                {                    CanIns = Convert.ToBoolean(pParentWin.dsright.Tables[0].Rows[i]["CanIns"]);                    CanUpd = Convert.ToBoolean(pParentWin.dsright.Tables[0].Rows[i]["CanUpd"]);                    CanDel = Convert.ToBoolean(pParentWin.dsright.Tables[0].Rows[i]["CanDel"]);                }            }            InitializeTools(1);  // 这里是初始化

// 初始化分为多种情况.

  private void InitializeTools(int Type)        {            if (Type == 0) //主窗体加载时,主菜单完全不可用            {                pParentWin.toolStrip1.Enabled = false;                ToolsStatue = 0;            }            else if (Type == 1) //加载子窗体后或点预备查询后，查找 预备查询 新增 打印可用其余都不可用            {                pParentWin.toolStrip1.Enabled = true;                pParentWin.toolStripAddNew.Enabled = true;                pParentWin.toolStripPreSearch.Enabled = true;                pParentWin.toolStripSearch.Enabled = true;                pParentWin.toolStripPrint.Enabled = true;                pParentWin.toolStripFirst.Enabled = false;                pParentWin.toolStripPre.Enabled = false;                pParentWin.toolStripNext.Enabled = false;                pParentWin.toolStripLast.Enabled = false;                pParentWin.toolStripSave.Enabled = false;                pParentWin.toolStripCopy.Enabled = false;                pParentWin.toolStripDelete.Enabled = false;                if (CanIns == false)                {                    pParentWin.toolStripAddNew.Enabled = false; //新增按钮失效                }                if (CanUpd == false)                {                    pParentWin.toolStripSave.Enabled = false;  //保存按钮失效                }                if (CanDel == false)                {                    pParentWin.toolStripDelete.Enabled = false;  //删除按钮失效                }                ToolsStatue = 1;            }            else if (Type == 2)//查询有结果后及保存后，所有工具条可用，如查询无结果，工具条状态为1            {                pParentWin.toolStrip1.Enabled = true;                pParentWin.toolStripAddNew.Enabled = true;                pParentWin.toolStripPreSearch.Enabled = true;                pParentWin.toolStripSearch.Enabled = true;                pParentWin.toolStripPrint.Enabled = true;                pParentWin.toolStripFirst.Enabled = true;                pParentWin.toolStripPre.Enabled = true;                pParentWin.toolStripNext.Enabled = true;                pParentWin.toolStripLast.Enabled = true;                pParentWin.toolStripSave.Enabled = true;                pParentWin.toolStripCopy.Enabled = true;                pParentWin.toolStripDelete.Enabled = true;                if (CanIns == false)                {                    pParentWin.toolStripAddNew.Enabled = false; //新增按钮失效                }                if (CanUpd == false)                {                    pParentWin.toolStripSave.Enabled = false;  //保存按钮失效                }                if (CanDel == false)                {                    pParentWin.toolStripDelete.Enabled = false;  //删除按钮失效                }                ToolsStatue = 2;            }            else if (Type == 3)//点新增后，除新增不可用。其余工具条全部可用            {                pParentWin.toolStrip1.Enabled = true;                pParentWin.toolStripAddNew.Enabled = false;                pParentWin.toolStripPreSearch.Enabled = true;                pParentWin.toolStripSearch.Enabled = true;                pParentWin.toolStripPrint.Enabled = true;                pParentWin.toolStripFirst.Enabled = true;                pParentWin.toolStripPre.Enabled = true;                pParentWin.toolStripNext.Enabled = true;                pParentWin.toolStripLast.Enabled = true;                pParentWin.toolStripSave.Enabled = true;                pParentWin.toolStripCopy.Enabled = true;                pParentWin.toolStripDelete.Enabled = true;                if (CanIns == false)                {                    pParentWin.toolStripAddNew.Enabled = false; //新增按钮失效                }                if (CanUpd == false)                {                    pParentWin.toolStripSave.Enabled = false;  //保存按钮失效                }                if (CanDel == false)                {                    pParentWin.toolStripDelete.Enabled = false;  //删除按钮失效                }                ToolsStatue = 3;            }        }

这里基本上就差不多了. 但如果打开多个画面之间,按钮是需要回到当时的状态的.

        private void frm_Activated(object sender, EventArgs e)        {            //自定义父窗口的工具栏            InitializeToolsEvent(1);            InitializeTools(ToolsStatue);          }        private void frm_Deactivate(object sender, EventArgs e)        {            //自定义父窗口的工具栏            InitializeToolsEvent(0);        }

InitializeTools(ToolsStatue) 就是当时的状态了. 而InitializeToolsEvent就是注册和释放工具栏按钮了.

 private void InitializeToolsEvent(int Type)        {            if (Type == 1) //得到焦点            {                pParentWin.toolStripSearch.Click += new EventHandler(this.Search);                pParentWin.toolStripPreSearch.Click += new EventHandler(this.PreSearch);                pParentWin.toolStripAddNew.Click += new EventHandler(this.AddNew);                pParentWin.toolStripSave.Click += new EventHandler(this.Save);                pParentWin.toolStripFirst.Click += new EventHandler(this.First);                pParentWin.toolStripPre.Click += new EventHandler(this.Pre);                pParentWin.toolStripNext.Click += new EventHandler(this.Next);                pParentWin.toolStripLast.Click += new EventHandler(this.Last);                pParentWin.toolStripDelete.Click += new EventHandler(this.Delete);                pParentWin.toolStripCopy.Click += new EventHandler(this.Copy);                pParentWin.toolStripPrint.Click += new EventHandler(this.Print);            }            else            {                pParentWin.toolStripSearch.Click -= new EventHandler(this.Search);                pParentWin.toolStripPreSearch.Click -= new EventHandler(this.PreSearch);                pParentWin.toolStripAddNew.Click -= new EventHandler(this.AddNew);                pParentWin.toolStripSave.Click -= new EventHandler(this.Save);                pParentWin.toolStripFirst.Click -= new EventHandler(this.First);                pParentWin.toolStripPre.Click -= new EventHandler(this.Pre);                pParentWin.toolStripNext.Click -= new EventHandler(this.Next);                pParentWin.toolStripLast.Click -= new EventHandler(this.Last);                pParentWin.toolStripDelete.Click -= new EventHandler(this.Delete);                pParentWin.toolStripCopy.Click -= new EventHandler(this.Copy);                pParentWin.toolStripPrint.Click -= new EventHandler(this.Print);            }        }

然后这里再对每一个功能进行重写就可以了.

想法很简单, 基本代码也有了. 希望对大家有用,如有不明白的地方,请留言, 有更好的实现方法也请指点一二.  本人不胜感激.
