浅析WINFORM工具条的重用实现

     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.

                }

                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.
