学习winform第三方界面weiFenLuo.winFormsUI.Docking.dll

1. 控件dockpanel中提供了几个可用的类, 重要的有两个, 一是DockPanel, 一是DockContent, 

      DockPanel是从panel继承出来的, 用于提供可浮动的dock的子窗口进行浮动和dock的场所, 
    DockContent是从form类中继承出来的, 用于提供可浮动的窗口基类. 就是说: DockContent对象可以在DockPanel对象中任意贴边, 浮动, TAB化等.

4. 将dockPanel拖到窗体Form1上，设置Dock属性，我设置的是：Fill。窗体属性IsMdiContainer:True。
5.  在代码中修改窗体继承于DockContent。           public partial class Form2 : DockContent
6. 在主窗体中：

   public partial class Form1 : DockContent
       {
           //子窗体
           private FrmCustomer frmCustomer = new FrmCustomer();
           private b_employee employee = new b_employee ();
   
           public Form1()
           {
               InitializeComponent();
               frmCustomer.Show(this.dockPanel1);
               employee.Show(this.dockPanel1);
               System.Threading.Thread.Sleep(50);
           }
   
           private void Form1_Load(object sender, EventArgs e)
           {
               Form2 frm = new Form2();
               frm.Show(this.dockPanel1);
               //窗体Form2添加到主窗体左边缘
               frm.DockTo(this.dockPanel1,DockStyle.Left);
           }
   }

7. 在主窗体中添加右键事件，设置dockPanel的contentMenuScrip为拖拽的menuscrip,窗体添加

    /// <summary>
           /// 关闭所有窗体
           /// </summary>
           /// <param name="sender"></param>
           /// <param name="e"></param>
           private void menu_Window_CloseAll_Click(object sender, EventArgs e)
           {
               CloseAllDocuments();
           }
   
           public void CloseAllDocuments()
           {
               if (dockPanel1.DocumentStyle==DocumentStyle.SystemMdi)
               {
                   foreach (Form form in MdiChildren)
                   {
                        form.Close();
                   }
               }
                   else
                   {
                       IDockContent[] documents=dockPanel1.DocumentsToArray();
                       foreach (IDockContent content in documents)
                       {
                           content.DockHandler.Close();
                       }
                   }
               }
           /// <summary>
           /// 关闭其他窗体
           /// </summary>
           /// <param name="sender"></param>
           /// <param name="e"></param>
           private void menu_Window_CloseOther_Click(object sender, EventArgs e)
           {
               if (dockPanel1.DocumentStyle == DocumentStyle.SystemMdi)
               {
                   Form activeMdi = ActiveMdiChild;
                   foreach (Form form in MdiChildren)
                   {
                       if (form != activeMdi)
                       {
                           form.Close();
                       }
                   }
               }
               else 
               {
                   foreach (IDockContent document in dockPanel1.DocumentsToArray())
                   {
                       if (!document.DockHandler.IsActivated)
                       {
                           document.DockHandler.Close();
                       }
                   }
               }
           }
   
           /// <summary>
           /// 找到窗体
           /// </summary>
           /// <param name="text"></param>

           private DockContent FindDocument(string text) 
           {
               if (dockPanel1.DocumentStyle == DocumentStyle.SystemMdi)

                   foreach (DockContent  content in dockPanel1.Documents)
