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

1. 控件dockpanel中提供了幾個可用的類, 重要的有兩個, 一是DockPanel, 一是DockContent, 

    DockPanel是從panel繼承出來的, 用於提供可浮動的dock的子窗口進行浮動和dock的場所, 
    DockContent是從form類中繼承出來的, 用於提供可浮動的窗口基類. 就是說: DockContent對象可以在DockPanel對象中任意貼邊, 浮動, TAB化等.

4. 將dockPanel拖到窗體Form1上，設置Dock屬性，我設置的是：Fill。窗體屬性IsMdiContainer:True。
5.  在代碼中修改窗體繼承於DockContent。           public partial class Form2 : DockContent
6. 在主窗體中：

   public partial class Form1 : DockContent
       {
           //子窗體
           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);
               //窗體Form2添加到主窗體左邊緣
               frm.DockTo(this.dockPanel1,DockStyle.Left);
           }
   }

    

7. 在主窗體中添加右鍵事件，設置dockPanel的contentMenuScrip為拖拽的menuscrip,窗體添加

    /// <summary>
           /// 關閉所有窗體
           /// </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>
           /// 關閉其他窗體
           /// </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>
           /// 找到窗體
           /// </summary>
           /// <param name="text"></param>

           private DockContent FindDocument(string text)

                   foreach (Form form in MdiChildren)
                   {

                   foreach (DockContent  content in dockPanel1.Documents)
