利用UtilityLibrary.dll WeifenLuo.WinFormsUI.Docking.dll控件创建工具栏效果

需求：

1.四个窗体 MainToolWindow（左边工具栏），MainForom（主窗体），form1（常规窗体）

form2（测试窗体）

2. 需要两个文件

UtilityLibrary.dll

WeifenLuo.WinFormsUI.Docking.dll

具体步骤如下：

1.设置MainForm的ISMdiContainer为True；

在MainForm中引用WeifenLuo.WinFormsUI.Docking.dll，然后在工具栏点选项卡，

添加控件dockPanel1拖至窗体，

设置DOCK为Fill

RightToLeftLayOut为True，

2.在MianToolWindow引用UtilityLibrary.dll，然后在工具栏点选项卡，

添加控件outlookBar1至窗体，再拖一个ImageList1，在Images里加入图片

具体代码如下：

MainForm.cs

public partial class MainForm : Form 
    { 
        #region 属性字段 
        private MainToolWindow mainToolWin = new MainToolWindow(); 
        #endregion

 

        public MainForm() 
        { 
            InitializeComponent(); 
            mainToolWin.Show(this.dockPanel1, DockState.DockLeft); 
        }

private DockContent FindDocument(string text) 
        { 
            if (dockPanel1.DocumentStyle == DocumentStyle.SystemMdi) 
            { 
                foreach (Form form in MdiChildren) 
                { 
                    if (form.Text == text) 
                    { 
                        return form as DockContent; 
                    } 
                }

                return null; 
            } 
            else 
            { 
                foreach (DockContent content in dockPanel1.Documents) 
                { 
                    if (content.DockHandler.TabText == text) 
                    { 
                        return content; 
                    } 
                }

                return null; 
            } 
        }

        public DockContent ShowContent(string caption, Type formType) 
        { 
            DockContent frm = FindDocument(caption); 
            if (frm == null) 
            { 
                frm = Activator.CreateInstance(formType) as DockContent; 
                frm.DockHandler.TabText = caption; 
                frm.Show(dockPanel1); 
            } 
            frm.Show(dockPanel1, DockState.Document); 
            frm.BringToFront(); 
            return frm; 
        }

}

MainToolWindow.cs

    public partial class MainToolWindow : DockContent 
    { 
        
        public MainToolWindow() 
        { 
            InitializeComponent(); 
        } 

        private void Form2_Load(object sender, EventArgs e) 
        { 
            setBase.Items.Add(new OutlookBarItem("常规",0)); 
            setBase.Items.Add(new OutlookBarItem("测试",0)); 
            outlookBar1.ItemClicked += new OutlookBarItemClickedHandler(OnOutlookBarItemClicked); 
           this.panel1.Controls.AddRange(new Control[] { outlookBar1 }); 
        }

        private void OnOutlookBarItemClicked(OutlookBarBand band, OutlookBarItem item) 
        { 
            switch (item.Text) 
            { 
                case "常规": 
                    { 
                        Form1.getinstance(DockPanel); 
                        break; 
                    } 
                case "测试": 
                    { 
                        Form2.getinstance(DockPanel); 
                        break; 
                    } 
                    default: 
                    break; 
            } 
        } 
    }

Fom1.cs的代码：

public partial class Form1 : DockContent 
    { 
        public Form1() 
        { 
            InitializeComponent(); 
        }

        private static Form1 _initialize = null;

        public static Form1 getinstance(DockPanel p) 
        { 
            if (_initialize == null || _initialize.IsDisposed) 
            { 
                _initialize = new Form1(); 
            } 
            _initialize.Show(p); 
            _initialize.Activate();

            return _initialize; 
        } 
    }

form2同Form1，
