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，
