C# ArcEngine 工具条拖放

实现工具条拖放：

private ToolStripPanel tsPanel;   //定义全局变量，定义一个工具条容器，存放拖动出来的工具条

在窗体加载时设置属性（初始化的构造函数中也可以）：

 FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedToolWindow;             ShowIcon = false;             ShowInTaskbar = false;             TopMost = true;

private FloatToolBarForm floatForm;

public FloatToolBarForm FloatForm()         {             get { return floatForm; }             set             {                 floatForm = value;                 if (floatForm != null)                 {                     floatForm.LocationChanged += new EventHandler(FloatToolBarForm_FormClosing);                     floatForm.FormClosing += new FormClosingEventHandler(FloatToolBarForm_FormClosing);                 }             }         }         private void FloatToolBarForm_FormClosing(object sender, FormClosingEventArgs e)         {             e.Cancel = true;         }         private void FloatToolBarForm_LocationChanged(object sender, EventArgs e)         {             //当floatwindws的位置移动到toolstrippanel中时，将this放置到 toolstripPanel上             if (this.floatForm == null)             {                 return;             }             else             {                 if (floatForm.HasCreated)                 {                     Point currentPt = new Point(floatForm.Location.X, floatForm.Location.Y);                     Point minPt = this.tsPanel.PointToScreen(tsPanel.Location);                     Point maxPt;                     if (this.tsPanel.Height <= 20)                     {                         maxPt = new Point(minPt.X + this.tsPanel.Width, minPt.Y + 20);                     }                     else                     {                         maxPt = new Point(minPt.X + this.tsPanel.Width, minPt.Y + this.tsPanel.Height);                     }                     if ((currentPt.X > minPt.X) && (currentPt.X < maxPt.X) && (currentPt.Y > minPt.Y - 25) && (currentPt.Y < maxPt.Y - 25))                     {                         this.floatForm.Controls.Remove(this);                         this.tsPanel.SuspendLayout();                         this.tsPanel.Controls.Add(this);                         this.Location = this.tsPanel.PointToClient(currentPt);                         this.tsPanel.ResumeLayout();                         this.floatForm.Dispose();                         this.floatForm = null;                     }                 }             }         }
