C# ArcEngine 工具条拖放
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; ??????????????????? } ??????????????? } ??????????? } ??????? }
