關于浮動工具條的制作，阿捷寫了一篇很不錯的文章，見：//www.49028c.com/article/44272.htm
阿捷這個工具條浮動后只能在頂部停靠，基于此，我在這邊增加在左/右/底部停靠，停靠條件是浮動窗體緊貼或越過主窗體邊緣。
其實阿捷給出的代碼已經相當詳細了:) 我這里主要給出重寫的ToolStrip代碼段，增加了三個ToolStripPanel
#region 漂浮狀態
public ToolStripFloatWindow FloatWindow { get; set; }
private bool isFloating
{
get
{
return (FloatWindow != null);
}
}
public ToolStripPanel TopToolStripPanel { get; set; }
public ToolStripPanel BottomToolStripPanel { get; set; }
public ToolStripPanel LeftToolStripPanel { get; set; }
public ToolStripPanel RightToolStripPanel { get; set; }
#endregion
#region 漂浮實現
private void FloatWindow_LocationChanged(object sender, EventArgs e)
{
//當floatwindws的位置移動到 toolstrippanel中時，將this放置到 toolstripPanel上
if (this.FloatWindow == null)
{
return;
}
if (FloatWindow.HasCreated)
{
//主窗體位置
Point frmLoc = this.TopToolStripPanel.Parent.Location;
//浮動工具條位置
Point toolBarLoc = FloatWindow.Location;
if (toolBarLoc.Y - frmLoc.Y <= 0) //置于頂部StripPanel
{
this.FloatWindow.Controls.Remove(this);
this.TopToolStripPanel.SuspendLayout();
this.TopToolStripPanel.Controls.Add(this);
this.Location = this.TopToolStripPanel.PointToClient(toolBarLoc);
this.TopToolStripPanel.ResumeLayout();
this.FloatWindow.Dispose();
this.FloatWindow = null;
return;
}
if (toolBarLoc.X - frmLoc.X <= 0) //置于左邊StripPanel
{
this.FloatWindow.Controls.Remove(this);
this.LeftToolStripPanel.SuspendLayout();
this.LeftToolStripPanel.Controls.Add(this);
this.Location = this.LeftToolStripPanel.PointToClient(toolBarLoc);
this.LeftToolStripPanel.ResumeLayout();
this.FloatWindow.Dispose();
this.FloatWindow = null;
