C# ToolStrip制作四边停靠浮动工具栏

这篇文章主要介绍了C# ToolStrip浮动工具栏的制作,可以上/下/左/右停靠，代码在下面

关于浮动工具条的制作其实阿捷给出的代码已经相当详细了:) 我这里主要给出重写的ToolStrip代码段，增加了三个ToolStripPanel代码如下: public partial class MyToolStrip : ToolStrip { public MyToolStrip() { InitializeComponent(); this.EndDrag += new EventHandler(MyToolStrip_EndDrag); this.SizeChanged += new EventHandler(MyToolStrip_SizeChanged); } #region 漂浮状态 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 漂浮实现 private void FloatWindow_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.FloatWindow == null) { return; } if (FloatWindow.HasCreated) { //主窗体位置 Point frmLoc = this.TopToolStripPanel.Parent.Location; //浮动工具条位置 Point toolBarLoc = FloatWindow.Location; if (toolBarLoc.Y - frmLoc.Y <= 0) //置于顶部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) //置于左边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; return; } if (toolBarLoc.X + FloatWindow.Width >= this.TopToolStripPanel.Parent.Width) //置于右边StripPanel { this.FloatWindow.Controls.Remove(this); this.RightToolStripPanel.SuspendLayout(); this.RightToolStripPanel.Controls.Add(this); this.Location = this.RightToolStripPanel.PointToClient(toolBarLoc); this.RightToolStripPanel.ResumeLayout(); this.FloatWindow.Dispose(); this.FloatWindow = null; return; } if (toolBarLoc.Y + FloatWindow.Height >= this.TopToolStripPanel.Parent.Height) //置于底部StripPanel { this.FloatWindow.Controls.Remove(this); this.BottomToolStripPanel.SuspendLayout(); this.BottomToolStripPanel.Controls.Add(this); this.Location = this.BottomToolStripPanel.PointToClient(toolBarLoc); this.BottomToolStripPanel.ResumeLayout(); this.FloatWindow.Dispose(); this.FloatWindow = null; return; } } } private void MyToolStrip_EndDrag(object sender, EventArgs e) { Point screenPt = Cursor.Position; Point clientPt = this.TopToolStripPanel.Parent.PointToClient(screenPt); //浮动区域 Rectangle floatArea = new Rectangle(32, 32, //我这里图标大小调整为32*32 this.TopToolStripPanel.Parent.Width - 2 * 32, this.TopToolStripPanel.Parent.Height - 2 * 32); if (floatArea.Contains(clientPt)) //判断移出时 { ToolStripFloatWindow fw = new ToolStripFloatWindow(); fw.Controls.Add(this); this.Left = 0; this.Top = 0; this.FloatWindow = fw; FloatWindow.LocationChanged += new EventHandler(FloatWindow_LocationChanged); fw.SetBounds(screenPt.X, screenPt.Y, this.ClientSize.Width, this.ClientSize.Height + 22); //22为窗体标题栏高度 fw.Show(); } } private void MyToolStrip_SizeChanged(object sender, EventArgs e) { if (this.isFloating) { this.FloatWindow.Width = this.ClientSize.Width; } } #endregion }
