C# ToolStrip浮动工具栏 C# ToolStrip制作四边停靠浮动工具栏

人气:0
想了解C# ToolStrip制作四边停靠浮动工具栏的相关内容吗,在本文为您仔细讲解C# ToolStrip浮动工具栏的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:ToolStrip,浮动工具栏,下面大家一起来学习吧。

关于浮动工具条的制作,阿捷写了一篇很不错的文章,见:
阿捷这个工具条浮动后只能在顶部停靠,基于此,我在这边增加在左/右/底部停靠,停靠条件是浮动窗体紧贴或越过主窗体边缘。

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

复制代码 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
