C# 粘连窗体效果(窗体连动 类似千千静听播放器的)

两个窗体分别是FormMain  FormList

 

第1个窗体：FormMain  ：

 

public partial class FormMain : Form { FormList formlist=null ; public FormMain() { FormMain fm = this; formlist = new FormList(ref fm);//传到第2个窗体去 InitializeComponent(); } public bool isLinked ; private void FormMain_Load(object sender, EventArgs e) { Application.DoEvents(); formlist.Show(); isLinked = false; formlist.Left = this.Left + this.Width+20;//开始分开点，也可以不分开不要20 formlist.Top = this.Top; this.Show(); } private void FormMain_LocationChanged(object sender, EventArgs e) { int fltop = formlist.flTop; if (formlist == null) { return; } // 一起移2个窗体 if (isLinked || Math.Abs(this.Left + this.Width - formlist.Left) <= 15) { formlist.Left = this.Left + this.Width; // formlist.Top = this.Top; formlist.Top = this.Top - (fltop); isLinked = true; return; } isLinked = false; } }

第2个窗体：FormList

 

public partial class FormList : Form { public FormList() { InitializeComponent(); // ClassCommon.com_FormList = this; } public FormList(ref FormMain fm) { _fm = fm;//引用FormMain InitializeComponent(); } FormMain _fm = null; public int flTop = 0;//记录两个窗体高度差 private void FormList_LocationChanged(object sender, EventArgs e) { this.Text = this.Location.ToString(); //if (_fm == null) { return; } flTop = _fm.Top - this.Top; if (Math.Abs(_fm.Left + _fm.Width - this.Left) <= 15) { this.Left = _fm.Left + _fm.Width; _fm.isLinked = true; } else { _fm.isLinked = false; } } }

 

 

哈哈运行是不是很酷。。。。

别急，要千千静听那样就要设置无边框窗体，要实现拖动

OK ，用下面的加到2个窗体类里：

 

 

   #region "拖动窗体"
        private bool moveFlag = false;
        private int x = 0;
        private int y = 0;

        protected override void OnMouseMove(System.Windows.Forms.MouseEventArgs e)
        {
            if (moveFlag && (e.Button == MouseButtons.Left))
                this.SetBounds(Left + e.X - x, Top + e.Y - y, this.Width, this.Height);
            base.OnMouseMove(e);
        }

        protected override void OnMouseDown(System.Windows.Forms.MouseEventArgs e)
        {
            if (!moveFlag && e.Clicks >= 1)
                moveFlag = true;
            x = e.X;
            y = e.Y;
            base.OnMouseDown(e);
        }

        protected override void OnMouseUp(System.Windows.Forms.MouseEventArgs e)
        {
            if (moveFlag)
                moveFlag = false;
            base.OnMouseUp(e);
        }

        #endregion

自己把界面设计好看点，说不定你能比它还炫呵。

希望对大家有用。
