如何实现WinForms窗体隐藏

如QQ程序，窗体在桌面边界失去焦点时,窗体自动隐藏到桌面边缘，当鼠标移动到隐藏的窗体上时，窗体又会显示出来，可以用以下方法实现:

// 当窗体的位置发生改变时，定位窗体的位置 internal AnchorStyles StopAanhor = AnchorStyles.None; private void mStopAnhor() { if(this.Top <= 0 && this.Left <= 0) { StopAanhor = AnchorStyles.None; } else if (this.Top <= 0) { StopAanhor = AnchorStyles.Top; } else if (this.Left <= 0) { StopAanhor = AnchorStyles.Left; } else if (this.Left >= Screen.PrimaryScreen.Bounds.Width - this.Width) { StopAanhor = AnchorStyles.Right; } else if (this.Top >= Screen.PrimaryScreen.Bounds.Height - this.Height) { StopAanhor = AnchorStyles.Bottom; } else { StopAanhor = AnchorStyles.None; } } // 当窗体的位置改变时 private void MainForm_LocationChanged(object sender, EventArgs e) { this.mStopAnhor(); } ///

/// 时间控件，控制窗体的坐标 ///

/// /// private void timer1_Tick(object sender, EventArgs e) { if (this.Bounds.Contains(Cursor.Position)) { switch (this.StopAanhor) { case AnchorStyles.Top: //窗体在最上方隐藏时，鼠标接触自动出现 this.Location = new Point(this.Location.X, 0); break; //窗体在最左方隐藏时，鼠标接触自动出现 case AnchorStyles.Left: this.Location = new Point(0, this.Location.Y); break; //窗体在最右方隐藏时，鼠标接触自动出现 case AnchorStyles.Right: this.Location = new Point(Screen.PrimaryScreen.Bounds.Width - this.Width, this.Location.Y); break; } } else { //窗体隐藏时在靠近边界的一侧边会出现2像素原因：感应鼠标，同时2像素不会影响用户视线 switch (this.StopAanhor) { //窗体在顶部时时，隐藏在顶部，底部边界出现2像素 case AnchorStyles.Top: this.Location = new Point(this.Location.X, (this.Height - 2) * (-1)); break; //窗体在最左边时时，隐藏在左边，右边边界出现2像素 case AnchorStyles.Left: this.Location = new Point((-1) * (this.Width - 2), this.Location.Y); break; //窗体在最右边时时，隐藏在右边，左边边界出现2像素 case AnchorStyles.Right: this.Location = new Point(Screen.PrimaryScreen.Bounds.Width - 2, this.Location.Y); break; } } }
