六 阴影效果鼠标左键移动窗口
1）引用API

2）定义鼠标事件
//窗体拖动 bool isMouseDown = false; //Point cwpt = new Point(); //当前窗体位置 //Point cmpt = new Point(); //当前鼠标的按下位置 private void sysSet_MouseDown(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { isMouseDown = true; //cwpt = this.Location; //cmpt = System.Windows.Forms.Control.MousePosition; } } private void sysSet_MouseUp(object sender, MouseEventArgs e) { //if (WindowState == FormWindowState.Normal) //{ // this.Location = cwpt; // this.pnlMax.BackgroundImage = global::Cnwin.Apps.Properties.Resources.max12; //} //else //{ // this.pnlMax.BackgroundImage = global::Cnwin.Apps.Properties.Resources.min16w; //} isMouseDown = false; } private void sysSet_MouseMove(object sender, MouseEventArgs e) { //int rangeX = 0, rangeY = 0; //计算当前鼠标光标的位移，让窗体进行相同大小的位移 //if (isMouseDown) //{ // Point pt = System.Windows.Forms.Control.MousePosition; // rangeX = cmpt.X - pt.X; // rangeY = cmpt.Y - pt.Y; // this.Location = new Point(cwpt.X - rangeX, cwpt.Y - rangeY); //} //常量 int WM_SYSCOMMAND = 0x0112; //窗体移动 int SC_MOVE = 0xF010; int HTCAPTION = 0x0002; ReleaseCapture(); SendMessage(this.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0); if (WindowState == FormWindowState.Normal && isMouseDown) { this.pnlMax.BackgroundImage = global::Cnwin.Apps.Properties.Resources.max16; } else if (isMouseDown) { this.pnlMax.BackgroundImage = global::Cnwin.Apps.Properties.Resources.max12; } }
