因为去掉了边框 移动和调整大小都用不了了，可以调用WIN32的API来实现
1.定义必须常量
const int Guying_HTLEFT = 10; const int Guying_HTRIGHT = 11; const int Guying_HTTOP = 12; const int Guying_HTTOPLEFT = 13; const int Guying_HTTOPRIGHT = 14; const int Guying_HTBOTTOM = 15; const int Guying_HTBOTTOMLEFT = 0x10; const int Guying_HTBOTTOMRIGHT = 17;
2.重写系统函数
protected override void WndProc(ref Message m) { switch (m.Msg) { //更改窗口大小的现实 case 0x0084: base.WndProc(ref m); Point vPoint = new Point((int)m.LParam & 0xFFFF, (int)m.LParam >> 16 & 0xFFFF); vPoint = PointToClient(vPoint); if (vPoint.X <= 5) if (vPoint.Y <= 5) m.Result = (IntPtr)Guying_HTTOPLEFT; else if (vPoint.Y >= ClientSize.Height - 5) m.Result = (IntPtr)Guying_HTBOTTOMLEFT; else m.Result = (IntPtr)Guying_HTLEFT; else if (vPoint.X >= ClientSize.Width - 5) if (vPoint.Y <= 5) m.Result = (IntPtr)Guying_HTTOPRIGHT; else if (vPoint.Y >= ClientSize.Height - 5) m.Result = (IntPtr)Guying_HTBOTTOMRIGHT; else m.Result = (IntPtr)Guying_HTRIGHT; else if (vPoint.Y <= 5) m.Result = (IntPtr)Guying_HTTOP; else if (vPoint.Y >= ClientSize.Height - 5) m.Result = (IntPtr)Guying_HTBOTTOM; break; //移动窗口的实现 case 0x0201: //鼠标左键按下的消息 m.Msg = 0x00A1; //更改消息为非客户区按下鼠标 m.LParam = IntPtr.Zero; //默认值 m.WParam = new IntPtr(2);//鼠标放在标题栏内 base.WndProc(ref m); break; default: base.WndProc(ref m); break; } }
