這篇文章主要介紹了C#實現(xiàn)Winform無邊框移動的方法,涉及C#針對WinForm窗口操作的相關技巧,具有一定參考借鑒價值,需要的朋友可以參考下
本文實例講述了C#實現(xiàn)Winform無邊框移動的方法。分享給大家供大家參考。具體如下:
- const int HTLEFT = 10;
- const int HTRIGHT = 11;
- const int HTTOP = 12;
- const int HTTOPLEFT = 13;
- const int HTTOPRIGHT = 14;
- const int HTBOTTOM = 15;
- const int HTBOTTOMLEFT = 0x10;
- const int HTBOTTOMRIGHT = 17;
- protected override void WndProc(ref Message m)
- {
- switch (m.Msg)
- {
- 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)HTTOPLEFT;
- else if (vPoint.Y >= ClientSize.Height - 5)
- m.Result = (IntPtr)HTBOTTOMLEFT;
- else m.Result = (IntPtr)HTLEFT;
- else if (vPoint.X >= ClientSize.Width - 5)
- if (vPoint.Y <= 5)
- m.Result = (IntPtr)HTTOPRIGHT;
- else if (vPoint.Y >= ClientSize.Height - 5)
- m.Result = (IntPtr)HTBOTTOMRIGHT;
- else m.Result = (IntPtr)HTRIGHT;
- else if (vPoint.Y <= 5)
- m.Result = (IntPtr)HTTOP;
- else if (vPoint.Y >= ClientSize.Height - 5)
- m.Result = (IntPtr)HTBOTTOM;
- break;
- case 0x0201://鼠標左鍵按下的消息
- m.Msg = 0x00A1;//更改消息為非客戶區(qū)按下鼠標
- m.LParam = IntPtr.Zero;//默認值
- m.WParam = new IntPtr(2);//鼠標放在標題欄內(nèi)
- base.WndProc(ref m);
- break;
- default:
- base.WndProc(ref m);
- break;
- }
- }
希望本文所述對大家的C#程序設計有所幫助。
