易采站长站为您分析C#实现Winform无边框移动的方法,涉及C#针对WinForm窗口操作的相关技巧,具有一定参考借鉴价值,需要的朋友可以参考下
本文实例讲述了C#实现Winform无边框移动的方法。。具体如下：
- 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; }
