这篇文章主要介绍了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。分享给大家供大家参考。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;
- }
- }
希望本文所述对大家的C#程序设计有所帮助。
