C#实现Winform无边框移动的方法
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：
constintHTLEFT=10;
constintHTRIGHT=11;
constintHTTOP=12;
constintHTTOPLEFT=13;
constintHTTOPRIGHT=14;
constintHTBOTTOM=15;
constintHTBOTTOMLEFT=0x10;
constintHTBOTTOMRIGHT=17;
protectedoverridevoidWndProc(refMessagem)
{
switch(m.Msg)
{
case0x0084:
base.WndProc(refm);
PointvPoint=newPoint((int)m.LParam&0xFFFF,
(int)m.LParam>>16&0xFFFF);
vPoint=PointToClient(vPoint);
if(vPoint.X<=5)
if(vPoint.Y<=5)
m.Result=(IntPtr)HTTOPLEFT;
elseif(vPoint.Y>=ClientSize.Height-5)
m.Result=(IntPtr)HTBOTTOMLEFT;
elsem.Result=(IntPtr)HTLEFT;
elseif(vPoint.X>=ClientSize.Width-5)
if(vPoint.Y<=5)
m.Result=(IntPtr)HTTOPRIGHT;
elseif(vPoint.Y>=ClientSize.Height-5)
m.Result=(IntPtr)HTBOTTOMRIGHT;
elsem.Result=(IntPtr)HTRIGHT;
elseif(vPoint.Y<=5)
m.Result=(IntPtr)HTTOP;
elseif(vPoint.Y>=ClientSize.Height-5)
m.Result=(IntPtr)HTBOTTOM;
break;
case0x0201://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=newIntPtr(2);//鼠标放在标题栏内
base.WndProc(refm);
break;
default:
base.WndProc(refm);
break;
}
}
希望本文所述对大家的C#程序设计有所帮助。
