VC++无标题窗口以及控件拖动的方法(修正)

无标题窗口拖动：

方法一：直接在OnNcHitTest中虚拟发送HTCAPTION消息

[cpp] view plaincopyprint?

1. UINT CMainFrame::OnNcHitTest(CPoint point)   
2. {  
3.  RECT rectWindows, rectClient;  
4.  this->GetWindowRect(&rectWindows);  
5.  this->GetClientRect(&rectClient);  
6.    
7.  if (point.y > rectWindows.top && point.y < rectWindows.top + 25)  
8.  {  
9.   return HTCAPTION;//标题栏形式  
10.  }  
11.  else  
12.  {  
13.   return CFrameWnd::OnNcHitTest(point);  
14.  }  
15. }   

UINT CMainFrame::OnNcHitTest(CPoint point) { RECT rectWindows, rectClient; this->GetWindowRect(&rectWindows); this->GetClientRect(&rectClient);  if (point.y > rectWindows.top && point.y < rectWindows.top + 25) {  return HTCAPTION;//标题栏形式 } else {  return CFrameWnd::OnNcHitTest(point); }} 

方法二：直接在OnLButtonDown中虚拟发送WM_NCLBUTTONDOWN，HTCAPTION消息

 

[cpp] view plaincopyprint?

1. void CMyDlg::OnLButtonDown(UINT nFlags, CPoint point)   
2. {  
3.     if (point.y < 26)  
4.         PostMessage(WM_NCLBUTTONDOWN,HTCAPTION,MAKELPARAM(point.x,point.y));  
5.       
6.     CDialog::OnLButtonDown(nFlags, point);  
7. }   

void CMyDlg::OnLButtonDown(UINT nFlags, CPoint point) {if (point.y < 26)PostMessage(WM_NCLBUTTONDOWN,HTCAPTION,MAKELPARAM(point.x,point.y));CDialog::OnLButtonDown(nFlags, point);} 

方法三：通过在OnMouseMove中手动进行处理

[cpp] view plaincopyprint?

1. void CMyDlg::OnMouseMove(UINT nFlags, CPoint point)  
2. {  
3.  // TODO: Add your message handler code here and/or call default  
4.        static CPoint PrePoint = CPoint(0, 0);  
5.        if(MK_LBUTTON == nFlags)  
6.        {  
7.              if(point != PrePoint)  
8.              {  
9.                     CPoint ptTemp = point - PrePoint;  
10.                     CRect rcWindow;  
11.                     GetWindowRect(&rcWindow);  
12.                     rcWindow.OffsetRect(ptTemp.x, ptTemp.y);  
13.                     MoveWindow(&rcWindow);  
14.                     return ;  
15.               }  
16.   
17.        }  
18.   
19.        PrePoint = point;  
20.        CDialog::OnMouseMove(nFlags, point);  
21. }  

void CMyDlg::OnMouseMove(UINT nFlags, CPoint point){ // TODO: Add your message handler code here and/or call default       static CPoint PrePoint = CPoint(0, 0);       if(MK_LBUTTON == nFlags)       {             if(point != PrePoint)             {                    CPoint ptTemp = point - PrePoint;                    CRect rcWindow;                    GetWindowRect(&rcWindow);                    rcWindow.OffsetRect(ptTemp.x, ptTemp.y);                    MoveWindow(&rcWindow);                    return ;              }       }       PrePoint = point;       CDialog::OnMouseMove(nFlags, point);}

 

控件拖动：

控件拖动只能采用上述的第三种方法
