控件给主窗口发送消息-直接调用onmousemove
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | class CTitleButton : public CBCGPButton { DECLARE_DYNAMIC(CTitleButton) public : CTitleButton(); virtual ~CTitleButton(); protected : DECLARE_MESSAGE_MAP() public : afx_msg void OnMouseMove( UINT nFlags, CPoint point); }; |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | IMPLEMENT_DYNAMIC(CTitleButton, CBCGPButton) CTitleButton::CTitleButton() : CBCGPButton() { } CTitleButton::~CTitleButton() { } BEGIN_MESSAGE_MAP(CTitleButton, CBCGPButton) ON_WM_MOUSEMOVE() END_MESSAGE_MAP() void CTitleButton::OnMouseMove( UINT nFlags, CPoint point) { CWnd* pParent = GetParent(); if (pParent) { pParent->SendMessage(WM_MOUSEMOVE, nFlags, MAKELPARAM(point.x, point.y)); } CBCGPButton::OnMouseMove(nFlags, point); } |
主窗口中的OnMouseMove如下调用:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | void CDlgMain::OnMouseMove( UINT nFlags, CPoint point) { static CPoint PrePoint = CPoint(0, 0); if (MK_LBUTTON == nFlags) { if (point != PrePoint) { ***** CPoint ptTemp = point - PrePoint; GetMainWnd()->GetWindowRect(&rcWindow); ****** rcWindow.OffsetRect(ptTemp.x + ioff, ptTemp.y); GetMainWnd()->MoveWindow(&rcWindow); } } } |
