如何用OnMouseMove()获取MFC对话框的相对坐标

请写详细些 谢谢

Answer 1

C/C++ code//ButtonEx.cpp --CButtonEx基类是CButton类
LRESULT CButtonEx::OnMouseHover(WPARAM wParam, LPARAM lParam)
{
CRect rectBtn;
CPoint point;

GetWindowRect( rectBtn );
GetCursorPos( &point );
if ( rectBtn.PtInRect( point ) )
{
m_bInBn = true;
MessageBox( "移动到按钮上了！222222" ); //这个很准，移动上就有反应
}

return 1;
}

//test.cpp
for ( int iNum = 0; iNum < (int)m_vecButton.size(); iNum++ )
{
CButtonEx *pBn = m_vecButton[iNum];
if ( NULL != pBn )
{
if ( pBn->m_bInBn )
{
MessageBox( "移动到按钮上了！" ); //这个就不准了。。为什么啊？
break;
}
}
}

Answer 2

OnMouseMove(UINT nFlags, CPoint point) point.x和point.y分别是鼠标相对于对话框的相对坐标
