Question

MFC中如何判断鼠标是否在picture控件范围内？

请问应该在MOUSEMOVE里怎么样写这个函数？求代码。谢谢

Answer 1

void C********::OnMouseMove(UINT nFlags, CPoint point)
{
ClientToScreen(&point);
CRect rect;
GetDlgItem(图像控件ID)->GetClientRect(rect);
GetDlgItem(图像控件ID)->ClientToScreen(rect);
if(rect.PtInRect(point) ) //鼠标是否在控件范围之内
{

}
CDialog::OnMouseMove(nFlags, point);
}

Answer 2

bool ck=true;POINT pt;
void CMfccsDlg::OnMouseMove(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
RECT rect;
::GetWindowRect(GetDlgItem(IDC_STATIC1)->m_hWnd,&rect);
GetCursorPos(&pt);
if((pt.x<rect.left||pt.x>rect.right||pt.y<rect.top||pt.y>rect.bottom)&&ck)
{
MessageBox("移出");
ck=false;
}
else
ck=true;
CDialog::OnMouseMove(nFlags, point);
}
