How to move a dialog which does not have a caption
Introduction
This article is aimed at beginners, and presents two ways to move a dialog which does not have a caption by dragging its client area.
1. WM_SYSCOMMAND message
Sending the WM_SYSCOMMAND message starts the move operation. Add the following code to handle the mouse down event:
BEGIN_MSG_MAP(CMainDlg)
//...
MESSAGE_HANDLER(WM_LBUTTONDOWN, OnLButtonDown)
END_MSG_MAP()
LRESULT OnLButtonDown(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
{
SendMessage(WM_SYSCOMMAND, SC_MOVE|HTCAPTION);
return 0;
}
//...
MESSAGE_HANDLER(WM_LBUTTONDOWN, OnLButtonDown)
END_MSG_MAP()
LRESULT OnLButtonDown(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
{
SendMessage(WM_SYSCOMMAND, SC_MOVE|HTCAPTION);
return 0;
}
2. WM_NCHITTEST message
The idea is to handle the WM_NCHITTEST message to return HTCAPTION instead of HTCLIENT when the mouse is in the client area, to trick Windows to start moving the dialog.
BEGIN_MSG_MAP(CMainDlg)
//...
MESSAGE_HANDLER(WM_NCHITTEST, OnNcHitTest)
END_MSG_MAP()
LRESULT OnNcHitTest(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
{
if (::DefWindowProc(m_hWnd, uMsg, wParam, lParam) ==
HTCLIENT && ::GetAsyncKeyState(MK_LBUTTON) < 0)
return HTCAPTION;
return 0;
}
//For MFC
//Devil for ever supplied the MFC solution that is shown below (thanks!). The idea is the same - to handle the WM_NCHITTEST message.
UINT OnNcHitTest(CPoint point)
{
UINT nHit = CDialog::OnNcHitTest(point);
return (nHit == HTCLIENT ? HTCAPTION : nHit);
}
//...
MESSAGE_HANDLER(WM_NCHITTEST, OnNcHitTest)
END_MSG_MAP()
LRESULT OnNcHitTest(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
{
if (::DefWindowProc(m_hWnd, uMsg, wParam, lParam) ==
HTCLIENT && ::GetAsyncKeyState(MK_LBUTTON) < 0)
return HTCAPTION;
return 0;
}
//For MFC
//Devil for ever supplied the MFC solution that is shown below (thanks!). The idea is the same - to handle the WM_NCHITTEST message.
UINT OnNcHitTest(CPoint point)
{
UINT nHit = CDialog::OnNcHitTest(point);
return (nHit == HTCLIENT ? HTCAPTION : nHit);
}
