XTP 13.4.1, Windows 7. I had to struggle a bit to catch this one!

I have a CDateTimeCtrl inside a CXTPControlCustom control.

1) Minimize the ribbon.

2) Click on the datepicker dropdown button. The well-known date-picker popup is shown.

3) Now select a date. WM_LBUTTONDOWN will be captured - and trigger a call to SetPopuped(-1).

Clearly this is wrong! I didn't click what I expect "outside ribbon". What happened here, is that your mouse-hook interpreted this WM_LBUTTONDOWN as a "click in void". We need an extra check somewhere in CXTPMouseManager::PreTranslateMouseEvents.

Here's the error:

if ((nHtCode != HTERROR) && ((nHtCode == HTCLIENT) || ::IsChild(pCommandBar->GetSafeHwnd(), hWndMouse)))

{

hWndMouse equals HTNOWHERE. And the IsChild-call fails due to this:

GetParent(hWndMouse) == "DropDown" <-- bummer!

GetParent("DropDown") == "XTPPopupBar"

Thus, what you need is to iterate upwards, and see if you ever hit that XTPPopupBar window!

Something like this:

BOOL CXTPCommandBar::IsWindowRelated(HWND hWnd)

{

HWND hWndParent = ::GetParent(hWnd);

while (hWndParent)

{

if (hWndParent == m_hWnd)

return TRUE;

hWndParent = ::GetParent(hWndParent);

}

return FALSE;

}

if ((nHtCode != HTERROR) && ((nHtCode == HTCLIENT) || pCommandBar->IsWindowRelated(hWndMouse))))

{

Please provide a fix a la codejock style so that I can update my source code a.s.a.p!

Thanks!

Hi,

Thanks finally fixed. Actually you made very good reserch and we did it with your way:

BOOL CXTPMouseManager::IsRelated(HWND hWndParent, HWND hWnd) const

{

while (hWnd)

{

if (hWnd == hWndParent)

return TRUE;

hWnd = ::GetParent(hWnd);

}

return FALSE;

}

...

if ((nHtCode != HTERROR) && ((nHtCode == HTCLIENT) || ::IsChild(pCommandBar->GetSafeHwnd(), hWndMouse) || IsRelated(pCommandBar->GetSafeHwnd(), hWndMouse)))
