OP has a dialog in a View. I thought that should get a chance by default.

Hi,
I have a form view with some controls and a tab window with other
dialogs as tab pages. I need to handle some key combination on the form
view to change the active tab page.
To do this, I added an entry in the accelerator table and the
corresponding command handler on my form view. This is working fine, but
only when the form view has the focus. If I set the focus to the tab
window or any tab page, the command doesn't get routed to the form view.
Is there any way of doing this (other than handling the command on each
tab page)?
Thanks,
Pedro Ferreira
This is how I did it for a dialog which can contain multiple tab controls:
bool
IsSuitableTabCtrl(CWnd* pWnd, SubDialogTabCtrl*& pTab)
{
pTab = dynamic_cast<SubDialogTabCtrl*>(pWnd);
if (pTab && pTab->GetItemCount() <= 1)
pTab = 0;
return pTab;
}
BOOL BaseDialog::PreTranslateMessage(MSG* pMsg)
{
if (::TranslateAccelerator(m_hWnd, m_hAccel, pMsg))
return true;
else if (pMsg->message == WM_KEYDOWN
&& pMsg->wParam == VK_TAB
&& GetKeyState(VK_CONTROL) < 0)
{
SubDialogTabCtrl* pTab = 0;
// Prefer tab control containing the focused item.
CWnd* pFocus = GetFocus();
if (IsChild(pFocus))
{
for ( ; pFocus != this; pFocus = pFocus->GetParent())
{
if (IsSuitableTabCtrl(pFocus, pTab))
break;
}
}
// If no tab control contains the focus window, check immediate
// children for a suitable tab control.
if (!pTab)
{
for (CWnd_iterator i(GetWindow(GW_CHILD)), iLim = CWnd_iterator();
i != iLim;
++i)
{
if (IsSuitableTabCtrl(&*i, pTab))
break;
}
}
if (pTab)
{
if (GetKeyState(VK_SHIFT) < 0)
pTab->PrevPage();
else
pTab->NextPage();
return true;
}
}
return base::PreTranslateMessage(pMsg);
}
You would do something very similar inside your form view class.
