WTL child window tabbing order

[nemo]

I have been tasked to update a WTL program. The program creates many modeless windows, the windows are created with style pop-up and the parent for the window is set to NULL in the create call. The main problem is the tabbing order on the modeless windows is not working. I have verified the VK_TAB message arrives in the main dialog(pretranslate message function) that created the modeless dialogs. How do I go about forwarding the message to the appropriate dialog, or is there a simpler solution to make the tabbing work? I have never had to work with the tabbing msgs before and it all seems a bit mysterious what is really going on. TIA

Try something like this:

virtual BOOL PreTranslateMessage(MSG* pMsg)
{
// If it's a 'Tab' key then the child dialog should handle it
if (pMsg->message == WM_KEYDOWN && pMsg->wParam == VK_TAB)
return m_dlgChild.PreTranslateMessage(pMsg);
}

Then in your child dialog message handler you handle it. Igor.

Each modeless window (I assume they're all dialogs?) should derive from CMessageFilter and override the PreTranslateMessage() method. The PreTranslateMessage() would do:

BOOL CYourWindow::PreTranslateMessage ( MSG* pMsg )
{
return IsDialogMessage ( pMsg );
}

In each window's OnInitDialog(), register for pre-translate calls with:

CMessageLoop* pLoop = _Module.GetMessageLoop();

ATLASSERT(pLoop != NULL);
pLoop->AddMessageFilter ( this );

Look at the wizard-generated CMainFrame::OnCreate() if this part is still unclear. -- I'm Michael Dunn and I approve this post. Vote Trogdor in oh-four!
