Adding Office 2007 tooltips to regular CButtons

Hi,

I want to add Office 2007 style tooltips to regular CButtons inside a CDialog. Could anyone please outline the necessary steps? I.e. I don't know what to do with the CXTPToolTipContext.

Thanks!

Hi,

In OnInitDialog() I call now m_moduleContext.SetModuleToolTipContext();
This works as long as nobody else calls EnableTooltips() because the following lines in mfc/tooltips.cpp overwrites the m_pfnFilterToolTipMessage function pointer.

BOOL CWnd::_EnableToolTips(BOOL bEnable, UINT nFlag)
{
    [...]

    // if already enabled for tooltips, nothing to do
    if (!(m_nFlags & nFlag))
    {
        // success
        AFX_MODULE_STATE* pModuleState = _AFX_CMDTARGET_GETSTATE();
        pModuleState->m_pfnFilterToolTipMessage = &CWnd::_FilterToolTipMessage;
    }
    [...]
}

Another approach I tried, is to call m_moduleContext.FilterToolTipMessage(this, pMsg); in PreTranslateMessage(). But this has the downside that I need to change every window with tooltips.

Do you have any other hints for me?

So if every call of EnableToolTips resets the desired effect, when and where should I call it?

Thanks,
Gregor
