Question

I have an interface that has two toolbars, one attached to the frame and one embedded in a notebook tab. The one in the frame dutifully shows longHelp strings in the statusbar, the one in the notebook tab
does not. How do I tell the one on the notebook tab where to display its help, or do I have to manage enter and leave bindings myself?

You have in wxWidgets:

void wxToolBarBase::OnMouseEnter(int id)
{
    ...
    wxFrame *frame = wxDynamicCast(GetParent(), wxFrame);
    if ( frame )
    {
        ...
        frame->DoGiveHelp(help, id != wxID_ANY);
    }
    ...
}

In C++ program you can override this function (simply changing GetParent() to GetTopLevelParent() should work). In Python you can only, as you wrote, bind enter/leave events and call DoGiveHelp() from handlers.
