After studying the wxNotebook sources (mainly src\generic\toolbkg.cpp,
src\common\bookctrl.cpp), I came to the conclusion that there is no built
in code that will take into account the wxToolBar member's dimension.

In my case, the following lines did the trick:

    m_pToolbook->ChangeSelection(0);
    m_pToolbook->Fit();
    wxSize
      sBar=m_pToolbook->GetToolBar()->GetToolSize(),
      sBook=m_pToolbook->GetSize();
    m_pToolbook->SetMinSize(wxSize(
      std::max<int>(sBook.GetWidth(), sBar.GetWidth()),
      std::max<int>(sBook.GetHeight(), sBar.GetHeight()*m_pToolbook->GetPageCount())
      ));
    pMainSizer->Add(m_pToolbook);

    pMainSizer->SetSizeHints(this);
    Layout();

Of course, this is not very generic (only works for wxNB_LEFT) and also
kinda clumsy, but maybe people who know the wxToolbook/wxNotebook interna
better than me can implement something likewise in one of the next releases.

HTH,
Volker
