Custom slider control with text - how?

I ended up with deriving my "Control" from wxPanel:

<wxAdvancedSlider.cpp>
 class wxAdvancedSlider : public wxPanel
 {
   DECLARE_DYNAMIC_CLASS(wxAdvancedSlider);
   DECLARE_EVENT_TABLE();
 public: 
   wxAdvancedSlider() : m_pSlider(NULL), m_pText(NULL) { }
   wxAdvancedSlider(wxWindow* parent, wxWindowID id, int value , int minValue, int maxValue, const wxPoint& pos=wxDefaultPosition, const wxSize& size=wxDefaultSize, long style=wxSL_HORIZONTAL, const wxValidator& validator=wxDefaultValidator, const wxString& name=wxT("AdvancedSlider"))
   {
     Create(parent, id, value, minValue, maxValue, pos, size, style, validator, name);
   }
   bool Create(wxWindow* parent, wxWindowID id, int value , int minValue, int maxValue, const wxPoint& pos=wxDefaultPosition, const wxSize& size=wxDefaultSize, long style=wxSL_HORIZONTAL, const wxValidator& validator=wxDefaultValidator, const wxString& name=wxT("AdvancedSlider"))
   {
     if(!wxPanel::Create(parent, id, pos)) return false;
     wxBoxSizer* pMainSizer=new wxBoxSizer(wxVERTICAL);
     m_pSlider=new wxSlider(this, wxID_ANY, value, minValue, maxValue, pos, size, style, validator, name);
     m_pText=new wxStaticText(this, wxID_ANY, name);
     pMainSizer->Add(m_pSlider, 0, wxEXPAND|wxALIGN_CENTER_HORIZONTAL|wxALIGN_TOP, 0);
     pMainSizer->Add(m_pText, 0, wxALIGN_BOTTOM|wxALIGN_CENTER_HORIZONTAL, 0);
     SetSizer(pMainSizer);
     SetInitialSize(size);
     return true;
   }
 
 private:
   wxSlider* m_pSlider;
   wxStaticText* m_pText;
 };
 
 IMPLEMENT_DYNAMIC_CLASS(wxAdvancedSlider, wxPanel);
 BEGIN_EVENT_TABLE(wxAdvancedSlider, wxPanel)
 END_EVENT_TABLE()
</wxAdvancedSlider.cpp>

However, there might be unwanted side effects of that inheritage.

Cheers,
Volker
