Move sizer hierarchy inside another sizer

Hi,

I have some pages that are designed under wxFormBuilder and I would like to
add by code a panel below taking 13% of the space.
So I am trying to move the page 's sizer inside another sizer and to
declare the right proportion but it doesn't work.
Here is what I tried :

enum { NAVPANEL_PERCENT_SZE = 13 };

wxSizer* pPageSizer = pWndPage->GetSizer();
if (pPageSizer)
{
wxBoxSizer* pNewPageSizer = new wxBoxSizer( wxVERTICAL );
pWndPage->SetSizer(pNewPageSizer);
pNewPageSizer->Insert(0, pPageSizer, 100 - NAVPANEL_PERCENT_SZE,
wxALL|wxEXPAND);
wxBoxSizer* pNavPanelSizer = new wxBoxSizer( wxVERTICAL );
StatusAndNavigateHTMLPanel* pNavStatus = new
StatusAndNavigateHTMLPanel(pWndPage, true);
pNavPanelSizer->Add(pNavStatus, NAVPANEL_PERCENT_SZE, wxALL|wxEXPAND);
pNewPageSizer->Add(pNavPanelSizer, NAVPANEL_PERCENT_SZE, wxALL|wxEXPAND);
pWndPage->Layout();
}

I assume that when I do pWndPage->SetSizer(pNewPageSizer); the sizer is
deallocated and that's why maybe it doesn't work.
So my question is how can I change the sizer tree to achieve what I want.

Thanks

If this is correct, then you just need to pass "false" as second argument
of SetSizer() to prevent the old sizer from being deleted.
