Summary: wxBoxSizer don't  update size in Layout()

Initial Comment:
[wxMSW 2.8.0, WinXP, VS8.0]

Hi!
I have vertical box sizer, aligned right. It contains wxStaticText and wxStaticLine(horizontal). All with proportion == 0. Static text is aligned to right. Static line was added with wxEXPAND flag.
First static text contains text "+++++++++++" and static line is expanded beyound this text and have width same as text.
However when I change text to "-" and after call Layout() static line remains with old size.

The resone of this is that RecalcSizes() don't take into account size, that was calculated in CalcMin(), but uses m_size for items with wxEXPAND, wxSHAPED flags.

It is better to use in RecalcSizes():
//================================================================
                wxPoint child_pos( pt );
                wxSize  child_size( size.x, height );

                if (item->GetFlag() & (wxEXPAND | wxSHAPED))
                    child_size.x = m_size.x;
//================================================================

This:
//================================================================
                wxPoint child_pos( pt );
                wxSize  child_size( size.x, height );

                if (item->GetFlag() & (wxEXPAND | wxSHAPED))
                    child_size.x = m_minWidth;
//================================================================

But I am not sure of this.
