Sizer help (min sizes, proportionality, and window resizing)

[Harvey Chapman]

Hello,

I'm trying to create a header of sorts at the top of a window using a  
horizontal box sizer. I want something like this:

Left Label <expandable space> Center Label <expandable space> Right  
Label

I can create that, but when a user resizes the window small enough the  
labels all start to overlap each other than just disappear off-screen  
as I would desire (and would happen if I used fixed sizes for the  
spaces with no proportionality).

So:

How can I have both proportionality and minimum sizes? Do I have to  
always set the minimum sizes myself?

Below, I've included code (generated by wxDesigner) that illustrates  
the problem (parent is an empty wxFrame). Worth noting is the fact  
that the text control does n fact limit the minimum size of the  
window(frame).

Thank you,

Harvey


     wxBoxSizer *item0 = new wxBoxSizer( wxVERTICAL );

     wxBoxSizer *item1 = new wxBoxSizer( wxHORIZONTAL );

     wxStaticText *item2 = new wxStaticText( parent, ID_TEXT, _("Some  
Longer Text Indeed"), wxDefaultPosition, wxSize(160,10), 0 );
     item1->Add( item2, 0, wxGROW|wxALIGN_CENTER_HORIZONTAL|wxALL, 5 );

     item1->Add( 25, 20, 1, wxALIGN_CENTER|wxALL, 5 );

     wxStaticText *item3 = new wxStaticText( parent, ID_TEXT, _("Some  
Longer Text Indeed"), wxDefaultPosition, wxDefaultSize, 0 );
     item1->Add( item3, 0, wxALIGN_CENTER|wxALL, 5 );

     item1->Add( 20, 20, 1, wxALIGN_CENTER|wxALL, 5 );

     wxStaticText *item4 = new wxStaticText( parent, ID_TEXT, _("Some  
Longer Text Indeed"), wxDefaultPosition, wxDefaultSize, 0 );
     item1->Add( item4, 0, wxALIGN_CENTER|wxALL, 5 );

     item0->Add( item1, 0, wxGROW|wxALIGN_CENTER_VERTICAL|wxALL, 5 );

     wxTextCtrl *item5 = new wxTextCtrl( parent, ID_TEXTCTRL, wxT(""),  
wxDefaultPosition, wxSize(400,200), wxTE_MULTILINE );
     item0->Add( item5, 1, wxGROW|wxALIGN_CENTER_VERTICAL|wxALL, 5 );

     if (set_sizer)
     {
         parent->SetSizer( item0 );
         if (call_fit)
             item0->SetSizeHints( parent );
     }
