Win32 Toolbar and TBSTYLE_WRAPABLE - c++

Question

I have a toolbar which doesn't wrap on WM_SIZE message to its parent. Here is create code for toolbar:
// create toolbar
g_hTool = CreateWindowEx( 0, TOOLBARCLASSNAME, NULL,
WS_CHILD | WS_VISIBLE | TBSTYLE_WRAPABLE, 0, 0, 0, 0,
hWnd, ( HMENU )IDC_TEX_TOOL, GetModuleHandle( NULL ), NULL );
// Send the TB_BUTTONSTRUCTSIZE message, which is required for backward compatibility.
SendMessage( g_hTool, TB_BUTTONSTRUCTSIZE, ( WPARAM )sizeof( TBBUTTON ), 0 );
SendMessage( g_hTool, TB_SETBUTTONSIZE, 0, MAKELPARAM( 32, 32 ) );
SendMessage( g_hTool, TB_SETBITMAPSIZE, 0, MAKELPARAM( 32, 32 ) );
SendMessage( g_hTool, TB_SETEXTENDEDSTYLE, 0, ( LPARAM )TBSTYLE_EX_DRAWDDARROWS );
here is WM_SIZE( handled by parent window ):
switch( uMsg ):
{
...
case WM_SIZE:
{
// get auxiliary viewport toolbar window handle and autosize
SendMessage( g_hTool, TB_AUTOSIZE, 0, 0 );
RECT cr;
GetWindowRect( g_hTool, &cr );
nTexToolHeight = cr.bottom - cr.top;
// get status bar window handle and autosize
SendMessage( g_hStatus, WM_SIZE, 0, 0 );
// get status bar height
GetWindowRect( g_hStatus, &cr );
nTexStatusHeight = cr.bottom - cr.top;
break;
}
...
}
any idea why the toolbar won't wrap? The buttons extend beyond the extents of the parent window. The buttons that extend beyond the window are clipped but the toolbar isn't resized and the buttons remain unseen...
