Nasty side effect of changes in CXTPSplitterWnd

Hello everyone!

Since I’ve upgraded my project from XTP 15.0.2 to 15.1.3 I have problem with nested splitters. In this case resizing of splitters did not work properly.

For reproducing this problem you can take SplitterWindow example from the XTP installation package and replace CMainFrame::OnCreateClient method with the following code.

BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT /*lpcs*/, CCreateContext* pContext)

{

      if (!m_wndSplitter.CreateStatic(this, 1, 2))

      {

            TRACE0("Failed to create splitter window\n");

            return FALSE;

      }

      if (!m_wndSplitter1.CreateStatic(&m_wndSplitter,     

            2, 1,                                          

            WS_CHILD | WS_VISIBLE | WS_BORDER,                   

            m_wndSplitter.IdFromRowCol(0, 0))) 

      {

            TRACE0("Failed to create nested splitter\n");

            return FALSE;

      }

      m_wndSplitter1.CreateView(0,0, RUNTIME_CLASS(CView2), CSize(20, 20), pContext);

      m_wndSplitter1.CreateView(1, 0,  RUNTIME_CLASS(CView3), CSize(0, 0), pContext);

      m_wndSplitter.CreateView(0, 1,  RUNTIME_CLASS(CView1), CSize(0, 0), pContext);

      CRect r;

      GetClientRect(&r);

      m_wndSplitter.SetRowInfo( 0, r.Height()/2, 0 );

      m_wndSplitter.SetColumnInfo( 0, r.Width()/2, 0 );

      return TRUE;

}

…

The member m_wndSplitter1 has to be defined the MainFrm.h header.

…

CXTPSplitterWnd  m_wndSplitter1;

In this example you can see that the vertical splitter can’t be resized.

It would be great if you have any fix or workaround for the problem. 

Best regards,
