CXTPSplitterWnd bug

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   When creating splitter windows that are inside other splitter windows, then it's not possible to resize them any more. If you test this code, and then try to move the horizontal splitter window, it moves like a few pixels and then it stops tracking.

To easily reproduce the bug, then in your Splitter window sample replace the CMainFrame::OnCreateClient code with this to create a T shaped splitter.

// Create the first splitter
   m_wndSplitter.CreateStatic(this, 2, 1);
   m_wndSplitter.CreateView(1, 0, RUNTIME_CLASS(CView3), CSize(0, 0), pContext);

   // Create the second splitter
   m_wndSplitter2.CreateStatic(&m_wndSplitter, 1, 2, WS_CHILD | WS_VISIBLE | WS_BORDER, m_wndSplitter.IdFromRowCol(0, 0));
   m_wndSplitter2.CreateView(0, 0, RUNTIME_CLASS(CView1), CSize(0, 0), pContext);
   m_wndSplitter2.CreateView(0, 1, RUNTIME_CLASS(CView2), CSize(0, 0), pContext);

It works with CSplitterWnd..

	Hi, as a workaround please replace CXTPSplitterWnd with the following class: class CMySplitterWnd : public CXTPSplitterWnd { void StopTracking(BOOL bAccept) { m_rectTracker.left -= 2; CXTPSplitterWnd::StopTracking(bAccept); } }; I reported this bug 4 years ago!
