    MFC Tree Control: How to add checkboxes to a tree control?

    Q: How to add checkboxes to a tree control?


    • At design time, use the resource editor to enable the "Check boxes" style.

    • At run-time, add the 'TVS_CHECKBOXES' style to the tree control, after you have created it and before you have populated it.

      DWORD dwLong = m_tree.GetWindowLong(GWL_EXSTYLE);
      dwLong |= TVS_CHECKBOXES;
      m_tree.SetWindowLong(GWL_EXSTYLE, dwLong);
