Objective Toolkit provides docking windows. Objective Toolkit’s docking views greatly extend this capability by allowing you to dock complete MFC CViews and frame windows. Docking views is an enhancement to MDI that allows you to convert any document window (for example, MDI child) into a docking window. Docking views builds on the capabilities of the Extended Control Bar Architecture, which allows you to dock not only control bars but also CViews, CSplitterWnds or any arbitrary CWnd-derivative.
