MFC Library User Interfaces
In addition to providing options for SDI, MDI, and MTI-style application interfaces, the MFC library gives you a choice between a standard application user interface (UI) and a Windows Explorer–style UI. Examples of the classic-style UI include Microsoft Word and Microsoft Paintbrush. The Windows Explorer– style UI features two panes separated by a splitter. The left pane usually includes a TreeView with expandable nodes, and the right pane usually includes a ListView. Windows Explorer is an example of this style of UI.
