This is another tab window class that provides support to dynamic splitter window. If you are not going to support dynmaic splitter window, it is recommended to use the CGXTabWnd in the library. The CGXDTabWnd class displays a tab-beam control on the bottom-left side of the frame window. When it is used together with CGXDSplitWnd, only one tab-beam control is drawn on the bottom-left side of the frame window even when user splitter the window by dragging the splitter box using mouse. This behavior is similar to that of workbooks in the MS Excel 2000.
