Advanced Windows Application UI (MDI Tabbed Group)

Question

I would like to be able to create an MDI UI layout that extends the behavior of MDI Tabbed Groups in the following way. Within a pane for a split tabbed group, I'd like to create a nested tab group with the opposite directional alignment. For instance, given a horizontally split top level, I would like to create a vertically split tab group within the first pane. This appears to necessitate a rework of the CMDIFrameWndEx and associated classes.

The Tabbed Group Layout is an appealing UI device. It's a shame it's not available in mainstream web browsers. Am I right in assuming that its best support is in the Visual C++ Feature Pack?

Answer 1

Here's one example, at least. Also, AvalonDock. I guess MFC remains a laggard in many respects.
