BCGControlBar Pro (MFC)
BCGControlBar for .NET
The library has a built-in "Carbon" application look. All basic GUI elements such as menus, toolbars and docking panes are drawn with a dark "carbon-style" theme, so the user can concentrate his look on the application view. You can change the look on the fly.
// Enable "Carbon" look:
CBCGPVisualManager::SetDefaultManager (RUNTIME_CLASS (CBCGPVisualManagerCarbon));
