KDDockWidgets not only works fine on Windows it also implements some native features:

  • Aero-snap support (drag to screen edges to partially-maximize windows)
  • Support for native Windows drop shadow around the frame
  • Support mixing with MFC event loop

Note: MinGW compiler is not tested, but probably works.
Note: KDDW is tested with Windows 10 and 11. Windows 7 can be made to work, upon request.
