Dear McNeel Support,
We are currently porting our Rhino 5 C++ Plugin to Rhino 6. However in Rhino 6 we are experiencing Problems loading our custom TabbedDockBar derived from CRhinoTabbedDockBarDialog.
Registering the DockBar through CRhinoTabbedDockBarDialog::Register(…) returns true. However the Tabbed Dock bar is not being created afterwards. Also, ::OnInitDialog() is never being called.
In the Rhino 5 SDK on the other hand, we see a call to the constructor as well as OnInitDialog() issued by some WindowsEvent right after CRhinoUtilityPlugIn::OnLoadPlugIn().
Are there some changes in the Rhino 6 SDK regarding loading a Tabbed Dock Bar we need to consider? At least in the comments in the header of CRhinoTabbedDockBarDialog we don’t see any substantial modifications.
Thank you for your help,
