TTabSheet is not copyable because it is not a standalone component to begin
with. It is part of another component, and as such the IDE will not copy it
directly.

As has already been mentioned before, you cannot override
TDefaultEditor::Copy() to do what you are asking for. The component has
already been copied to the clipboard *BEFORE* TDefaultEditor::Copy() is
called. Your best bet would be to just clear the clipbaord manually at that
point, rather than trying to prevent the copy in the first place.

I am developing a component SAME AS TPageControl named by
TPaneControl and only it can container of TPane that is
developed by me too, also TPan can be only Child of
TPaneControl.
Now I need to disable CUT & COPY facility of TPane
(Exactly same as TTabSheet).
If you just clear Clipboard manually in Copy Method of
TDefaultEditor you may lost your Component when you cutting it,
isn't it?

How EXACTLY are your classes set up?

I know of no way to disable those, and I cannot find any documentation of it
anywhere, official or otherwise. Whatever Borland is doing with TTabSheet,
it is a private implementation that only they know about. It is not
something that is controlled via runtime code, so it must be something
implemented in one of the private design-time packages which Borland does
not distribute the source code for.
