They does just not know it yet. ;)

Ok. I was writing a clipboard for gnome with a lot of enchantments, but has
now abrandoned the project because I have found out that X itself allready
has got a clipboard that is powerful enough.

The X-clipboard works basically the same way as X-DnD. You declare what you
want to put in the clipboard ( you may declare more than one type of data ).
Whenever another application want's to paste, your app will be notifyed
about this. From what I remember, you allso have the possibility to store
data drectly in the clipboard ( that will remain if your app shuts down ).

The main problem with the X-clipboard is that it is called "selection", so
nobody appears to understand what it is.

Oh, and, the second problem is that there is allmost none documentation
about this...

Gtk+ has got a wrapper around this (GtkSelection) , as it allso have for the
DnD.
gtkDnD is compatible with older applications, and I believe that
gtkselection is compatible as well, allthough I have not tested this ( I
became a bit "tired" when I realized that I had worked for over half a year
with something completely needless :(

So I guess that the only help needed is DOCUMENTATION, where you clearly can
read about the selection mechanism togeather with drag-and-drop, and where
it's absolutely clear that selcetion is the X'equiallence of M$ clipboard...
