Re: TkDND: Tk and drag n' drop - Help in improving it...

Unfortunatelly, this cannot be done. The XDND protocol (unix) specifies
that the drop target may request to see the data, in order to decide
if it is going to accept the drop.

But that's fine (i.e. I don't view it as incompatible with what I
wrote). If the drop target requests it, the drag site has promised it
can therefore provide it. The issue is to avoid being forced to provide
vast amounts of data just to initiate a drag. Most sensible, normal
drop targets should not request all of the data, but just request some
information about it ("what extension does that file have?", "how large
is that file?", perhaps "what's in the first few lines of the file?",
etc). But, if a drop target really wants all of the data, it should be
allowed to ask for it on any platform.
