It has to be noted that the API for drag and drop in wxWindows is not
yet finished which is mostly due to the fact that DnD support under
GTK 1.0 is very rudimentary and entirely different from the XDnD
protocol used by GTK 1.2. This also entails that not all of the documentation
concerning DnD might be correct and some of the code might get broken
in the future. The next release of wxWindows will be based on GTK 1.2
and will hopefully include a much improved DnD support. The general
design on the wxDropSource side will be the same but especially the
wxDropTarget is almost certain to change.
Note that wxUSE\_DRAG\_AND\_DROP must be defined in setup.h in order
to use Drag'n'Drop in wxWindows.
