gtk 1.1.[12,13]: motiv and xdnd DND callback order

[Rasca Gmelch <thron gmx de>]

hi,

i've some problems to understand the order in which the DND
callbacks are called.

inside a gtk ctree widget i get the following debug output
from my program:

on_drag_begin()
on_drag_motion()
on_drag_data_get()
on_drag_data()
on_drag_data_delete()
on_drag_data_leave()

sounds quite good, isn't it?
in on_drag_data_leave() i reset a value which i need to make
same visual effects during drag_motion(). but that doesn't work
during a motiv DND (motiv -> ctree) operation, cause there the
order is in this way:

on_drag_motion()
on_drag_leave()
on_drag_data()

the "drag_data_received" callback is called *after* the leave-callback :(
is that a bug or a feature or do i have to do special things in
my code to ensure that the drag_leave comes at the right time??

btw. i've wrote to the gtk-app list some time before that i was
not able to initialize a DND op. from one toplevel with ctree
widget to an other toplevel also with a ctree widget. this problem
is gone away since 1.1.13, great work.
