[wxperl-users] Wx::DropTarget -> OnDragOver

[Marco T. <wx...@so...>]

hello

for wxDragResult the docs tell me that OnDragOver:
Returns the desired operation or wxDragNone.
-> Determined by SHIFT or CONTROL key states.

because of this, i expect this return values:
-> "wxDragCopy" if i press "Control"
-> "wxDragMove" if i press no key or "Shift"
-> "wxDragNone" never

im really confused...
can someone bring light into my darkness and explain me in which
situation which value should be returned?
or why wxPerl/wxWindows always returns "wxDragNone"? i mean
"wxDragResult" should follow the key states...

respectively, i just wish to differentiate between "wxDragCopy" and
"wxDragMove" and wish to know if "Control" is pressed.
How can i get this information?

greeting
Marco
