Description Leo Ufimtsev CLA 2015-01-26 09:43:19 EST 
This is sort of bug/missing functionality:

In:
Bug 457224 - FileTransfer does not work on Ubuntu 14.04

It was pointed out that SWT's GTK implementation doesn't have a mechanism to get data during a drag-enter event.  (as does the win implementation). 
An example of this is the attached sample (in 457224) where data isn't acquired on a drag-enter.

As a result, on gtk you can't filter out 'bad' data on a drag-enter event. 

GTK folks in:
https://bugzilla.gnome.org/show_bug.cgi?id=686197

Suggested to use gtk_drag_get_data() 
to get data for 'drag-over' events, as described in:
https://developer.gnome.org/gtk3/stable/GtkWidget.html#GtkWidget-drag-motion

I won't have time to work on this in near future, but might come back to it if I do some DND work. 
Anyone interested is invited to work on it.
