With an eye on gtk_tree_set_row_drag_data() which looks like it refuses to act on a selection data of any other target value. Makes you wonder if it ought to allow NULL or NONE or whatever at least ... (a matter for gtk of course). > I found one instance in gtk/gtkdnd.c, gtk_drag_drop().

I was expecting to see someone storing GTK_TREE_MODEL_ROW into target, which is what you get in the callback, and makes gtk_tree_set_row_drag_data work. Perhaps that happens indirectly iterating through the "target list" built from row_targets[] array in gtktreeview.c. (I'm pretty fuzzy on the dnd. At the X level it's pretty awful but nearly understandable. By the time gtk half buries it under two levels of abstraction it's pretty hopeless :-) > Is there a way to automatically test this stuff?

I guess that'd be the way, a bit like hard work though. _______________________________________________ gtk-perl-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtk-perl-list
