gtk:tree-drag-dest-row-drop-possible (dest path value)

dest -- a gtk:tree-drag-dest object
path -- a gtk:tree-path instance with the destination row
value -- a g:value instance with the data being dropped

True if a drop is possible before dest.

Determines whether a drop is possible before the given dest, at the same depth as dest. That is, can we drop the data in data at that location. The dest argument does not have to exist. The return value will almost certainly be false if the parent of dest does not exist, though. The gtk:tree-drag-dest implementation is deprecated since 4.10. Use list models instead.
