tree_get_row_drag_data

function tree_get_row_drag_data(selection_data:Gtk.SelectionData):Boolean {
    // Gjs wrapper for gtk_tree_get_row_drag_data()
}

Obtains a tree_model and path from selection data of target type %GTK_TREE_MODEL_ROW. Normally called from a drag_data_received handler. This function can only be used if selection_data originates from the same process that's calling this function, because a pointer to the tree model is being passed around. If you aren't in the same process, then you'll get memory corruption. In the Gtk.TreeDragDest drag_data_received handler, you can assume that selection data of type %GTK_TREE_MODEL_ROW is in from the current process. The returned path must be freed with Gtk.TreePath.prototype.free.
