Hi,
There is a get_dest_row_at_pos() method in TreeView which sometimes
returns null for a TreePath. The only way I could find for testing
whether the path is null is through gobj(). Code snippet:
...
Gtk::TreePath path;
treeView->get_dest_row_at_pos (x, y, path, pos);
if (path.gobj () != 0) {
iter = treeModel->get_iter (path);
} else {
iter = treeModel->append ();
}
...
Is there a reason why get_dest_row_at_pos() returns null instead of an
empty path? And is there a better way for testing whether a TreePath is
null?
Ferenc
