I think GtkTreeSelection may have roughly that internally. Another
possibility would be that ListStore is "iters persist", so convert paths
to iters and the iters stay good.
In my Gtk2::Ex::TreeViewBits I made the few lines below, deleting the
first of get_selected_rows() repeatedly. It probably ends up O(N^2),
but should be safe against anyone mucking about with the selection or
the rows from within the various delete signals.
I can't remember why I return $removed_path. Must have seemed like a
good idea for something -- but then I didn't document it. :-) Maybe
it's to say if anything was in fact removed ...
sub remove_selected_rows {
my ($treeview) = @_;
my $model = $treeview->get_model;
my $selection = $treeview->get_selection;
my $removed_path;
while (my ($path) = $selection->get_selected_rows) {
my $iter = $model->get_iter ($path)
|| do {
carp 'Oops, selected row path "',$path->to_string,'" has no iter';
return;
};
$model->remove ($iter);
$removed_path = $path;
}
return $removed_path;
}
