Re: gtk tree get selected field

[Attila bardi <attila bardi gmail com>]

Hey Peter,

sub button_pressed_event {
       my ($widget, $event) = @_;

       my $treeselection = $tview->get_selection;

       my ($x, $y)=$event->get_coords;
       my $mouse_path=$tview->get_path_at_pos($x, $y);
       if($mouse_path) {
               $tview->set_cursor($mouse_path);
               $treeselection->select_path($mouse_path);
       }

       my ($path, $column) = $tview->get_cursor;
       print $column->get_sort_column_id . "\n";
}

So the get_cursor has update the column if I have a left button
clicked. If I have only the right button (button 3) even if I use the
set_cursor it does not update the column. Is it a bug or a feature?

However I found a simple solution, just I was blind to find it earlier:

(path, column, cell_x, cell_y) = $tree_view->get_path_at_pos ($x, $y)


Cheers,
Attila
