Trying the first option it seems not recognize sensible option:
GLib-GObject-WARNING **: unable to set property `visible' of type `gboolean' from value of type `gchararray'

With the second option it works, but still visible:

   $tc_pbar->set_cell_data_func ($pbar,
      sub {
          my ($column, $cell, $model, $iter) = @_;

          my $string = $model->get_string_from_iter ($iter);
          if ($string!~/\d:\d:0/) {
              # we should show the progress bar
              $cell->set (visible => FALSE, value => $value);

Is that a typo?  (Should be TRUE here, not FALSE.)

          } else {
              # we should NOT show the progress bar, so don't
              $cell->set (visible => FALSE,value=>22);
               print "pbar to off!\n";
          }
      });

All the 3rd child want to make pbar visible=>false. I tried and i can change the value of all 3rd childs to 22 and it works, but visible=>false doesn't change the state of visibility and i dont understand why because is a attribute og Gtk2::CellRenderer and it should works, but it doesn't.

Any idea?

Perplexing.  A quick scan of the gtk+ sources on git.gnome.org shows that the cell's visible property is honored by TreeViewColumn when processing each row, so this should work just fine.  I may be misreading that (gtktreeviewcolumn.c is 3755 lines and a web browser is not as good for reading code as vim).

Sanity check:  do you have the constants TRUE and FALSE defined?  (e.g. from 'use Glib qw(:constants)').  Is strict turned on?  If perl is not being properly strict, it may be interpreting the bareword FALSE as a string, and 'FALSE' is not an empty string and therefore is logically true.


What if you set the other properties before setting visible, e.g.

   } else {
       # we should NOT show the progress bar

       $cell->set (text => '', value => 0, width => 0, visible => FALSE);
