that requires a knowledges of c syntax that i do not comand.

i think my problem is, that i am more of a dummie than you might assume.
And i think i need to read more documentation before i should bother you with 
concrete and probably stupid questions.
my sources of documentation so far is the misc-examples folder (most usefull to 
me),
gtk+-2.0.9/docs/reference/gtk/html/  and gtk-demo where i found the editable 
cell example.

Now what is my problem exactly ?

for example, i guess that here in the c code example some of the editable cell 
magic happens:


add_items (void)
{
  Item foo;

  g_return_if_fail (articles != NULL);

  foo.number = 3;
  foo.product = g_strdup ("bottles of coke");
  foo.editable = TRUE;
  g_array_append_vals (articles, &foo, 1);
....

now my problem is: what is this foo.editable business exactly ? I know very 
little about c.
so my wild guess is, foo is  a hash (?) and a pointer of that hash then is 
appended to an array ???  
If i could have this example code (Tree View/Editable Cells of the gtk-demo 
example)
in perl syntax, things would be way easier for me. If i could read the c code 
easily, i would probably write my code in c.

           

Anyway this is what i have so far

# define a model
    my $model = Gtk2::ListStore->new(Gtk2::GType->INT, Gtk2::GType->STRING, 
Gtk2::GType->STRING, Gtk2::GType->STRING, Gtk2::GType->STRING, 
Gtk2::GType->STRING,);

# define an iterator
     my $iter = Gtk2::TreeIter->new;

# fill the model with data
     my $i = 1;
 foreach my $name ( keys %names ) {
         $model->append($iter);
         $model->set($iter, [0 => $i++, 1 => "$name", 2 => 
$names{$name}{start}, 3 => $names{$name}{end}, 4 => $names{$name}{ogg_comment}, 
5  => $names{$name}{ogg_artist} ]);
         }
     $iter->free();

# here i build some parent widgets
.....

# now build the treeview widget
        $widgets->{'treeview1'} = new Gtk2::TreeView;
                $widgets->{'treeview1'}->set_headers_visible('1');
                
$forms->{'dialog1'}{'scrolledwindow2'}->add_with_viewport($widgets->{'treeview1'});
   
                my $cell = Gtk2::CellRendererText->new;
                my $column = Gtk2::TreeViewColumn->new_with_attributes("No", 
$cell, 'text' => 0);
                $widgets->{'treeview1'}->append_column($column);
                my $column1 = Gtk2::TreeViewColumn->new_with_attributes("Name", 
$cell, 'text' => 1);
                $widgets->{'treeview1'}->append_column($column1);
                my $column2 = 
Gtk2::TreeViewColumn->new_with_attributes("Start", $cell, 'text' => 2);
                 ...
                $widgets->{'treeview1'}->set_model($model);
                $widgets->{'treeview1'}->show;


i am guessing the new_with_attributes is where it is happening, but what is the 
ciorrect syntax ?

Thanks a lot
